Research has shown that eating grapes is good for the health of the brain, heart, skin, and colon among the large intestine.

A research team from the Department of Pharmacy at Western New England University in the UK revealed that this was the result of investigating the potential of grapes over a total of 8 weeks in 29 healthy men and women.

The research team asked 29 healthy, food-loving men (24 to 55 years old) and women (29 to 53 years old) to eat a restricted diet (day 15) for 2 weeks, including grapes (3 servings a day) for 2 weeks. They were instructed to eat a restricted diet (day 30) and a restricted diet (day 60) that did not contain grapes for 4 weeks. The research team evaluated the composition of the participants’ gut microbiome and urinary glucose metabolites at each stage. Three servings of grapes a day equals 2.25 cups.

After consuming grapes for two weeks, participants showed lower levels of the enzyme Holdemania spp. and higher levels of the Streptococcus thermophiles. Levels of 2′-deoxyribonucleic acid, glutaconic acid, and 3-hydroxyphenylacetic acid also increased. The taxonomic abundance of these enzymes changed and showed distinct microbial distributions. Thermophilic bacteria are bacteria that actively proliferate at high temperatures (above 55 ° C) and are also called thermophilic (heat-loving) microorganisms.

Professor John Pejuto, lead author of the study, said, “The gut microbiome communicates with all organs and is called the ‘gut-organ axis’.” “We found that grapes actively influence the gut microbiome and subtly alter the gut microbiome and the chemicals it produces by altering a complex network of interactions,” he added. In particular, it was analyzed that grapes can improve the health of the heart, colon, brain, and skin.

The results of this study (Influence of grape consumption on the human microbiome) were published in the ‘Human Microbiome Special’ of ≪Scientific Reports≫, the sister journal of Nature, an international academic journal.

◇What ingredients in grapes keep you healthy?= The flavonoid component of grapes prevents blood clots (blood cakes) from being created that interfere with blood circulation. It helps prevent heart disease, stroke, and arteriosclerosis. There are many unsaturated fatty acids that are good for health, so bad cholesterol (LDL cholesterol) is sent out of the body. The resveratrol component of grapes washes cholesterol accumulated in the blood vessels. In addition, anthocyanin, an antioxidant, reduces oxidation in the body and slows down damage and aging. Good for preventing prostate cancer. Resveratrol also helps prevent cancer. Grapes can be eaten with the skin on if washed thoroughly in water. Grapes have a low glycemic index (43-53), so even diabetics can enjoy them. However, it is advisable to be careful not to consume too much.
