Your brain is just like any other part of your body. In order to maintain optimum function and to get the very most from it, you need to treat it right.
And this is rather important, seeing as your brain is responsible for pretty much everything you do. Whether it’s the obviously ‘mental’ stuff, like concentrating at work or performing complex sums; whether it’s physical stuff like regulating your breathing, helping you sleep and directing your movements; or whether it’s managing your emotions and helping you to feel happy and calm.
Whatever it is you’re doing or experiencing, your brain is at the route of it. And thus you can improve every aspect of the human experience just by focussing on your brain health.
How Your Brain Function Can be Enhanced
The trouble is that many people have very little idea just how to go about looking after their brains. This is the most previous piece of equipment in the world – more powerful than infinite supercomputers – but we tend to just ignore it and hope it all works out okay.
In fact, a lot of the time, we unintentionally subject it to a fair amount of abuse!
For starters, most of us eat entirely the wrong diet and this means our body doesn’t have access to the raw materials it needs in order to maintain optimum brain function. In the short term, this makes us feel groggy and slow but in the long term, it can lead to cumulative damage that results in neurological diseases and age-related cognitive decline. That’s right: it’s not inevitable that you should become forgetful and cantankerous as you get older!
The other problem is that most of us don’t use our brains enough. We don’t challenge them and we don’t train them. Due to a phenomenon called ‘brain plasticity’, it is actually possible for us to train and grow our brains just like a muscle. New neurons can be created and new connections can bef ormed and strengthened. This all means that it’s possible for us to develop certain brain areas beyond others and actually enhance our abilities as a result.
But when you stop challenging your brain or training it, it can lead to all kinds of problems. Especially when you combine that with high levels of stress and the aforementioned poor diet…
Unlock Your Brain’s Hidden Potential
The way that most people eat these days is enough to severely damage our health and lead to serious problems.
As mentioned previously, the brain needs a large number of very specific nutrients in order to function well. These include the all-important precursors to various neurotransmitters. Neurotransmitters are chemicals that change our mood and the way they think – they help us to sleep, to feel good, to focus and to remember things.
But the brain makes these neurotransmitters out of vitamins, minerals and amino acids. If you aren’t getting enough l-tyrosine for instance, then you might struggle to make dopamine – the neurotransmitter responsible for helping us to focus, stay motivated and remember things. Meanwhile, tryptophan is what the brain uses to create the ‘feel good’ neurotransmitter serotonin. This is then later converted to melatonin to help us sleep.
Vitamin B6 is a building block for numerous neurotransmitters including dopamine, epinephrine (focus), serotonin and GABA (calmness). Choline, found in eggs, is the precursor to acetylcholine which can improve pretty much every single aspect of your cognitive function!
Then there are the countless other crucial nutrients that the brain needs to perform optimally. For example, healthy arbs are what fuel the brain with energy, antioxidants protect the brain cells from free radicals and zinc enhances brain plasticity.
But most of us are not getting anywhere near enough nutrients in our diets. That’s because we eat far too much ‘processed foods’. Processed foods contain lots of calories to make us feel full but they are ‘empty calories’ that are devoid of the things we need.
Meanwhile, our switch to a more modern diet that doesn’t include things like fish, mean that even those who try to eat ‘healthily’ are generally not getting the things they need. A perfect example of this is the modern lack of omega 3 fatty acid. Omega 3 is a fatty acid found in fish (and some plants), which aids with ‘cell membrane permeability’ (especially the DHA form). This is important because it allows things to pass more easily through the cell walls – good things like nutrients and signals from other parts of the body. At the same time, omega 3 fatty acid is also used by the brain to create a number of hormones that are linked with managing the blood. This way, omega 3 is able to reduce blood pressure and heart problems.
Most importantly though, this also allows omega 3 fatty acid to reduce inflammation in the brain and the predominance of ‘pro-inflammatory cytokines’. This is highly important, seeing as pro-inflammatory cytokines are what make you feel so groggy and confused when you’re poorly or very tired. Brain fog is a serious problem and it’s made worse by the fact that most of us also have far too much omega 6 fatty acid. Omega 6 fatty acid is a useful nutrient in its own right but when we get too much of it, it can actually lower omega 3 and cause more inflammation. Most of us have far too much omega 6, because it is used in all kinds of preservative oils.
