4. Dairy Products
The relationship between dairy consumption and prostate cancer risk remains a topic of debate in scientific research.
Research Findings
- Some studies suggest that high calcium intake from dairy products may be associated with an increased risk of prostate cancer. However, other research indicates that dairy may have protective effects due to its nutrient profile.
Recommendations
Moderation is key. If you consume dairy, opt for low-fat options and balance your diet with plant-based foods.
5. Soy Products
Soy contains phytoestrogens, which can influence hormone levels in the body.
Potential Benefits
- Some studies suggest that regular consumption of soy products (such as tofu, tempeh, and edamame) may be associated with a lower risk of prostate cancer. The isoflavones in soy may help regulate hormone levels and have antioxidant properties.
6. Green Tea
Green tea is rich in catechins, a type of antioxidant that has garnered attention for its potential cancer-fighting properties.
Research Insights
- Several studies have suggested that green tea consumption may be associated with a reduced risk of prostate cancer. The catechins in green tea may inhibit tumor growth and reduce inflammation.
Dietary Patterns for Prostate Health
