Just because you don't smoke doesn't mean you're not doing the same harm to your body. According to Healthy Living, here are 6 UNHEALTHY HABITS THAT ARE AS BAD AS SMOKING:
#1: Sitting all day. According to studies, inactivity is linked to nearly 160,000 cases of breast, colon, prostate, and lung cancer every year, about two-thirds as many cancer cases caused by smoking. Make it a habit to take breaks on-the-move at work, and even make (or buy) a standing workstation so you're less apt to sit all day.
#2: Eating too much meat and cheese. A recent study found that people on high-animal-protein diets during middle age were four times more likely to die of cancer than people on low-protein diets--a mortality risk factor comparable to smoking. The same study found that diets high in plant-based proteins like beans didn't trigger the same increase in cancer rates.
#3: Cooking with natural gas. If you're one of the 34-percent of Americans whose home is equipped with a gas stove, you're getting an added dose of carbon monoxide, nitrogen dioxide, and formaldehyde every time you cook a meal. Those same three contaminants are common in secondhand cigarette smoke.Make sure you use your vent hood.