This is then combined with chronic dehydration, which most of us experience on a daily basis. Dehydration can also cause inflammation in the brain, while also generally leading to sluggish performance.
These processed foods are also examples of ‘simple carbs’ – carbs that have no sustenance and which the body processes very quickly. This results in a sudden spike in blood sugar that provides you with a burst of energy, followed by an immediate trough straight afterward.
Then there are all the toxins and high quantities of sugars that we consume regularly – and the cancer causing free-radicals.
Is it any wonder that you struggle to think through the thick haze sometimes?
The Role of Stress
Even worse is the role of stress. Today, it’s a sad fact that a great number of us experience chronic stress, leading to elevated levels of cortisol (the stress hormone) in our systems. This has a number of serious negative effects on our health and on our brain function in particular.
For starters, when there is excess cortisol in the system, this increases the amount of the neurotransmitter ‘glutamate’. Glutamate is a general excitatory neurotransmitter and this means that you’ll experience increased brain activity across the board. This leads to heightened awareness and that sense of nagging thoughts. It also makes it harder to sleep, which can lead to memory loss and depression. But perhaps the most worrying side effect is that ongoing stress also leads to the creation of more free radicals – unattached oxygen molecules that attack the brain cells and potentially cause cancer. It can also generally destroy brain cells, robbing you of your ability to think straight.
Also worrying is that stress depletes levels of brain-derived neurotrophic factor (BDNF). This is the principle neurotransmitter that stimulates the creation of new brain cells and it’s highly important for increasing brain plasticity. In other words, stress prevents you from learning and this in turn is associated with depression, OCD, schizophrenia, dementia and Alzheimer’s disease.
And cortisol also acts contrary to numerous other important neurochemicals. That is to say that when cortisol goes up, these go down. And key victims here are serotonin (happiness), testosterone (drive) and dopamine (motivation and learning).
Just in case that you thought the ‘more alert’ part sounded cool earlier. Note that this also increases your awareness of things like nagging pains, irritating noises and more. This is why stress is associated with tinnitus – the ringing sound some people experience in their ear that has no cause.
And meanwhile, heightened stress can actually cause our frontal cortex – the part used for planning, creativity and higher-order thinking – to completely shutdown.
So in short, stress can absolutely neuter your cognitive ability in the short term and cause long term damage if it is allowed to continue.
The Day You Stopped Learning
All this would be bad enough, if our current lifestyles didn’t also involve so little learning and actually using our brains.
The brain is a tool that has one singular interest: heling us to survive in our environment. And the way it does this is to adapt and to evolve, to enable us to get more reward and less punishment. It helps us seek out food, shelter and sex, while avoiding pain, hunger and fear.
To do this, our brain needs to learn. It predicts outcomes, tries new things and then decides whether or not to do that again based on the response. If it got food, then the neural connections involved in that action are strengthened and it will do it again in future. If it got pain, then the neural connections will be largely overridden and it won’t do it again…
But the brain loves doing this. Learning, exploring and adventuring keeps the brain youthful and nimble and encourages continued growth and the production of more dopamine and BDNF to encourage plasticity.
Once life stops being unique and interesting, the brain stops needing to pay attention and can rely on existing connections. Thus, the things you are already good at get strengthened and everything else gets pruned. You become set in your ways and your brain ceases production of dopamine and BDNF – preventing you from being able to learn new things. And this is when dementia has been shown to kick in.
Now with all this in mind, consider the way your life has changed from when you were younger to now. When you were born, everything was new and your brain was highly plastic. You were constantly learning new things and discovering new things. Thus your brain was filled with novelty and it responded to this by producing huge amounts of dopamine and BDNF. This is why children can pick up languages so incredibly quickly. It’s why they’re always smiling and it’s why they’re always curious and learning.
As we get older, we become more familiar with the world around us. Things get more set in stone and we no longer have to learn simple things like how to walk or what a tree is.
