Tomato

Tomato is a juicy fruit commonly treated as a vegetable, rich in vitamin C, potassium, vitamin K and folate. It provides antioxidants—especially lycopene—that support heart health, lower blood pressure, and may reduce certain cancer risks. Tomatoes aid skin and eye health, boost immunity, improve digestion due to fiber, and are low-calorie and hydrating. Cooking increases lycopene absorption.

Botanically, a tomato is a fruit — more specifically a berry — because it develops from the ovary of a flower and contains seeds. Culinary practice treats tomatoes as vegetables because they’re used in savory dishes and salads rather than desserts. Nutritionally, tomatoes provide vitamins, minerals, fiber, and antioxidants, fitting both fruit and vegetable roles in a healthy diet.

A tomato is the edible, often red fruit of the plant Solanum lycopersicum, a member of the nightshade family. Low in calories and high in water, vitamins C and A, potassium, fiber and the antioxidant lycopene, tomatoes support heart health and may reduce certain cancer risks. Consumed raw or cooked in salads, sauces and juices, they can trigger reflux or sensitivities in some people.

Raw tomatoes are nutritious and good for most people. They’re low in calories, high in water, fiber, vitamin C, potassium, folate and antioxidants like lycopene, which supports heart health and may lower certain cancer risks. Lycopene is more bioavailable when cooked with fat, but raw tomatoes still offer benefits. Some people may experience acid reflux or sensitivity; wash them well to reduce contaminants.

You can eat tomatoes daily as part of a balanced diet. They’re low-calorie and rich in vitamins C and A, potassium, and lycopene—an antioxidant linked to heart and prostate health. Cooking increases lycopene absorption. Avoid excessive intake if you have acid reflux, a tomato allergy, or advanced kidney disease (high potassium). Maintain variety and consult your clinician for personal advice.

Fresh tomatoes are low in natural sugars: about 2.6–3 g of sugar per 100 g. A medium tomato (~120–125 g) contains roughly 3–4 g of sugar. Cherry tomatoes may be slightly sweeter but remain low—around 3–4 g per 100 g. These sugars are naturally occurring and come with fiber, vitamins, and antioxidants, making tomatoes a nutrient-dense, low-sugar choice.
