Alcohol would be the worst choice, followed by regular and decaffeinated coffees, diet soda, regular soda, black tea, and non-organic whole milk. These drinks contain toxic chemicals that cause stress on the liver, and deplete vitamins and minerals in the body that are used for detoxification. They also cause the blood to become acidic, which causes other health problems like liver disease. Fat intake should come mostly from raw fats such as raw vegetables, like avocado, and raw seed fats, like olive oil or sesame oil. Fats in their purest state are most efficient in cell repair and hormone production.
Fats are very heat sensitive.
Whenever fats are heated to a high temperature they become free radicals, which are toxic and harmful to the liver and blood. If you have to cook a fat, do so at the lowest temperature possible. Olive oil is considered the most stable for cooking. If the oil turns brown or smokes, then it has been damaged and is now loaded with free radicals that are harmful to the liver and blood. This is why using low temperatures is so important.
