What is the healthiest protein bar out there? A definitive guide

4 min read

According to Consumer Reports, many protein bars on the market contain high amounts of added sugars, making them resemble a glorified candy bar. To confidently answer the question, 'What is the healthiest protein bar out there?', it’s essential to look beyond marketing and scrutinize the label, focusing on whole-food ingredients and low sugar content.

Quick Summary

This guide reveals how to identify a genuinely healthy protein bar by focusing on whole-food ingredients, minimal added sugar, and high-quality protein sources. It examines top contenders like RXBAR, Aloha, and GoMacro to help you make an informed choice based on your dietary needs.

Key Points

  • Check the Ingredients: Prioritize bars with a short, recognizable list of whole-food ingredients like nuts, dates, and seeds, and avoid long lists of artificial fillers.

  • Minimize Added Sugar: Aim for bars with less than 5-8 grams of added sugar, preferring those sweetened with natural sources like fruit or monk fruit over syrups and alcohols.

  • Choose a High-Quality Protein: Opt for bars with complete protein sources such as egg whites, whey isolate, or a blend of plant-based proteins like brown rice and pea.

  • Don't Fear Healthy Fats: Don't shy away from fat content if it comes from healthy sources like nuts and seeds, as these can help with satiety.

  • Match the Bar to Your Goal: Choose a protein bar based on your objective; a light snack bar (10-15g protein) differs from a post-workout recovery bar (20-30g protein).

  • Beware of "Diet" Ingredients: Be cautious of artificial sweeteners and sugar alcohols, which can cause digestive discomfort for some individuals.

Understanding the "Healthy" Protein Bar

The protein bar aisle is a confusing landscape of health claims and flashy packaging. A truly healthy protein bar is defined not just by its protein count, but by the quality of its ingredients, its sugar content, and its overall nutritional balance. Many bars, despite their high protein claims, are little more than processed foods with added sugars and artificial ingredients.

The Importance of Ingredients

When selecting a protein bar, the ingredient list is your most valuable tool. The best options feature a short, recognizable list of whole foods, such as nuts, seeds, dates, and dried fruit. Brands that lead with whole-food ingredients are generally a safer bet.

Look for bars with:

  • A short, simple ingredient list.
  • Whole-food sources like nuts, seeds, and dried fruit.
  • High-quality protein from eggs, whey, or plant-based options like brown rice and pea protein.

Avoid bars with:

  • Excessive added sugars, including high-fructose corn syrup.
  • Artificial sweeteners and sugar alcohols, which can cause digestive issues.
  • Long, unpronounceable ingredient lists and highly processed fibers like chicory root.

Deciphering the Nutritional Panel

The nutritional panel provides a clear snapshot of a bar’s health profile. Beyond just the protein content, savvy consumers should pay close attention to the sugar and fiber numbers. A bar can claim high protein but be loaded with unnecessary sugar, negating its health benefits.

Key Metrics to Monitor:

  • Sugar: Aim for bars with no more than 5–8 grams of total sugar, ideally from natural sources like fruit.
  • Fiber: A good bar should contain at least 3 grams of fiber, which aids digestion and satiety.
  • Protein: For a snack, 10–15 grams is sufficient. For a meal replacement or post-workout fuel, 15–25 grams is ideal.
  • Saturated Fat: Keep saturated fat low, opting for healthy fats from nuts and seeds instead.

Top Contenders for the Healthiest Protein Bar

RXBAR

RXBARs are a perennial favorite among nutritionists for their straightforward, whole-food-based ingredient list. The ingredients are famously listed on the front of the wrapper, typically consisting of a few simple items like egg whites, dates, and nuts. They are free of added sugar and contain over 10 grams of protein and several grams of fiber per bar, making them an excellent all-around choice.

Aloha Bars

For a plant-based option, Aloha bars stand out. They are certified organic, vegan, and free of many top allergens, including soy and gluten. Aloha bars use organic brown rice and pumpkin seed proteins, offering a complete protein source for those on a plant-based diet. They are relatively low in sugar and sweetened with natural ingredients like monk fruit.

GoMacro

Another strong vegan option, GoMacro bars are made with a blend of sprouted brown rice and pea protein. They feature nutritious whole-food ingredients like organic almond butter and rolled oats. While some flavors may be slightly higher in carbs and natural sugars due to ingredients like brown rice syrup, their organic certification and wholesome composition make them a healthy, energy-boosting choice.

How to Choose the Right Bar for You

Your perfect bar depends on your individual health goals. If you're managing blood sugar, look for lower-sugar options. If you're plant-based, vegan bars like Aloha or GoMacro are suitable. If you prioritize minimal processing above all, RXBARs are an excellent fit. Always compare the nutrition labels and ingredient lists carefully to ensure the bar aligns with your dietary needs and isn't a candy bar in disguise. The EWG provides additional insights into the quality of processed foods.

Brands like RXBAR and Aloha consistently top lists for their clean, simple ingredient lists.

Frequently Asked Questions

Not all protein bars are bad, but many are essentially glorified candy bars due to high amounts of added sugar and processed ingredients. A healthy protein bar can be a convenient supplement, but you should always prioritize whole foods when possible.

For weight loss, the best protein bar is one that is high in protein and fiber to promote fullness, and low in added sugar and overall calories (under 200-250 calories). Brands like No Cow offer low-sugar options suitable for weight management.

Bars like RXBAR (sweetened with dates) and Aloha (sweetened with monk fruit) are known for having very low to zero added sugar. Always check the ingredient list for hidden sugars and syrups.

To identify a healthy bar, look for a short, simple ingredient list with whole foods at the top. Check that added sugar is low (under 8g) and fiber content is high (over 3g). Be wary of sugar alcohols and unrecognizable additives.

Homemade protein bars are often a healthier option because you control every ingredient, avoiding processed fillers, excessive sugars, and artificial additives. Many recipes use simple ingredients like oats, nuts, and natural sweeteners.

Good vegan options include Aloha bars and GoMacro bars, which use plant-based protein sources like brown rice, pea, and pumpkin seeds. Ensure the bar contains a complete amino acid profile, often achieved by combining different plant protein sources.

Eating a protein bar daily can be part of a balanced diet, but it should not be your main source of nutrients. Protein bars are best used as a convenient supplement, especially post-workout or during travel, rather than a meal replacement.
