Are protein bars healthy? A fair look at what is inside

Protein bars are not automatically healthy. Nutrition researchers at Tufts describe many of them as ultra processed and high in sugar, and note that most people likely do not need the extra protein. A good bar is one with an honest ingredient list, limited sugar, and a protein source you can name.

The six checks

• Added sugar: look for the words added sugar, syrups, and sugar alcohols
• Protein per serving: read the grams on the nutrition table
• Protein source: pea, rice, soy or whey
• Ingredient length: shorter is usually easier to judge
• Texture: whole ingredients such as nuts and grains tell you what is real
• Allergens: nuts, soy and gluten differ between brands

What 'ultra processed' really means

The term describes foods made with ingredients and processes not found in home kitchens, such as protein isolates, emulsifiers and flavourings. It is a spectrum, not a switch. Extracting protein from peas is processing, and we say so openly. The useful question is whether the whole recipe is simple and understandable.

How the AORAH 36% stacks up

The 36% Protein lists seven ingredients on the pack: cacao butter, plant protein (pea), crunchy millets, quinoa, hazelnut, natural vanilla extract and sea salt. It has 6.8 g of protein per 50 g and no added sugar. It is still a chocolate bar, a considered snack and not a meal.

Read the ingredients, not the adjectives.

A better question than 'is it healthy?'

Ask whether it is something you would eat anyway. If a bar is genuinely delicious, you will eat it slowly and enjoy it, which is a better outcome than a worthy bar left in a drawer. Compare it with other options in our guide to healthy chocolate and the chocolate facts.
