However, this widely consumed snack has been the subject of debate regarding whether it should be considered healthy or not. In this article, we will delve into the nutritional aspects of French fries.
We will also explore different cooking methods and the potential health risks associated with them, as well as compare them to the ever-popular sweet potato fries. We will also discuss healthier alternative frying oils and provide tips on making healthier French fries at home.
Brief history and popularity of French fries
It is unsure if French fries originated from France or Belgium. But it is a food item that is loved worldwide. In America alone, the average person eats about 34 pounds of fries each year. Due to their taste, easy accessibility, and crispiness, it is loved by everyone.
Macronutrients are the main nutrients our bodies need. We’re talking about carbohydrates, proteins, and fats here. Below we have described each of these that are present in French fries.
2. Carbohydrates
Carbohydrates are the main source of energy for the body. French fries get most of their calories from carbohydrates, mainly starch. In a normal 100-gram serving of deep-fried French fries, you’d have about 41 grams of carbohydrates.
3. Proteins
Proteins are needed for growth, repair, and maintenance of body tissue. French fries don’t have much protein, though. A 100-gram serving of deep-fried fries holds around 3.4 grams of protein.
4. Fats
Fats give energy, are needed for hormone production, and help your body absorb nutrients. The fat content in French fries depends on how they are cooked. A 100-gram serving of deep-fried French fries has about 17 grams of fat, with 3 grams being saturated fats.
5. Micronutrients
Micronutrients are vitamins and minerals that help keep us healthy. French fries have a few of these to add to their nutritional value.

Why Are Fried Foods Bad for You?
Eating fried foods like French fries can lead to health problems. Below are three main reasons that are responsible for the ill effects on health.
High-Calorie Content
As we’ve seen, French fries are high in calories. This comes from the carbohydrates in the potatoes and the oil absorbed during frying. Taking in high-calorie foods like French fries leads to weight gain and obesity. Over time, this may rise your risk of chronic diseases like heart disease and type 2 diabetes.
High Levels of Trans Fats
The oil used to fry French fries can raise their trans-fat content. Trans fats are made when polyunsaturated fats, often found in vegetable oils, are heated and change their structure. Trans fats have been linked to a higher risk of heart disease and other health issues. Even though law changes have reduced trans fats in fried foods, it’s still wise to limit how much fried food you eat.
Acrylamide Formation
Acrylamide is a harmful chemical formed when foods like French fries are cooked at high temperatures. This chemical may be cancer-causing to humans, meaning it could rise your risk of cancer. Still, we need more human studies to be sure about how acrylamide can cause cancer.
Health Risks Associated with French Fries
Eating French fries often may raise your risk of several health issues. These include heart disease, diabetes, and obesity.
Heart Disease
Frequently opting for French fries may lead to heart disease risk factors. These include high blood pressure and low HDL (“good”) cholesterol levels. Some studies have suggested that eating a lot of fried foods increases your risk of heart disease.
Diabetes
French fries are loaded with carbohydrates, which increase blood sugar levels. A lot of studies found a link between French fries and a higher risk of type 2 diabetes. We need more research to fully understand how French fries may lead to diabetes.
Obesity
French fries are high in calories, which means they can lead to weight gain and obesity if you eat them too much. Being obese puts you at a higher chance of getting chronic diseases, such as diabetes, heart disease, and certain cancers.
Comparing Sweet Potato Fries and French Fries
With sweet potato fries and French fries both being popular, here’s a comparison of their nutritional values and health impacts.
Nutritional Comparison
As we’ve seen, sweet potato fries are slightly higher in calories, carbohydrates, and vitamin A compared to regular French fries. Sweet potato fries do have some extras vitamin A. It’s key to keep in mind though, that both types of fries are high in calories and carbohydrates. This can lead to weight gain and raised blood sugar if you eat them too much.
Acrylamide Formation in Both Types of Fries
Just like with French fries, sweet potato fries can have acrylamide too. It forms when starchy foods like these are cooked at high temperatures, bringing possible health risks. You have to be careful about how you cook and how often you eat both types of fries.
Health Risks and Recommendations
Given their nutritional profiles and the fact that acrylamide can form in both, neither French fries nor sweet potato fries should be eaten in excess. While sweet potato fries have some added nutrients, they come with similar health issues when eaten in large, deep-fried portions. Choose other cooking methods like baking or air frying instead. This can reduce calorie and fat content of your fries. Also always, consume them in moderation.
The Impact of Cooking Methods on French Fries
The way you cook French fries can change their nutritional value and health risks. Let’s look at a few common ways to cook French fries and how they affect their nutrition.
1. Frying
Deep frying is the most common way to make French fries. But it raises calorie and fat content because the fries soak up the frying oil. Plus, very high frying temperatures can lead to formation of acrylamide, a harmful substance linked with possible health risks.
2. Baking
Baking French fries is healthier than deep frying. They soak up less oil this way, leading to less calories and fat. Still, baking at very high temperatures can still lead to acrylamide formation.
3. Air Frying
Air frying is a modern way to “fry” foods with hot air circulation and little to no oil. This cooking method gives a much lower calorie and fat content than deep frying. Plus, air frying might produce less acrylamide than other high-temperature cooking methods. All of that makes air frying a healthier choice overall.
4. Grilling
Grilling can be a healthier way to make French fries as well. It needs only a little oil as it uses lower cooking temperatures. Plus, grilling gives French fries a smoky flavour and crisp outside, a fun twist on traditional French fries. However, we need to watch out for the cooking temperature to avoid excessive charring and acrylamide formation.
If you must fry your French fries, make sure to choose a healthier oil. Also consider other cooking methods to lower health risks.
Healthy Oils
When you want to fry French fries, go for an oil with a high smoke point and low levels of polyunsaturated fats. Some healthier oils for frying are as following.
Olive oil: It has good fats and a high smoke point, good for frying.
Coconut oil: Over 90% of its fats are saturated, which makes it good under heat and a stable oil for frying.
Avocado oil: Like olive oil but with higher smoke point, it’s excellent for deep frying.
Unhealthy Oils
Some oils have high polyunsaturated fat levels, making them prone to forming trans fats under high heat. These include the following.
Canola oil
Soybean oil
Corn oil
Sunflower oil
It’s best to stay away from these when frying French fries.
Alternative Cooking Methods
We have discussed above other ways to cook French fries like baking, air frying, and grilling. They reduce the calorie, fat, and possible acrylamide content of French fries. To get a healthier French fry, try these cooking methods at home.
Making Healthier French Fries
You can make them healthier, while maintaining their taste and feel.
Choosing the Right Potatoes
Going for high-quality potatoes like Russet or Yukon Gold can make your fries turn out better. Plus, if you leave the skin on, you get added fiber and nutrients.
Cutting Techniques and Tricks
To make your fries perfectly crispy, cut them into thin, even strips. This makes sure they all cook the same and get the crunch you want. Also, soaking the cut fries in cold water for 15 minutes or more before cooking can get rid of extra starch and better the texture of the fries.
Seasonings and Spices
Don’t just use salt on your fries. Try a mix of herbs and spices to add more flavour and nutrients to your French fries. Some fine choices are garlic powder, onion powder, paprika, chili powder, or dried herbs like rosemary or thyme.
Conclusion
In conclusion, both French fries and sweet potato fries can harm your health if you eat them too much and cook them by deep frying in unhealthy oil . But you can choose healthier oils, better ways of cooking, and apply better preparation practices to make a healthier French fry.
When eating French fries, the key is moderation. Don’t have them too much and have a well-rounded diet with lots of minimally processed whole foods to keep your health at its best.
