Garlic extract prevents heart disease
evidence
The Claim
Many people believe that taking garlic extract can significantly reduce the risk of developing heart disease. This claim is based on the idea that garlic has anti-inflammatory and cholesterol-lowering properties.
Origin
This myth originated from early observational studies and traditional medicine practices that link garlic consumption with heart health.
What Science Says
Research, including meta-analyses, indicates that while garlic can have a modest effect on lowering blood pressure and cholesterol levels, the effect sizes are generally small. Randomized controlled trials (RCTs) have shown mixed results, with some indicating minimal impact on heart disease risk factors. Therefore, while there may be some cardiovascular benefits, they are not substantial enough to prevent heart disease on their own.
Verdict
Partially True
