Why they matter

  • Lower risk of heart disease, stroke, cancer and early death. In a large analysis, risk kept falling up to about 800 g a day, or 10 portions1.
  • Fibre, potassium, folate and vitamins C and A.
  • Volume without many calories: the secret weapon when you're cutting.

Calories in common fruit and vegetables

Values from USDA FoodData Central3. Filling half your plate with vegetables lets you eat the same volume of food for far fewer calories, which is how you stay full in a deficit. See Cutting without losing muscle.

Common myths

MythFrozen vegetables are less nutritious than fresh.

FactFrozen produce is picked and frozen quickly, and in testing its vitamin content matched or beat fresh produce that had been stored for a few days4.

MythFruit is too high in sugar.

FactThe sugar inside whole fruit isn't a free sugar, and fruit comes with fibre and water that fill you up. It's juice and smoothies to keep to 150 ml a day.

MythPotatoes count as one of your 5 a day.

FactThey're a starchy food, like bread and rice. Sweet potatoes, parsnips and swede do count.
