By Kathryn Doyle (Reuters Health) – Tapping into the Twitter stream could help researchers understand how healthy people’s lifestyles are and how to target improved public health, according to a recent study. Using geotagged tweets, researchers at the Universities of Utah and Washington were able to build a map of the U.S. by neighborhood, with indicators of how happy and active people in that neighborhood are and what their diets are like. “Overall I think the patterns make sense, more fast food restaurants in the area are correlated with more fast food mentions, but I was surprised that coffee was so highly ranked,” said lead author Quynh C. Nguyen of the University of Utah College of Health in Salt Lake City.

The Daily Meal report on how, just like the body, our hair also benefits from a proper diet. They suggest that certain foods can boost hair health.
