Soy protein vs. meat protein is a concept that nutritionists and health care professionals debate regularly. Vegetarians tout the health benefits of soy while meat-eaters insist on the benefits of meat. Both soy and meat protein have pros and cons, but animal and vegetable protein more than likely have the same effects on the body, says the Harvard School of Public Health.
Benefits
According to BodyBuilding.com, soy contains all of the amino acids that make it a sufficient substitute for meat. They propose that soy protein lowers the risk of heart disease, reduces LDL cholesterol and raises the nutritional value of other foods. Due to the hemoglobin in meat, the nutrient iron is more easily absorbed by the body. Zinc and B vitamins are potent in meat products. Meat protein also helps with the formation of body tissue.
Theories/Speculation
According to the MayoClinic.com, meatless meals and eating less meat have great health benefits. Vegetarians consume more soy products than non-vegetarians. Generally, vegetarians and vegans live longer lives, have fewer health problems and struggle less with weight. It is recommend that you eat at least one to two meatless meals a week. When you do eat meat, do not overindulge and eat lean meat as much as possible.
Warning
Soy protein and meat protein both come with their own set of warnings. According to Food Renegade's article, "Dangers of Soy," this plant may have negative effects on the body. The article says soy can harm the thyroid gland, block mineral absorption and may prevent the body from properly digesting protein. However, the harmful effects of meat are more widely known. The "Atkins Diet Alert" suggests that large quantities of meat, especially red meat, can lead to heart disease, contribute to calcium loss and may cause kidney abnormalities.
Misconceptions
One misconception about soy protein concerning men is that it lowers testosterone and increases estrogen. This rumor is rooted in the fact that soy contains phytoestrogen, a type of plant estrogen. These phytoestrogens do not lower testosterone and increase estrogen, but rather they contain the health benefits that make soy popular, writes EdgeBoston.com.
Considerations
A good mixture of proteins is best to ensure you get all the amino acids your body needs. The best choices for meat protein are fish and poultry. If you prefer red meat, it is important to focus on leaner cuts to avoid excessive saturated fat, says the Harvard School of Public Health in the article, "The Nutrition Source Protein: Moving Closer to Center Stage."
