Nature’s antioxidants


Studies have shown that a diet rich in antioxidants, which are primarily provided by fruits and vegetables, may help prevent a variety of serious diseases Among the best known antioxidants are vitamins C and E, beta-carotene, selenium, ubiquinone (Q10) and the flavonoids found in wine, apples, onions and tea.

Surprisingly, cooked artichokes were found the highest-ranking vegetable-antioxidant. Even more of surprise was the discovery of antioxidative properties of potato placed on the top twenty list. (Health Evidence Network, WHO)

Comparing 40 fruit and beriries for their antioxidative activities researchers put wild blueberries to # 1 position. Among many health benefits listed were: memory and heart support, vision protection, urinary tract health, and cancer prevention. Cultivated blueberries were rated lower than their wild relatives (Journal of Agricultural and Food Chemistry, 52: 4026-4037, 2004)

Not only wild blueberries, but other berries such as: dog rose, sour cherry, blackberry, strawberry, raspberry, crowberry, and especially black currant are now considered potent antioxidants. Cranberries ranked sixth, with blackberries eighth, raspberries tenth, and strawberries eleventh. (August 1, 2004 -- Vegparadise News Bureau)

The long-lasting champion championship of blueberries as antioxidants, recently a new candidate for the position has been announced - small red kidney beans, leaving blueberries slightly behind and pinto and black beans seriously down the list.

Free radicals are to blame for Alzheimer's and Parkinson' s diseases

Logically speaking, anti-oxidants are substances that fight oxidants. Then what are oxidants? They are chemicals producing unstable form of oxygen, which make them deadly for some life forms and dangerous for the others. To name just two, chlorine and chloramines are oxidants and are used for disinfection – killing the microbes.

Now, antioxidants are chemicals (naturally occurring or synthesized) that absorb or scavenge and finally neutralize oxidants also known as free radicals. High levels of free radicals may eventually lead to damage of bodily cells and is believed are responsible for many diseases.

It is agreed upon that free radicals are to blame for diseases associated with long lasting oxidant stress: cardiovascular disease, diabetes, the most common forms of cancer, eye diseases, neurological diseases, infectious diseases, and rheumatoid arthritis, adult respiratory distress syndrome, drug induced lung lesions, chronic obstructive pulmonary diseases, asthma, emphysema, interstitial fibrosis, Alzheimer's disease, and Parkinson' s disease.

Premenstrual syndrome and calcium


Premenstrual syndrome, PMS is often perceived as a trait of hysterical, hypochondriac women. In fact, it is a serious medical condition with a number of unpleasant symptoms:

upset stomach, bloating, constipation or diarrhea
headache
appetite changes or food cravings
joint or muscle pain
tension, irritability, mood swings, or crying spells

trouble concentrating or remembering
breast swelling and tenderness

As simple a measure as higher intakes of calcium and vitamin D might be helpful in case of PMS. (Archives of Internal Medicine, June 2005).
