8 Everyday habits that could shorten your lifespan

Your taste for salt

If you salt everything you eat, you may be jeopardizing your health; too much salty food caused 9.5 percent of the total diet-related deaths, according to a study in the Journal of the American Medical Association. Too much salt can damage the heart or kidneys. The study found that 45.4 percent of all deaths caused by heart disease, stroke, and type 2 diabetes are associated with eating either too much or too little of just 10 food groups.
