Strive to eat a non-processed diet. If your diet is made up of fresh fruits and veggies, plain meats, whole grains, homemade baked goods and beverages such as water, plain tea and coffee and pure fruit juices, no one will have the opportunity to sneak HFCS into your food and drink. When you do use processed foods, read the labels closely and choose those that do not contain HFCS, and while you're at it, avoid hydrogenated oils as well.
