An extensive and growing body of research suggests that the powerful antioxidants in tart cherries that give the super fruit its bright red color are also responsible for their anti-inflammatory properties and health benefits. Tart/sour cherries are not the same variety as summery sweet, dark red cherries.
A number of studies have specifically linked tart cherry consumption and cherry anthocyanins to decreased inflammation and inflammatory-related conditions. One study from University of Michigan researchers revealed a cherry-enriched diet reduced inflammation markers in animals by up to 50 percent and another found drinking eight ounces of tart cherry juice daily for four weeks significantly reduced important markers of inflammation in overweight and obese adults.
This inflammatory benefit is behind cherries’ ability to reduce risk for arthritis and gout, promote cardiovascular health and most recently to aid muscle recovery and reduce oxidative stress in athletes.
GOUT AND ARTHRITIS
For decades arthritis and gout sufferers have regularly consumed tart cherry juice for relief of symptoms. As early as the 1950’s, the science began to support this long-held tradition, linking cherry consumption to less pain associated with gout attacks.
More recent studies have supported this finding. One study found that when healthy women ate two servings (280 grams) of cherries after an overnight fast, they showed a 15 percent reduction in uric acid levels, as well as lowered nitric oxide and C-reactive protein levels – all of which is associated with inflammatory diseases like gout. Another study supported a lower uric acid level after cherry consumption, finding that after drinking eight ounces of tart cherry juice daily for four weeks, many adults had lower levels of uric acid.
The inflammatory benefits have potential to extend to arthritis sufferers too. In a 12-week pilot study conducted by researchers at Baylor Research Institute, a daily dose of tart cherries (as cherry extract) helped reduce osteoarthritis pain by more than 20 percent for the majority of men and women.
CARDIOVASCULAR AND HEART HEALTH
Tart cherry consumption has been linked to a number of cardiovascular benefits — from overall anti-inflammation to reductions in cholesterol levels, to decreased risk for atherosclerosis and metabolic syndrome — all important heart disease risk factors.
Research from the University of Michigan has found that cherry-enriched diets in animals lowered multiple risk factors for heart disease, from lowering total blood cholesterol levels to reducing total body weight and fat, in particular the “belly fat” that is most often associated with heart disease risk. A recent study found that a cherry diet (at 1 percent of diet as tart cherry powder) reduced C-reactive protein and other markers of inflammation by up to 36 percent and lowered levels of total cholesterol by 26 percent in a five-month mouse study. The mice fed a cherry diet had a 65 percent reduction in early death, likely due to improved cardiovascular health.
The University of Michigan researchers also found the cherry-enriched diets reduced not only overall body inflammation, but inflammation at key sites (belly fat, heart) known to affect heart disease risk in obese, at-risk rats.
The anthocyanins in tart cherries may also lower blood lipid levels. In an animal study, rats who were fed tart cherry-enriched diets for 90 days demonstrated significantly lower plasma triglyceride and total cholesterol, fasting glucose and insulin, and a plasma marker of oxidative damage.They also had slightly higher high-density lipoproteins (HDL – the “good” cholesterol) and significantly elevated blood antioxidant capacity.
EXERCISE RECOVERY AND PAIN RELIEF
The same RED compounds linked to cherries’ arthritis and cardiovascular benefits have now shown promise for athletes and sports recovery to help relieve muscle and joint soreness. Tart cherries could help athletes reduce muscle damage to recover faster from a tough workout, according to a growing body of research.54-56
A study conducted at the University of Vermont gave 12 ounces of cherry juice or a placebo twice a day for eight days to 14 college men. On the fourth day, the men were asked to perform strenuous weight lifting of two sets of 20 repetitions each. Strength loss after exercise was only 4 percent with the juice compared to 22 percent with the other beverage, and pain significantly decreased after cherry juice consumption. The researchers concluded that “consumption of tart cherry juice before and after eccentric exercise significantly reduced symptoms of muscle damage.”
Other research supports the pain relief benefits of incorporating tart cherries in a training routine. In one study, runners who drank cherry juice twice a day for seven days prior to and on the day of a long-distance relay had significantly less muscle pain following the race. A similar study in marathoners found that runners who drank cherry juice 5 days before, the day of and 2 days after running a marathon experienced a faster recovery of strength, increased total antioxidant capacity and reduced inflammation and lipid peroxidation compared to a non-cherry beverage.
