Watermelon

Green: Usually a good choice

Generally a good choice when watermelon is prepared simply and eaten in a comfortable portion.

Why it received this rating

Watermelon provides water, vitamins, and fiber in a whole-food form. It is generally more filling and less sugar-concentrated than juice or dried fruit.

Portion and preparation guidance

A cup of cold diced watermelon doubles as food and fluid, which makes it a favorite on hot or low-appetite days.

Symptoms or considerations

It is over 90% water, so big servings can create liquid-volume fullness or sloshing discomfort, and it is a high-FODMAP fruit that gives some people gas or bloating. Moderate portions rarely cause trouble.

Individual tolerance varies. This rating is general educational guidance, not a statement that this food is the right choice for your personal medical needs. Follow advice from your prescriber or registered dietitian.
