Grapes properties and health benefits.
Grapes are a type of berry climbing plant that is rich in many nutrients.
Including vitamin C and vitamin K. They also contain flavonoids, which have antioxidant properties. Many people believe that grapes have the ability to reduce blood fat levels, reduce the risk of coronary heart disease, and grape leaves may help reduce inflammation, help heal tissue, stop bleeding, and help relieve diarrhea. But how much medical evidence is there to confirm the properties, benefits, and safety of eating grapes, including grape seed extract, which plays a role or helps in treating these diseases?
Grapes and their health benefits
Poor blood circulation, which causes leg swelling and varicose veins. Many experts believe that blood vessel or vein disease may be the result of free radicals. Grapes are a fruit rich in antioxidants, which may help or benefit such symptoms. Therefore, a study was conducted to give women who work and have to sit for a long time to take grape seed extract or a placebo for a single dose and for 14 days, sitting for 6 hours. It was found that taking grape seed extract, which contains proanthocyanidin, an active substance, was a factor that significantly inhibited leg swelling in healthy women who had to sit for a long time.
Nourishes the eyes: Grapes contain สมัครสมาชิก UFABET วันนี้ รับเครดิตฟรีทุกวัน various nutrients and vitamins, including antioxidants that are beneficial to the eyes. There is an experiment on the use of grape seed extract to treat ganglion cells of the retina or retina (Retina Ganglion Cell). It was found that the rate of nerve cell death was reduced. This is a result of grape seed extract inhibiting cell damage from free radicals. However, since it is still just an experiment in the laboratory. Further studies are needed to confirm the effectiveness of grapes more clearly.
Possible grapevine treatment, but lack of evidence to support it
Exercise performance Athletes or those who exercise heavily produce compounds with excessive oxygen in the molecule (Reactive Oxygen Species).
Which can damage the body’s cells, including higher levels of antioxidants but not enough to inhibit the creation of free radicals. Therefore, there is research on grape extract that may help increase antioxidant levels and exercise performance in male athletes. By randomly assigning 20 handball, basketball, runners and volleyball players who are in the middle of a sports competition to take a supplement containing 400 milligrams of grape extract per day for 30 days and another group to take a placebo. Blood and urine tests were conducted before. After the experiment for 1 month. It was found that the antioxidant levels and exercise performance of the handball players increased. Which may be due to the properties of grape extract. And this research also supports further studies to confirm the effectiveness and mechanism of action of grape extract in athletes.
Cardiovascular disease is one of the most prevalent diseases in the past century.
Therefore, proactive management is need to cope with it. It is recommend to eat vegetables or fruits, including grapes, to reduce the risk of developing the disease. Epidemiological research has shown. That consuming wine or grape products, as well as foods containing polyphenols, is associat with a reduc risk of developing cardiovascular disease.
Experiments have shown that polyphenols in grapes reduce atherosclerosis through various mechanisms, including inhibiting the oxidation of bad cholesterol, having a positive effect on redox reactions in cells or controlling the reaction of free radicals in the body to balance, improving the function of coronary arteries, reducing blood pressure levels, inhibiting platelet aggregation, reducing inflammation, and stimulating protein function to prevent cell deterioration. Many human studies support the efficacy of grapes mentioned above. But further studies are need. Before experiments can confirm the efficacy and determine the guidelines for grape consumption. However, the current data supports and suggests that eating grapes, as well as other fruits and vegetables, can reduce the risk of developing cardiovascular disease.
High cholesterol Consuming grapes. A fruit rich in flavonoids, has an antioxidant effect. Inhibits platelet function, and reduces blood clot formation.
Which is beneficial for people with cardiovascular disease and people with high blood cholesterol levels. Therefore, an experiment was conduct on the effectiveness of consuming red grape juice on body fat levels. 26 healthy male volunteers, who did not smoke or take medications, aged 25-60, consumed 150 ml of red grape juice twice a day for 1 month. Their blood fat levels.
Hypertension is one of the risks of cardiovascular disease. There is now evidence of the effects of grapes on blood pressure, which led to an analysis of the literature and research on the effectiveness of polyphenols found in grapes. From a total of 10 studies. When compared to taking blood pressure-lowering drugs. However, future studies need to develop better experimental designs and be larger in size to confirm the results of the experiments more effectively.
Metabolic syndrome is a syndrome.
That includes many diseases such as hypertension, diabetes, hyperlipidemia, cerebrovascular disease, and cardiovascular disease. Studies have shown evidence of eating foods rich in polyphenols, which have antioxidant properties, found in grapes, especially grape seed extract, as well as various vegetables and fruits. The benefits of polyphenols have report to be able to inhibit the risk of metabolic syndrome. The results of the study found that polyphenols in grapes have an effect on blood pressure, blood sugar and blood lipid levels, and are also beneficial to liver and heart function significantly. However, more studies need to confirm the efficacy of polyphenols in grapes.
Fatty liver disease Since the treatment methods for fatty liver disease still quite limited.
While the antioxidant properties of vegetables and fruits are increasing, there is a research on the use of grape seed extract to help improve liver function in patients with fatty liver disease. The sample group of 15 people was randomly assign to take a supplement containing grape seed extract or vitamin C in the amount of 1,000 milligrams every 12 hours for 3 months. The liver function of the sample group was examin. Before the experiment and repeated at the 1st, 2nd and 3rd months. It was found. That grape seed extract may help improve the symptoms of patients with fatty liver disease. If the results are follow up for a long time.