Cancer-Fighter Perillyl Alcohol Found in Tart Cherries
Research at the University of Iowa is showing the amazing properties of cherries. According to Raymond Hohl, M.D., at the University of Iowa, tart cherries contain perillyl alcohol (POH), a natural compound that is extremely powerful in reducing the incidence of all types of cancer. Perillyl alcohol “shuts down the growth of cancer cells by depriving them of the proteins they need to grow,” explains Dr. Hohl. “It works on every kind of cancer we’ve tested it against.”
Independent Lab Verifies Cancer-Fighting Agents in Tart Cherries
Researchers at Brunswick Laboratories (Wareham, MA) verified the presence of natural antioxidants present in Montmorency tart cherries, the leading U.S. tart cherry variety. Lead researcher Boxin Ou, Ph.D., also confirmed the presence of substantial quantities of melatonin. He also identified two important flavonoids—isoqueritrin and queritrin—and documented the presence of ellagic acid in cherries.
Ellagic acid is a naturally occurring plant phenolic known to be a potent anti-carcinogenic/anti-mutagenic compound. Clinical tests conducted at the Hollings Cancer Institute at the Medical University of Southern Carolina (MUSC) show that ellagic acid may be the most potent way to prevent cancer. It also may inhibit the growth of cancer cells and arrest the growth of cancer in subjects with a genetic predisposition for the disease.
The flavonoids isqueritrin and queritrin act as antioxidants, as do the anthocyanins. They work to eliminate byproducts of oxidative stress and thereby slow the aging process.
High Quantity of Melatonin Identified in Tart Cherries
The University of Texas Health Science Center recently began to quantify the availability and activity of the melatonin in cherry products. Melatonin is a potent antioxidant for which there is extensive evidence showing it to be significant in improving the body’s circadian rhythms and natural sleep patterns. Melatonin is rapidly absorbed by the body, and it is predicted that eating just a handful of cherries will increase melatonin levels in the blood, thereby improving the body’s natural sleep patterns.
As we grow older, we produce less and less melatonin. Also, if there is some sort of trauma in our lives at any time, we do not produce as much melatonin. This could have a great deal to do with why people are not sleeping well. Perhaps it is more than stress; it is because they are not producing enough melatonin to tell them that it is time to sleep.
Russel Reiter, Ph.D., University of Texas Health Science Center, is said to be the “dean” of melatonin research and he gives cherries high marks. We were surprised at how much melatonin was in cherries, specifically the Montmorency variety, says Reiter. And Tart Cherry Concentrate, which has greatly reduced water content, contains ten times the melatonin of the raw fruit. Tart cherries contain an extremely significant amount of melatonin, enough to produce positive results in the body.
Montmorency cherries, which account for the majority of tart cherries produced in the United States, contain up to 13.5 nanograms (ng) of melatonin per gram of cherries, more than is normally found in the blood. Melatonin is by far the most potent of the antioxidants, much more so than vitamins C, E, and A. The reason: melatonin is soluble both in fat and water and can therefore enter some cells that vitamins cannot. For example, vitamin E is soluble in the lipid part of the cell only and vitamin C in the aqueous part. Melatonin is soluble in both. For this reason, Dr. Reiter says, eating cherries with high melatonin concentrations will increase the antioxidant capacity in the body.
In addition to its antioxidative properties, melatonin has been shown to possess anti-inflammatory properties.
Michigan State University First to Identify Anthocyanins in Tart Cherries
“Twenty cherries provide 25 mg of anthocyanins which help shut down the enzymes that cause tissue inflammation in the first place, so cherries can prevent and treat many kinds of pain,” states Muraleedharan Nair, Ph.D., Michigan State University researcher. Anthocyanins are the plant pigments responsible for the bright red color of cherries. These pigments are known to have antioxidant activity, and antioxidants are believed to play a role in reducing the risk of various human degenerative diseases. Tart cherries contain anthocyanins and flavonoids, which prevent inflammation in the body. These compounds exhibit similar activity as do aspirin, naproxen, and ibuprofen. The anthocyanins may also protect artery walls from the damage that leads to plaque build-up and heart disease. Recent studies show that anthocyanins do a better job of protecting arteries than vitamins C and E.
There are 17 antioxidants in tart cherries. Two of these, anthocyanins 1 and 2, can inhibit the cyclooxygenase (COX) enzymes, which are associated with the pain of arthritis and gout. In a comparison of 10 small fruits, cherries had the highest level of anthocyanins 1 and 2. Anthocyanins 1 and 2 are not present in blueberries or cranberries.
New studies at Michigan State University (MSU), which were recently published in Cancer Letters, suggest that tart cherries may reduce the risk of colon cancer because of the anthocyanins and cyanidin they contain.
