Is it a Muscadine or a Scuppernong?

“All Scuppernongs are Muscadines, but not all Muscadines are Scuppernongs.”

 

Muscadine is a broad category of grape that includes many varieties of both bronze and black grapes. Scuppernong is one of the bronze varieties included in the muscadine category. Scuppernong is one of the oldest and most popular varieties, so the name is sometimes used to refer to any bronze variety of muscadine. There are now many other varieties of muscadines used in wine production and for fresh eating. So to be correct, it is better to use the term muscadine when uncertain of the variety. Some other popular varieties include:
Bronze: Scuppernong, Carlos, Magnolia, Fry, Triumph
Black: Noble, Nesbitt, Ison, Supreme

Muscadine Wine: An Ingredient in a Healthy Lifestyle

 

Disclaimer:
Wine should be consumed only in moderation; generally no more than one drink per day for women and no more than two drinks per day for men. Please consult your physician over concerns of proper alcohol consumption. Long-term, excessive alcohol consumption can cause serious negative health consequences and even moderate alcohol consumption can have negative health consequences for some people. People with medical and social conditions worsened by alcohol should not consume alcohol at all. Pregnant women should abstain from alcohol consumption. You should not start or increase your alcohol consumption for health reasons.

 

Research on the health effects of resveratrol has not been directly conducted on humans and currently there is no scientifically conclusive evidence as to the health effects of resveratrol on humans. The level of resveratrol generally used in current research on animals is equivalent to a human consuming several hundred glasses of red wine each day, which would have serious negative health effects.

 

Moderate consumption of wine, meaning one to two glasses per day, may actually be good for your health according to Dr. Curtis Ellison, Chief of Preventive Medicine at Boston University (Moderate Wine Consumption and Health: A Scientific Perspective). Historically, physicians have recommended wine for the treatment of iron deficiency, to help vegetarians increase their mineral absorption, and to help reduce the incidence of troublesome sleep disorders. The traditional use of wine with meals offers many benefits including aiding the digestive process, stimulating the intake of nutrients and helping reduce the risk of coronary heart disease by reducing cholesterol.

 

The term “French Paradox” refers to the fact that per capita alcohol consumption, in the form of wine, and saturated fat intake in France are very high, but levels of coronary heart disease in that country are relatively low. Researchers have discovered that one reason for the low rate of coronary heart disease is the presence of phenolic compounds or antioxidants such as “resveratrol” in wine, especially red wine. Studies show that resveratrol lowers LDL cholesterol (the so-called “bad”) while elevating HDL cholesterol (the “good”) levels, which helps to clear arterial walls of harmful deposits (Mississippi Agricultural & Forestry Experimental Station, Vol. 58, No. 2).

 

Recent studies have found muscadine grapes and their resulting products to contain more resveratrol and other antioxidants than any other types of grapes. Muscadine grapes contain antioxidants in skins, seed, pulp, juice and wine.

Dr. Arthur Klatsky, chief of the Division of Cardiology at the Oakland-based Kaiser Permanente Medical group monitored 8,000 people for 10 years. The results (published in Alcohol and Mortality: A New, Prospective Kaiser Permanente Study, Annals of Internal Medicine, 117, 1992) showed that people who drink one or two glasses of wine per day live longer and are less likely to die from all causes than either abstainers or heavy drinkers.


Indeed, scientific researchers have found repeatedly that moderate daily wine consumption actually appears to be more beneficial than either zero consumption or over-consumption.A healthy lifestyle also includes regular exercise and a diet low in fat and high in fresh fruit, vegetables, and grains.

 

The 1995 Dietary Guidelines for Americans, the official United States nutrition policy, advises, “If you drink alcoholic beverages, do so in moderation, with meals, and when consumption does not put you or others at risk.” The Dietary Guidelines define moderation as “no more than one drink per day for women and no more than two drinks per day for men.” For those adults who include wine in their lifestyle:

 

Wine should be consumed only in moderation, and preferably around mealtime.
Wine consumption should be part of social, family, celebratory or other occasions, but not as their central focus.
Excessive consumption should be discouraged, and the choice of abstinence for religious, health or personal reasons must be respected.

