Watermelon

Green: Usually a good choice

Watermelon is a water-rich fruit with a soft texture and relatively low calorie density. A moderate bowl can add both fluid and carbohydrate when a heavy snack sounds unappealing.

Why it received this rating

The green rating applies to fresh watermelon in a normal serving. One cup provides mostly water plus about 11 grams of carbohydrate and very little fat, making it different from juice, candy, or syrup-packed fruit.

Portion and preparation guidance

Start with about 1 cup diced. Eat it slowly, and pair it with yogurt, cottage cheese, or another protein if you need a more complete snack.

Symptoms or considerations

Because watermelon is mostly water, a very large bowl can create a lot of stomach volume quickly. If that feels uncomfortable, reduce the portion rather than eliminating the fruit.

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.
