Research consistently shows…
Increasing fruit and vegetable intake improves overall diet quality, and produce-rich patterns are consistently associated with lower cardiovascular disease and mortality. Research consistently supports 'more produce' as one of the safest, highest-value dietary changes.

How to do it
Add at least one extra serving of vegetables or fruit to each meal
This is the evidence-based dose. A shorter session still counts, it just gives partial benefit rather than the full effect.
Common misconceptions
- 'Frozen and canned don't count.' Frozen and no-salt/no-sugar canned produce are nutritious and affordable.
- 'Juice equals whole fruit.' Whole fruit's fiber matters; juice concentrates sugar.
- 'You need exotic superfoods.' Everyday produce delivers the benefit.
What we won't claim
- Do not claim any food, diet, or supplement cures, treats, or prevents any disease
- Do not diagnose nutrient deficiencies or medical conditions
- Do not promise specific weight-loss amounts or timelines
- Do not deliver individualized medical nutrition therapy or replace clinical care
When to seek a professional
- Signs of disordered eating (food/weight preoccupation, restriction, bingeing, purging, compulsive exercise) -> qualified eating-disorder professional
- Diagnosed medical condition (diabetes, chronic kidney disease, heart failure, GI disease) -> registered dietitian or physician
- Pregnancy or breastfeeding -> prenatal provider or registered dietitian
- Unintentional weight loss, difficulty swallowing, or persistent GI symptoms -> medical evaluation