But we’re still learning – we’re learning at school, we’re learning when we watch TV and we’re daydreaming about all the things we could be! This continues to a lesser extent into adolescence as we head off to college and as we start dating for the first time, learn to drive and learn to pay the rent in our own apartments.
Even in young adulthood, much is new as we travel with friends and as we try out different jobs and progress through our careers.
But then things start to slow down. We stop learning new things and we find a job that we like and stay in it. Meanwhile, our bodies become tireder and we gain more responsibilities – like children and mortgages. We settle down in some part of town and don’t move home or environment…
The result is that we end up stuck in a rut and going through the same motions day in, day out. All the while our brain is flooded with stress hormones and we’re eating entirely the wrong diet.
All this contributes to a general slowing of our brain function, damage to our mood and wellbeing and the growing inability to learn. This is why older people are stereotypically more closed minded – they’re literally become set in their way. It’s like taking the same route across a lawn every single day – eventually that route will become entrenched and you’ll never be able to go any other way.
Brain cells start dying, your mood deteriorates and you crawl toward inevitable old-age.
Wow, that’s depressing! The good news is that it’s also wrong.
The inevitable bit, that is. Old age may be inevitable but the cognitive decline associated with it most assuredly is not. In fact, there are plenty of ways you can combat age related cognitive decline and keep your brain youthful and healthy well into older age.
Read on and we’ll look at what some of the things you can do are…
Fix Your Nutrition
Step number one is to fix your nutrition. Instead of eating lots of processed foods, sugary snacks and preserved ready meals, you need to switch to nutrient dense sources of complex, slow-release carbs, to lean proteins, to vegetables and fruits!
This doesn’t mean switching to some kind of fad diet. It just means eating food with real, natural ingredients. And it means seeking out those ‘superfoods’ whenever you can.
If you only add a few things to your diet, consider these:
Eggs are absolutely amazing in just about every way when it comes to your brain and your health in general. For starters, eggs are one of the only ‘complete’ sources of protein. This means that they contain 100% of the essential amino acids that you can’t produce in your body, thereby helping you to produce all kinds of neurotransmitters.
Eggs are also rich sources of selenium, vitamin D, B6, B12, zinc, iron and copper… all things that can boost your brain power.
Best of all, eggs are also high in choline – which is the chemical precursor to ‘acetylcholine’. Acetylcholine meanwhile is a neurotransmitter that helps keep us alert, awake and highly attuned to our senses.
As though that wasn’t enough, eggs are a great source of saturated fats. Saturated fats are also highly beneficial for the brain, seeing as the brain is largely made of fat. Plus it boosts testosterone, which is linked with drive and motivation, as well as mood (and low cortisol).
Tuna is an excellent source of amino acids yet again and is nice and lean for those of you trying to keep their weight down. What’s more, is that tuna is a brilliant natural source of omega 3 fatty acid. We’ve already seen the amazing health benefits of omega 3 fatty acid, so ‘nuff said on that front. Oh and it’s cheap too!
But while tuna is great source of all these things, it is a little high in mercury owing to pollution – so don’t eat more than a small can a day.
Red grapes are high in a substance called resveratrol. Resveratrol is a potent antioxidant, which means that it can prevent the action of free radicals in the brain and thereby reduce your chances of brain tumor or Alzheimer’s. At the same time though, resveratrol is also able to enhance the function of the mitochondria, thereby helping them to produce more energy for your brain cells. It turns out that resveratrol isn’t quite as powerful as some earlier studies suggested but it’s certainly still no slouch either!
Coconut oil contains something called MCT oil – Medium Chain Triglycerides. This is a type of oil that stimulates the liver to produce ketones. Ketones meanwhile are an alternative energy source that the brain can use instead of glucose. The brain actually prefers ketones for a number of tasks, which makes this a great way to give your
If you want to give your brain a little more edge, then you can do so by seeking out a number of different supplements and nootropics. Some good examples include:
Creatine allows the body to recycle its ATP stores. ATP is the body’s primary source of energy and is used by every single cell – including the brain cells. This way, creatine is able to give us more energy to think smarter and improve mental vigilance. It has been shown in studies to increase IQ.
