Soyfoods Nutrition Information

lthough soyfoods are widely recognized for their nutritional qualities, interest in soyfoods has risen recently because scientists have discovered that a soy component called isoflavones appears to support a variety of healthy tissues.

One cup of soymilk contains about 25 milligrams of healthy isoflavones. Because of new research showing greater health benefits with greater isoflavone intake, we recommend Revival Soy shakes and bars. Each Revival Soy shake or bar contains 160 milligrams of soy isoflavones because of a patented natural concentration process. You would have to drink about 6 cups of soymilk to get this level of isoflavones. Learn more.

Scientists with USDA's Agricultural Research Service have compiled a database that gives values for the major isoflavones in 128 soyfoods and ingredients. Isoflavones, The new soy isoflavone database can be found on the web at: http://www.nal.usda.gov/fnic/foodcomp/Data/isoflav/isoflav.html

The calcium content of fortified soymilks which may be found in retail stores can be found in our Soymilk Calcium Chart.

It is important, though, to understand the entire nutritional value of specific soyfoods so that dietetic decisions can be made. For instance, soy protein has been found to be effective in reducing cholesterol, in supporting kidney health, and may cause calcium to be better utilized, helping to support bone health. Some soyfoods such as miso contain high amounts of sodium, and should be avoided by people who need to minimize their sodium intake. A single serving of tempeh contains twice as much fiber as the average American eats in a day.
