Grape Health Benefits – What are its properties?

The grape is a fruit that represents more than a great global horticulture, it has ancient historical connections with the development of human culture. The main product, wine, was, for many years, considered divine.

he so-called phytochemicals, present in fruits and vegetables, can play an important role in controlling the risk of chronic diseases. Grapes, one of the most popular and widely consumed fruits in the world, are rich in phytochemicals.

Among the most important phytochemicals, it is possible to mention phenolic compounds, due to their enormous health benefits, including protection against some diseases.

Grape is an easily available food containing significant amount of varied phenolic compounds such as stilbenes, flavonols and anthocyanins. They are known to be highly effective against cardiovascular disease. The most famous of them, resveratrol is one of the representatives of the stilbene class and which became more popular after the discovery of its anticancer potential.


The phytochemical composition of grapes varies greatly between different varieties. The vines belong to the plant genus called Vitis L., which has, in total, about 60 species of grapes. More than 70% of the species are native to North America, where two main grape species are grown: Vitis labrusca and Vitis rotundifolia . The first was cultivated with several cultivars of another species, Vitis vinifera, to create hybrid grapes suitable for the production of juice, jelly, fresh fruit and wine.

The main types of grape most consumed in Brazil are:

  • Italian grape : variety classified as a fine table grape, one of the best for consumption “in natura”. The bunches are big and have a green color.
  • Chardonnay grape : and considered “the queen of white grapes”, being widely used in the production of white wine.
  • Ruby grape : of Asian origin made from a mutation of the Italian grape, it has a firm texture and wine color. It is characterized by having large concentrations of water and mineral salts.
  • Thompson grape : it is the most consumed table grape in the world. The bunches are yellowish in color, small in size and used to produce raisins. Does not contain seeds.
  • Grape Merlot : of French origin, its main characteristic is its quality, with a more citrus and fresh flavor, offering several nutrients and antioxidants.
  • Cabernet Sauvignon grape :  also of French origin, the grape has several properties, being rich in vitamin C and proteins, carbohydrates and flavonoids.


Resveratrol is widely studied for its nutritional and medicinal value. Scientific researches have also shown that it is able to induce resistance in plants against microbial infections and increase the life expectancy of different organisms.

The demand for resveratrol is increasing due to its promising potential to treat cardiovascular disease and its anti-cancer and anti-aging effects. To meet this demand, resveratrol is currently marketed as a food supplement, in the form of capsules, powders and pills.

Most foods rich in resveratrol originate from plant sources. In addition to resveratrol, plants also provide other phytonutrients that also contribute to health.

Few plant species, including grapes, peanuts, pine and tomatoes, produce resveratrol. However, the grape is the fruit that contains the highest amounts compared to all other natural sources. Almost every part of the grape contains resveratrol, including the stem, leaf, and root, with the skin being the most important source of this component in red wine and whole grape juice .


1. Grape Health Benefits – Grapes are a good source of phenolic acids, flavonoids and resveratrol, all of which have been studied to have positive health effects.

2. Benefits of grapes against cardiovascular diseases – Studies have associated the consumption of grapes with a reduction in the risk of developing chronic diseases including certain types of cancer and cardiovascular diseases. Research in vitro and in vivo have shown that grapes have a strong antioxidant activity, inhibiting cancer cell proliferation, while also helping to lower cholesterol.

3. Grape Benefits as Antioxidants – Grapes contain a variety of phytochemicals such as phenolic acids, stilbenes, anthocyanins and proanthocyanidins, all of which are strong antioxidants.

4. Benefits of grapes for age – These phytochemicals are not only antioxidants, anticancers, anti-inflammatory drugs , but they are also cardioprotective, neuroprotective, hepatoprotective and inhibit age-related cognitive decline.

5. Benefits of Grapes Against Chronic Diseases – Many scientific experiments support the ability of grapes to prevent heart disease and certain types of cancer. Due to their flavonoids and stilbenes, there are strong associations between grapes and reduced risk of chronic disease.


  • In a laboratory study, grape seed extract significantly improved the degree of liver fat change in sick patients.
  • In another study, grape seed extract was associated with a reduced risk of cutaneous squamous cell carcinoma, a type of cancer.
  • A survey found that the grape loses weight because it has a low glycemic index. In addition, its phenolics showed potential to decrease hyperglycemia, suggesting that grapes may have benefits for people with type 2 diabetes.


Purple grapes, especially their seeds, have strong antioxidant activity.

The antioxidant effects of phenols in various types of grapes showed that this ability is related to the concentration of phenols in the fruit. The antioxidant activities of purple grapes were attributed to both phenolics and flavonoids.


The green grape is evolutionarily derived from the purple grape. Some mutations in the purple grape turn off the production of anthocyanins, molecules that are responsible for the purple color of the grapes.

These compounds and other polyphenols are characterized by various shades, ranging from purple (almost black) to red.

In addition, sour grapes are considered more nutritious and are able to boost the immune system.


Grapes can offer enormous benefits during pregnancy, for both mother and baby, as they contain components such as:

  • Vitamin A, C and B1
  • beta carotene
  • Phosphor
  • Calcium
  • Iron
  • Magnesium
  • Folic acid
  • Omega 3
  • Fibers

However, pregnant women will only receive the benefits of grapes by consuming them according to the amount suggested by doctors. Keep reading the article as we’ll talk about it later.

The following are the 7 main benefits of grapes in pregnancy:

 1. Improve baby brain development by the presence of folic acid. The most important function of this component is its ability to reduce the risk of birth defects.

2. Formation of bones and teeth by the presence of folic acid and calcium, which optimize the baby’s development and strengthen the mother’s bones.

3. Prevention of anemia. Pregnant women often have anemia in the second trimester. This is because red blood cells share their benefits for both mother and fetus. Anemia can be prevented by pregnant women by consuming red grapes, which are the richest in iron.

4. Improved digestive system. Constipation is a common digestive problem during pregnancy. Grapes help the digestive system to perform well as they contain a high concentration of fiber, and are therefore recommended for this purpose.

5. Detox. The fiber provided by grapes helps to clear toxins from the body.

6. Increased Immune System. Pregnant women are advised to consume grape juice because it has an alkaline streak, which can maintain the immune system and improve kidney performance.

7. Reduce swelling. Grapes contain calcium and magnesium that have been shown to reduce swelling in pregnant women.


As not everything in life is perfect, the grape may not be suitable for certain conditions or cause problems if not consumed in the ideal quantity and form.

See below some harmful effects of the grape:

  • Grapes are hard to digest

Black grapes are quite problematic for pregnant women because their skin is difficult to digest. In addition, their digestive system is very sensitive, and they are advised to avoid this type of grape.

  • High acidity level

Depending on the level of ripeness, grapes can cause heartburn. The high level of acidity can cause vomiting, a recurrent problem in pregnancy. Grapes should be avoided in cases of gastritis problem.

  • High level of resveratrol

That’s right! Although resveratrol has been shown to be highly beneficial to health, its high consumption can trigger hormonal imbalance.

In order to get the absolute benefits of grapes and avoid their dangerous side effects, there are several consumption tips.


  • Consume a maximum of 200g of grapes per day.
  • Peel the grapes before consuming them because the skin of the grapes contains a lot of resveratrol.
  • Consume sour grapes because research shows that they are more nutritious than dark-skinned grapes.
  • Consuming grape juice in the morning provides more energy for the day and prevents fatigue.
  • Consuming grape juice in the morning increases your appetite.
