Health Benefits of Grass Fed Beef and CLA: Part 2

Grass fed cows can make wonderful cheeses and butters, which are a good source of natural CLA

In a post a couple of days ago, I gave you a highlight of the benefits of eating grass fed, organically raised beef and animal products (like organic raw milk or cage free eggs), as the essential fatty acid CLA can only be derived naturally from these sources. This time around, I expect to show you the actual research that supports this, and how you can relate it to your own health.

Again, CLA, or conjugated linoleic acid, is an essential fatty acid which is found primarily in meat and dairy products. So, without further ado’, who are the health benefits of grass fed beef and conjugated linoleic acid:

  • CLA and Weight Loss:
  • Many studies are showing the fantastic link between CLA and weight loss, and how it can alter your body composition in a positive way. A study from The American Journal of Clinical Nutrition showed weight loss in overweight individuals with CLA supplementation, equal to 1 pound per month. Combined with exercise and stress reductions, that weight loss could in exceed that limit.

    Another study from The Journal of American College of Nutrition presents that studies performed with CLA and animal models show a decrease in adipose tissue, or body fat, whether or not the animal was eating a low-fat or high-fat diet.

  • Cancer: This study demonstrates the anticarcinogenic effects found in animal foods, or CLA. If you are wanting to reduce your cancer risk, or add another natural method for cancer prevention, then adding CLA to your diet may help.Take, for example, this study, which shows that a small additions of CLA in your diet can reduce your risk for cancer by up to 50%. That is significant, especially if you have a healthy lifestyle already, by exercising, reducing environmental toxins and controlling stress.Another study performed at Kuopio University in Finland with 329 women in a French hospital showed a whopping 74% decreased risk of developing cancer in the women who had higher levels of CLA in their bloodstream.(1)
  • Insulin Sensitivity
  • Researchers at Penn State’s College of Agriculture Sciences found that CLA fed to mice prone to adult onset diabetes decreased overall glucose levels in the blood and an improved insulin action.

    The researcher also goes on to say that one should be aware of the trans-fatty acids in the foods that contain CLA, like dairy and meat products. However, these products do not naturally contain trans fatty acids, unless fried or cooked with partially hydrogenated vegetable oils. He then recommends margarine enriched with CLA. However margarine contains trans-fatty acids, as it is a partially hydrogenated vegetable oil. Hmm. Always be sure to do your own research, because even scientists are always very well educated in nutrition.

    CLA supplements have been shown to worsen insulin resistance, rather than their natural counterparts. So, if you are vegan or vegetarian, it is urged that you try to find a source of CLA in its whole, natural form. Perhaps from raw dairy or cage free, organic eggs.

  • High Cholesterol
  • A study on hamsters found that the group fed a diet of CLA had lower amounts of LDL (low density lipoprotein) in the blood, as well as a reduced risk of developing early aortic atherosclerosis. Currently I can only find studies done on animals, such as hamsters, mice and rabbits. But it does give us an idea of how CLA functions in the body.

  • High Blood Pressure
  • One study on Iranian adults with rheumatoid arthritis showed a significant decrease in blood pressure after CLA additions. Another study on rats (because scientist love their rats) showed a positive decrease in hypertension.

Conjugated Linoleic Acid, or CLA, certainly is a good fat to incorporate into your diet, as these studies have clearly shown. Taking them out completely does not promote good health, so utilizing this fat at least 2-3 times a week is a necessary for me. Even if it is only from eggs or raw, grass fed milk, I know I am doing my body good.
CLA and Supplements: A word of caution on supplements – Many studies show an opposite reaction to all the of beneficial side effects associated with conjugated linoleic acid. This is where you will have to do your own research and find that CLA from natural sources, such as grass fed butter, milk, eggs or meat, is your better option. Talk to a trusted nutritionist for more information on this topic.
I hope to provide a series of recipes that can be of good use for both vegetarians and meat eaters alike, who are wanting to incorporate more CLA in their diets. Until then…

Can Beef Be Healthy? – The Health Benefits of CLA (Conjugated Linoleic Acid)

*Please click the links provided in the post to read studies on conjugated linoleic acid

What if you could eat your beef, yet remain healthy? What if you could eat eggs, chicken, turkey, etc., but still maintin a low body weight? Conjugated linoleic acid, an essential fatty acid found in these products may provide these healthy benefits, and more, according to numerous studies on the fatty acid composition and its relation to human health.

