Soy lowers cholesterol level but not as much as the three plant foods mentioned above. However, it is one of the most common and versatile ingredients used in the kitchen. Soy is also used as a substitute for meat products, and these meat products are the common culprit for increased cholesterol in the blood. Replacing some meat recipes with soy can make a significant change in one’s health. Soy milk is also delicious and will make any low-cholesterol recipe tastier and less bland.
