1. Grapefruit

Grapefruit is a cross between a pomelo and an orange and is commonly associated with dieting and weight loss.

Half a grapefruit, or 123 grams (g), contains just 37 calories but provides 51% of the Daily Value (DV) of vitamin C. Red varieties also provide a small amount of vitamin A (3).

Grapefruit also has a low glycemic index (GI), which means it releases sugar into your bloodstream more slowly. A low GI diet may aid weight loss and maintenance, though the evidence is limited (4, 5, 6).

Plus, grapefruit is high in naringenin, a flavonoid with antioxidant and anti-inflammatory properties that may protect against diabetes and heart disease (7).

While grapefruit can be eaten on its own, it also makes a great addition to salads and other dishes.

SUMMARY

Grapefruit is very low in calories and high in vitamin C. It may be a healthy snack before main meals to help reduce your overall food intake.
