How much Fruit and Vegetable Supplements should I take daily?

Introduction

The daily intake of fruit and vegetable supplements is a topic of interest due to its potential impact on health outcomes such as the risk of type 2 diabetes, cancer, and overall mortality. Research has explored the optimal quantity of fruit and vegetable consumption for health benefits.

Key Insights from Research Papers

Recommended Daily Intake: Public health guidelines generally recommend consuming five or more servings of fruit and vegetables daily to potentially reduce health risks .
Impact on Type 2 Diabetes: Consuming three or more servings of fruit or vegetables daily does not show a substantial reduction in the risk of type 2 diabetes, but higher antioxidant intake, particularly vitamin E, is associated with a reduced risk.
Oxidative DNA Damage: A high intake of fruits and vegetables, specifically 600 grams per day, does not significantly affect oxidative DNA damage or repair in healthy nonsmokers.
Health Outcomes: Higher daily fruit intake is associated with better overall health, lower cholesterol, and blood pressure, while higher vegetable intake is linked to a reduced risk of developing high blood pressure.
Practicality and Consumption: Encouraging the consumption of fruit juice is suggested as a practical step towards meeting the 5-a-day target for fruit and vegetable intake, despite concerns about sugar content and lack of fiber.

Conclusion

The synthesis of the research suggests that while the general recommendation is to consume at least five servings of fruit and vegetables per day, the specific health benefits may vary. Higher antioxidant intake, particularly from sources like vitamin E, may reduce the risk of type 2 diabetes. However, consuming 600 grams of fruit and vegetables daily does not appear to influence oxidative DNA damage in healthy individuals. Daily fruit consumption is linked to improved health markers, and fruit juice may offer a practical way to increase fruit and vegetable intake, although it lacks fiber and contains sugar.

Intake of fruit, vegetables, and antioxidants and risk of type 2 diabetes: systematic review and meta-analysis

Consuming three or more daily servings of fruit or vegetables does not significantly reduce the risk of type 2 diabetes, while antioxidant intake is associated with a 13% reduction in the risk.

No effect of 600 grams fruit and vegetables per day on oxidative DNA damage and repair in healthy nonsmokers.

600 grams of fruit and vegetables per day does not significantly affect oxidative DNA damage in healthy nonsmokers, suggesting that inherent antioxidant defense mechanisms are sufficient to protect circulating mononuclear blood cells from reactive oxygen species.
