Soy Protein and Cholesterol
How Much to Eat
If you’re new to eating soy, add it to your diet a little bit at a time. Substitute soy protein for animal protein foods a few times a week. That’s the best way to cut saturated fat and lower your overall risk of disease.
A little goes a long way. Your best diet is one that has a variety of foods, like fruits, vegetables, nuts, seeds, whole grains, and beans. That’s better than a diet that’s too heavy in soy products.
Eating soy in moderation should be fine. But ease into it and see how you do. It's rare, but some people have digestion problems (like stomach pain, loose stools, or diarrhea) when they eat soy. Others are allergic to soy.
Also, "some people have concerns that too much soy can have negative hormonal effects, particularly on men,” Beckerman says. There is some controversy about this. Talk with your doctor or a nutritionist about how much soy you should include in your diet.
