3. The fridge
Although your refrigerator helps preserve food longer, it could also be encouraging the development of disease in your body. Because it houses perishable items, the fridge commonly sees the growth of E. coli, listeria, and salmonella, all of which can cause serious gastrointestinal disease. These bacteria thrive if you do not take proper care of your fridge, and this goes beyond only cleaning it once a year or so. Overstuffing it, keeping it too warm, placing raw meat on top shelves (which allows juices to drip onto food items below), pouring unused milk back into the carton — all of these turn your fridge into the optimal breeding ground for harmful bacteria. Keep your tummy healthy by cleaning your refrigerator once a month with soap and hot water, separating your fruits from your vegetables, and moving foods that are sensitive to bacterial growth (like eggs) to the back of the fridge where it’s colder.
