The benefits of nuts on cardiovascular health have been known for some time, but an analysis of multiple trials found particular health benefits of walnuts. The data showed that people who ate a diet enriched with walnuts had lower cholesterol than those who ate a standard diet.
There is evidence that there are beneficial effects of alcohol in moderate amounts, but an analysis of drinkers found that the current guidelines in the US might be associated with a slightly shorter life expectancy for some people.
The results of online searches on health topics vary greatly from state to state, even though common conditions occur everywhere.
A chemical produced during the process of roasting coffee is considered potentially harmful, but the amounts are small, and the potential health benefits of drinking coffee are likely to outweigh any potential risk.
Anyone who needs a knee or hip replacement wants to know if it will be permanent, or if the replacement will need to be replaced at some point.

An observational study found that people diagnosed with stress-related disorders were more likely to develop an autoimmune disease, but was unable to provide proof of a directly causal relationship.
An analysis of women receiving a routine screening mammogram suggests that the benefits of this testing are not as significant as previously believed. However, a woman’s decision to get tested or not depends on many factors and it is worth a conversation with her doctor about the risks and benefits of screening.
