Tomatoes are also a good source of vitamin A, which is essential for your vision, skin, and mucous membranes. Vitamin A also helps your body fight infections and inflammation. One tomato slice provides about 4% of the DV of vitamin A.
Potassium
Tomatoes contain potassium, which is a mineral that helps regulate your blood pressure, fluid balance, nerve impulses, and muscle contractions. Potassium also helps prevent kidney stones and osteoporosis. One tomato slice provides about 2% of the DV of potassium.
Folate
Tomatoes provide folate, which is a B vitamin that is involved in DNA synthesis, cell division, and red blood cell production. Folate is especially important for pregnant women, as it helps prevent neural tube defects in the developing fetus. One tomato slice provides about 1% of the DV of folate.
Lycopene

What are the Health Benefits of Tomatoes?
Tomatoes are not only nutritious but also beneficial for your health. They can help you prevent or manage various conditions and diseases. Here are some of the health benefits of tomatoes:
- Tomatoes can help you lose weight. Tomatoes are low in calories, but high in water and fiber. This means that they can fill you up without adding too many calories to your diet. Tomatoes also have a low glycemic index, which means that they do not cause a rapid spike in your blood sugar levels.
- Tomatoes can improve your skin. Tomatoes are rich in vitamin C and lycopene, which can help your skin look younger and healthier. Vitamin C can boost your collagen production, which can reduce wrinkles and sagging.
- Tomatoes can lower your cholesterol. Tomatoes contain a compound called pectin, which is a type of soluble fiber that can bind to cholesterol in your digestive tract and prevent it from being absorbed into your bloodstream. This can help lower your total and LDL (bad) cholesterol levels, which can reduce your risk of heart disease and stroke.
- Tomatoes can prevent urinary tract infections. Tomatoes have a high water content, which can help flush out bacteria and toxins from your urinary tract. Tomatoes also have a low pH, which can make your urine more acidic and inhibit the growth of harmful bacteria. This can help prevent or treat urinary tract infections, such as cystitis and pyelonephritis.
- Tomatoes can boost your mood. Tomatoes contain a substance called tyramine, which is a precursor of dopamine, a neurotransmitter that is responsible for your feelings of pleasure, motivation, and reward.
