We all know the proverb "an apple a day," but equally an orange
could be recommended. There are thousands of reasons why eating an
orange a day is a good idea; they are low in calories but full of
nutrients, they promote clear, healthy skin and can help to lower our
risk for many diseases and conditions as part of an overall healthy and
varied diet.
Possible health benefits of consuming oranges
Stroke: According to the American Heart
Association, eating higher amounts of a compound found in citrus fruits
like oranges and grapefruit may lower ischemic
stroke
risk for women. Those who ate the highest amounts of citrus had a 19
percent lower risk of ischemic stroke than women who consumed the least.
Blood pressure: Maintaining a low sodium intake is essential to lowering
blood pressure,
however increasing potassium intake may be just as important because of
its vasodilation effects. According to the National Health and
Nutrition Examination Survey, fewer than 2 percent of US adults meet the
daily 4700 mg recommendation.
Also of note, a high potassium intake is associated with a 20 percent decreased risk of dying from all causes.
Cancer: According to a study published in the American Journal of Epidemiology, consuming
bananas, oranges and orange juice in the first two years of life
may reduce the risk of developing childhood leukemia.
As an excellent source of the strong antioxidant vitamin C, oranges
can also help combat the formation of free radicals known to cause
cancer. While an adequate vitamin C intake is necessary and very
beneficial as an antioxidant, the amount necessary to consume for
therapeutic purposes for cancer is beyond oral intake. High fiber intakes from fruits and vegetables are associated with a lowered risk of
colorectal cancer.
Heart health: The fiber, potassium, vitamin C and
choline content in oranges all support heart health. An increase in
potassium intake along with a decrease in sodium intake is the most
important dietary change that a person can make to reduce their risk of
cardiovascular disease, according to Mark Houston, M.D, M.S, an
associate clinical professor of medicine at Vanderbilt Medical School
and director of the Hypertension Institute at St. Thomas Hospital in
Tennessee.
In one study, those who consumed 4069 mg of potassium per day had a 49 percent lower risk of death from ischemic
heart disease compared with those who consumed less potassium (about 1000 mg per day).
High potassium intakes are also associated with a reduced risk of
stroke, protection against loss of muscle mass, preservation of bone
mineral density and reduction in the formation of
kidney stones.
Diabetes: Studies have shown that type 1 diabetics
who consume high-fiber diets have lower blood glucose levels and type 2
diabetics may have improved blood sugar, lipids and insulin levels. One
medium banana provides about 3 grams of fiber.
The Dietary Guidelines for Americans recommends 21-25 g/day for women and 30-38 g/day for men.
Skin: The antioxidant vitamin C, when eaten in its
natural form (as in an orange) or applied topically, can help to fight
skin damage caused by the sun and pollution, reduce wrinkles and improve
overall skin texture. Vitamin C plays a vital role in the formation of
collagen, the support system of your skin.
