Oat milk is a liquid vegetable drink. It is suitable for those who carry out a vegan diet and people with lactose intolerance.

Tips when making oat milk at home

  • Oat milk can become gelatinous if mixed excessively.
  • It can also get the wrong texture if you overheat it. If you are going to heat it, cook it over medium-low heat for no more than 3-4 minutes.
  • If you don’t have a milk bag, you can use a clean, fine cloth.
  • If you prefer flavored oat milk, you can add cinnamon, vanilla, and sweeteners, for example, stevia.
  • Homemade oat milk will last about five days in the refrigerator.
  • If you buy gluten-free oatmeal, you can make it suitable for celiacs at home.

Nutritional properties of homemade oat milk

Oat milk has excellent nutritional properties. Compared to other plant milk (such as coconut milk ), it has a better amino acid profile, a slightly higher amount of protein, and higher plant fiber content. In addition, it does not contain saturated fat or trans fat.

Making oat milk at home allows you to choose ingredients to flavor it ( cinnamon, vanilla, etc.) and avoid additives found in commercial products. If you use certified gluten-free oats, you will ensure that it is also suitable for celiacs.

However, homemade oat milk does not have as many micronutrients (vitamins and minerals) as the fortified options you can find in stores.

If in your diet you do not receive enough vitamins, for example, B12 in vegans. So, you’d better go for commercially fortified oat milk.

On the other hand, some brands have added sugar, gluten as a thickener, and preservatives. To get the last word on which one has better properties than others, you should read the label and adapt it to your diet.

For example, you can see the nutritional properties of an unfortified boxed unsweetened oat milk; these are very similar to those of a homemade one. The dietary properties of homemade oat milk are:

  • Calories: 110 Kcal
  • Total carbohydrates: 15 g
  • Sugars: 0g
  • Fibra vegetal: 3 g
  • Net carbohydrates: 12 g
  • Proteins: 3 g
  • Fat: 5 g
  • Saturated fat: 0 g
  • Cholesterol: 0 g

Is oat milk good for your health? – Profits

Research on oatmeal and milk made from this cereal confirms that they can have several health benefits. In particular, it is helpful for those with food allergies and high cholesterol levels. The benefits of oat milk are:

  1. Provides vitamins for group B

Both homemade and store-bought oat milk are sources of B vitamins. However, only those you can buy in stores are fortified with B12. If you are looking for a source of vitamin B12 for your diet, make sure it is reinforced.

  1. It can lower bad cholesterol (LDL)

Oat milk is high in beta-glucans, a type of soluble dietary fiber. Studies have confirmed that consuming 3 grams of these molecules per day has health benefits. This is the equivalent of 2 1/2 cups of oat milk per day.

The benefits of consuming 3 grams of beta-glucans per day are: lower bad cholesterol (LDL) in the blood, improved the working mechanics of the pancreas, intestine, and natural microflora. (1,2)

  1. Suitable for vegans

Oat milk is an excellent substitute for those who do not consume animal products. Since it is made with only oatmeal and water, it is suitable for vegans. In addition, it is also ideal for people with allergies to nuts or soy.

  1. It can be suitable for celiacs.

Naturally, oats are gluten-free, but they are usually processed in the same factories as other cereals, contaminating the oats. If you want to make oat milk at home suitable for celiacs, make sure you buy certified gluten-free oatmeal brands.

  1. Contains no saturated or trans fats

In lesser amounts, cow’s milk has saturated fat and trans fat. According to the WHO, avoiding this type of fat is essential to achieving a healthy diet. Oat milk contains only healthy plant fats. (3)


Oat milk is a healthy liquid drink suitable for vegans allergic to lactose and nuts.

To make oat milk at home, you only need oatmeal, water, a blender, and a cheesecloth or cloth to filter it.

The health benefits of oat milk have been confirmed by science, apparently due to a particular type of fiber, beta-glucans.

Fortified oat milk is higher in vitamins and minerals than homemade. If you are vegan and looking for a source of vitamin B12, it is better to buy it.
