Effect of increasing fruit and vegetable intake by dietary intervention on nutritional biomarkers and attitudes to dietary change: a randomised trial

Randomized Controlled Trial

Human

The study found that eating more fruits and veggies for 12 weeks didn’t improve heart or blood vessel health markers like blood pressure or cholesterol, even though it boosted some vitamins — so the claim that it had no effect is correct.

When people who don't eat much fruit or veggies start eating about 8 servings a day for 3 months, the level of vitamin C in their blood goes up by 35%, meaning their body gets more of this important nutrient.

Eating more fruits and veggies for 3 months raises the level of folate (a B vitamin) in the blood by 15% in people who used to eat very little of them, helping their body make healthy cells.

Fruits and veggies might help the heart by lowering blood pressure and reducing artery damage, but this study didn’t prove how — it just saw a link.
