One of the best ways to keep your liver healthy is to eat a balanced diet that is low in trans fats and fructose (as in "high fructose corn syrup"). These substances are found in many processed foods, including chips, soda, fried foods, etc., and have both been shown to contribute negatively to liver function.Processed foods also include a host of other chemicals to maintain freshness and appearance, which your liver has to work to filter out. Your best bet for maintaining liver (and overall!) health is to minimize your consumption of prepackaged and processed foods, and prepare food from scratch using fresh ingredients whenever possible.
