Chocolate, coffee, and red wine have been deemed “superfoods” for the super effects they have on our health, but some benefits are more accurate than others. After spending months reviewing scientific studies, reviews, and meta-analyses (and ranking categories such as number of studies and popularity using tools like Google Scholar), Information is Beautiful turned the research into an interactive infographic to display the validity of health claims about popular superfoods. Here are some of the most interesting findings.
Honey’s great for healing — it kills infections when applied directly to wounds and reduces inflammation — but there’s no strong evidence it relieves coughing .
Prunes really do help keep us regular, but the dried fruit may not actually prevent chronic diseases including cancer and heart disease .
While coffee can improve asthma conditions, more research is needed to prove if it lowers the risk for depression, dementia, and Alzheimer’s.
Promising evidence shows dark chocolate may lower blood pressure, but that doesn't necessarily mean it'll lower the risk for heart disease, stroke, or diabetes .
Oysters are an excellent source of zinc, but there's no solid research stating that they boost sex drive.
10. Fish Oil/Omega-3 Fatty Acids
Fish oil/Omega-3s were most strongly supported by trials for cancer prevention, but evidence they benefit cognitive function is less conclusive .
Here at Greatist, we put research and studies at the forefront, and this infographic is the perfect example of how science is always rapidly evolving.
