Oat Milk & Blood Sugar | Does it Spike Blood Glucose Levels? (2024)

Oat milk has garnered a lot of attention about its potential impact on blood sugar levels.

We’re here to shed some light on the issue, taking an evidence based approach.

How much sugar is in oat milk?

Oat milk isn't laden with sugar and typically contains 2 to 4 grams per 100ml.

In comparison, dairy milk contains 5 gramsper 100ml.

However, this is notthe whole story, and other factors impactblood sugar response.

The presence of carbohydrates like fibre & starch also play a role, as these are converted to sugarsin the body.

Oat Milk & Blood Sugar | Does it Spike Blood Glucose Levels? (1)

Evidence based approach

To better understand oat milk's impact on blood sugar, we need to look at itsglycemic index (GI) and glycemic load (GL).

These are essentially scoring systems to help classify food based on itsblood sugar response.

Glycemic Index vs. Glycemic Load

Glycemic index (GI) measures how quickly carbohydrate containing foods raise blood sugar.

Glycemic load (GL) takes into account both the quality and quantity of carbohydrates consumed.

Glycemic load is a better indicator as it more accurately represents a food's actual effect on blood sugar levels.

Glycemic index (GI) categories

⬇️ Low GI: 55 or less
➡️ Medium GI: 56 to 69
⬆️ High GI: 70+

Glycemic load (GL) categories

⬇️Low GL: 10 or less
➡️Medium GL: 11 to 19
⬆️High GL: 20+

A lower GI and GL is less likely to spike blood sugar levels

What is the glycemic index (GI) of oat milk?

Oat milk has a glyecmic index (GI) of 61±8, which puts it in the medium category.

This is a similar GI to foods like muesli, couscous and sweet potato.

What is the glycemic load (GL) of oat milk?

✅ Oat milk (100ml) has aglycemic load of4, this puts it in the lowcategory.

✅ Oat milk (250ml) has a glycemic load of 9,this puts it in the lowcategory

This evidence suggests that while oat milk may moderately raise blood sugar levels, its impact is comparable to that of cow's milk and other common foods.

Oat milk vs. fizzy drinks

Somearticles have compared oat milk’s blood sugar response tofizzy drinks.

The evidence suggests this is not true.

A 250ml serving of fizzy drink (e.g. Coca-Cola) has aGL of 17, almost double that of oat milk.

In addition, whilstfizzy drinks are almost exclusively sugar, oat milk contains other nutrients like fibre, protein, fats & vitamins.

What about zero-sugar oat milk?

While some oat milk varieties are marketed as sugar-free, they contain the same level oftotal carbohydrates as regular oat milk .

Consequently, once these carbohydrates are broken down by the body, they still impact blood sugar levels in a similar wayto regular oat milk.

Conclusion

In conclusion, while oat milk does raise blood sugar levels (like all foods), its overall impact on blood sugar levels is considered low/medium based on GL & GI data.

Individuals with specific dietary concerns should always consult healthcare professionals to determine the best choices for their health needs.
