Most people realize by now that low-density lipoprotein, or LDL, is the “bad” kind of cholesterol, but why is it bad? Arteriosclerosis - popularly called "hardening of the arteries" - is thought to result from the oxidation of LDL. It appears that LDL cholesterol combined with oxygen it is more likely to adhere to arterial walls.
The good news is that antioxidant foods appear to slow or prevent this oxidation process. An Australian study on the effects of chile pepper (Capsicum spp., also sometimes called chili pepper) found that the rate of lipoprotein oxidation was 10.4 percent lower when the study's 27 adult subjects were consuming chiles regularly compared to when they ate no chiles.
Capsaicin, the active ingredient in chile peppers, has also been shown to inhibit bacterial growth, increase energy expenditure, and relieve skin allergies and neurological disorders when used topically. So if you love chile peppers, as I do, don't hold back - enjoy them on a regular basis.

Vitamin D and Diabetes
We need vitamin D for strong bones - it facilitates the absorption of calcium - and a growing body of evidence suggests that it lowers the risk of multiple sclerosis and several types of cancer. New research indicates that vitamin D also may protect against type 2 diabetes. The findings come from a 17-year follow-up of about 4,000 men and women in Finland. Over the study period, 187 of them developed type 2 diabetes. The researchers found that the risk among those with the highest blood levels of vitamin D was 40 percent lower than it was among those with the lowest blood levels of "D." The risk was calculated after adjusting for age, sex and the time of year when the blood was drawn; levels of vitamin D are highest during the months when sun exposure - which prompts synthesis of the vitamin - is greatest. You also can get vitamin D from fish and, the researchers noted that in their study, the diabetes risk was in line with earlier findings that a high intake of fish oil reduces the risk of coronary artery disease. The study was published in the October 2007 issue of Diabetes Care.

It's Christmas-Tree Allergy Time
If you find yourself sneezing or bothered by watery eyes and an itchy, runny nose at this time of year, the problem could be your Christmas tree. Doctors once thought that pollen clinging to the trees was to blame, but a Connecticut allergist recently reported on an experiment that suggests otherwise. He put a live Christmas tree inside an apartment and took air samples for two weeks. At first, mold spore counts were only slightly higher than the normal range, 500 to 700 spores per cubic meter of air, but within two weeks they spiraled to 5,000 spores per cubic meter. Mold forms when trees decay. The longer the tree is up, the worse the potential to exacerbate allergy symptoms, particularly among people with asthma and those prone to sinus infections. The findings were presented at the annual meeting of the American College of Allergy, Asthma & Immunology in November 2007. You can get rid of the symptoms easily: just take down the tree … or buy a fake.
