Daily sunscreen users are significantly less likely to show signs of skin aging, according to a recent randomized controlled trial performed on people younger than 55 in Australia.  After 4.5 years, daily sunscreen users were 24% less likely to show signs of aging.  More importantly, regular use of sunscreen may decrease risk of skin cancers, including melanomas which can be fatal.  Be aware that spray sunscreens may not be as effective as creams.

Recent observational studies suggest that the drug Metformin, which is used to treat diabetes, may decrease the risk of colorectal cancer in diabetic patients.  Further studies are necessary to confirm this effect.

Another recent study revealed that low Vitamin D levels may exacerbate inflammatory complications in people with Crohns Disease.  Replacing Vitamin D may decrease the frequency for surgery in such patients.