There are many studies linking meat consumption with cancer, diabetes and a host of other health problems that stem from an unhealthy lifestyle and bad dietary habits. However, many of these studies are indicating factory farm animals, who have been fed GMO (genetically modified) grains, promoting higher levels of omega-6 fats in their blood (inflammatory fats—high livels have been shown to contribute to cancer cell growth). These animals are also pumped full of antibiotics to keep them from getting sick due to their stressful environment, and growth hormones to increase the rate of growth in the animal. I don’t know about you, but all these things don’t really sound health promoting.

This might be the reason why many studies link cancer with meat eaters. But what if there was a way to avoid all meat containing these unhealthy additives and fats, meat that was organically raised, free range and ate the diet their bodies were designed to eat? Would they be healthier, and would our health reflect theirs? Most possibly, especially when you look into the research done with grass fed beef and animals and CLA, or conjugated linoleic acid.

What is CLA?

CLA is an essential fatty acid. This means our body cannot manufacture CLA on its own, and we need to obtain it from our diet. The foods high in CLA include eggs, beef (specifically grass fed beef), chicken and turkey. Finding CLA in vegetable sources is nearly impossible, unless you want to consume corn oil (eek!), which is especially high in omega-6 fats.

CLA has been shown in recent studies to fight obesity, reduce the risk for cancer, help you lose weight, improve immune function as well as fight diabetes. An amazing list that you don’t immediately jump to when you think about eating meat.

There are many naysayers about consuming beef, especially because of the deplorable conditions factory farm animals are kept throughout their short lives. In my opinion, this form of farming has to go, and replaced with a slowly growing movement of free range, organic farming, which lets the animals roam freely on a diet that will promote their health (rather than being fed grain—an unhealthy food that promotes inflammation, and one that they would never eat in nature).

Animals who are free range typically live longer than animals who are on factory farms, and tend be healthier without the use of antibiotics. Organic, free range cows are especially high in CLA, afat which has been shown to fight cancer and belly fat. In fact,you don’t necessarily have to consume grass fed beef too often to receive its health benefits. Free range, cage free organic eggs also provide a high amount of CLA (but not as much as grass fed beef).

The Health Benefits of CLA

This is Part 1 of a two part series on CLA. The benefits of conjugated linoleic acid will cover an entire post (in fact, probably even two posts!), so I will retain the benefits of this healthy fat until tomorrow. However, here are a few bullet points (which will be followed with the studies that validate the claims in the following post) that show the health benefits of the essential fatty acid, CLA:

  • Reduces the Risk for Cancer
  • Fights Diabetes
  • Fights Abdominal Obesity
  • Reduces High Triglyceride Accumulation

Healthy Weight Week Day Two: Your Exercise Program

Yikes! Exercise might seem scary for some–heart pounding moves that promote sweat, burning muscles and a tight bod. OK, I couldn’t think of a third promoter of exercise that sounded bad. Actually, all of those sounded quite good to me, and might to your, too, if you exercise regularly and feel the benefits of your daily movement.

Exercise not only promotes a healthier body figure and weight, but it also plays vital roles in various other physical and mental parts of your body. Daily movement and exercise influences cells in your body, preventing them from erosion and death, and also aids in proper mental agility and function. First I will go over what exercise does for your body, before I get into what exercises to do for the health of your body.