Getting omega 3 from the diet alone can be hard, so supplementing with a DHA product is a good choice. Avoid cod liver oil if you’re pregnant however, due to the large amounts of retinol.
Caffeine will give you a short term boost in concentration, memory and wakefulness. It’s not perfect and can decrease creativity while also being mildly addictive. But it is neuroprotective and can prevent Alzheimer’s.
Finally, don’t forget the power of numerous lifestyle changes. Getting better sleep is absolutely critical to increase neurotransmitter stores, remove adenosine (which contributes to brain fog) and strengthen new neural pathways.
Also very important is exercise. The brain is primarily designed for movement – this is what the majority of brain areas actually specialize in! Moving the body is the best way to learn and to stimulate plasticity, while cardio will also improve circulation to the brain while adding a short term increase in serotonin and endorphins.
Finally, make sure to keep learning, keep exposing yourself to novel surrounds and keep trying new things. Computer games are actually a great way to do this – as every new game includes new environments and new rules to uncover!
Of course we’re only just scratching the surface of what you can do to increase your IQ, your wakefulness, your creativity and your long-term brain health. In the full book, we go into much more depth discussing the huge number of specific brain training techniques, health strategies and more that you can use to start getting more out of your brain and looking after it.
A lot of this is about what you need to stop doing. And it’s about making small changes to your routine and lifestyle – like eating a little more fruit and perhaps walking a little more. Doing small things can make a huge difference to the way you feel now and in the future, it could potentially be the difference that adds 5 or 10 years of quality life. Look after your brain and everything will get better.
So you want to go organic!
Organic gardening does’nt just mean no chemicals, fungicides, insecticides, or herbicides. It means creating a natural balance in our gardens. An organic gardener strives to work with Mother Nature to keep harmony within the natural growing cycle.
There are many ways to start organic gardening. Here are five quick and easy steps to get you started.
Organic gardening starts with soil.
It’s important to know your soil. It’s the life of your garden. Plants require light, air, water, and nutrients. Your soil is the life force that feeds a balanced diet of nutrients to plants that help them fight off insect and soil born diseases
Improving your soil is the first step to organic gardening and that means compost! Compost is not hard once you know how. Just look at our forests and grasslands. Mother Nature composts material everyday to keep a natural balance, yet our forests and grasslands are not buried beneath mounds of uncomposted material. The more time and trouble you put into composting, the less natural it becomes.
Great soil means recycling; recycling plants, weeds, flowers, vegetables, kitchen waste, newspapers and anything else that will break down into compost. Compost is the heart of organic gardening. What goes into the soil comes out as beautiful vegetables, flowers, shrubs and trees. Building and maintaining soil quality is the basis for successful organic gardening.
Start simple. Every garden has composting material. Start by making a pile of weeds you pulled, add trimmings from plants, grass clippings, kitchen waste, spent flowers, straw, hay, newspaper, cardboard boxes, and yes, even your junk mail. (To bad we can’t put our junk email into our gardens). The smaller the pieces the faster it will decompose. Compost really contains all the nutrients plants need for their life cycle. Notice how Mother Nature doesn’t use fertilizer, just good old fashion compost.
If you are an apartment dweller, you can still make compost. A small bucket (or large) can hold your kitchen waste, newspaper, junk mail, pizza crust, and spent flowers and plants. Remember to add equal amounts of green and brown material to make great compost. You can use Batch Banner, Pit-a-Plenty, Trough or Bin composting methods.
If you do not want to mess with making compost, your local landfill usually has compost for free. Just pick it up and mix into your garden. You can also buy compost at your local nursery or garden shop.
Mulch, Mulch, Mulch!
Mulching reduces weeds, saves water and nourishes the soil. Notice how Mother Nature keeps our forests. She drops leaves, branches, and spent flowers on top of the soil and lets them pile up while the bottom decomposes. You can do the same.
Instead of raking up those leaves and throwing them way, run your mower over them to break them up and put them on your plants as mulch. They will not only reduce weeds and save water, they will put back nutrients while they biodegrade. You can also put them in a pile and they will biodegrade while they winter over supplying you with compost in time for spring planting.
