Of all cultivated fruits, blueberries are one of the best for the home garden. The beautiful bushes blend well into landscaping, growing four to eight feet tall with small, white urn-shaped flowers in spring followed by big crops of blue berries and lovely autumn foliage. Nutritional research has shown that blueberries provide more antioxidants for good health than any other fruit.
Oxidative DNA damage is part of everyday life.It is said to occur tens of thousands of times per day, in every single cell in the body. DNA damage is part of the reason we grow older, and it also plays an important role in the development of diseases like cancer (11).Because blueberries are high in antioxidants, they can help neutralize some of the free radicals that cause damage to our DNA.In one 4-week study, 168 participants were instructed to drink 1 liter (34 ounces) of a mixture of blueberry and apple juice, every day.
Oxidative damage is not limited to our cells and DNA.It is also problematic when our circulating LDL lipoproteins (the "bad" cholesterol) are oxidized.In fact, oxidation of LDL is a crucial step in the heart disease process.Fortunately for us, the antioxidants in blueberries are strongly linked to reduced levels of oxidized LDL. A daily 50 gram serving of blueberries lowered LDL oxidation by 27% in obese participants, after a period of eight weeks.
