March is National Colorectal Cancer Awareness Month

The goal of the annual National Colorectal Cancer Awareness Month is to make people aware of colorectal cancer and to encourage people to learn more about how to reduce their risk of colorectal cancer (CRC) through regular screening and a healthy lifestyle. The results of the National Health Interview Survey (NHIS) administered to 32,374 adults 18 years of age or older in 2000 showed that colorectal cancer screening is underused [1]. Just over 60% of adults had ever had colorectal cancer testing. Only 44% of men and 37% of women greater than 75 years of age were current for testing. Colorectal cancer screening is very important. If colorectal cancer is allowed to metastasize (meaning to spread to other parts of the body), the 5-year survival rate is less than 10%. However, if colorectal cancer is found early, the 5-year survival rate is greater than 90% [2].

Study Questions Ability of Garlic to Lower LDL Cholesterol

A study published in the Archives of Internal Medicine this week concluded that garlic supplementation does not improve cholesterol profiles in people with moderately high levels of LDL cholesterol (defined here as a fasting plasma LDL cholesterol concentration of 130 to 190 mg/dL, a triglyceride level less than 250 mg/dL and body mass index, calculated as weight in kilograms divided by height in meters squared, of 19 to 30). The study is the first independent, long-term assessment of raw garlic and two popular garlic supplements. Raw garlic (4g/day for 6 months), powdered garlic and aged garlic extract supplement were tested on 192 adults with moderately high levels of LDL cholesterol. None of the garlic forms studied had statistically or clinically significant effects on LDL cholesterol or other plasmid lipid concentrations. The results contradict other recent findings suggesting that garlic may be beneficial in heart health by reducing moderately high levels of LDL cholesterol in adults [1-2].

Vitamin C

Vitamin C is a water-soluble vitamin that is used in many tissues throughout the body. The adrenal gland contains the highest concentration of vitamin C, and the vitamin plays a crucial role in both the adrenal cortex and adrenal medulla [1]. Humans are one of the few species that cannot manufacture the vitamin in the body and must depend on diet or nutritional supplementation as a source of vitamin C. The best sources of vitamin C are fresh fruit (especially in the citrus family, including oranges, lemons, limes and tangerines), strawberries, cantaloupe and currants. Green leafy vegetables, including Brussel sprouts, collard greens, lettuce, cabbage, peas and asparagus, are also good sources.

Caffeine May Prevent Heart Disease in the Elderly

Habitual intake of caffeinated beverages provides protection against the risk of heart disease mortality among the elderly. The study, published in this months issue of The American Journal of Clinical Nutrition, found that participants 65 years of age or older with higher caffeinated beverage intake exhibited lower relative risk of cardiovascular disease and heart disease mortality than did participants with lower caffeinated beverage intake [1].
