French fries contain primarily carbohydrates from the potato (mostly in the form of starch) and fat absorbed during the deep-frying process. For example: a large serving of French fries at McDonald's in the United States is 5.4 ounces (154 grams); nearly all of the 500 calories per serving derive from the 63 g of carbohydrates and the 25 g of fat; a serving also contains 6 g of protein, plus 350 mg of sodium.[32]
Frying French fries in beef tallow, lard, or other animal fats adds saturated fat to the diet. Replacing animal fats with tropical vegetable oils, such as palm oil, simply substitutes one saturated fat for another. Replacing animal fats with partially hydrogenated oil reduces cholesterol but adds trans fat, which has been shown to both raise LDL cholesterol and lower HDL cholesterol. Canola/Rapeseed oil, or sunflower-seed oil are also used, as are mixes of vegetable oils, but beef tallow is generally more popular, especially amongst fast-food outlets that use communal oil baths.[33][34][35] Accordingly, many restaurants now advertise their use of unsaturated oils; for example, both Five Guys and Chick-fil-A advertise that their fries are prepared with peanut oil,[36][37] while In-N-Out advertises that their fries are prepared with vegetable oil.[38]
French fries contain some of the highest levels of acrylamides of any foodstuff, and concerns have been raised about the impact of acrylamides on human health.[39] According to the American Cancer Society it is not clear, as of 2013, whether acrylamide consumption affects people's risk of getting cancer
