Product & Plan FAQsSoy, Fiber, Dairy, Whey
- What type of soy is in Medifast?
Medifast uses Supro® brand soy protein, a high-quality complete protein derived from soybeans. Supro® is produced by DuPont's Protein Technologies. DuPont has been conducting soy protein research for more than 30 years.
What are the benefits of soy?- Studies show naturally occurring isoflavones (such as those in Supro® brand soy protein) have increased the mineral content and density of bones, which may protect against the risk of bone fractures and osteoporosis.
- Studies have indicated that a regular intake of soy foods may help to prevent hormone-related cancers such as breast cancer, prostate cancer and colon cancer.
- Soy works to lower LDL cholesterol (bad cholesterol) levels in the blood, and each 1 percent reduction in LDL cholesterol results in a 2–4 percent reduction in heart disease risk.
- Soy reduces triglyceride levels and increases HDL cholesterol levels (good cholesterol), which further reduces the risk of heart disease.
- Soy isoflavones, which are natural estrogen sources, may help reduce menopausal symptoms such as hot flashes or night sweats.
- Soy is a complete protein, providing all of the essential amino acids.
