![]() Other important antioxidants in this fruit are resveratrol and quercetin, which may protect against heart disease, high blood sugar levels, and cancer ( 14, 16). Human and animal studies indicate that anthocyanins may help prevent or treat brain and heart diseases ( 14, 15). Some grape varieties contain a higher content of anthocyanins, a class of flavonoids that give these fruits orange, red, blue, pink, and purple colors. ![]() Interestingly enough, these beneficial compounds remain present even after fermentation, which is why wine is also an antioxidant source ( 14, 15). However, multiple factors may affect their concentration, including grape variety, maturity, post-harvest storage, and environmental factors ( 14). The highest concentration of antioxidants is found in the skin and seeds. Grapes are rich in several powerful antioxidants. Oxidative stress is associated with several chronic health conditions, including diabetes, cancer, and heart disease ( 13). SummaryĬompounds in grapes may protect against heart disease by lowering blood pressure and cholesterol levels.Īntioxidants are compounds that help repair the damage to your cells caused by free radicals - harmful molecules that cause oxidative stress. ![]() However, white grapes didn’t have the same effect ( 11).Īdditionally, diets high in resveratrol - an antioxidant in grapes - such as the Mediterranean diet have been shown to decrease cholesterol levels ( 12). In an 8-week study in 69 people with high cholesterol, eating 3 cups (500 grams) of red grapes per day helped lower total and LDL (bad) cholesterol levels. May help reduce cholesterolĬompounds found in grapes may help protect against high cholesterol levels by decreasing cholesterol absorption ( 10). Researchers advised sticking to the current daily intake recommendation of 4.7 grams ( 9). However, a review of 32 studies determined that potassium intakes that are both too low and too high may lead to high blood pressure. It may also help excrete sodium and prevent the narrowing of arteries and veins that would otherwise increase blood pressure ( 8). This mineral is necessary for maintaining healthy blood pressure levels ( 1, 7).Įvidence shows that potassium helps lower blood pressure primarily by helping dilate your arteries and veins. One cup (151 grams) of grapes contains 6% of the DV for potassium. Grapes may boost heart health in several ways. Grapes contain many important vitamins and minerals, including copper and vitamins B and K. Both thiamine and riboflavin are needed for growth and development, while B6 is mainly required for protein metabolism ( 4, 5, 6). Grapes also provide good amounts of B vitamins like thiamine, riboflavin, and B6. Copper is an essential mineral involved in energy production, while vitamin K is vital for blood clotting and healthy bones ( 2, 3). Just 1 cup (151 grams) of red or green grapes provides ( 1):Īs you can see, grapes are a rich source of copper and vitamin K. This makes hedging systems highly advantageous for those who participate.Grapes are high in several important nutrients. If it was possible to extend the database further back across the last 10 years, basis market information and insights, this volatility number would be higher still for this juice. Using all the weekly results since The Juicehedge Index™ began the historical volatility based on the week on week data for the white grape juice has been:Īnnual Volatility – European White Grape Concentrate : 38% These factors in combination with others result in white grape juice prices being volatile. ![]() Separately the global apple juice price can have an impact on demand as some recipes containing a number of different fruits can be interchangeable for their apple or white grape juice quotient parts. In addition the production of juice is effected by the availability of fruit for wine applications. Spring frosts and early autumn periods of prolonged hot dry weather can have quite an impact on fruit and therefore juice production. White Grape Juice production is exposed to varying crop agri-economical conditions, climatic changes and weather patterns. Due to liquidity just the European origin is used for the Hedging mechanism. Both the European and the South American origins are the references for The Juicehedge Index™. The major two regions for production and export for fruit juice applications are Europe (Italy and Spain) and South America (Argentina and Chile). With a global demand varying from 200-300,000 metric tonnes 65 brix per annum White Grape Juice is a significantly consumed fruit juice either on its own or in recipes combined with other fruit juices. ![]()
