Are deep fried Mars bars healthy? The surprising truth

5 min read

A 2014 study from the University of Glasgow revealed that eating a deep fried Mars bar could modestly reduce blood flow to the brain in men within 90 minutes. This study, along with a deep fried Mars bar's staggering calorie count and high fat content, reveals why this snack is far from healthy.

Quick Summary

This article explores the question of whether deep fried Mars bars are healthy, breaking down the nutritional issues associated with this indulgence. It details the high calorie and fat content, the presence of harmful trans fats, and the risks linked to deep-fried foods in general, such as an increased risk of chronic diseases like heart disease and diabetes. Alternatives and healthier cooking methods are also covered.

Key Points

  • High in Calories and Fat: The deep frying process significantly increases the calorie and fat content, with fat being the densest calorie source.

  • Contains Harmful Trans Fats: Reusing oil for deep frying can create trans fats, which are linked to heart disease and other chronic illnesses.

  • Associated with Chronic Diseases: Frequent consumption of deep fried foods is associated with an increased risk of obesity, type 2 diabetes, and cardiovascular disease.

  • May Contain Toxic Compounds: High-temperature frying can produce chemicals like acrylamide, a potential carcinogen.

  • Best for Occasional Indulgence Only: A deep fried Mars bar is a poor nutritional choice and should only be considered a rare treat, not a regular dietary item.

  • Healthier Alternatives Exist: For a sweet treat, options like baked fruit or dark chocolate are far better for one's health.

Deep Fried Mars Bars: Deconstructing a Scottish Indulgence

The deep fried Mars bar is a legendary Scottish takeaway, born from a dare in a Stonehaven chip shop in 1992. It is made by dipping a chocolate bar in batter and deep frying it until golden. While a novelty item, its reputation as an emblem of a poor diet is well-founded, and its health implications are a subject of frequent discussion.

The Mars Bar: A Look at the Core Ingredients

Before it is deep fried, a standard Mars bar is already high in sugar and fat. The primary ingredients include sugar, glucose syrup, milk chocolate, and palm fat. A single bar is not a source of significant nutritional value but provides a quick hit of energy from simple carbohydrates and fats. When battered and fried, this nutritional profile changes dramatically for the worse, amplifying the existing unhealthy components.

The Impact of Deep Frying on Nutrition

Deep frying involves submerging food in hot oil, which fundamentally changes its composition. The process causes the food to absorb a significant amount of oil, drastically increasing its fat and calorie count. For a deep fried Mars bar, a product already high in sugar is transformed into a caloric bomb. According to one nutrition breakdown, a single deep fried Mars bar can pack upwards of 640 calories, with 37% of its energy coming from fat.

Here is a list of ways deep frying damages the nutritional profile:

  • Massive Calorie Increase: The absorption of fat from the oil adds a substantial number of calories. Fat contains more than twice the calories of carbohydrates or protein by weight.
  • Introduction of Harmful Fats: The process can create trans fats, especially if the oil is reused. Trans fats are difficult for the body to process and are linked to heart disease, diabetes, and obesity.
  • Formation of Toxic Compounds: High-temperature cooking, such as deep frying, can lead to the formation of harmful chemicals like acrylamide in some foods, which have been linked to cancer in animal studies.
  • Loss of Nutrients: While a Mars bar is not nutritionally dense to begin with, the deep frying process can destroy some vitamins and amino acids.

Chronic Disease Risk and Deep Fried Foods

Regular consumption of deep fried foods is linked to a higher risk of several chronic health conditions. The combination of high calories, saturated and trans fats, and sodium can lead to significant health problems. Research has established a clear correlation between frequent fried food intake and these diseases.

Fried Food vs. Unfried Food: A Comparison

Feature Plain Mars Bar Deep Fried Mars Bar Baked Apple Pie Air-Fried Apple Slices
Calories ~225 kcal 640+ kcal ~250 kcal (per slice) ~100 kcal (per serving)
Fat Content ~8.1g ~28g ~12g (per slice) <1g

Cooking Method No cooking Deep frying Baking Air frying/Baking
Health Impact Occasional treat Very unhealthy indulgence Occasional treat Healthy snack alternative

Healthier Alternatives and Moderation

For those seeking a healthier way to indulge their sweet tooth, there are numerous alternatives that provide flavor without the health risks of deep frying. Baked or air-fried fruit, like bananas or apples, can offer a warm, satisfying dessert. Desserts made with dark chocolate, which contains antioxidants, can be a more mindful choice.

Conclusion: A Cautionary Treat

In short, the answer to "are deep fried Mars bars healthy?" is a definitive no. The addition of batter and deep frying oil to an already calorie-dense, sugary snack multiplies its unhealthy attributes. While enjoying such a novelty as a very rare treat on a special occasion might be acceptable for some, regular consumption significantly increases the risk of obesity, cardiovascular disease, and other chronic illnesses. The deep fried Mars bar is a cultural curiosity, not a dietary staple.

For individuals concerned about their heart health, dieticians and healthcare professionals consistently recommend limiting the intake of fried foods. Prioritizing baked or air-fried options and enjoying desserts that utilize healthier fats and less sugar is a much safer path to wellness.

Frequently Asked Questions

The deep fried Mars bar originated in 1992 at The Carron Fish Bar in Stonehaven, Scotland, born from a playful dare with local schoolchildren.

While you can technically 'air fry' a Mars bar, which uses less oil, the underlying product is still extremely high in sugar and fat, so it will not be truly 'healthy'.

All deep fried foods, by nature of the cooking process, absorb oil and become high in fat and calories. The degree of 'bad' depends on the food itself and the oil used, but they are generally less healthy than other cooking methods.

When deep fried, the chocolate, caramel, and nougat inside the Mars bar melt and become gooey, creating a very rich and decadent texture.

Mars has publicly distanced itself from the deep fried version of its product, noting that it promotes a healthy, active lifestyle and that deep frying counters efforts to reduce saturated fat.

A deep fried Mars bar has no discernible nutritional benefits. The high calorie, sugar, and fat content significantly outweigh any minimal nutrients it might contain.

Healthier sweet treat alternatives include baked fruit with a light drizzle of honey, dark chocolate in moderation, or homemade fruit-based desserts.
