Where’s the Protein? Where’s the Beef?: Part 2

I will now continue from yesterday’s article, which was Part 1 of this two-part series. In that article I discussed what are our protein needs on a daily basis, and that we can meet all our needs with a diet of no or less meat.

I left off talking about foods from the vegetable world that are good sources of protein. Interestingly, I said that 100 calories of spinach contains more protein than 100 calories of steak.

Another powerhouse protein food is the grain quinoa. Quinoa is not only high in protein, but it is also a complete protein, meaning it contains all nine essential amino acids. Vegans and vegetarians concerned with protein intake should incorporate this healthy grain into their meals.

Quinoa is also a good source of magnesium, iron, copper, phosphorous and is well-endowed with the amino acid lysine, which is essential for tissue growth and repair.

Cooked soybeans are another good food, and they rank 10th on the World’s Healthiest Foods Containing Protein List beating out eggs, all dairy and most meats. In the nutritional community, soybeans are regarded as equal in protein quality to animal foods. One cup of soybean provides approximately 57.2% of the daily value for protein for less than 300 calories and with only 2.2 grams of saturated fats.

Studies have also shown that soy helps reduce cholesterol levels while consumption of animal proteins makes cholesterol levels rise. Soy is also rich in iron, magnesium and omega-3 fatty acids.

Soy can also be found in a variety of forms such as soy milk, soy yogurt, soy cheese, soy ice cream, tempeh, meat substitutes, miso, soy protein powder and tofu.

Other foods that are excellent sources of dietary protein include mustard greens, artichokes, corn, lentils, nuts, seeds, hot cereals and other beans.

Now, let me switch gears a little and go back to a theme that I touched on two days ago with my article about the vegan bodybuilder Kenneth Williams. As I said in that article, a common misperception is that to be an athlete you have to eat a meat-based diet and that there’s no way you can be vegan/vegetarian.

Well, consider the following list of current vegan and vegetarian athletes: Prince Fielder (MLB), Tony Gonzalez (NFL), Mac Danzig (Martial Arts), Pat Neshek (MLB), Scott Jurek (Ultra marathoner), Brendan Brazier (Iron man), Kenneth Williams (Body Builder), Christine Vardaros (Cyclist). Other vegan and vegetarian athletes include: Peter Brock, Carl Lewis, Salim Stoudamire, Ricky Williams, Ed Templeton, Bill Pearl (former Mr. Universe), and many other Olympians, world record holders and top athletes.

Most athletes take protein powders, and vegan and vegetarian athletes can also supplement with soy, brown rice and hemp protein powders.

Finally, I want to say a word about protein consumption in general. As I mentioned in yesterday’s Part 1, Americans eat way too much protein.

According to U.S. RDA calculations, the average person in America consumes 100 to 120 grams of protein per day, with the majority of it coming from animal sources. As I reported in yesterday’s article, the U.S. RDA states that an individual on a 2,000 calorie diet only needs 75 grams of protein – that means that the average American is consuming an excess of 25 to 45 grams of protein per day.

An excess of protein, particularly animal protein, is exceptionally harmful to the body. This was the findings of The China Study, and I talked about the findings of this landmark study in an earlier article.

I’ll sum it up again: The China Study examined the relationship between the consumption of animal products and diseases such as cancer, diabetes, heart disease, osteoporosis, autoimmune diseases, obesity and other degenerative diseases.

The authors of the study concluded that based on long-term scientific studies, diets high in animal proteins from both meat and dairy are strongly linked to heart disease, cancer and type 2 diabetes. The authors recommended a whole food, vegan diet as a means to minimize and/or reverse the development of chronic diseases.

Excess protein, especially coupled with America’s sedentary lifestyle, can also be taxing on the kidneys. Animal proteins are inherently stressful on the kidneys, but overages will cause the kidneys to underperfom. When the kidneys are not operating optimally, the risk for premature aging or developing kidney stones sharply increases.

Bone health is also effected by excessive protein consumption. Excess protein consumption causes calcium to be leeched from the bones, which may then cause osteoporosis, acid reflux, obesity, plaque build-up in the arteries, high blood pressure, high cholesterol, and arthritis.

So there you have it. If you are eating vegan or vegetarian, or you are eating not much animal-based foods, the next time someone asks you how can you be getting enough protein, you’ll have plenty of ammunition to counter back.

Where’s the Protein? Where’s the Beef?: Part 1

Yesterday’s article was about vegan bodybuilder Kenneth Williams, and his busting of the myth that in order to build muscle and be an athlete you need to eat animal protein.

I wrote this article not necessarily to encourage you to become vegetarian or vegan as much as to show you that eating animal foods is not the key to feeling strong and vital, and that you can do the same (actually better) with a diet of less or no animal foods, because there are health issues inherent with a diet that stresses animal foods.

As I pointed out in the China Study article, a diet high in animal foods is detrimental to the health.

Also, a diet high in animal foods is not conducive to living a
Low Density Lifestyle.

Protein is synonymous with strength, and so it is assumed that in order to build strength and be an athlete, you need to eat protein, and since it is assumed that meat is the best source of protein, the thinking is that you need to eat meat to achieve your goals.

It is also thought that if you don’t eat meat, or don’t eat enough meat, whether you are an athlete or not, you will not get enough protein and therefore become protein deficient.

One of the most common questions anybody who doesn’t eat animal foods gets is “where do you get your protein?”

Like carbohydrates and fats, protein is one of the essential building blocks of the body. It is an essential nutrient needed by the body in order to function properly. Protein’s primary function is to build and repair muscles but it also keeps the immune system functioning properly and is involved with the synthesis of hormones and enzymes.

