Vegan Problems…
I’m considering going vegan for Lent, but I knew I would have to pass the idea through my mother. She instinctively opposed the idea. “How will you get enough calcium and protein?” she asked. Good question. Well, I knew that legumes and whole grains have lots of protein, but I’m not crazy about the idea of eating rice and beans all the time, so I decided to research plant-based sources of protein. My findings conflicted with any preconceived notions that I had about healthy protein intake. I read a chapter of Rosemary’s “Thrive” book (“The Vegan Nutrition Guide to Optimal Performance in Sports and Life”) which talked about the body’s method of protein absorption. Our bodies only use a certain amount at a time, so animal proteins (including dairy and eggs) are excessive. Plant sources provide the most efficient source of protein.
Today, we watched a documentary called “Forks Over Knives” and it discussed a study of the effects of protein on lab rats. The rats that were fed diets that included 20% protein had much higher rates of tumor growth and various cardiovascular diseases. This was a bit shocking to me– I’ve been a pescatarian for almost two years, and I’ve always made sure to eat enough healthy sources of lean protein (e.g. fish, greek yogurt, eggs, cottage cheese). With all the food and lifestyle-related cautionary tales out there, there’s no such thing as too much research. So I’ve started to research this question of plant vs. animal-based protein in greater depth.
My findings so far have been surprisingly consistent. According to several websites (a few of which I will post below), plant sources easily supply our need for protein. Meat does have more protein than vegetables, but that is an excess– it is not necessary for our health and, in highly excessive quantities, can actually be extremely detrimental to overall health. This concept is totally new to me, and I will continue to research. I have to say, the statistics and testimonials I have read so far have seemed legitimate and been very convincing.
