Many of us are aware that isolated soy protein, soy protein isolate etc is a highly processed food that is a far cry from natural soy products such as tofu, miso or tempeh.

What many are unaware of, is that manufacturers who use imported isolated soy protein from countries such as China do not have to say so on the label.

This is a potentially huge issue since the ingredient is found in many products

such as veg. hot dogs, veg burgers, energy bars, protein powders etc.

I have more details in my blog post at http://givingupcontrol.wordpress.com

Producers of soy protein isolate, a high-protein supplement that comes in powdered form, promote it as an aid for gaining muscle and improving body composition. This plant-based protein supplement provides all of the essential amino acids needed to repair build and maintain body tissues, according to the University of Illinois. Consult a doctor prior to using any supplements.

Calories
As a low-calorie supplement, soy protein isolate can help you shed some excess pounds. Each serving contains 120 calories, which comprises just 6 percent of the daily suggested intake of 2,000. You can easily burn the 120 calories with exercises, such as a 12-minute jog or a 14-minute swimming session.

Recommended Serving
According to the Food and Drug Administration, consuming 25 grams of soy protein per day may lower your risk for heart disease. Four ounces of firm tofu contain 13 grams of soy protein, a soy burger contains about 10 to 12 grams and 8 ounces of soy milk contain 10 grams. However, when you eat 25 grams of soy protein you consume 45 milligrams of isoflavens. Pennsylvania State University College of Agricultural Sciences reports the weak estrogen content of isoflavens may increase your risk of cancer if you consume more than the safe upper limit of 100 milligrams per day. Fifty-five grams of soy protein contain 99 milligrams of isoflavens.

Carbohydrate Content
Carbohydrate removal during processing increases the protein content of soy protein isolate making it a good choice for low-carbohydrate diets. Carbohydrates provide energy for sports and other forms of exercise, which makes them an important part of a healthy diet. When using a soy protein supplement, add carbohydrate-containing foods, such as fruits, vegetables and whole grains.

Fiber and Fat Content
Protein supplements, including soy protein isolate, do not contain fiber unless the food manufacturer adds it during processing. Because fiber promotes feelings of satiety, soy protein isolate without fiber may not leave you feeling full, which could limit its effectiveness in weight loss plans. Soy protein isolate contains 1.5 grams of fat per serving with no saturated fats. Too much saturated fat may increase your risk of heart disease.
