LDL, or low density lipoprotein, is known as the "bad" cholesterol. When levels get high, this type of cholesterol can negatively affect the cardiovascular system and lead to a variety of health ailments such as restricted circulation, clogged arteries and heart disease, according to the American Heart Association (AHA). Dietary culprits containing LDL include a variety of animal-based foods and some commercially-prepared foods.
Whole-Fat Dairy
Dairy foods are animal-based products, therefore they contain cholesterol. Dairy foods that are whole-fat contain the highest amounts of LDL, according to the USDA. Whole-fat varieties of sour cream, cheese cake, cottage cheese, cream, butter, hard cheeses and yogurt fall into this category. Whole-fat milk products with high LDL levels include eggnog, evaporated milk and sweetened condensed milk.
High-Fat Protein
Animal-based protein can contain large amounts of LDL. The USDA says red meats such as lamb, beef, pork and veal are high in harmful cholesterol. Certain cuts of meats, such as prime rib and spare ribs, are even higher. Organ meats such as kidney, tripe, heart and liver are rich in LDL. The AHA recommends that you limit consumption of red meats for better heart health.
Egg yolks likewise contain large amounts of LDL, according to the USDA. Eat cholesterol-free egg whites for protein without the cholesterol.
Processed Meats
Processed meats such as bacon, sausage, pepperoni, ham, bologna, hot dogs and salami are all sources of high levels of LDL. In addition to containing cholesterol, these foods contain large amounts of salt and other additives which can adversely affect your health.
Low-Fat Protein
LDL is found in lean protein such as fresh and canned fish, poultry, soy foods and shellfish, says the AHA. The amount of cholesterol, however, is less than amounts in other higher-fat animal products. To decrease your bad cholesterol, the Mayo Clinic recommends you eat three servings of fish weekly.
Commercially Prepared Foods
Commercially-prepared foods are notable for being made with shortening and/or partially hydrogenated oils which can raise LDL levels. According to the AHA and the Mayo Clinic, the following foods can fall into this category: breads, muffins, crackers, pasta, pastries, cakes, cookies, doughnuts, boxed breakfast cereals, snack foods, boxed cake mixes, energy bars, fried foods, deep fried foods, fast foods, restaurant-prepared foods and croissants. Foods made with refined flours instead of whole grains may also raise LDL levels, as well.