  1. Exercise promotes better sleep. If you are looking for a natural way to help you sleep at night, without the use of over the counter or prescription drugs (which can lead to dependancy), then exercise is your way to go. Exercise at least 30 minutes a day (45-60 minutes is optimal, depending) will provide an energy expenditure that will promote a tired sensation at the end of the day, thus promoting sleep. This will also last for many hours, preventing you from awakening during the middle of the night.
Besides the obvious effects exercise has on sleep, we also find it affects our circadian rhythms. Our circadian rhythms are the biological rhythms that occur throughout a 24- hour period. The circadian rhythm is mainly focused around our sleep hormone, melatonin. This hormone rises in the evening when darkness sets (making us feel tired and sleepy), and decreases during the day. This hormone is secreted much more strongly when exposed to natural sunlight, as proper sun exposure to the eyes and skin during the day help influence a stronger increase in the hormone at night.
Studies have shown that regular physical activity increases the level of melatonin that issecreted at night. A study performed at Mount Sinai Hospital in Toronto, Canada, found that exercise increased levels of melatonin secretion, especially if the exercise was performed later in the day. However, I believe that exercise in the morning to be optimal. But, if you are trying to fall asleep naturally, break up your exercise routine during the day, morning and afternoon. Exercising too close to bed time, inversely, will actually inhibit your sleep, according to this study.

2. Healthy exercise promotes a better mood, and helps fight depression.
Exercise is one of the most powerful natural “drugs” available, and it is incredibly effective in combating depression and mood disorders. When we put a healthy exertion on our bodies, as through exercise and movement, we start to release hormones in our brain, namely serotonin and endorphins–“feel good” hormones). The endorphins that are released have similar effects as morphine, but without the risk of dependancy. Neurotransmitters are also released to provide the transport of the hormones throughout your mind and body, elevating your mood. Too much exertion, however, can have an opposite effect.
The Mayo Clinic also states that exercise boosts mood by elevating body temperature (a warmer body temperature has a calming effect) and increasing the immune system, which has been linked to mood, as well. A study reported in the American Journal of Preventative Medicine used exercise as the only treatment for depression, and found that depression symptoms were cut almost in half in the subjects who participated in the 30-minute aerobic exercise sessions.
3. Fights cancer, heart disease and diabetes. Exercise lowers insulin levels and makes your bodies cells more sensitive to insulin. I believe insulin resistance to be one of the culprits behind the rise of degenerative and preventable diseases seen in America today. Lack of exercise and poor diet can lead to these complications, and exercise has been shown numerous times to prevent these illness, and even some controversial evidence suggests it can help reverse them (I am NOT condoning a treatment plan–only an alternative preventative strategy!).
4. Makes you smarter. Exercise has been shown to grow new cells in the brain, and also strengthens the inner cortex within the brain associated with cognition and attention. Using exercise as a tool for ADD or ADHD (learning disabilities that I really don’t believe exist) along with other healthy approaches (diet, sun exposure, proper sleep and hydration, etc.) can be incredibly beneficial. It always amazes me to see that moving your body every day can actually grow brand new, physical parts of your brain. This is very important as we age, and even for us college students (and all students, everywhere)!

