In my last post I quoted Dr. Bill Sears’ list of the top phyto-rich foods. At the top of the list was soy. Now, I know: soy is controversial, but it needn’t be. His article below explains pretty well why that is so.
Here I want to give Dr. Bill a little more space to explain why soy is top of his list (from AskDrSears.com). I will give you more on how to choose the best soy after Dr. Bill has his say.
“The seven secrets of soy are just a few of the reasons more Americans are trading their sirloin for soy foods.
- A nutrient-dense food. Few foods contain as much nutritional bang for the buck as this bountiful bean. Ounce for ounce, calorie for calorie, the soybean gets top-billing as a rich source of protein, unsaturated fats, fiber, B-vitamins, folic acid, potassium, calcium, zinc, and iron – and it’s cholesterol-free. There is no other single food that supplies so much nutrition in such a tiny package. While TV and print ads tout milk as the perfect food, the soybean actually deserves this title.
- Soy contains powerful proteins, healthier fats. Soy ranks right up there with the American staples — dairy, eggs, and meat – as a rich source of protein, but without the fat drawbacks of these high-protein animal foods. Eggs, dairy, meat, and poultry contain mostly saturated fats, and they are high in cholesterol. Soy fat is mostly unsaturated and cholesterol- free. Soy is the only plant food that is a complete protein, meaning that it contains all the essential amino acids that the body can’t produce. (However, soy does not contain enough of the amino acid methionine for infants and children, so this amino acid is added to soy formulas).
- Soy has intestines-friendly carbs. Since soy is a plant food, it contains no lactose, which makes soy milk, soy cheese, and soy “yogurt” ideal alternatives to dairy products for persons who are sensitive to dairy. Soy contains nutritionally valuable carbs called “fructooligosaccharides” (FOS), which nourish the helpful intestinal bacteria.
- Soy contains mood-friendly carbs. Soybeans have the lowest glycemic index of any food, so they are slow to trigger an insulin response, providing a more stable blood sugar with fewer mood swings from high and low blood sugars. This makes soy an ideal before-school breakfast food for preventing the mid-morning low blood sugar crash in sugar-sensitive children.
- Soy is a terrific source of bone- and blood-building calcium and iron. Soy gets the “Top Bean” award for the two vital minerals calcium and iron, nutritional features that make it a valuable alternative to dairy products and meat. Like other legumes, soy is a rich source of iron, in fact the richest of all the vegetables and legumes.
- Soy is the original health food. Soy is a heart-healthy, cancer-fighting, and immune- boosting food. Comparing the overall health of high soy-consuming cultures, such as the Japanese, and low soy-eating folk, like Americans, provides the first clue that soy has health- building properties. The average Japanese person eats 2 to 3 ounces (50 to 80 grams) of soy food daily in various forms, such as miso, tempeh, and soy milk. The average American eats a scant 5 grams of soy, and that mostly in the form of oils (often hydrogenated) hidden in high-fat foods. Comparing Japanese and American health: the Japanese enjoy a longer lifespan and lower rates of cancer (especially colon, lung, breast, and prostate) and have a much lower incidence of heart disease. It will be interesting to see if a reversal in these diseases occur as we export to the Japanese our beef and they sell us their soy. Heart and cancer doctors believe that adding as little as two ounces of soy to the daily American diet could lower the risk of these deadly diseases. In Oriental medicine, soybeans are valued as the tonic for long life and healthy living. In Oriental countries, soy is known as the “meat without bones” and the “cow of China.” While soy alone won’t save your life, here’s how it can help.
- Soy reduces cholesterol. Research has shown that replacing animal protein with 50 grams of soy protein a day can reduce cholesterol levels by 12 percent. Even better news is that soy protein lowers tryglycerides, reduces LDL (bad) cholesterol, and raises HDL (good) cholesterol. In fact, soy is one of the few foods that selectively reduces LDL cholesterol. Much of the cholesterol-lowering effect of soy has been attributed not only to the soy protein, but also to the fiber and soy phytonutrients (called isoflavones) that work along with bile acids in the intestines to escort cholesterol out of the body. Among the many health claims about soy, it’s cholesterol-reducing effects are the most scientifically proven. So, take your soy to heart.
- Soy contains essential fatty acids. Another heart-healthy feature of soy is the type of oil the soybean contains. Soy oil is over 80 percent unsaturated fatty acids, and soybean oil contains the heart-healthy essential omega 3 and omega 6 fatty acids. (The lack of essential fatty acids in cow’s milk is the reason why formula manufacturers choose soy instead of milk as a source of fat in baby formulas).
- Soy contains cancer-fighting phytos. The phytonutrient most prominent in soy products is genestein, which has been shown to have anti-cancer properties. Soy also contains phytoestrogen, which has been shown to reduce the risk and spread of prostate cancer. The phytonutrient isoflavones are like phytoestrogens that may reduce the risk of breast cancer. The anti-cancer properties of soy seem to be associated primarily with the non-fermented soy products, such as tofu and soymilk, but not with fermented soy products, such as miso and tempeh.
- Soy is a very versatile food. Now that you’ve been shown the joys of soy, you’ll be happy to know that it comes in many forms, catering to different tastes, much like the multiple uses for wheat and dairy. There are many ways to incorporate soy into your diet.
- Soy is known as the anti-aging food. Because of the direct correlation between the longevity of a culture and the amount of soy in its diet, a wise person would, with increasing age, switch from primarily animal protein to fish, plant, and soy proteins. Osteoporosis is almost an accepted fact of getting older. The good news is this does not have to happen. Super soy to the rescue! Research has shown that the same amount of soy that can lower the risk of heart disease (40-50 grams a day) can increase bone density and reduce the risk of osteoporosis. The anti-aging effect of soy is primarily due to its protein content.”
“Eating soy as nature intended (or very close to it) can be beneficial to your well-being in a variety of ways.” says Kris Carr. “Soy protein and omega-3s are important for heart health. They also keep your arteries clear and cholesterol levels low. And contrary to some unsubstantiated fear-based claims, phytoestrogens may actually help reduce breast cancer risk among premenopausal women (more on soy and cancer in the following section). In addition, whole soy foods are easier to digest and taste better than their processed cousins,a and meat.”
Organic, non-GMO, low-processed soy foods – the kind Dr. Sears has in mind – can provide many benefits.
For example, the soy in Juice Plus+ Complete is organic, non-GMO and water-washed (the lowest form of processing possible); it is one of the five sources of 13 grams of protein in each serving. Here are the labels listing the ingredients of the chocolate and vanilla Complete.