Using rock, wood chips, beauty bark, or sand does nothing for the soil. But if you must use them, get them from your local landfill or a tree trimming company. They have tons of it and usually give it away free. Most store bought chips have been processed with chemicals to make them last longer.
Don’t Panic at the First Sign of Bugs!
Pesticides kill almost any bug they touch including the good bugs that prey on the bad bugs. Bug killers do not differentiate between good and bad bugs. They kill them all! Birds, ladybugs, spiders, dragonflies, wasps, praying mantis, and worms eat harmful bugs. Bees and flies are the pollinators of our gardens…so be kind to them and Don’t Panic!
If the bug damage is minor, there is no need to act. Sometimes a weather change or good bugs will take care of the problem. If you must use bug spray, make it a natural one. A little garlic water with a few drops of dish soap will usually take care of the problem. If not, cut the plant back to an inch above the ground and bury it in your compost heap and let it grow back.
Find a natural bug spray you like, or use companion planting. If left alone, Mother Nature usually takes care of her own. The good bugs will come along to eat the bad bugs. If you just cannot stand it, put the buggy plant in a clear plastic bag (after spraying with garlic water), for a couple of days but no longer than a week and not in direct sunlight. Remember though, we need bad bugs for good bugs to survive.
Don’t Waste those Weeds!
It is impossible to rid a garden of weeds! Accept that you will always have some weeds. There, say it out loud…I will always have weeds! Now you can stop trying to get rid of those weeds. Instead of trying to get rid of weeds…use them to amend your soil!
Weeds require the same elements your beautiful garden does; light, air, water, and nutrients. Weeds are just better at pulling these elements from poor soil. If your soil is poor, meaning there is not enough organic matter, you will have a lot of weeds. Weeds find it very hard to grow in good organic soil but that is the way Mother Nature made them.
What we call weeds, Mother Nature calls fast composters. Where it takes a vegetable or flower 60 to 120 days to produce fruit or flower, some weeds can go from seed to flower in two weeks and then start over again. Weeds live and grow to help amend soil faster than leaves or plants because they biodegrade faster.
Weeds can pull nutrients from the poorest of soil but when they die down, they replenish the soil by decomposing and putting the nutrients back where other plants can use the nutrients. So rather than pulling weeds and throwing them away, try tilling them back into the soil to create organic matter that your vegetables need.
Water, Water, Water!
There are chemicals everywhere! The roof of your house has been chemically treated to withstand Mother Nature. The paint on your house is treated with chemicals, your concrete driveway leaches chemicals, your automobile leaks gas and oil, pesticides, weed killers, man made fertilizers, and a host of other chemically treated objects all work to contaminate our water supply. Chemicals disrupt the ecosystem by killing the millions of micro-organism, fungi, and other bacteria Mother Nature uses to biodegrade plant matter. You can help by using these methods to conserve and help purify your water supply.
All plants appreciate a gentle and thorough watering. Letting plants get wilted before watering stresses them and makes them open season for bugs and diseases. Using a slow drip system will supply constant water. A low tech drip system consists of a gallon/liter size juice or milk jug. Poke a few holes in the bottom with a pin, fill it with water and sit it beside your plant, shrub, or tree. Loosen the lid to release the pressure and the water will drip out slowly right where the plant needs it the most; the roots.
Rain barrels are the most efficient of water collectors. Connect them to your downspout to collect water from your roof or connect them together. As the average home yields over 200 gallons of wasted water from the roof, using a rain barrel to collect it will save water when you need it for your organic garden.
Another method is a rain garden or bog garden. Rain gardens are holding areas for water that will not run into our already stressed water sewer systems. It will hold the rain water and let it seep into the ground while purifying it at the same time.
So that’s it…5 quick and easy steps to organic gardening. Mother Nature has provided for us for millions of years by recycling. Recycling plant waste is the basis for organic gardening. It is the heart of Mother Nature and it behooves us to follow her direction for our organic gardens. Good luck and enjoy your organic garden.