The Health Benefits of Muscadine Grapes, Wines and Nutraceuticals

SPECIAL CAROLINAS EDITION, EASTERN NORTH CAROLINA & SOUTH CAROLINA M.D. NEWS SUMMER 2008

 

        It’s North Carolina’s state fruit, it tastes delicious and it’s an emerging nutrition superstar. Native to North Carolina, scuppernong and other muscadine grapes are grown in the backyards of many Eastern North Carolina homes. They are among the richest sources of antioxidants found in nature. Muscadine grapes are a leading food source for a potent cancer-fighting substance called resveratrol. A theory about why resveratrol is protective in humans and animals is that our genes respond to plant defensive chemicals in a beneficial way. Plantings of native muscadine grapes, also known as scuppernongs, are relatively pest resistant and thrive in the hot, sandy conditions of the coastal region. The coastal climate necessitates resistance to disease, viruses, bacteria, pests and mold. The plant’s adaptation to these conditions has developed unique properties that have significant health benefits for those who consume the muscadine grape.

The typical American consumes only two or three servings of fruit and vegetables a day. A single 1-cup serving of muscadine grapes would more than double the average person’s antioxidant intake. That positions muscadines and scuppernongs in the elite list of powerful antioxidant foods that includes blueberries, plums, pomegranate, blackberries, cranberries and raspberries.

 

Muscadine grapes are fat free, high in fiber and they are high in antioxidants, especially ellagic acid and resveratrol. Ellagic acid has demonstrated anticarcinogenic properties in the colon, lungs and liver of mice. Resveratrol is reported to lower cholesterol levels and the risk of coronary heart disease. This article reports on a growing body of research on the health benefits of drinking wine or taking the nutraceuticals, but it’s important to note that the beneficial effects are also in the grapes themselves. Eating the fruit alone, in desserts, sauces or juice can give health benefits.

 

MUSCADINES AND HEART DISEASE

 

Researchers have wondered for years how the French could eat a diet rich in cream, butter and cheese, resulting in a high-fat diet equivalent to the American diet, yet the French have a much lower incidence of heart disease than Americans. France’s heart attack rate is one-third that of the U.S. The answer is the French custom of drinking wine with meals. The Copenhagen City Heart Study, published in the British Medical Journal, showed that among more than 13,000 men and women aged 30 to 70 who were tracked for 12 years and consumed wine daily, 50% less likely to die during the study than consumers of other alcoholic beverages or nondrinkers. It’s important to note that health benefits were greatest with only two or three glasses of wine per day (one for women). Drinking more increased health risks.

 

DIABETES, METABOLIC SYNDROME AND WEIGHT CONTROL

 

Metabolic syndrome is a combination of interacting metabolic disorders including impaired glucose tolerance, decreased insulin sensitivity, hyperglycemia, lower HDL cholesterol (known as the “good cholesterol”), high triglycerides and usually elevated total cholesterol. Persons with metabolic syndrome have an increased risk of developing diabetes, heart disease, atherosclerosis and stroke. Metabolic syndrome is an epidemic in populations that consume high-calorie diets and live a sedentary lifestyle (e.g., many Americans).

 

Abdominal obesity and hypertension are often present with metabolic syndrome. A university study examined “central adiposity”— the fat around our midsections in over 12,000 people. “Increases in waist-to-hip ratio,” explained University of North Carolina, Chapel Hill researcher Bruce Duncan, “predicted increases in risk of death in the Iowa Women’s Health Study.” In popular terms, being shaped like an apple increases the risk of heart disease. Several studies have shown that moderate consumption of wine (one or two glasses per day), as part of a healthy diet, did not contribute to weight gain, compared to other types of alcoholic beverages.

 

Drinking wine with meals is shown to have greater health benefits than drinking wine by itself, according to research done in Italy on 70,000 subjects. Wine is traditionally consumed at mealtimes and for centuries has occupied a prominent place on the dinner table in many cultures around the world. Drinking with dinner assures that the protective effects of alcohol are strongest in the evening, when fats from the dinner meal circulate through the bloodstream, and carry over to the next morning when most heart attacks take place. Recent research shows that muscadine juice and muscadine wine have a positive effect on type 2 diabetes by decreasing blood-glucose levels, improving cholesterol status, lowering triglycerides and prevention of blood clotting. Muscadine wines have significantly more resveratrol than wines from other grape varieties. If you don’t want to drink muscadine wine, however, you can get the health benefits by taking an antioxidant dietary supplement containing resveratrol. Health benefits were greatest with only two to three glasses of wine a day (one for women). Drinking more increases health risks.

Muscadine grapes, wines and nutraceuticals may be beneficial in prevention of heart disease and cancer.

 

CANCER PREVENTION

 

Recent tests show that resveratrol from muscadine grapes can block cancer cells from attacking organs, thus preventing spread of the disease once it starts. Andrew Dannenberg, Director of Clinical Programs at the Strang Cancer Prevention Center in New York City, showed that resveratrol was very effective as an inhibitor of the growth of COX, a compound present in breast cancer and other cancers. Compounds that inhibit COX are considered very promising agents in preventing cancer by making cancer cells vulnerable to the body’s natural defenses. Initial studies showed that resveratrol inhibits tumor growth at three different stages —initiation, promotion and progression.

