Can Soy Products Substitute for Meat ? In many countries,
soy protein isolates (SPIs), have been utilised as a powdered meat replacer.
Using one part SPI and three and a half parts water, it is possible to obtain
vegetable “granules”, with a similar texture to meat. These granules can be
coloured with suitable ingredients, for example with fermented rice, caramel,
and red carmine, and used “as meat” in economy formulations, in quantities
ranging from 20% to as high as 50% of a final meat product. SOY VS. MEAT For starters, a diet that limits fat-laden beef and pork proteins and emphasizes plant protein is automatically better for your health. * You avoid the artery-clogging cholesterol and saturated fat inherent in four-legged meals. * You also consume more fiber, which keeps your lower intestines in working order, which means you'll be lowering your risk of colon cancer. * What's more, soy is rich in isoflavones, a class of phytochemicals thought to contribute to many of soy's protective effects. Soy also matches meat for protein quality. Soy protein contains all nine essential amino acids (essential because they are not synthesized within the body). This complexity of amino-acid structures is crucial if one of your goals is to build muscle. However, when you take a bean like soy, your body will always try to use that bean as a starch first, and then convert what's left over to usable proteins. In meats, there are no carbohydrates that your body has to deal with and break down. Meat proteins are always more efficiently utilized than vegetable proteins. In the end, experts suggest that meat eaters replace only some of their daily meat intake with soy, especially if they're concerned with both health and muscle growth. To get all the health benefits of soy, the Food and Drug Administration suggests the following: * Eat 25 grams of soy protein a day (see "Soy Protein, by the Numbers, above). You can get those 25 grams by consuming four servings of foods that display the FDA's soy-health imprimatur on the front panel, which means they contain at least 6 1/4 grams of soy protein per serving. * Since you still need close to one gram of protein per pound of body weight, you can get your remaining 100-plus grams from meat (or other plant sources if you're a vegetarian). * Soybeans, tempeh and tofu are all good sources of soy protein, but forget about popping pills. "It's important to get soy in a whole-food form," says Hall. "It can be in a powdered form or as a meal replacement, but not in a pill form. There are things like phytochemicals and antioxidants in soy foods that don't have a scientific name yet, and they're not in the pills."
