Despite the stigma surrounding soy among consumers, science continues to show soy is not only safe to consume, but improves health. A new scientific review of 46 studies has helped solidify the role of soy protein in reducing LDL and total cholesterol, both of which are outcomes linked to improved heart health.
Researchers found that consuming soy protein at a dose of ~25 grams per day led to a decrease in LDL cholesterol of 4.76 mg/dL (3-4%) and a decrease in total cholesterol of 6.41 mg/dL over 6 weeks, which could be considered a clinically significant reduction. Around 75% of the studies reviewed showed a positive effect for consuming soy protein, according to the researchers.
This review is important in helping solidify the role of soy protein in heart health and counter the unwarranted negative perception of soy among many consumers.
