Benefits of Strawberry

Strawberries are a fragrant, red-colored, ground-dwelling fruit.
Many foods commonly consumed in the U.S. are valuable sources of antioxidants. But researchers have recently ranked the 50 best antioxidant sources among commonly eaten foods and found strawberries to be quite exceptional. When total antioxidant capacity was measured against a uniform amount of food (100 grams, or about 3.5 ounces), strawberries ranked 27th best among U.S. foods.
In addition, when only fruits were considered, strawberries came out 4th among all fruits (behind blackberries, cranberries, and raspberries).

When we hear the word "strawberry," we might think about a very commonplace fruit. But the antioxidant capacity of strawberry is anything but common!
The strawberry is often described as a luxury item, enjoyed by royalty.
The use of strawberries and of the strawberry plant itself for therapeutic purposes dates back as long as they have been eaten. American Indians prepared infusions of strawberry plant leaves as a treatment for stomach pain and gastrointestinal ailments such as diarrhea. Swedish botanist Carl Linnaeus was convinced that strawberries had miraculously healed his severe attack of gout; and the French philosopher Bernard de Fontenelle, who died at the age of 100, attributed the secret of his longevity to strawberries. 
Strawberries also contain a large amount of antioxidant, anticancer, anti-neurodegenerative, and anti-inflammatory properties, making them, like many other berries, very useful as a natural alternative to western medicine.
·         No area of strawberry health benefits is better documented than benefits for the cardiovascular system. It's also hard to imagine any other research result, since our heart and blood vessels need everyday protection from oxidative and inflammatory damage, and the antioxidant and anti-inflammatory nutrient content of strawberries is simply outstanding. Among all fruits profiled as the World's Healthiest Foods, strawberries come out as the best fruit source of a pivotal antioxidant vitamin. Several research studies have shown that the diverse strawberry phytonutrients actually work together in synergistic fashion to provide their cardiovascular benefits.
·         One of the more recent areas of health benefit to be documented in strawberry research is the area of blood sugar benefits. Several recent studies have found regular intake of strawberries to be associated with decreased risk of type 2 diabetes.
·         Since chronic, excessive inflammation and chronic, excessive oxidative stress (lack of antioxidant nutrients and unsupported oxygen metabolism) are often primary factors in the development of cancer, strawberries would definitely be expected to have cancer risk-lowering properties given their outstanding antioxidant and anti-inflammatory nutrient content. Anti-cancer benefits from strawberries are best documented in the case of breast, cervical, colon, and esophageal cancer. More specifically, ellagic acid prevents the destruction of P53 gene by cancer cells. Ellagic acid can also bind with cancer causing molecules, thereby making them inactive. Strawberries have also been shown to significantly reduce liver cancer cells.
·         Decreased oxidation of fats (lipid peroxidation) in the cell membranes of cells that line our blood vessels; decreased levels of circulating fats, including total cholesterol and LDL cholesterol; and decreased activity of angiotensin I-converting enzyme (ACE), an enzyme whose over activity increases our risk of high blood pressure are results that have all been documented following daily intake of strawberries over 1-3 months period of time. Amounts of strawberries in most studies were equivalent to 1-2 cups of strawberries per day.
·         A growing area of health research on strawberries is the area of aging and aging-related events. In addition to their known beneficial effects on cancer and heart disease, the antioxidant qualities of strawberries may also be beneficial in reversing the course of neuronal and behavioral aging. Due to their positive effects against anti-neurodegenerative diseases, strawberries are helpful in slowing the onset and reduce the effects of Alzheimer’s disease.
·         Improvement of inflammatory bowel problems including ulcerative colitis and Crohn's disease - has also been demonstrated in preliminary studies on animals with daily strawberry extract or strawberry powder intake. Interestingly, even though strawberries contain relatively small amounts of salicylic acid (an anti-inflammatory compound very similar to the acetylsalicylic acid of aspirin), some researchers have suggested that this naturally-occurring anti-inflammatory substance in strawberries might be partly responsible for decreased inflammation in the digestive tract of individuals diagnosed with inflammatory bowel diseases like ulcerative colitis or Crohn's disease.
·         Inflammation-related arthritis (including rheumatoid arthritis), and inflammation-related diseases of the eye (including macular degeneration) are two additional areas in which strawberries may turn out to provide important health benefits. Even though health research in these areas is in a preliminary stage, the unique combination of anti-inflammatory phytonutrients in strawberries is likely to explain some of the key potential benefits in these areas.
·         Strawberries are an excellent source of dietary fiber and Vitamins C and K. They are a very good source of manganese, pantothenic acid, vitamin B1, and iodine. They are a good source of folic acid, biotin, and vitamin B6. Strawberries contain high levels of antioxidants, which can decrease the risk of chronic disease.
·         Strawberry extracts have also been shown to inhibit COX enzymes in vitro, which inhibits the inflammatory process.
·         One cup of strawberries contains over 13% of the RDA of dietary fiber, yet only 43 calories. The dietary fiber in strawberries helps to keep digestion regular, as well as lowers blood pressure and curbs overeating.
·         Manganese is also great for the bones, helping in bone building and maintaining proper bone structure. The potassium, vitamin K, and magnesium in strawberries are also important for bone health.
·         Folate is known to protect from birth-defects. Vitamin-C effectively prevents from infections and cold. The phytonutrients also have anti inflammatory properties.
·         Strawberries are also used to whiten teeth. The acids in the fruit are said to help remove stains from the teeth. Cut a strawberry into half and rub it on your teeth and gums. This removes tartar and strengthens and heals the gums. Leave the juice on the teeth for a while and then gargle with warm water.
·         Strawberries are virtually fat free; therefore they are ideal and perfect food for your diet. Studies suggest that one cup of strawberries contain only 0.6 grams of fat. They suppress your appetite and stimulate your metabolism; they also help keep your weight reducing hormones functioning properly.

Side Effects:
Additional research in 2011 has also shown non-organically grown strawberries to contain a high number of pesticide residues, including residues from 14 different pesticides. Therefore, individuals wanting to avoid pesticide-associated health risks may want to avoid consumption of strawberries unless they are grown organically.
Strawberries are among a small number of foods that contain measurable amounts of oxalates, naturally-occurring substances found in plants, animals, and human beings. When oxalates become too concentrated in body fluids, they can crystallize and cause health problems. For this reason, individuals with already existing and untreated kidney or gallbladder problems may want to avoid eating strawberries.
Strawberries, with their common scientific name Fragaria (there are different suffixes for different varieties, such as Fragaria Vesca for wild strawberry, Fragaria Orientalis for Eastern Strawberries etc.), are berries which grow in bushes.