 

Prostate cancer patients received information about muscadine grape-skin extract (MKSE), reported in Cancer Research in September 2007. Using a series of human prostate cancer cells representing different stages of prostate cancer progression, the researchers showed MSKE significantly inhibited tumor cell growth in all prostate cancer cell lines, exhibiting high rates of apoptosis (programmed cell death).

 

Results showed that MSKE and resveratrol target distinct pathways to inhibit prostate cancer cell growth and the unique properties of MSKE suggest that it may be an important source for further development of chemopreventive or therapeutic agents against prostate cancer. Anthocyanins, which produce the red and purple colors of the grapes, have strong antioxidant activity and have shown several anti-tumor effects, including inhibition of DNA synthesis in breast cancer cells, of blood-vessel growth in some tumors and of enzymes involved in tumor spread. Tests in cell culture have shown that berry extracts including muscadine (which is a berry) reduce cancer cell growth (or cause increased cancer cell death) in colon cancer, breast cancer, prostate cancer and leukemia models.

 

Resveratrol taken orally also protects the skin from damage that leads to skin cancer. A review of 70 published studies concluded that resveratrol treatment helped prevent damage to skin and stopped the development of cancer cells.

Ellagic acid, which is abundant in muscadines, raspberries, black raspberries, strawberries and walnuts, is powerful in chemoprevention of cancer. Chemoprevention eliminates the need for chemotherapy because the cancer does not occur. Ellagic acid is being aggressively investigated for chemoprevention.

 

LONGEVITY

 

Subjects fed resveratrol were healthier, leaner and lived up to 30% longer, even though they were on high-calorie, high-fat diets, according to an ongoing Harvard study. Researchers believe that resveratrol activates the same genetic longevity pathways as calorie restriction, the only diet known to extend lifespan.

 

LONGEVITY AND MENTAL FUNCTION

 

New studies at the Harvard Medical School and the Institute of Genetics and Molecular and Cellular Biology have found that resveratrol, a natural antioxidant found in red wine grapes, may radically reduce the risk not only of heart disease, but also of age-related illnesses such as Alzheimer’s disease. It may also counteract the effects of a high-fat diet and even prolong life. “This could arguably be the biggest medical discovery since antibiotics,” says Joseph Baur, Ph.D., an author of the Harvard study. It is believed that the assortment of antioxidants found in muscadine grapes and the seeds slow the effects of aging and possibly extend life. Coupled with smart dietary choices, avoidance of risk factors and physical activity, plus eating of muscadine grapes or taking grape supplement can add 10 years to your life. In the Harvard study, mice that were fed the substance resveratrol were healthier, leaner and lived up to 30% longer, even though they were on high-calorie, high-fat diets. Dr. Baur believes that resveratrol activates the same genetic longevity pathways as calorie restriction, the only diet known to extend life span.

 

Maintaining good mental function as we age is important. Oxidative stress (i.e. free radical damage) is part of what makes the brain age and cause degenerative conditions, such as dementia and Alzheimer’s. The American Journal of Epidemiology reported on a French study, called the Paquid study, wherein 1,640 subjects aged 65 years or older and free from dementia at baseline, were tested over a 10-year period. Subjects with higher antioxidant flavonoid intake had better cognitive evolution than other subjects. The researchers also determined that antioxidant flavonoid intake was inversely related to risk of dementia. Quercetin, which was cited in the study, is a flavonoid that is found in high concentration in muscadine grapes and grape seeds.

 

ANTIOXIDANTS FIGHT FREE RADICAL DAMAGE

 

Your real age can be thought of in two ways: your biological age or the amount of free radical damage that has occurred within your body. A free radical assaults cells in the body to find a partner for its unpaired electron. The highly charged, highly unstable molecular fragment punctures cell membranes, destroys enzymes and even breaks down DNA to steal an electron from another molecule. Some free radicals occur naturally, as cells burn food for energy. Other free radicals derive from exposure to ultraviolet radiation (sunlight), radon, X-rays, pollutants, pesticides, food additives, alcohol and other toxins. An antioxidant can neutralize a free radical by donating one of its electrons without jeopardizing its own chemical stability. Left unchecked, free radicals start chain reactions that damage cells. Antioxidants terminate these chain reactions by being oxidized themselves.

 

Antioxidants are a class of molecules that includes polyphenols, flavonoids and isoflavones. The family of antioxidants found in muscadine grapes, seeds and skins includes resveratrol, ellagic acid, quercetin,

 

Health benefits were greatest with only two or three glasses of wine a day (one for women).