It was only a matter of time before the American palate would want more out of its pork. For years, the industry has been pumping pigs full of antibiotics and growth hormones to make them bigger and to keep them alive in the close quarters of factory farms. These inhumane practices, in addition to the use of GMO feed, have led to a decline in the quality of pork products. In recent years, there has been a shift towards more sustainable and humane farming practices, and as a result, pastured pork is taking over the industry.
Pastured pork is pork that comes from pigs that are allowed to roam freely and forage for their food. This results in a leaner and healthier pig, which in turn produces higher quality pork. The taste of pastured pork is noticeably different from that of factory-farmed pork, and many people say it is much better. In addition to being more humane, pastured pork is also more environmentally friendly. The pigs fertilize the pasture as they forage, and their waste is used to compost the fields.
As the interest in local and sustainable foods continues to grow, so does the demand for pasture-raised pork. In fact, pasture-raised pork is now one of the fastest growing segments in the pork industry. There are many reasons for this, but the two most important are that pasture-raised pork is more humane and it tastes better.
Pasture-raised pigs have a more natural diet than pigs that are raised in confinement. They are able to forage for their food, which is mostly plants and roots, and they also eat insects. This diet results in pork that is much leaner and has a more complex flavor than pork from pigs that are raised in confinement.
In addition to being more humane, pasture-raised pork is also healthier for you. Pigs that are confined to small spaces are more likely to be infected with diseases, which can then be passed on to people. Pigs that are able to roam freely are much healthier, and as a result, the pork they produce is also healthier.
If you’re looking for the best tasting and healthiest pork, look for pork that is labeled “pasture-raised”. You may pay a little bit more for it, but it’s worth it. Your taste buds will thank you, and your conscience will be clear knowing that your pork came from a pig that was treated humanely.
The demand for pastured pork is only going to continue to grow as people become more aware of the issues with factory farming. The industry is already starting to respond
Is it that time of year again already? The time when we all reflect on the previous twelve months and set our intentions for the year ahead. If you’re anything like us, you’re probably thinking about all the ways you can improve your health in 2020. And we have the perfect solution: grass-fed beef!
Grass-fed beef is not only delicious and nutritious, but it’s also sustainable. What’s not to love? Here are a few reasons why you should make grass-fed beef a part of your New Year’s resolutions:
-Grass-fed beef is lower in calories and fat than traditional beef.
-It is also higher in healthy omega-3 fatty acids.
-Grass-fed beef is a great source of vitamins and minerals, including zinc, iron, and vitamin B12.
-Eating grass-fed beef is a great way to support sustainable agriculture.
So what are you waiting for? Make 2020 the year you finally make your health a priority and stock your freezer with some delicious, nutritious grass-fed beef

Omega 3 fatty acids are essential to the human diet. They support better health, brain function and retinal health. In particular supplements or food sources of Omega 3 that have high amounts of DHA- docoahexaenoic acid supports and alleviates certain health conditions, like Alzheimer’s Disease and Macular Degeneration. EPA-eicosapentoic acid aids in the reduction of inflammatory diseases and injury. ALA-alpha-linolenic acid also plays a part in the support of human health.
Omega 3 beef is different from typical beef in that it is fed and grass while typical beef is most often grain fed. Which one is better than the other and offers more potential health benefits? Grass is higher in Omega 3 fatty acids while grains that are fed to animals are higher in Omega 6.
Most Americans diets are severely deficient in Omega 3’s and extremely rich in Omega 6’s creating an imbalance. This imbalance is believed to be instrumental in causing
Cancer, ADHD, Diabetes, Heart Disease and other diseases that are caused by body breakdowns rather than bacteria. There are studies being done on human health and what conditions would benefit from treatment with Omega 3’s.
Consumption of grass fed beef has less fat and less calories than grain fed beef. It then follows that Omega 3 beef is healthier and may even aid in weight loss. This red meat is healthier, leaner, and it has been reported to have other health benefits as an addition to ones diet. Unfortunately, grass fed beef is not abundant in the United States although more and more people are switching to grass feeding (pasturing) animals because of the healthy benefits.
