Tomato: benefits and harms

Tomatoes are one of the most common vegetables and regular guests of summer tables. They are loved all over the world, and Italians cannot imagine their life without juicy tomato paste. Let’s take a closer look at red tomatoes, find out their benefits and harms to the human body and figure out how to choose them.

The nutritional value
The energy value of a tomato is only 24 kcal per 100 g. This makes them a real godsend for those who are watching their weight.
The reason for the low-calorie content of tomatoes is their high water content: about 92%. The rest of the composition:

  • carbohydrates – 3.8%;
  • dietary fiber – 1.4%;
  • proteins – 1.1%;
  • fat – 0.2%.

The main constituent of a tomato is lycopene. It is he who determines the scarlet color of the fruit. Lycopene is a powerful antioxidant that slows down oxidative processes in the human body. It also protects the DNA structure, thanks to which it can resist cancer.
Tomatoes are rich in vitamins and minerals:

  • Vitamin C – 28% Daily Value per 100g Strengthens the immune system, increases efficiency, normalizes cholesterol levels, and removes toxins from the body.
  • Vitamin A (15%). Improves metabolism and helps synthesize proteins that are needed for normal muscle growth and development. Plays an important role in the stable functioning of the eyes.
  • Potassium (12%). Normalizes the body’s water balance and improves blood quality. Regulates the digestive tract.
  • Cobalt (60%). Responsible for the stable functioning of the nervous system and liver, and also promotes hematopoiesis. Due to the lack, acobaltosis develops, which leads to loss of appetite and sharp weight loss, as well as to a decrease in the level of hemoglobin in the blood.

Also, the tomato contains vitamins of class B, E, H and PP, copper, molybdenum, and other useful substances.

The benefits of tomato for the body

  • Lycopene slows down the development of atherosclerosis and prevents eye diseases.
  • Due to their high fiber content, tomatoes facilitate and accelerate the absorption of food, which has a positive effect on the digestive tract.
  • Tomatoes normalize stomach acidity and increase intestinal motility, preventing bloating and constipation.
  • Tomatoes contain a lot of water, which helps to thin the blood. This prevents the development of varicose veins, angina pectoris, thrombosis, and other similar diseases.
  • Cobalt in tomatoes regulates the emotional background, improves the state of the nervous system, and helps to cope with stress.
  • Fresh fruits strengthen the immune system and fight viruses, and also remove toxins from the body.
  • Tomatoes have a mild diuretic effect and relieve slight swelling.
  • Tomatoes cleanse the liver and help fight hepatitis.

The benefits of a tomato for the female body
Fresh tomatoes are great for dieting. Fiber speeds up the metabolism and improves the functioning of the digestive tract, so you can quickly lose weight. A glass of freshly squeezed juice reduces appetite and prevents overeating.

Ointments and creams for acne, rashes, dermatitis, and eczema are made from unripe tomatoes. Such funds remove scars, scars, and other consequences of these diseases. They also tighten and rejuvenate the skin.

The benefits of a tomato for the male body
Tomatoes strengthen bones and nourish muscles, which is very important for strenuous physical activity.
Tomatoes improve the functioning of the sex glands and increase the sexual energy of a man, as well as prevent the development of prostatitis.

Who is not allowed to eat

  • People with cholelithiasis and kidney problems. Due to the diuretic effect, stones can move and clog the urinary system.
  • Patients with joint diseases. Tomatoes contain oxalic acid, which can cause salt build-up and increase joint pain.
  • As we said, tomatoes increase the acidity of the stomach. If you have pancreatic inflammation or other acute gastrointestinal disease, tomatoes will only make your condition worse.

Harm to the body
The main disadvantage of tomatoes is oxalic acid, which disrupts water-salt metabolism in the body. This leads to the deposition of salts and contributes to the formation of kidney stones. If you have a predisposition to diseases of the joints and urinary system, limit the use of fresh fruits and avoid salted tomatoes, ketchup, and pasta.

How to choose
Fresh tomatoes

  • The peel should be firm and complete. If there are cracks or dry areas, tomatoes can quickly deteriorate.
  • Make sure the color is evenly distributed. Greenish areas indicate that the fruit is not fully ripe.
  • Make sure the leaves are green and fresh when buying fruit on the branches. If they are already dry, then the fruit is likely to ripen after the break.


  • The composition should not contain salt.
  • Do not buy juice with very bright and saturated color: most likely, a lot of dyes were added there.
  • In terms of consistency, tomato juice should resemble water. If it is viscous, the manufacturer has used starch or other thickeners.

Pasta and ketchup

  • Examine the ingredients and make sure there are no dyes, preservatives, or other additives.
  • Unlike juice, a good paste has a bright, rich color. Too dark a paste probably contains puree from other vegetables. If the ketchup is light, it must have been diluted with water.
  • Pay attention to the price: if a kilogram of pasta is much cheaper than 2-3 kg of tomatoes, then most likely it was not made from fresh fruits.

Salted tomatoes

  • The composition should include only tomatoes, vinegar, water, salt, and sugar.
  • Despite the vinegar content, pickled tomatoes should not have a strong odor.

  1. I have a little arthritis so tomatoes may not be good for that, but they have so many good things in them like vitamins. So I’m not sure what to do. I do eat them a little, but not too much. Any advice?

    1. Oh, need to be careful with tomato, it`s acid might do a hard. Eat it not so often or do not eat at all. With exacerbation and chronic deseases it is prohibited.

  2. I absolutely love raw tomatoes (not cooked though). That said, I have been told by certain Dr.’s on YouTube (Dr. Google) that it is inadvisable to eat the seeds or most of the inner portions of the tomato as it is a member of the nightshade family and as such (some?) cooks often remove the interior before adding to recipes. Is this your understanding as well? So far, I have refused to deign to their advice.

      1. Well, not really, all seeds consist of a healthy or not healthy substances, I do get read of seed from bell pepper, paprika, just the rest I got used to from childhood eat just the way it is, eggplant I do not eat often, because it is pretty heavy for my stomach. Green potatoes I never eat, when I was a child, my mom was telling me that it is bad. I think, the sujestion here, do not eat seeds a lot, every seed has poison. I have heard some doctor was saying that it is healthy to eat a few apple seeds per day, but it is toxic, better never eat it.