Protein may also be used as an energy source when there has been insufficient carbohydrate consumption.

Protein is made up of 20 building blocks, known as amino acids. Amino acids are classified as essential and non-essential amino acids. Essential amino acids are not created in the body and therefore must be consumed through dietary protein.

How much protein do we need? There are two ways to calculate total protein needs. The U.S. Recommended Daily Allowance (RDA) for protein is 0.4g of protein for every pound of healthy weight (or approximately 0.8g per every kilogram of weight). For example, a man who weighs 150 pounds needs approximately 60g of protein per day (150 x. 0.4 = 60).

Alternatively, protein can be calculated based on total caloric intake. Generally, 15 percent of total caloric consumption must come from protein. For example, on a 2,000 calorie diet, 300 calories must come from protein. To determine the number of grams needed, divide the resulting number of calories by 4. Thus, on a 2,000 calorie diet, 75 grams of protein must be consumed.

Since one ounce equals about 28 grams, the body actually needs very little protein to function properly – we need less than three ounces a day of protein.

As I said above, protein is commonly associated with animal foods – meat, eggs and dairy products – but these foods are not the only sources of protein nor are they necessarily the best sources for protein. Protein is found in every food. Fruits, vegetables, grains, nuts, seeds and legumes all contain protein.

It is impossible to become protein deficient eating a well-balanced vegan diet, largely due to the fact the body needs very little protein to perform. For example, one cup of black beans contains 15.2 grams of protein (roughly 30.5% of the daily value for protein), plus approximately 74.8% of the daily value for fiber. The total calories for a cup of black beans is only 227 calories and there is virtually no fat. Similarly, 100 calories of spinach contains more protein than 100 calories of steak.

Spinach also delivers a boost of fiber, anti-cancerous properties and iron for only a small amount of calories and no fat. Steak on the other hand, which not only provides less protein and no fiber, also contains saturated fat and harmful cholesterol.

I will be back with tomorrow with part 2 of this article. So tune in tomorrow…

What the China Study Says About Eating Meat

I told you in yesterday’s article about several studies that showed the downside of eating meat, including a recent one concluded in the U.S. that studied 500,000 people.

Today I will tell you about the landmark study that sealed the deal for once and for all about the dangers of a diet top-heavy in animal foods.

This study was reported in the best-selling book, The China Study.

The China Study, published in 2005, was written by T. Colin Campbell, Ph.D., and his son, Thomas M. Campbell II, and is the definitive report about the detrimental effects of eating meat.

Dr. T. Colin Campbell is a professor of Nutritional Biochemistry at Cornell University and one of the directors of the China Project, which was the study that “The China Study” reported on.

The China Project is a survey of death rates for twelve different kinds of cancer for more than 2,400 counties and 880 million (96%) of China’s citizens, conducted jointly by Cornell University, Oxford University, and the Chinese Academy of Preventive Medicine over the course of twenty years.

The book examines the relationship between the consumption of animal foods and illnesses such as cancers of the breast, prostate, and large bowel, diabetes, coronary heart disease, obesity, autoimmune disease, osteoporosis, degenerative brain disease, and macular degeneration.

The authors conclude that diets high in protein, particularly animal protein (including casein in cow’s milk), are strongly linked to diseases such as heart disease, cancer and Type 2 diabetes.

The authors recommend that people eat a whole food, plant-based diet and avoid consuming beef, poultry and milk as a means to minimize and/or reverse the development of chronic disease.

In the book, Dr. Campbell stated that “several studies have now shown, in both experimental animals and in humans, that consuming animal-based protein increases blood cholesterol levels. Saturated fat and dietary cholesterol also raise blood cholesterol, although these nutrients are not as effective at doing this as is animal protein. In contrast, plant-based foods contain no cholesterol and, in various other ways, help to decrease the amount of cholesterol made by the body.”

He also stated that “these disease associations with blood cholesterol were remarkable, because blood cholesterol and animal-based food consumption both were so low by American standards. In rural China, animal protein intake (for the same individual) averages only 7.1 grams per day whereas Americans average 70 grams per day.”

He concludes by stating that “the findings from the China Study indicate that the lower the percentage of animal-based foods that are consumed, the greater the health benefits—even when that percentage declines from 10% to 0% of calories. So it’s not unreasonable to assume that the optimum percentage of animal-based products is zero, at least for anyone with a predisposition for a degenerative disease.”

The authors state that autoimmune diseases are more prevalent among people who consume a diet high in animal protein, particularly cow’s milk.

They also state that the consumption of animal protein, especially cow’s milk, result in higher concentrations of Calcium in the blood, which inhibits the process by which the body activates Vitamin D in the kidneys to a form that helps repress the development of autoimmune diseases.

Dr. Campbell then goes on to list various diseases that are linked to a diet high in animal protein. These include:

Autoimmune Diseases

Brain Diseases, including cognitive impairment, demential and Alzheimer’s.

Breast Cancer

Colorectal Cancer

Diabetes

Eye Diseases

Heart Disease

Kidney Stones

Metabolism and Incidence of Obesity

Osteoporosis

In concluding the book, Dr. Campbell stated that one of the biggest impediments to wholesale dietary changes in the U.S. “are powerful, influential, and enormously wealthy industries that stand to lose a vast amount of money if Americans start shifting to a plant-based diet.”

And so, there you have it. The most definitive study ever done on the profound detrimental effects of eating a diet that emphasizes animal food.
