Over recent years numerous health benefits have been attributed to drinking black coffee.  Now, a recent study has revealed that coffee can protect people from skin cancer which causes growths on sufferers’ skin that vary in degrees of malignancy.

The study looked at people who drank both caffeinated and decaffeinated coffee and found that women who drink over 3 cups of caffeinated coffee each day were 21% less likely to develop a condition known as BCC (basal cell carcinoma) than women who consumed less than a cup of caffeinated coffee each month. Men who drink three or more cups of caffeinated coffee saw a risk reduction of about 10%. The researchers did not find the same correlations in people who drink decaffeinated coffee, suggesting that the protective effect to the skin is likely due to caffeine consumption.

Researchers were quick to note that drinking coffee is no replacement for sunscreen. While caffeine appears to have a protective effect on the skin, it does not compare to the protection offered by a quality sunscreen and ample shade.

A separate study has also found that people with high sodium diets are at greater risk for suffering a stroke.

According to PubMed Health (U.S. National Library of Medicine) a deficiency of vitamin B12 may be linked to dementia in elderly people. A study of 121 people found that participants with lower vitamin B12 levels did worse on cognitive tests and had smaller brain volumes, as shown by MRI scans. Other studies have shown that decreased brain volume is linked to dementia.

Improving the food and drink options that our nation’s children have access to in school is an important step towards reducing the obesity epidemic throughout the country. New reports show that major headway has been made on this front over the last several years in terms of sugary beverages.

In the general population, about 11% of children are bullied. Being bullied is linked to higher levels of depression, loneliness, anxiety, and decreased academic performance.
