While no candy is a health food, some options provide slightly more nutritional substance than others. A registered dietitian recently noted that Peanut M&M's are considered the 'healthiest' Halloween candy option due to the protein and fiber from the nuts. But with so many flavors available, what's the healthiest M&M variety for your next treat?

Quick Summary

A nutritional comparison of popular M&M's flavors reveals that versions containing peanuts or dark chocolate often have a slight edge. Key differences in calories, sugar, fat, and protein influence which option is the better choice for a balanced diet.

Key Points

Peanut Varieties Offer More: Peanut and Dark Chocolate Peanut M&M's contain protein and fiber from the nuts, which provides more substance than sugar-only options.
Dark Chocolate has an Edge: Dark Chocolate Peanut M&M's have a higher cocoa content and less sugar than milk chocolate versions, offering more antioxidants.
Crispy & Caramel are Pure Sugar: Crispy and Caramel M&M's offer little to no protein or fiber, making them less satiating and primarily a source of sugar.
Moderation is Most Important: Portion control is the single most significant health factor when eating any candy, regardless of the variety chosen.
Focus on Alternatives for Health: For everyday snacking, truly healthy alternatives like plain nuts, seeds, or high-cacao dark chocolate are superior to any M&M's product.

What Defines a 'Healthy' M&M?

Before diving into a direct comparison, it's important to set expectations. M&M's, like all candies, are an indulgence and not a significant source of nutrition. The 'healthiest' option is the one that offers the most nutritional value or the least-harmful ingredients within the context of a treat. This typically means looking for options that contain some fiber, protein, or healthy fats, or are lower in added sugar.

The Role of Nuts

Varieties like Peanut and Almond M&M's benefit from including nuts. Nuts are a source of protein, fiber, and healthy fats, which can help promote feelings of fullness and potentially slow the absorption of sugar into the bloodstream. This means that a small serving of a nut-based M&M might be more satisfying and lead to consuming fewer calories overall compared to a simple sugar candy.

Dark Chocolate vs. Milk Chocolate

Another key factor is the type of chocolate. Dark chocolate, especially with a high cocoa content (70% or higher), contains more antioxidants than milk chocolate. These antioxidants, called flavonoids, have anti-inflammatory and other beneficial properties. While the amount of dark chocolate in a small serving of M&M's is minimal, Dark Chocolate M&M's still contain less sugar and more cocoa solids than their classic milk chocolate counterparts.

Nutritional Comparison Table

To provide a clear picture, here is a comparison of the nutrition facts for a standard serving size (around 40g) of several popular M&M's varieties. Note: Nutritional values can vary slightly between regions and product sizes.


Variety	Serving Size (approx.)	Calories	Total Fat	Saturated Fat	Protein	Sugar	Fiber
Milk Chocolate	40g	193	9g	5g	2g	26g	1g
Peanut	40g	203	11g	5g	4g	22g	2g
Peanut Butter	46g	240	13g	7g	5g	23g	1g
Dark Chocolate Peanut	42g	210	12g	6g	4g	21g	2g
Crispy	36g	175	7g	4.5g	1g	21g	0g
Caramel	40g	190	8g	5g	2g	23g	0g

The Verdict: Which M&M is the Healthiest?

Based on the nutritional data, the Dark Chocolate Peanut M&M's and the standard Peanut M&M's are the most viable options for a slightly healthier choice. Here's why:

Peanut Protein and Fiber: Both varieties contain peanuts, which offer a small amount of protein and fiber that can contribute to a feeling of fullness and help moderate the sugar rush. This makes them a more satisfying treat than purely sugar-based varieties like Crispy or Caramel.
Dark Chocolate Benefits: The dark chocolate version provides the added benefit of a higher cocoa content and fewer grams of sugar than the classic milk chocolate peanut variety. This gives it a slight edge in terms of antioxidants.
Moderation is Key: Regardless of the variety chosen, the most important aspect of responsible snacking is moderation. Portion size is a critical factor, and enjoying a smaller treat is always the best approach. A single serving of even the "healthiest" option is still a significant source of added sugar and fat.

Other Factors to Consider

When making your choice, other factors besides macronutrients can influence your decision. For example:

Ingredients: Some consumers prefer candies with fewer or more natural ingredients. While M&M's use artificial dyes and flavorings, some alternative brands on the market, such as Unreal, offer similar products with vegetable-based colors and less sugar.
Added Sugar: The amount of added sugar is a key concern for many. Even within the M&M's family, the sugar content can vary significantly. Comparing the sugar grams per serving is a smart way to find a lower-sugar treat.
Satiety: The combination of protein, fat, and fiber in peanut-based M&M's can help you feel more satisfied, making you less likely to overeat. This is a behavioral health benefit that pure sugar candies don't offer as effectively.

The Final Conclusion

When a craving for M&M's strikes, reaching for the Dark Chocolate Peanut M&M's or regular Peanut M&M's is a slightly more nutritionally sound choice than other flavors like Classic Milk Chocolate, Crispy, or Caramel. The inclusion of peanuts provides a small boost of protein and fiber, and the dark chocolate version further reduces the sugar content while adding antioxidants. However, the overarching truth remains that candy is an occasional treat, and portion control is the most impactful decision you can make for your health. For those seeking truly healthy alternatives, options like high-cacao dark chocolate or fruit-and-nut combinations are better for regular snacking. Ultimately, enjoy your treat mindfully and in moderation.

Frequently Asked Questions

No M&M variety is considered a truly 'healthy' food. They are all treats high in sugar and fat with minimal nutritional value. The term 'healthiest' is relative and refers to options that offer slightly more nutritional substance, like protein from peanuts, compared to others.

Peanut M&M's are often cited as the healthiest because the peanuts provide a small amount of protein, fiber, and healthy fats. This combination can help you feel more full and satisfied, making you less likely to overeat compared to purely sugar-based candies.

Dark chocolate M&M's, particularly the peanut variety, contain more cocoa solids and antioxidants than their milk chocolate counterparts. While the amount is small, this gives them a slight nutritional edge. The health benefits of dark chocolate are most significant when consuming chocolate with a higher cocoa percentage (70%+).

Based on a standard serving size, Crispy M&M's often have the fewest calories due to the puffed rice center, which is less calorie-dense than nuts or a caramel filling. However, they also lack the protein and fiber found in nut-based varieties.

The key to enjoying M&M's healthily is moderation. No matter which variety you choose, it's a treat. Sticking to a small, single-serving portion and enjoying it mindfully is the best approach to minimize negative health impacts.
