” I submit that scientists have not yet explored the hidden possibilities of the innumerable seeds, leaves and fruits for giving the fullest possible nutrition to mankind.” - Mahatma Gandhi
Every protein molecule consists of a chain of amino acids. An essential amino acid is one that cannot be synthesized by the body, and therefore must be supplied as part of the diet. Humans must include adequate amounts of 9 amino acids in their diet.
In his book, The China Study, Professor T. Colin Campbell shows that the U.S. RDA for protein is greatly overestimated. Studies of the diets of chimpanzees compared to that of humans confirm the same truth. “Chimpanzees maintain a fairly low and constant protein intake …”[1]
I have looked at the nutritional content of dozens of various green vegetables and I was pleased to see that the aminos that were low in one plant were high in another. In other words, if we maintain a variety of greens in our diet, we will cover all essential aminos in abundance.
I decided to calculate by myself the essential amino acid content in one big bunch of kale and one big bunch of lambsquarters (a weed). I have chosen kale because it is available in most produce markets. Lambsquarters is one of the most common edible weeds that grows in different climates. Most farmers should be able to identify lambsquarters for you.
I then compared the numbers that I got with the amounts of essential amino acids for an average adult recommended by USDA[2]. For more information on the content of Essential Amino Acids in Lambsquarters and Kale, please see page 43 in my book Green For Life www.greenforlife.com
The resulting numbers demonstrated that dark green leafy vegetables contain similar or larger amounts of amino acids than the Recommended Daily Allowance (RDA). However, because of the confusion between vegetables (roots) and greens, we are told that vegetables, including greens, are a poor source of amino acids. This inaccurate statement has led to the malnourishment and suffering of people for decades. The lack of research on the nutritional content of greens has led to a great confusion among the majority of people, including many professionals. Dr. Joel Fuhrman wrote in his book Eat to Live: “Even physicians and dietitians… are surprised to learn that …when you eat large quantities of green vegetables, you receive a considerable amount of protein.”
Where do I get my protein? Being aware of the confusion around vegetables, I understand why this became a popular question. Since most people were not aware that greens have an abundance of readily available essential amino acids, they were trying to eat from the other food groups known for their rich protein content. However, let me explain the difference between complex proteins found in meat, dairy, fish, etc. and individual amino acids, found in fruits, vegetables, and especially in greens.
It is clear that the body has to work a lot less when creating protein from the assortment of individual amino acids from greens, rather than the already combined, long molecules of protein, assembled according to the foreign pattern of a totally different creature such as a cow or a chicken. I would like to explain the difference between complex proteins and individual amino acids with a simple anecdote.
