1. Grapes helps to improve the health of the eyes
According to research, consuming grapes could help in protecting eye health. The study revealed that a grape supplemented diet countered oxidative stress damage and preserved retinal function and structure in a laboratory model of retinal degeneration.
Grape components that help in the promotion of antioxidant activity are believed to be responsible for these health benefits, consistent with prior research that suggests compounds derived from grapes are biologically active in the retina.
2. Grapes may help to prevent Alzheimer’s disease
Polyphenols in grapes help promote anti-inflammatory and antioxidant activities. Studies indicate that grapes could help support the health of the brain by functioning in a variety of ways, from the reduction of oxidative stress in the brain to the promotion of healthy brain blood flow to maintaining levels of a chemical in the brain that promotes memory to the exertion of anti-inflammatory effects.
In a study of individuals suffering from early memory decline, the consumption of grapes twice daily for 6 months protected against considerable metabolic decline in brain areas related to Alzheimer’s disease. Low metabolic activity in these brain areas is a characteristic of early-stage Alzheimer’s. The results of the study revealed that a diet enriched with grapes helped protect against metabolic activity decline.
3. Grapes may help to improve symptoms of knee osteoarthritis
The results of a study indicate that regular consumption of grapes could help to alleviate pain related to symptomatic knee osteoarthritis, as well as improve flexibility of the joint and overall mobility. The potential benefits are attributed to the polyphenols that are found in grapes.
4. Grapes may help to fight against upper respiratory tract inflammation
According to a study, the resveratrol found in grapes can help in controlling the inflammation caused by a bacterial pathogen that is associated with upper respiratory tract inflammatory diseases like chronic obstructive pulmonary diseases (COPD), asthma, and middle ear infection (otitis media).
It was discovered that resveratrol inhibits an important bacterial pathogen leading to COPD and otitis media by upregulating or increasing the production of a negative regulator known as MyD88 short.
Resveratrol is a member of a group of compounds known as polyphenols that are believed to act like antioxidants protecting the body against damage. It’s long been regarded as a therapeutic agent for some diseases, such as inflammatory diseases. Resveratrol was found to be effective against inflammation due to a serious respiratory pathogen known as nontypeable Haemophilus influenzae (NTHi).
An appropriate level of inflammation in the body can be beneficial for defense against bacterial infection, but uncontrolled inflammation can result in inflammatory diseases.
5. Grapes helps protect against UV damage to skin
A study has revealed that grape consumption helps protect against skin damage from exposure to ultraviolet (UV) light. Individuals showed increased sunburn resistance and a decrease in UV damage markers at the cellular level. Natural components within grapes called polyphenols are believed to be responsible for these benefits.
Grapes may behave as an edible sunscreen, which could provide an additional layer of protection together with topical sunscreen products.