The recommended ratio of Omega 6 to Omega 3 fatty acids is 2 to 1 or better. Other positive points regarding Omega 3 beef include it is loaded with natural vitamins and minerals. It is a great source of CLA-(Conjugated Linoleic Acid) a fat that reduces the risk of obesity, cancer, diabetes, as well as some immune disorders. Beef in its natural state and grass fed, not grain fed, allows it to be categorized as a health food. This is a red meat that is actually good for you.
The best source of Omega 3 comes from the Hoki fish that is native to New Zealand.
Omega 3 beef is very rich in Omega 3 as well. Consumers of the Omega 3 Beef report that it tastes like beef and in comparison to grain fed beef has more flavor. It is also free from hormones and antibiotics.
We have found a pure pharmaceutical grade, molecularly distilled
fish oil product that is naturally high in DHA and EPA.
Coming from the Hoki Fish Located on the pristine southern coasts of New Zealand, where the waters are extremely low in pollution and toxins.

Many people may not realize it, but much of the meat we eat contains synthetic growth hormones and other chemicals that may be harmful to us. Why would cattle owners want to use growth hormones? It is all about money. Ranchers today want to produce more cattle in a shorter period. A rancher may only have about 14 months to get the calf from a small size, say 80 pounds, to a selling size (around 1,200 pounds). Growth hormones help the cattle put on weight to get them ready for slaughter in record time as well as reducing the amount of fat in the meat. Nitrates are a chemical compound that can also be found in meat today, being used to cure meat and give them a healthy color. Most notably, nitrates are found in hotdogs, giving them their red color.
The use of hormones in meat is nothing new. As far back as the 1930s, research shows that estrogen affected the growth rates in both cattle and poultry. By the 1950s, a synthetic (man made) estrogen, DES, was being used to increase cattle size. However, DES was found to cause cancer and is no longer used to “fatten” up cattle and chickens.
The Food and Drug Administration (FDA) current approves of five different types of hormones used in food production. Of these, testosterone and progesterone are produced naturally by the animals and zeranol and trenbolone acetate are synthetically made. These hormones are approved for use only in cattle and sheep. Poultry, such as chickens and turkeys, and pigs do not gain much weight when given these hormones, so they are not given them. Most of these hormones are given to the animal by inserting a pellet under the skin of the ear. The pellet releases the hormone and the ears of the animals are thrown away during slaughtered.
The concern of scientist and consumers both is that traces of the hormones and chemicals will remain in the meat and pose a potential hazard to humans who consume it. Have you noticed that girls today seem to be reaching puberty at a younger age? It is suspected that this may be due to the steroids found in today’s meat. Unfortunately, studies done on the potentially harmful ingredients in meat have proved inconclusive and further studies are needed. One problem when conducting a study is that the animals produce some of the hormones naturally, therefore making it hard to determine how much is natural versus the pellet hormones. Also, the level of hormones produced naturally varies from animal to animal, another hurdle for researchers to overcome. The concern with nitrates, used to cure meats and give them a pink or red color, is that they can be converted into nitrosamines. Nitrosamines are believed to both cause and promote cancer. However, the FDA has no studies that decisively finds nitrates used in meats harmful, therefore continue to allow them to be used in processed foods.
What should you as a consumer do? One thing you can do is purchase organic meat. Organic meat comes from livestock raised without hormones or steroids. Also, the cattle are fed grains with no pesticides involved. In 2002, the United States Department of Agriculture developed a system whereas all organic foods (including meat) would be labeled as such. So when shopping, you should see a label on organic meat that signifies that it contains at least 95% organic ingredients. Some grocery stores carry organic meat, but if not, you may have to visit a butcher shop or health food store to find it. You can even buy organic meat through the Internet and have it delivered to your home. However, if you decided to purchase meat online, you may want to first order a small amount. That way, you can determine if it meets all your specifications for delivery time, freshness, etc. before buying a larger quantity.
As ranchers strive to find ways to get more cattle to slaughter faster, consumers will continue to be concerned in the methods they are using to do it. Until more research is done, the best thing you can do it try to be aware of all the dangers out there by staying abreast of the current research being done on cattle hormones and chemicals used in processing meats, and purchase organic meat for your family.