5. Helps fight off illness. Exercising activates the immune system, helping your body fight off illness. The #1 issue people have when they get colds or the flu is that there immune system is down or not functioning properly. Exercising and eating right improves the immune system dramatically.
6. Promotes a healthy body weight and appearance. To be healthy, and to weight less (or more, depending on your needs), it is absolutely crucial that you apply exercise to you life. It is a valuable key nutrient that helps speed up your basal metabolism (how many calories you burn at rest), activates your growth hormone secretion (from the pituitary gland in the brain) and leads to greater flexibility and strength by toning the muscles and bones.
Like I said before, exercise is a powerful natural “drug” that most people have available to themselves and that can even replace dangerous, and often expensive, conventional drugs. Many stuides already show that antidepressants don’t work, so why risk the side effects and pay the price (mentally, physically AND monetary)?
Since I am talking about how to move into a healthier weight with exercise, let’s go over the types of exercise that are best. Each type of exercise won’t address weight loss, but will, overall, make you healthy. A proper balance of each type will keep your insulin and weight levels low, your energy high and your muscles and body toned and fit.
  1. Interval Training. This is a really cool type of exercise that I’m extremely fond of. Recent research has shown that interval training is the best way to burn fat. This exercise combines intense cardio bursts with periods of rest in between. In fact, the “rests” are actually smaller, less intense movements of the intense cardio movements. Let’s say you are walking. For 30 seconds you will do intense sprinting across your path. Then you will go back to walking for 60-90 seconds. Then, you will do the same sprints (bursts of cardio) for 30 seconds. Now back to the walking for 90 seoncds, and so on and so forth.
According to Darrin Steen, health and fitness expert, our bodies continue to burn more calories at rest up to 8 hours after an interval training exercise! This is amazing, seeing how after most aerobic cardio, like light jogging, your body’s metabolism slows back down again. However, your metabolism stays elevated much higher after an interval style cardio exercise. You can jump rope, do jumping jacks, or perform sprints for this exercise– anything that will be intense enough to do for 10-30 seconds. 20 minutes of this exercise is usually enough to compare to an hour’s worth of jogging (cardio bursts and rests).
Push yourself HARD during the 10-30 seconds of burst activity to start seeing results and reduction in your weight, to to see a more toned, fit body. Your body produces adequete amounts of growth hormone with this type of exercise which slow down the aging process, increases muscle mass and aids in reducing fat. Doing too much of this good thing will cause an opposite effect and make your body store more fat by producing cortisol, the stress hormone. 20-40 minutes every other day is fine. However remember–this exercise is best performed every other day, so that you can incorporate other forms of exercise into your lifestyle and to prevent injury.
2. Resistance training. This type of exercise involves using weights, or your own body weight, as resitance in sculpting your body and your muscles. Lifting weights is the common way to go, but you can also find something handy and heavy to use instead. To have a lean body, to have a muscular body, to be fit and have a sculpted look, resistance training is a must. Watch the video below to see an example of this type of exercise.

Please start off with smaller weights if you are just beginning.
Building muscle mass helps your body burn more calories at rest, helping you lose weight faster. However, like interval training, this should be done every other day. Exercising the same muscle groups day after day can result in injury. It’s always important to alternate your exercise routine for optimal health.
3. Core exercises and flexibility. These exercises (yoga, pilates, stretching techniques) focus on the core abdominal muscles, promotes balance and flexibility. It is always important to round your exercises off with stretching, and even more important to incorporate a flexibility routine, like yoga and/or pilates, into your practice. My favorite form of yoga is Vinyasa yoga, which combines cardio moves with yoga poses.
The Take Home

Like I said before in my descriptions of the exercises above, it is always important to involve every single one into your healthy lifestyle. Only doing cardio for hours on end will result in energy drainage, increased production of free radicals and cortisol (thus increasing the rate of aging, disease and fat storage), and will provide no enjoyment in the long term. Starting off with just cardio is also more likely to deter you away from exercise later on due to the energy burnout.
For optimal fat burning and muscle building (and for a healthier you), alternate interval cardio with strength and resistance training throughout the week. If you are already at a healthy weight, don’t have insulin or cholesterol problems and don’t need or want to gain/lose weight, then 3 times a week of exercise will suffice. I like to strive for physical activity every day, but only push my body to the point it feels where it needs to go. Listen to your body, and your body will thank you.
On Friday I will have Day Two posted, telling you about healthy foods that will boost calorie burning, help sculpt muscles and promote optimal nutrition. It isn’t just about reducing or adding calories–exercise is a critical nutrient that will help sculpt your body in a healthy way.
I wonder how many times I can use the word, “healthy”, in a paragraph? Count them all up in this post and win a prize! 🙂
