The benefits of tomato juice

High concentrations of antioxidants

Tomato juice is a concentrated source of powerful antioxidants such as lycopene, a carotenoid hydrocarbon that has been linked to impressive health benefits.

Lycopene protects your cells from the damage of free radicals, thereby reducing oxidative processes in cells. Many studies have shown that drinking tomato juice rich in lycopene has health benefits.

A weapon against constipation

Tomato is rich in dietary fiber, which is essential to fight constipation.

Constipation isn’t something to be taken lightly. In fact, if left untreated, it can become chronic and lead to serious health consequences. A very simple way to fight it is to follow a diet that promotes intestinal transit.

Drinking tomato juice at breakfast is a great way to fight constipation. Tomatoes are rich in fiber and act as a mild laxative. Thus, if you drink it every day, it may help solve this common problem.

Cardiovascular qualities

It’s important to note that tomato is a great ally of heart health. In this regard, it contains powerful antioxidants, such as lycopene and beta-carotene, which help reduce the risk factors for these diseases. For example, blood pressure and high cholesterol or plaque buildup in the arteries (atherosclerosis).

A study of 584 participants found that those who followed diets rich in tomatoes had a significantly lower risk of heart disease compared to those who didn’t.

It helps boost the immune system

Contraindications of tomato juice

The big problem with tomatoes is their acidity, which can cause digestive discomfort.

However, there are a few things to keep in mind before grabbing a glass of tomato juice every morning. Here are some of them:

  • If you suffer from mouth sores, you should avoid tomatoes, as they’re acid. Many people who undergo chemotherapy suffer from the side effect of mucositis, which causes inflammation and sores. Acidic foods such as tomatoes may worsen the pain this condition causes.
  • For this reason, people with digestive alterations should avoid consuming tomatoes. Thus, if you suffer from esophageal reflux, heartburn, stomach ulcers, or underwent digestive surgery, it’s best to avoid consuming them.
  • Due to its potassium content, tomato is also contraindicated in those who should restrict the consumption of this mineral. For example, this is the case of patients with kidney or heart diseases, insulin deficiency, or metabolic acidosis.
