When people who don’t eat much fruit or veggies are given them for free every week, they start eating almost 8 servings a day—proving that lack of access is a big reason they don’t eat enough.

Scientific Claim

Providing free fruit and vegetables for 12 weeks increases daily intake to 8.4 portions in healthy adults aged 39–58 with low baseline intake, demonstrating that access and provision can overcome habitual low consumption.

Original Statement

“Intake increased significantly in the intervention group compared to controls, achieving 8.4 portions/day after 12 weeks.”

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 gave people free fruit and veggies for 12 weeks, and they started eating over 8 portions a day—even though they used to eat very little. This shows that just giving them the food, not just telling them to eat more, worked.

Even after eating a lot of fruits and veggies for 3 months, most people go back to eating only a little bit again a year later unless someone keeps giving them the food.

People stop eating lots of fruits and veggies not because they don’t know how to cook them, but because they’re too expensive, hard to buy often, and there’s just too much to eat every day.

When people eat a lot more fruits and fruit juice for 3 months, their sugar intake goes up by 40%, which might be a hidden downside of trying to eat healthier.

Eating more fruits and veggies for 3 months doesn’t lower blood pressure, cholesterol, or sugar levels—or make arteries less stiff—in healthy people who were already eating poorly.
