Which Fast Food French Fries Are the Least Healthy?

4 min read

According to a PlushCare study, the regular fries at Five Guys were ranked nearly 50% more unhealthy than other fast-food fries, with alarmingly high calories, fat, and sodium. In this guide, we dive into the nutritional data to determine which fast food french fries are the least healthy based on calories, fat, and sodium content.

Quick Summary

An examination of nutritional data reveals the least healthy fast food french fries, highlighting high-calorie, high-fat, and high-sodium options from various chains. This analysis helps consumers make more informed dietary decisions.

Key Points

  • Five Guys Fries: The large fries from Five Guys are consistently cited as the least healthy due to their massive portion size, leading to extremely high calories, fat, and sodium.

  • Hidden Trans Fat: Some older studies and data show that certain fast-food fries, like those from Jack in the Box, contained significant levels of trans fat, although many chains have reduced this.

  • Sodium Bombs: Fries from chains like Carl's Jr. and Five Guys can contain over 1,300mg of sodium, exceeding half of the daily recommended limit in a single side dish.

  • Portion Size Matters: The unhealthiness of fast food fries is heavily influenced by portion size; a smaller size from a less healthy chain might be better than a huge portion from a 'healthier' one.

  • Moderation is Key: Enjoying fast food fries in moderation and choosing smaller portions are the most effective ways to mitigate their negative health effects.

The Unhealthiest French Fries: A Deeper Look

While the crispiness and saltiness of fast food fries are often hard to resist, the nutritional content can vary dramatically between restaurants. Factors such as portion size, the type of oil used for frying, and the amount of added salt contribute to the overall unhealthiness. A prime example is the fries from Five Guys, which have received widespread attention for their exceptionally high calorie and fat content. However, other contenders like Jack in the Box and Arby's also feature fries with concerning nutritional profiles due to factors like trans fat and high sodium.

To understand which fast food french fries are the least healthy, it's essential to look at the key nutritional culprits: calories, total fat, saturated fat, and sodium. Calories are a measure of energy, and an excessively high number can contribute to weight gain. Both total and saturated fats, especially when from frying, can negatively impact cholesterol levels and heart health. Finally, high sodium intake is linked to increased blood pressure.

Worst Offenders by Nutritional Category

Different fries excel in being unhealthy in different ways. Some are calorie bombs, while others pack an astonishing amount of sodium. Here is a breakdown of some of the worst offenders in each category, based on studies and available nutritional data.

  • Highest in Calories: Five Guys' large fries are notoriously high in calories, with one serving reported to contain over 950 calories due to its enormous portion size. Carl's Jr. Natural Cut fries also feature high calorie counts, even for smaller portions.

  • Highest in Fat: Again, Five Guys large fries lead in this category with a staggering 57 grams of fat. Carl's Jr. Natural Cut fries and Arby's curly fries also contain high amounts of total fat.

  • Highest in Saturated Fat: Five Guys large fries are packed with saturated fat, having 73% more than other fast-food cheeseburgers, which likely extends to their fries as well. Smaller options like Jack in the Box Natural Cut fries can also contain high levels of saturated fat.

  • Highest in Trans Fat: Historically, trans fat was a major concern for fast food fries. While many chains have moved away from partially hydrogenated oils, some smaller outlets or specific products may still contain significant amounts. An older study even highlighted high trans fat levels in fries from certain regions. Jack in the Box's Natural Cut fries have been flagged for their trans fat content in the past.

  • Highest in Sodium: Carl's Jr. Natural Cut fries have been found to contain extremely high levels of sodium, in some cases over 1300mg. Five Guys large fries also pack a massive sodium punch with over 1300mg in a single serving. This represents a significant portion of the recommended daily sodium intake of 2,300mg.

Comparison of High-Profile Unhealthy Fast Food French Fries

Here is a comparison table examining the nutritional profiles of some of the contenders for the least healthy fries. Note that nutritional information can vary based on portion sizes and preparation methods.

Restaurant Item (Large/Regular Size) Calories Total Fat Saturated Fat Sodium
Five Guys Regular/Large Fries ~953+ ~57g+ N/A ~1327mg+
Carl's Jr. Natural Cut Fries (Small) 540 25g N/A 1360mg
Arby's Curly Fries (Small) N/A 20g N/A 791mg
Jack in the Box Natural Cut Fries (Small) N/A 9g 4g sat., 5g trans N/A

Note: Nutritional data may vary based on location, preparation, and specific portion size. Five Guys' larger serving sizes significantly contribute to their high stats.

How These Fries Become Unhealthy

The unhealthiness of these fries stems from several factors beyond just the potatoes themselves. Potatoes are a relatively healthy vegetable, but the preparation methods transform them into calorie and fat-laden sides. The deep-frying process, which involves submerging the potatoes in large vats of oil, significantly increases the fat and calorie content. In the past, partially hydrogenated oils were used, which contributed high levels of trans fat, a major heart health risk. While many chains have moved away from trans fats, the use of other oils still adds large amounts of fat.

Furthermore, the high salt content is a major issue. Sodium is added generously to enhance flavor, but excessive intake is linked to high blood pressure and other cardiovascular problems. The sheer size of portions also plays a crucial role. Chains like Five Guys are known for their generous servings, leading to a much higher intake of calories, fat, and sodium than a typical small or medium order from other chains.

Making Smarter Fast Food Choices

For those who want to enjoy fast-food fries occasionally while being mindful of their health, a few strategies can help:

  1. Opt for a Smaller Portion: This is the easiest way to cut down on calories, fat, and sodium. Most chains offer small sizes that are much more moderate in nutritional content.
  2. Share with a Friend: If you can't resist a larger size, splitting an order with someone else can help manage your intake.
  3. Choose a Lower-Sodium Option: Some chains, like Wendy's or In-N-Out, are known to have lower sodium levels in their fries compared to other restaurants.
  4. Consider Baked or Air-Fried Alternatives: While not available at fast-food restaurants, these options are healthier if you're making fries at home.

Conclusion

When asking which fast food french fries are the least healthy, the answer often points towards chains with notoriously large serving sizes and higher nutritional values, such as Five Guys, Jack in the Box, and Carl's Jr.. While factors like calories, fat, and sodium can be high across the board, the most unhealthy fries are often those that combine large portions with high levels of these nutrients. It is clear that enjoying fast food fries in moderation and being mindful of portion sizes is key to minimizing their negative health impact.
