Key findings
- 1Multiple sweetener sources in one product spread the sugar across the ingredient list; a single commercial granola serving can contain as much sugar as a cookie
- 2Homemade granola (oats, nuts, honey, oil, salt) is a short list of recognizable ingredients; commercial granola often adds several sweeteners, oils, and flavors
- 3Even "healthy" granola brands vary widely, and products from the same brand can range from simple to heavily formulated depending on the variety
Why is Granola Level 3 on average?
Granola was invented in the 1860s as a health food. It is just baked oats and grains. The modern commercial version has diverged substantially. A typical supermarket granola lists rolled oats, sugar, canola oil, rice flour, honey, brown rice syrup, coconut, soy lecithin, natural flavors, and mixed tocopherols. Splitting sugar across several sources (honey, brown rice syrup, cane sugar) puts each individual sweetener lower on the ingredient list (ingredients are listed by weight), so the total sugar is easy to miss. A single serving of commercial granola can contain 12-16g of sugar; comparable to a cookie. The other ingredient to note is "natural flavors," which in granola typically means processed vanilla or fruit-derived flavoring compounds. Products within one brand can vary considerably, from simple oat-and-nut blends to long ingredient lists. In our analysis, granola products average a Processing Score of 5.6, which is Level 3.

How to read a granola label
- 1
Multiple sweetener sources (sugar, honey, brown rice syrup, maple syrup) in one product are used to keep each one lower on the ingredient list; add them up mentally
- 2
"Natural flavors" in granola is typically processed vanilla or fruit flavoring, unnecessary in a product that should taste like oats and nuts
- 3
Canola oil, soybean oil, or palm oil replacing simple butter or coconut oil is a cost-driven substitution
- 4
Compare sugar per serving: homemade granola has 4-6g, commercial brands average 12-16g per serving

Frequently asked questions
Is granola actually healthy?
It depends on the product. Homemade granola with oats, nuts, and minimal honey is a short list of recognizable ingredients. Commercial granola often contains as much sugar per serving as a cookie (12-16g), multiple vegetable oils, and "natural flavors." Check the nutrition label; sugar content is the fastest way to assess quality.
Is Nature Valley granola ultra-processed?
Nature Valley makes many products, and they vary. The crunchy bars list whole grain oats, sugar, canola oil, rice flour, honey, brown rice syrup, and soy lecithin, a longer list than plain oats and honey. Check the specific product, or search Nature Valley to see its own scores.
Is homemade granola better than store-bought?
From a processing standpoint, yes. Homemade granola typically has a handful of ingredients (oats, nuts, oil, honey, salt, and optional spices), while many commercial versions add several sweeteners, oils, and flavors. You also control the sugar and oil quantities. It takes about 30 minutes to make and stores for 2-3 weeks.
What is the least processed granola brand?
Look for brands with under 8 ingredients, a single sweetener source, and no "natural flavors." Some options include simple formulations from Bob's Red Mill, Purely Elizabeth (simpler varieties), and store brands that list just oats, nuts, oil, honey, and salt. Always check the specific product; brands that make simple granola also make heavily processed versions.
