GRAPES

    Grapes come in different colors and shapes. There are red grapes, green grapes, purple grapes, seedless grapes, jelly, jam and grape juice, raisins, ocean currents and raisins, not to mention wine. Today, 72 million tons of grapes are planted around the world each year, mainly for the production of wine. 7.2 trillion gallons of wine are produced annually. Grapes are also a popular snack. The nutrients in grapes have many potential health benefits. They are related to the prevention of cancer, heart disease, high blood pressure and constipation.

Description :
     Grapes are a type of fruit that grows in clusters of 15 to 300 and can be scarlet, black, dark blue, yellow, green, orange, and pink. The "white" grapes are actually green and are evolutionarily derived from purple grapes. Mutations in two regulatory genes in white grapes shut off the production of anthocyanins, which are responsible for the color of purple grapes. Anthocyanins and other pigment chemicals from the larger family of polyphenols in purple grapes are responsible for the different shades of purple in red wines. Grapes are usually ellipsoidal in shape, resembling an elongated spheroid.

Benefits :
Prevent Chronic Diseases :
     Antioxidants are compounds found in plants, for example. They help repair cell damage caused by free radicals, which are harmful molecules that cause oxidative stress. Oxidative stress is linked to several chronic diseases, including diabetes, cancer and heart disease. Grapes contain many powerful

antioxidant compounds. In fact, over 1,600 beneficial plant compounds have been identified in this fruit. The highest concentration of antioxidants is found in the skin and seeds. For this reason, most of the grape research has been done using seed or skin extracts. Red grapes contain a higher amount of antioxidants due to the anthocyanins that give them their color. The antioxidants in grapes remain present even after fermentation, which is why red wine is also rich in these compounds. One of the antioxidants in this fruit is resveratrol, which is classified as a polyphenol. There have been many studies on its properties that show that resveratrol protects against heart disease, lowers blood sugar levels, and protects against the development of cancer. Grapes also contain vitamin C, beta-carotene, quercetin, lutein, lycopene, and ellagic acid, which are also powerful antioxidants.

Protection Against Cancer :
     Grapes contain high levels of beneficial plant compounds that can help protect against certain types of cancer. Resveratrol, one of the compounds found in this fruit, has been well studied for the prevention and treatment of cancer. has been shown to protect against cancer by reducing inflammation, acting as an antioxidant, and blocking the growth and spread of cancer cells throughout the body. However, the unique combination of plant compounds found in grapes may be responsible for their anti-cancer effects. In addition to resveratrol, grapes also contain quercetin, anthocyanins, and catechins - all of which can have beneficial effects on cancer. In test-tube studies, grape extracts have been shown to block the growth and spread of human colon cancer cells. in 30 people over the age of 50 found that consuming 450 grams of grapes a day for two weeks reduced risk markers for colon cancer. Studies have also shown that grape extracts block the growth and spread of breast cancer cells in both laboratory and mouse models. Although research into grapes and human cancer is limited, diets high in antioxidant-rich foods like grapes are associated with a lower risk of cancer.

Help Lower Your Blood Pressure :
     One cup (151 grams) of grapes contains 288 mg of potassium, which is 6% of the RDI. This mineral is essential for the maintenance of normal blood pressure levels. Low potassium intake is associated with an increased risk of high blood pressure, heart disease, and stroke. A study of 12,267 adults found that those who consumed higher levels of potassium over sodium had less chance of dying from heart disease than those who consumed less potassium.

Help Lower Cholesterol :
     Compounds in grapes can help protect against high cholesterol by reducing the absorption of cholesterol. In one study of 69 people with high cholesterol, consuming three cups (500 grams) of red grapes a day for eight weeks showed a reduction in overall levels and "bad" LDL cholesterol. The white grapes did not have the same effect. In addition, resveratrol-rich diets, such as the Mediterranean diet, have also been shown to lower cholesterol.

Protect Yourself From Diabetes :
     Grapes contain 23 grams of sugar per cup (151 grams), which may make you wonder if they're a good choice for people with diabetes. They have a low glycemic index (GI) of 53, which is a measure of how quickly food raises your blood sugar levels. What's more, the compounds found in grapes can even lower blood sugar levels. In a 16-week study involving 38 men, those who took 20 grams of grape extract daily experienced lowered blood sugar levels compared to the control group. In addition, resveratrol has been shown to increase insulin sensitivity, which can improve the body's ability to use glucose and thus lower blood sugar levels. Resveratrol also increases the number of glucose receptors on cell membranes, which may have a beneficial effect on blood sugar levels. Managing blood sugar levels over time is an important factor in reducing the risk of diabetes.

Good For Eye Health :
     The plant chemicals found in grapes can protect against common eye diseases. In one study, mice fed the grape-supplemented diet showed fewer signs of retinal damage and had better retinal function compared to mice that were not fed fruit. A test-tube study found that resveratrol protects the retinal cells in the human eye from ultraviolet A light. This may lower the risk of developing age-related macular degeneration (AMD), a common eye disease. According to a review study, resveratrol may also help protect against glaucoma, cataracts, and diabetic eye disease. In addition, grapes contain the antioxidants lutein and zeaxanthin. Several studies have shown that these compounds help protect your eyes from blue light damage.

Improve Memory, Attention & Mood :
     Consuming grapes can benefit brain health and improve memory. In a 12-week study involving 111 healthy elderly people, 250 mg of a grape supplement daily significantly improved the cognitive test that measures attention, memory and language compared to baseline. Another study in healthy young adults found that drinking about 230 ml of grape juice improved both the speed of memory skills and mood 20 minutes after consumption. Studies in rats showed that resveratrol improved learning, memory, and mood when taken for 4 weeks. In addition, the rat brains showed signs of increased growth and blood flow. Resveratrol may also help protect against Alzheimer's disease, although human studies are needed to confirm this.

Important For Bone Health :

     Grapes contain many of the minerals necessary for bone health, including calcium, magnesium, potassium, phosphorus, manganese, and vitamin K. Although studies in rats have shown that resveratrol improves bone density, these results have not been confirmed in humans. In one study, rats fed freeze-dried grape powder for 8 weeks had better bone absorption and calcium retention compared to rats that did not receive the powder. There is currently a lack of human research into the effects of grapes on bone health.

Slow Down Aging & Promote Longevity :
     Plant compounds found in grapes can affect aging and their age. Resveratrol has been shown to increase the longevity of animals. This mixture stimulates a family of proteins called sirtuins, which are associated with longevity. one gene that resveratrol activates is the SirT1 gene. This is a genetically engineered gene from low-calorie foods, combined with longevity in animal studies. Resveratrol also affects many other genes related to aging and longevity.

Protect Against Some Viruses, Bacteria, and Yeast Infections :
     Many compounds in grapes have been shown to protect and fight viruses that have become infected. Grapes are a good source of vitamin C, well known for its beneficial effects on your system. Grapefruit is shown to protect against influenza virus in test-tube studies. In addition, grapefruit compounds prevent the spread of herpes, chickenpox, and yeast infections in tube-bearing. Resveratrol can also protect against foodborne illness. When a variety of foods are added, it has been shown to inhibit the growth of harmful bacteria, such as E. Coli.
