Key Findings

  • Muesli is inherently less processed than granola because it skips baking, added oils, and binding syrups entirely
  • The original 1900s Swiss recipe is nearly identical to what quality brands sell today — raw oats, fruit, and nuts
  • Sweetened or chocolate-chip muesli undermines the simplicity that defines the product — always check for added sugars

Why Is Muesli Level 1?

Muesli was developed in the early 1900s by Swiss physician Maximilian Bircher-Benner as a health food for hospital patients. The original recipe was raw oats soaked overnight in water with grated apple, lemon juice, and nuts. Modern muesli stays close to this formula: rolled oats, raisins, dried fruit, nuts, seeds, and sometimes coconut flakes. The critical distinction from granola is what is absent — muesli is not baked or toasted, contains no added oils, and uses no binding syrups. This means there is no Maillard reaction (the browning that occurs during baking), no added fats, and no caramelized sugar holding clusters together. The processing is essentially just mixing raw ingredients. Where muesli goes wrong is in sweetened varieties that add sugar, chocolate chips, or yogurt-coated pieces — these push a Level 1 product toward Level 3. Tropical or dessert-style muesli can be as processed as the granola it claims to replace.

    Compare to granola: muesli should have no added oils and no baked clusters

  4. 4

    Bob's Red Mill, Alpen (original), and similar brands keep ingredient lists under 10 items

Frequently Asked Questions

Is muesli healthier than granola?

From a processing standpoint, traditional muesli (Level 1-2) is less processed than commercial granola (Level 3-4). Muesli has no added oils, no baking step, and typically less sugar. Nutritionally, both are oat-based — the difference is what gets added during manufacturing.

What is the difference between muesli and granola?

Muesli is raw mixed ingredients (oats, fruits, nuts, seeds) with no baking or added oils. Granola is baked with oil and sweetener to create toasted clusters. This makes muesli Level 1-2 and granola Level 3-4 despite similar base ingredients.

Do you eat muesli hot or cold?

Both. Traditional Bircher muesli is soaked overnight in milk or yogurt and eaten cold. You can also cook it briefly like oatmeal. Neither preparation method changes the processing level — the food is the same, only the serving temperature differs.

Is Alpen muesli ultra-processed?

Alpen Original muesli lists rolled oats, wheat flakes, raisins, hazelnuts, almonds, and sugar — Level 2 with minimal processing. The sugar is the main additive. Alpen varieties with chocolate or yogurt pieces are more processed (Level 3). Check the specific product.
