Though they’re technically a fruit, tomatoes are considered a vegetable due to their savory flavor. Like other non-starchy vegetables, tomatoes are rich in water and low in calories, making them a great choice for people who are trying to lose weight. They are packed with antioxidants, including vitamin C, lycopene, beta-carotene, and quercetin, which help prevent and manage arthritis, skin, hair, and teeth. Tomatoes also provide potassium, a mineral that may help lower blood pressure and boost bone health. In some individuals with migraines, tomatoes are a trigger food and should be avoided. IBS sufferers take note: Some people with IBS are sensitive to raw vegetables and experience discomfort after eating them.
