In the Hay diet principles, why shouldn’t protein and starches be eaten together?
Proteins take longer to digest than starches

- Proteins and starches must be eaten separately (3-4hrs apart)
- Neutral foods (veg, fats, oils) can be eaten with either protein or starch meals
- Sweet fruit (bananas, grapes) can be eaten with starch meals
- Acid fruit (citrus, pineapple, kiwi) can be eaten with protein meals
Why is fruit more rapidly digested than other foods?

Eat fruit away from other foods including veg
Don’t combine acidic fruit with sweet fruit
Always eat melons on their own
