Some people are so health-conscious that they want to know the nutritional facts of pretty much everything they eat, even vegetables like tomatoes (okay, tomatoes are technically a fruit, but they are generally considered a vegetable). How many carbs are in tomatoes? A 100 grams of red, raw, ripe tomato only has about 3.9 grams of carbs.

The advantages of eating tomatoes are many. Tomatoes have their origin in South America, but they are popular around the world, mostly as an ingredient for sauces, salads, and even drinks.

What Is So Good About Tomatoes?

Most of the health benefits associated with tomatoes are derived from the fact that they are a huge source of an antioxidant known as lycopene. The health benefits of lycopene include reducing the risk of cancer and heart disease.

But tomatoes are also rich in other dietary sources that include potassium, vitamin C, vitamin K, and folate.

I’m definitely looking forward to the day when I stop working – if I ever stop working. I like the idea of keeling over in my tomato vines in Sardinia or northern Italy. – Anthony Bourdain

Let us now look at who all those dietary sources are so positive.

Potassium is essential for many body functions. It is, in fact, estimated that the human body needs a daily intake of a minimum of 100 milligrams of potassium in order to carry out key health processes.

The benefits of potassium intake include reducing mortality by reducing the risk of stroke, lowering blood pressure, and reducing the risk of kidney stones forming.

Vitamin C, or L-ascorbic acid, is an important antioxidant for the human body. One of its most important benefits is aiding wound healing by creating connective tissue. Vitamin C can be taken as a man-made supplement, but it is also available in many foods, most notably tomatoes and citric fruits.

Vitamin K is a nutrient that has many essential health benefits including reducing blood clotting or improving bone metabolism. Most vegetables are rich in vitamin K so a deficiency in this essential vitamin is rare unless you only eat ultra-processed foods. If that is the case, eating plenty of tomatoes is a great way to counter that. Vitamin K prevents excessive bleeding, weak bones, or decaying tooth. Other foods rich in vitamin K are any green vegetables with leaves, spring onion, brussels sprouts, broccoli, cabbage, prunes, cucumbers, and dried basil.

Finally, folate has many benefits, including reducing the risk or cancer, promoting a healthy pregnancy and healthy development of the fetus for pregnant women, helping the brain carry out its functions, fosters positive moods and, thus, may help in the prevention of depression; it also has anti-aging properties; among other benefits.

Human beings have been eating tomatoes for many hundreds of years. The Spanish discovered it when they first came in contact with the Aztec empire in the 16th century in present-day Mexico. As the Spanish colonized other parts of the world, they spread the tomato, which quickly became a staple food, not only across the Americans but also in Europe and in many other parts of the world until they reached their current global popularity.

What Are the Nutrition Facts of Tomatoes?

Tomatoes are mostly made of water. It is estimated that as much as 95% of the content of every single tomato is water. The remainder 5% is mostly fiber and carbohydrates.

Let us look at the different nutrition facts of tomatoes. These are based on 100 grams of red, raw, ripe tomatoes.

For every 100 grams of tomatoes, there are only 18 calories, 95% of water, 0.9 grams of protein, 3.9 grams of carbs, 2.6 grams of sugar, 1.2 grams of fiber, 0.2 grams of fat, 0.03 grams of saturated, 0.03 grams of monosaturated, 0.08 grams of polyunsaturated, and about 0.08 grams of Omega-6.

Although carbs amount to as much as 4% of raw tomatoes, that only translates to less than 5 grams for every 123 grams (the average tomato is around 123 grams). And most of that carbohydrate content (up to close to 70%) is simple sugars such as fructose and glucose.

There’s nothing to worry about because tomatoes will not increase your carbohydrate intake noticeably. However, tomatoes are a great source of fiber. Every average sized tomato has about 1.5 grams of fiber. And, not only that, but most of the fibers in tomatoes (up to 87%) are insoluble. They come in the form of cellulose, lignin, and hemicellulose.

But, as we saw earlier, tomatoes are a good source of many minerals and vitamins.

There are many health benefits to eating tomatoes, from skin health, to cancer and heart disease reduction.

When we talk about heart health, we are referring to not just heart attacks but also strokes. Heart disease is the main cause of death in the world.

Cancer is when abnormal cells grow uncontrolled part but surpasses their normal boundaries in a specific body part and often invades other body parts.

And skin care, particularly sunburns, can be prevented or healed more effectively thanks to the many qualities of tomatoes.
