Blueberries contain vitamins A and C, zinc, potassium, iron, calcium and magnesium, are high in fiber and low in calories. The USDA Human Nutrition Center (HNRCA) has ranked blueberries at the very top of antioxidant activity within a range of forty-one fruits and vegetables.
Blueberries are rich in natural health-enhancers, including vitamin C, vitamin A, zinc, potassium, iron, calcium and magnesium. They also have many antioxidant properties, and help in the prevention of:
- Metabolic Syndrome
Brain-damage from ischemia and strokes
Blueberries have recently acquired a reputation for enhancing one’s cardiovascular health, and their antioxidants naturally help in the prevention of cancer. Recent research has added to the blueberry’s list of powerful properties.
Metabolic syndrome, or pre-diabetes, is exhibited in those with a particular combination of health anomalies, including larger-than-normal amounts of abdominal fat, elevated blood-sugar, high blood pressure, and high triglycerides. Together, those conditions are likely to cause diabetes, cardiovascular disease, heart attacks, and strokes.
Laboratory-rats that for 90 days consumed blueberry-enriched powder as two percent of their diet had less abdominal fat, lower triglycerides, lower cholesterol, and improved fasting glucose and insulin sensitivity than the control-group, who had no blueberry component in their diets.
Blueberry ingestion was determined to have a positive affect on specific genes related to fat-burning and fat-storage. Where muscle tissue is concerned, alterations in genes related to glucose-uptake were discovered to have been caused by the intake of blueberries.
Research also indicated that “metabolic syndrome” is caused not only by abdominal fat, as previously believed by the medical industry, but by insulin resistance in one’s skeletal muscle system, an anomaly which alters energy-storage and causes metabolic syndrome.
Eating blueberries can help to prevent insulin-resistance, lower the related belly-fat, reduce cholesterol levels, and its numerous antioxidants can help to stave-off age-related brain disorders.
Blueberries contain an antioxidant compound called pterostilbene, a compound similar to resveratrol, which has been found to reduce cholesterol as well as dangerous prescription drugs.
Just as dried cherries do, blueberries, when added to ground beef before cooking, help reduce the formation of cancer-causing heterocyclic amines (HCA).
In Europe, the bilberry has most of the same properties as the blueberry. One of the many things they have in common is anthocyanin, the substance that makes them blue, which is beneficial to the cardiovascular system and is believed to lower blood-pressure. Bilberries have been used to enhance eyesight since World War 11, when pilots who ate bilberry jam attributed their improved night-vision to the tiny fruit. Bilberries are also said to aid in relief of varicose veins and gum-disease as they promote healthy circulation. Caution must be taken with bilberries by those who are taking blood-thinnning drugs, as they are a natural blood-thinner.
Blueberries can be added to a morning smoothie that you make with yogurt in a blender, together with whatever other fruits you have in stock. Frozen blueberries can be much less expensive than fresh ones, easier to store, and retain most of their antioxidant properties. When used in a smoothie, frozen blueberries make it ice-cold (see my photograph). This preparation makes a health-promoting breakfast, and is delicious as well. Staying well is the best thing you can do in this ailing world.
