Here are lists of the most unhealthy food in the world. Super-Sweet Cereals Breakfast cereals are commonly loaded with sugar. The Environmental Working Group found that 10 of the most sugary cereals were between 41 percent and 56 percent sugar by weight. A study published in 2010 in the “Journal of the American Medical Association” found that high added sugar consumption was correlated with higher low-density lipoprotein -- LDL, or "bad" cholesterol -- and lower high-density lipoprotein -- HDL, or the "good" cholesterol. Sugary Coffee Drinks Many people are accustomed to starting their day with high-calorie coffee drinks. A 20-ounce coffee drink from one major chain has almost 600 calories and 15 grams of saturated fat. That's 30 percent of your calorie allowance and almost your entire daily limit of saturated fat for a typical 2,000-calorie diet. Canned Soup Canned soup is notorious for being very high in sodium. A single cup of one brand of condensed soup contains a whopping 760 milligrams of sodium. A can contains 2 1/2 servings, so if you consume one can of this soup, you're ingesting 1,900 milligrams of sodium. The daily recommended limit is 2,300 milligrams, or 1,500 milligrams if you are 51 or older, or you have certain risk factors. Margarine Bars Each tablespoon of one brand of margarine contains 2 1/2 grams of trans fat, which is more than your entire 2-gram recommended daily limit. The Center for Science in the Public Interest notes that margarine in tubs is actually less likely to contain trans fat. Avoid products with the words “hydrogenated oil” on the ingredient labels. High-Calorie Soda A can of soda typically has between 30 to 40 grams of sugar and almost no nutritional value. A 2007 paper published in the "American Journal of Public Health" notes that there is a significant positive correlation between soft drink consumption and type-2 diabetes. Processed Meats In a 2010 study, Harvard School of Public Health researchers found that consuming processed deli meat, sausage and bacon increased the risk of heart disease by 42 percent and type-2 diabetes by 19 percent. In addition, processed meats are high in sodium -- a single slice of bologna can contain from 310 to 480 milligrams. Ice Cream Ice cream is offensive in many categories, with high levels of fat, saturated fat, sugar and calories. MedlinePlus notes that due to its high saturated fat content, ice cream is one food that can contribute to heart disease. Frozen French Fries French fries and tater tots are sometimes side dishes for breakfast, lunch and dinner in the many American homes. A single 3-ounce serving of french fries can contain more than 500 milligrams of sodium, along with 8 to 11 grams of fat and nearly 200 calories.
