Trying to eat healthily often leads to multiple points of confusion in this day and age. Every week we hear about a new “superfood,” or maybe that a previous one isn’t as great as once touted to be.

I strongly advocate listening to new advice, and giving it a try for yourself to see how your body reacts. Allow your body to tell you what’s right and whats wrong in each equation.

So, how do you reduce phytic acid in overnight oats? The best way to eliminate phytic acid in oats is to soak them in liquid, with a splash of apple cider vinegar or lemon juice, for 12 to 16 hours before eating.

However, we are all different! While one person may benefit from a low-carb diet, the other person may experience an adverse reaction.

Even though I love to eat overnight oats every day, that does not always guarantee the same circ*mstance for others.

If you curl up in pain the minute you go near soaked oats, then phytic acid may be one of the oat side effects to blame. Here are a few ways you can improve your digestion of this enzyme without having to restrict yourself too much.

What are overnight oats?

Make overnight oats by soaking oats in liquid following a basic overnight oats ratio of 1½:1 liquid to oats. The soaking is usually done overnight so that the phytic acid dissipates, and then no cook oatmeal is ready to eat the very next day.

Steel cut oats, rolled oats or quick oats are generally available in every market, however they are not the only kinds. Rolled oats are best type for overnight oats, but there are recipes using the other kinds too.

Overnight oats can be made with water, almond milk, oat milk or really any liquid you enjoy

I have been dedicated to exploring a wide range of overnight oats recipes, which allowed me to play around with no cook oatmeal flavors like blueberry muffin, caffè mocha and pumpkin spice latte.

With all the wild combinations available, I generally stick to the same basic formula: old-fashioned oats, chia seeds, dairy free milk, nut butter, berries and a pinch of salt.

When I add nuts, chia seeds, or protein powder, I always increase the liquid to oats ratio to 2:1, otherwise I follow the basic overnight oats ratio. This is because the mix-ins will absorb additional moisture so the ratio needs to compensate.

Are overnight oats good for you?

In relation to the phrase, “you are what you eat,” well yes overnight oats are healthy. The fact of the matter resides in the overall benefits of oats, and the vessel of transport for nutritious superfood ingredients and toppings.

Oats offer healthy fats, plant based protein and both soluble and insoluble fiber. Beta-glucan is a soluble fiber present in oats that has been proven to be good for weight loss.

When comparing overnight oats to cooked oatmeal, it seems that soaking oats is more nutrias because they have had a chance to ferment. The fermentation process allows the growth of beneficial bacteria that help the gut microflora present in the digestive tract.

With all the health goals, it must noted that overnight oats is a vehicle that often includes a wide range of additions. Stay away from adding excess sugar, extremely high fats and overly process ingredients, then the meal prep will remain wholesome, hearty and packed with nutrition.

Phytic acid is a unique natural substance found in many cereal grains, oil seeds, legumes and nuts.

Phytic acid reduces the ability for your body to absorb iron, zinc and calcium, which can inevitably lead to mineral deficiencies if left unchecked [1].

As a result, phytic acid is often referred to as an anti-nutrient.

Although it can potentially impair the absorption rate of essential minerals, this is often not the case for those following a balanced diet.

There are several preparation methods that allow us to successful reduce the amount of phytic acid in foods, including oats. Cooking is one of the easiest ways to reduce the about of phytic acid in oats, but that defeats the point of overnight oats.

Soaking, sprouting and fermentation are the most common methods to reduce phytic acid without cooking [2].

Best way to reduce phytic acid in overnight oats

Even though you soak the oats while making overnight oats, you are still consuming the soaking water that contains the phytic acid.

After doing more research about the soaking oats, I realized that there are two ways to supercharge your soaked oats andsuccessfully neutralize or reduce the phytic acid in your soaked oats.

Soak and drain: This is the most efficient way to remove the phytic acid. Add sufficient amount of water to allow your oats to soak overnight without fully absorbing all of the liquid. The next day, drain the remaining liquid and rinse the oats before mixing with your favorite add-ins and toppings.

Neutralize the phytic acid: Soaking oats overnight with a splash of fresh lemon juice or apple cider vinegar will help to neutralize the phytic acid within the soaking liquid. As a result, you can consume the soaked oats and your body is able to activate the digesting enzymes that absorb the available minerals.

If you want to make your breakfast porridge truly healthy, then soak oats overnight in either water with a pinch of salt and drain the liquid the next day, or make a bircher muesli containing oats soaked overnight in natural yogurt, grated apple and lemon juice.

The next day, add oatmeal toppings like honey, cinnamon, nuts, dried fruits, coconut and berries.
