What are the health benefits of tomatoes?

Tomatoes are highly beneficial to health, loaded with nutrients like beta-carotene, lycopene, and vitamin C, all of which are powerful antioxidants that help protect cells from damage. Research indicates that the nutrients in tomatoes may reduce the risk of heart disease, neurodegenerative diseases, and type 2 diabetes.

Though often considered a vegetable for culinary purposes due to their taste and use in meals, tomatoes are technically a fruit. This is because they fit the botanical definition of a fruit, being the fleshy part of the plant that surrounds its seeds.

Tomatoes come in various types, such as cherry, grape, and Roma, and in multiple colors, including green, red, and yellow. Let’s delve into the benefits of tomatoes, including their nutritional content.

Aid Immune Function

Tomato juice is rich in vitamin C and beta-carotene, which are antioxidants that support the immune system. Studies show that tomato juice can significantly increase the levels of immune cells, including natural killer cells that combat viruses.

Lower Cancer Risk

Beta-carotene and lycopene in tomatoes have potential anticancer properties. These antioxidants protect against DNA damage in cells, which can lead to cancer, and promote the death of cancer cells. High tomato intake, especially cooked tomatoes, has been linked to a reduced risk of prostate cancer and other cancers, including breast, colorectal, lung, stomach, and upper aerodigestive tract cancers.

Improve Heart Health

A diet rich in tomatoes can lower the risk of heart disease, a leading cause of death. A 2022 review found that high lycopene intake and elevated blood lycopene levels are associated with a 14% reduction in heart disease risk. Studies show that consuming raw tomatoes, tomato sauce, or tomato sauce with olive oil can reduce total cholesterol and triglycerides while increasing HDL cholesterol and anti-inflammatory levels, with the strongest effects observed when combined with olive oil.

Increase Male Fertility

A study published in 2017 found that men with infertility who consumed 7 ounces of tomato juice daily for 12 weeks experienced significant increases in blood lycopene levels and sperm mobility, an indicator of fertility, compared to those taking an antioxidant capsule or placebo.

Prevent Constipation

Tomatoes are an excellent source of water and fiber, both of which help prevent constipation. One whole tomato contains over 4 ounces of water and 1.5 grams of fiber, including both soluble and insoluble fibers, which aid in forming a healthy stool that is easy to pass.

Reduce Type 2 Diabetes Risk

With nearly 15% of adults in the U.S. having diabetes and 38% having prediabetes, tomatoes can play a preventive role. Lycopene and the fiber in tomatoes help protect cells from damage, reduce inflammation, and lower the risk of type 2 diabetes.

Protect Against Metabolic Syndrome

Metabolic syndrome, a cluster of conditions that increase the risk of heart disease, diabetes, and stroke, affects about one in three adults in the U.S. Lycopene levels in the blood may reduce the risk of metabolic syndrome. Drinking tomato juice regularly has been shown to improve cholesterol levels and fasting insulin levels in studies.

Support Brain Health

Alzheimer’s disease, affecting over six million adults aged 65 and older in the U.S., has no cure and worsens over time. Antioxidants in tomatoes, such as lycopene, may slow the decline in cognitive function among older adults. More research is needed, particularly on adults aged 60-65, to fully understand these protective benefits.

Enhance Exercise Recovery

The antioxidants in tomatoes may help offset protein damage caused by exercise. Studies have shown that athletes who consume tomato juice post-exercise recover more effectively, with reduced blood markers linked to exercise-induced damage.

Nutritional of Tomatoes

A whole raw tomato provides:

• Calories: 22.5
• Fat: 0.25 grams
• Sodium: 6.25 milligrams
• Carbohydrates: 4.86 grams
• Fiber: 1.5 grams
• Added sugars: 0 grams
• Protein: 1.1 grams

Micronutrients in Tomatoes

Tomatoes are rich in:

• Folate: Important for DNA production, red blood cell formation, and protein metabolism.
• Potassium: Essential for protein building, carbohydrate metabolism, and heart rhythm regulation.
• Vitamin C: Acts as an antioxidant, promotes healing, and aids in iron absorption.
• Vitamin K: Aids in blood clotting and bone health.

Risks of Tomatoes

It’s important to thoroughly wash or cook raw tomatoes to avoid foodborne illnesses like Listeria and Salmonella, especially for vulnerable groups such as young children, the elderly, pregnant women, and those with weakened immune systems. Tomatoes can also aggravate conditions like GERD and chronic migraines in some individuals. Consulting a healthcare provider is recommended if you have concerns.

Tips for Consuming Tomatoes

• Add raw tomatoes to omelets, avocado toast, and salads.
• Use tomato paste, sauce, and salsa in soups, pasta, chili, and tacos.
• Grill or oven-roast tomatoes.
• Drink tomato juice or use it as a base for gazpacho.
• Stuff tomatoes with hummus, olive tapenade, or vinaigrette-dressed greens.

Cooking tomatoes increases their lycopene content, and consuming them with healthy fats like avocado or olive oil enhances lycopene absorption

A Quick Review

Tomatoes are nutrient-dense fruits that support immune function, reduce cancer risk, improve heart health, increase male fertility, prevent constipation, reduce type 2 diabetes risk, protect against metabolic syndrome, support brain health, and enhance exercise recovery. They are rich in antioxidants like lycopene and vitamins C and K
