The origin of French fries has been disputed for centuries, with Belgium and France both claiming to be their birthplace. In Belgium, it is said that fishermen in the city of Namur began frying thin strips of potatoes in the seventeenth century during the winter months when fish was unavailable. In France, the first appearance of “frites” was recorded in Paris in the eighteenth century, where street vendors sold them along the bridges of the Seine, quickly making them part of the everyday food culture. During the First World War, American soldiers encountered the fried potatoes in Europe and brought them back home, popularising them under the name “French Fries.” Today, Belgium alone has more than 5,000 “friteries,” and since 2014 Belgian fries have been recognised by UNESCO as part of the intangible cultural heritage of humanity.

Key Facts:

  • Possible origin: Belgium or France
  • Seventeenth century: first references in Namur, Belgium
  • Eighteenth century: Paris street vendors
  • Twentieth century: worldwide spread through American soldiers
  • Belgium today: over 5,000 fry shops

Calories and Nutritional Values: What Is Inside French Fries

French fries are energy-dense but poor in nutrients. A portion of one hundred grams contains approximately three hundred to three hundred and twenty calories, which is nearly four times more than the same amount of boiled potatoes. In addition, fries provide thirty-five to forty grams of carbohydrates and fifteen to twenty grams of fat, often from palm oil or hydrogenated oils. Their high salt content can increase the risk of high blood pressure, while acrylamide, a substance formed during frying at high temperatures, is considered potentially carcinogenic. Despite these risks, French fries still provide potassium, a small amount of vitamin C, and can serve as a quick source of energy, especially after physical exertion. However, regular consumption should be limited to avoid health issues.

Nutritional values per 100 g of French fries

  • Calories: 300–320 kcal
  • Fat: 15–20 g
  • Carbohydrates: 35–40 g
  • Protein: 3–4 g
  • Salt: 1–1.5 g

Glycaemic Index: Potatoes versus Sweet Potatoes

The glycaemic index (GI) measures how quickly carbohydrates raise blood sugar levels. French fries are among the highest in this category, with a GI of seventy-five to ninety, which leads to rapid blood sugar fluctuations. Boiled potatoes have a GI of around seventy, while sweet potatoes are much lower at about fifty, making them more suitable for people with diabetes and athletes. Sweet potatoes also contain more beta-carotene, vitamin A, and dietary fibre. Because of these qualities, sweet potatoes are considered a “trendy vegetable” and are increasingly served in restaurants as a healthier alternative to traditional fries.

Who Should Avoid Eating French Fries

French fries are not equally suitable for all groups of people. Individuals with diabetes should avoid them due to their very high glycaemic index. People with heart and circulation problems are at risk because of the combination of fat and salt. Overweight individuals also should be cautious, since fries are calorie-dense and can easily lead to weight gain. For children, fries can become addictive due to their taste and rewarding character, and therefore consumption should be limited. For athletes or individuals with very high energy needs, fries can occasionally be useful as a quick source of carbohydrates, but only in moderation.

Groups at particular risk:

  • People with diabetes (high GI)
  • Individuals with high blood pressure
  • People with overweight or obesity
  • Children with unhealthy eating habits
  • Patients with heart or vascular diseases

Tips: How to Eat French Fries More Healthily

French fries do not always have to be unhealthy, as much depends on preparation and portion size. Instead of deep-frying, it is better to bake them in the oven or prepare them in an air fryer, which reduces fat content by up to seventy percent. Rapeseed oil or olive oil are healthier choices than palm oil. Instead of too much salt, one can use herbs such as rosemary, thyme, or paprika for flavour. A healthy portion is considered to be one hundred to one hundred and fifty grams, ideally combined with vegetables or protein such as fish or chicken. Industrially frozen fries should be avoided whenever possible, since they often contain additives.

Practical tips

  • Use oven or air fryer instead of deep fryer
  • Choose rapeseed oil or olive oil instead of palm oil
  • Season with herbs instead of salt
  • Limit portion size to 100–150 g
  • Combine with vegetables and protein
  • Prefer fresh potatoes over frozen products

Health Benefits and Risks of French Fries

French fries are a food full of contrasts: they can deliver quick energy, but they are also rich in fat, salt, and calories. For some groups of people they may be useful, for others they can be harmful. Athletes may benefit from them as a fast source of carbohydrates after exercise. Children, however, can easily become accustomed to the taste and associate it with reward, increasing the risk of obesity. Senior citizens may find fries an easy source of energy, but they also pose risks for heart and vascular health. For diabetics, fries bring almost no benefits and carry significant risks due to their high glycaemic index.

World French Fries Day on August 20

Every year on August 20 the World French Fries Day is celebrated. The day was established in the early 2000s by associations in Belgium and the United States connected with the potato industry. The idea was to highlight the cultural and economic significance of French fries. In Belgium, fry shops often offer free portions on this day, while in the United States fast-food chains promote special offers and menus. The date was chosen to coincide with the end of the summer potato harvest in Europe and the start of the high consumption season. On social media, the day is marked by photos, recipes, and creative dishes, making it a global event.

Reasons for the celebration:

  • Recognition of culinary tradition
  • Marketing campaigns for restaurants and food industry
  • Symbol of Belgian and French food culture
  • Global social media phenomenon
  • Reminder of the worldwide success of the potato
