Oranges are one of the most popular fruits around the world. An orange has over 170 different
phytonutrients and more than 60 flavonoids, many of which have been shown to have antiinflammatory,
anti-tumor and blood clot inhibiting properties, as well as strong antioxidant
effects. You may already know, oranges are an excellent source of vitamin C which is the main
water-soluble antioxidant in the body, fighting free radicals and preventing damage in the
aqueous environment both inside and outside cells which could damage DNA and cause cancer.
Especially in areas such as the digestive system, preventing DNA mutations would prevent colon
According to report released by Australian research group, CSIRO (The Commonwealth
Scientific and Industrial Research), “The Health Benefits of Citrus Fruits,” a diet high in citrus
fruit provides a statistically significant protective effect against some types of cancer. Another
study reviewed in the CSIRO report shows that one serving of citrus fruit a day reduces the risk
of stroke by 19%. Citrus appears to offer the most significant protection against esophageal,
oropharyngeal/laryngeal (mouth, larynx and pharynx), and stomach cancers. For these cancers,
studies showed risk reductions of 40-50%.
The CSIRO Report also shows evidence of positive effects of citrus consumption for arthritis,
asthma, Alzheimer’s disease, cognitive impairment, Parkinson’s disease, macular degeneration,
diabetes, gallstones, multiple sclerosis, cholera, gingivitis, optimal lung function, cataracts,
ulcerative colitis and Crohn’s disease.
Finally, the CSIRO Report notes that as low fat, nutrient-rich foods with a low glycemic index,
citrus fruits are protective against overweight and obesity, conditions which increase the risk of
heart disease, diabetes, high blood pressure and stroke.
Vitamin C in orange, also prevents the free radical damage that could cause inflammatory
cascade, is thus also associated with reduced inflammatory conditions, like asthma,
osteoarthritis, and rheumatoid arthritis and it is also essential for the immune system, and
would prevent colds and infections.
According to a report by The World Health Organization, “Diet, Nutrition and the Prevention of
Chronic Disease,” a diet with citrus fruits offers protection against cardiovascular disease due to
citrus fruits—folate, which is necessary for lowering levels of the cardiovascular risk factor,
homocysteine; their, potassium, which helps lower blood pressure, protecting against stroke
and cardiac arrhythmias; and the vitamin C, carotenoids and flavonoids found in citrus fruits, all
of which have been identified as having protective cardiovascular effects.
Grapefruit is an excellent source to support the immune system and help reduce cold
symptoms or severity of cold symptoms, could reduce severity of inflammatory conditions, such
as asthma, osteoarthritis, and rheumatoid arthritis and is beneficial to promote cardiovascular
Consuming grapefruit may greatly reduce a man’s risk of developing prostate cancer, suggests
research published in Asia Pacific Journal of Clinical Nutrition (Jian L, Lee AH, et al.)
Grapefruit can reduce cholesterol as shows a study published in the Journal of Agricultural and
Food Chemistry and could significantly drop risk of forming kidney stones.
Pineapple is not only valued for its taste, but has been used to treat digestion and inflammation
problems. Pineapple is also a source of important vitamins and minerals such as thiamin,
riboflavin, vitamin B-6, folate, pantothenic acid, magnesium, manganese, potassium, and
antioxidants and polyphenols, such as beta carotene. The fiber, potassium, and vitamin C
content all support heart health.
