Is Oat Milk or Almond Milk Healthier?

šŸ“… Updated February 2026ā±ļø 4 min readNEW
⚔

TL;DR

Neither is a perfect health food, but unsweetened almond milk wins for weight management and blood sugar control. Oat milk contains up to 16 grams of carbohydrates per cup and acts like liquid sugar in the body. If you want a creamy texture without the glucose spike, choose a clean-ingredient almond milk.

šŸ”‘ Key Findings

1

Oat milk has a moderate-to-high Glycemic Index (GI) of around 60, meaning it spikes blood sugar rapidly.

2

Unsweetened almond milk contains just 30-40 calories and 1 gram of carbs per cup.

3

Commercial oat milk processing breaks starches down into maltose, a sugar with an incredibly high glycemic load.

4

Both milks frequently contain inflammatory seed oils, emulsifiers, and synthetic gums to mimic dairy texture.

The Short Answer

Unsweetened almond milk is the healthier choice for most people. It has significantly fewer calories and carbohydrates than oat milk, making it drastically better for blood sugar stability and weight management.

Oat milk isn't a health food; it's liquid carbohydrates. One cup of oat milk packs up to 120 calories and 16 grams of carbs, while almond milk sits at just 30 calories and 1 gram of carbs.

Why This Matters

Oat milk processing creates a massive blood sugar problem. Enzymes break down the oat starches into maltose, a type of sugar that spikes blood glucose faster than table sugar. Oat Milk Blood Sugar

Commercial almond milk is essentially just almond-flavored water. Most mainstream brands contain less than 2% actual almonds, meaning you aren't getting the protein or healthy fats found in whole nuts. Is Plant Milk Healthy

Both plant milks are heavily processed industrial foods. To mimic the mouthfeel of dairy milk, manufacturers pump them full of seed oils, emulsifiers, and synthetic vitamins. Oil In Oat Milk

What's Actually In Plant Milk

  • Maltose — The hidden sugar in oat milk. Even "unsweetened" oat milk contains this fast-digesting carb created during the enzymatic breakdown of oats. Oat Milk Blood Sugar
  • Rapeseed or Canola Oil — The secret to oat milk's creaminess. Barista blends use cheap seed oils to create micro-foam, introducing inflammatory omega-6 fats into your morning coffee. Oil In Oat Milk
  • Gellan Gum and Locust Bean Gum — Thickeners used to prevent separation. They are common in almond milk and can cause bloating, gas, and irritation in sensitive digestive systems. Gums Plant Milk Bad
  • Carrageenan — A highly controversial thickener linked to gut inflammation. Though less common now, it still sneaks into some mainstream plant milks. Is Carrageenan Safe

What to Look For

Green Flags:

  • Three ingredients or less — The cleanest milks only use water, nuts/oats, and salt.
  • Organic certification — Crucial for avoiding toxic herbicides. Conventional oats are heavily sprayed with glyphosate (Roundup) right before harvest.

Red Flags:

  • Barista blends — Industry code for "pumped full of seed oils." This is exactly how they make plant milk froth and stretch like dairy milk. Best Barista Oat Milk
  • Added sugars — A recipe for a mid-morning energy crash. Sweetened versions can contain up to 10 grams of added cane sugar per single cup.

The Bottom Line

1. Choose almond milk for blood sugar. It won't cause the rapid glucose spikes and subsequent energy crashes associated with oat milk.

2. Read the ingredient label. Avoid any carton with added oils, gums, or vague natural flavors.

3. Buy organic. This is absolutely non-negotiable for oat milk due to widespread glyphosate contamination.
