Which is better: Sweet Potato Fries or French Fries?

February 21, 2019

SWEET potato fries have a reputation for being healthier than French fries, but you may wonder whether they’re really better for you. After all, both kinds are usually deep-fried and served in oversized portions.

If you are watching your diet, read on.

Sweet potato fries are slightly higher in calories and carbs but also more nutrient dense than French fries.

The greatest nutrient difference is that French fries have no vitamin A, while sweet potato fries are high in this nutrient. Vitamin A is important for your vision and immune system.

When it comes to cooking method, a 3-ounce (85 grams) serving of baked French fries has 125 calories compared to 150 calories for the same serving of baked sweet potato fries.

A large serving of each kind of fast food fries has as many calories as some people need in an entire meal.

Additionally, the carb and fat content are about doubled if you choose a large rather than a small serving — regardless if they’re French or sweet potato fries.

In short, deep-frying nearly doubles the calories in both French and sweet potato fries compared to baking. When deep-fried, a large serving of either type of fries contains a full meal’s worth of calories.

If you’re avoiding trans fat, you should limit your intake of deep-fried foods, as two studies suggested that small amounts of trans fat may form when oil is repeatedly used in a deep fryer.

In addition to that, acrylamide forms in both types of fries. Acrylamide is classified as “probably carcinogenic” in humans. However, this was based on studies of animals given high doses of the compound.

Acrylamide is a potentially harmful compound discovered in 2002 in cooked, starchy foods — including fries. In fact, fries are one of the major dietary sources of acrylamide.
