Cardiovascular Disease
Arteriosclerosis, the most well-known disease in which the walls of the arteries become thickened and lose their ability to stretch (commonly referred to as “hardening of the arteries”) is the number one killer in the United States and affects nearly 60 million Americans.
The causes of cardiovascular disease are also well known: heredity, a sedentary lifestyle, poor diet, obesity, smoking and high stress levels, most of which can be altered for improvement and bring about significant reduction in the risk of heart attack. Included among the preventative measures are dietary supplements, which have been found to counter at least some of the risk factors.
Antioxidants
Vitamins A, C and E, grape seed extract and pine bark extract (Pycnogenol), help slow the process of plaque build-up in the arteries by scavenging free radicals that cause oxidation.
The Cambridge Heart Antioxidant Study found that vitamin E effectively reduced heart attack risk in those people in the test who were considered high risk. Those given 400 to 800 IU’s of vitamin E had a 75% lower risk of heart attacks after 18 months of use.
The New England Journal of Medicine concluded from a study of 40,000 men, that those who took at least 100 IU’s of vitamin E per day for 24 months lowered their risk of heart attacks by almost 40%.
Other nutritional supplements known to fight cardiovascular disease are Co-Q10, garlic, soy, L-carnitine, and B vitamins.
Cancer
Many cancers are significantly influenced by lifestyle and environmental factors. Smoking, stress, obesity, pollutants, carcinogens, poor exercise and deficiencies in nutrients all play a role in the risk of getting some cancers.
Antioxidants
Numerous studies suggest that antioxidants as a whole prevent oxidative damage to cells and to DNA. In some cases, antioxidants are being used for cancer treatment.
Carotenoids
Beta-carotene has shown anticancer capabilities in a number of clinical trials. Lycopene, found in tomatoes, has been the subject of research relating to its role in reducing the risk of certain cancers. One study suggested that eating 10 servings per week of tomato-based foods reduced the risk of developing prostate cancer by nearly 45%.
Selenium
A 1997 study reported in The Journal of the American Medical Association showed that selenium was responsible for a 50% decrease in cancer deaths: 63% fewer cases of prostate cancer, 58% fewer cases of colon cancer, and 46% fewer incidents of lung cancer.
Osteoarthritis
More than 40 million Americans suffer from osteoarthritis and 80% of them are over 50. Many of them believe that stiffness, loss of joint function, acute localized pain, tenderness and swelling or bony hardness are just a part of getting old.
The cumulative effects of years of “wear and tear” do cause degenerative changes by causing stress to the collagen matrix of cartilage. Ibuprofen is most often taken to relieve symptoms of osteoarthritis, but long-term healing requires new dietary therapy.
Glucosamine
Supplemental glucosamine works by being absorbed directly into joint cartilage where it is distributed to the joint tissues. It is then incorporated into the connective tissue matrix of cartilage, ligaments and tendons. The recommended dosage for glucosamine is about 1,500 mg daily. Glucosamine and chondroitin sulfate may protect existing cartilage from premature breakdown by inhibiting certain enzymes that destroy cartilage or prevent the transport of nutrients.
Osteoporosis
Calcium and vitamin D intake has been reported to reduce the risk of hip fractures by almost 20%. The FDA recognizes calcium as a preventative for osteoporosis. The primary source of both vitamin D and calcium is cow’s milk. Given that 75% of Americans are lactose intolerant, dietary supplementation makes sense.
If you are planning to take any dietary supplement for a particular ailment, always check with your doctor.
