Nutrition 101

April is National Soy Foods Month.

The soybean is a legume and part of the pea family. The soybean is the only plant-based protein that contains all the essential amino acids found in animal proteins. Soybeans are free of cholesterol and are low in saturated fats. Soybeans contain fiber, iron, calcium and many other vitamins and minerals. In addition, soybeans are rich in isoflavones, a plant estrogen. There is ongoing research that supports the beneficial nutritional qualities of soy protein and isoflavones, from heart to bone health. To be fair, there is also controversy regarding soy with respect to thyroid disease and breast cancer.

Based on recent clinical and epidemiological studies, recommendations for adult intake of soy protein is 15-25 grams per day or 2-4 servings of soy foods per day.

FYI – A serving of soy foods is 1/2 cup tofu; 1 cup soy milk; 1/4 cup edamame; 1/3 cup soy nuts; a soy-rich burger or protein bar. 

Many soy products are excellent options to include in a healthful diet. Soy products may be high in protein and high in fiber, vitamins, and minerals. However, it is always important to read labels, look at ingredients and review sodium, saturated fat and sugar content.
