Per 100g, Snickers provides 422 calories with 18.5g of protein, 13.2g of fat, and 57.3g of carbs. The protein content is notable for a candy bar, coming from the peanuts and nougat, but this comes alongside 33g of sugar per 100g and significant saturated fat (4.8g per 100g). The USDA data for this entry shows very high micronutrient values (calcium 953mg, iron 14.7mg, folate 1236mcg per 100g), which reflects a nutrient-fortified version. For a standard Snickers bar, the most useful data is the serving size: 55g bar at 232 calories with 10.2g protein, 18.2g sugar, and 1.5g fiber. Snickers is one of the most popular candy bars in the US, and for active people who want a sweet treat, it is more nutritious than many other candy options due to the peanut content.

Health Benefits of Snickers Bars
Snickers has a higher protein content than most candy bars due to its peanut and nougat filling. The 10.2g of protein per bar is actually a meaningful protein contribution compared to other sweets like gummy candy or hard candy, which have essentially no protein. The peanuts also add some healthy fats and micronutrients.
From a practical perspective, Snickers can serve as a quick energy source in high-energy situations. The combination of sugar for fast energy and fat for sustained energy makes it a historically popular choice among athletes and active people. The caloric density (232 cal per 55g bar) makes it a convenient way to add calories during a hard bulk.
For most fitness goals, Snickers is best treated as an occasional treat rather than a regular food. The 33g of sugar per 100g and significant saturated fat content make it a poor daily food choice. However, one bar as part of a balanced diet does not derail progress. The key is fitting it into your daily calorie budget rather than treating it as off-limits entirely, which can create a restriction-binge cycle.
Dietary Considerations
Standard Snickers bars contain milk, eggs, peanuts, and soy, making them unsuitable for vegans, those with dairy or egg allergies, and those with peanut allergies. Snickers is not gluten-free (may contain wheat depending on the variety). Not keto-friendly at 57.3g of carbs per 100g. For weight loss, Snickers should be an occasional indulgence accounted for in daily calories rather than a regular part of the diet.
