Phytic Acid-The Mineral Reducer

Bean Talk
Listen to this post

You may have heard of phytic acid as a “mineral reducer,” and this is very true. Eating raw nuts, seeds, grains, and legumes can prevent your body from absorbing some of the minerals from your food. 

But phytic acid has another side too.  It has some health benefits.

Do you soak or sprout your nuts, seeds, grains and legumes?

Is it to help improve their digestibility? To help increase their nutrition?

Perhaps, it’s to reduce phytic acid?

Phytic acid is naturally present in most nuts, seeds, grains and legumes; it is the plant’s storage form of the mineral phosphorus and is used as energy when the plant starts to grow.

The highest levels of phytic acid are found in rice bran, wheat bran, wheat germ, almonds, and walnuts.

Phytic acid and minerals

You may have heard of phytic acid being referred to as an “anti-nutrient”.

Phytic acid binds to the minerals iron, zinc, and calcium preventing them from being fully absorbed when eaten; this is why phytic acid is known as a “mineral reducer.”

FUN FACT: Phytic acid’s effects only apply to mineral-containing foods in the current meal. Once digested, there is no mineral reduction on any future meals and there is no impact to the minerals your body has already absorbed.

Phytic acid’s health benefits

Phytic acid isn’t all bad – it has some health benefits too.

It can act as an antioxidant. It can also help reduce your risk of kidney stones, heart disease, and even some cancers.

Because it loves minerals (which are metals), phytic acid in your gut can also bind to any heavy metals (the metals we don’t want too much of) that may have hitched a ride with your food.

How to reduce phytic acid

As you can see, phytic acid shouldn’t be a huge concern, unless your main foods at most meals are nuts, seeds, grains, and legumes. Because many of these are nutritious foods, you probably don’t want to cut all of them completely out of your diet.

Considering both the good and bad properties of phytic acid, you may still want to reduce how much you consume. Maybe you want to increase your mineral intake. If so, here are two popular methods to naturally reduce phytic acid:

  • Soaking – Place nuts, seeds, grains or legumes in a bowl, cover with water and leave overnight. Then drain the water and rinse before eating or preparing.
  • Sprouting – After soaking, draining, and rinsing, place damp nuts, seeds, grains or legumes into a container that’s exposed to the air (like a mason jar with a mesh lid). Every 8 hours or so, re-rinse them and drain the water. Continue doing this for a few days until you see sprouts peeking out.

Tip on soaking beans. As a bean (legume) lover I prefer to make my bean dishes from “scratch”. Meaning, I purchase dry beans and soak them overnight in a bowl with plenty of water. This is key. In my experience, if the beans are above the water line when you check them in the morning the chances are they won’t soften during the cooking process. The beans have to be well covered with plenty of fresh water during the overnight soak which also speeds up the cooking process. I also believe everyone could benefit from eating more beans!!

Why do soaking and sprouting help reduce phytic acid in certain foods? It is because being wet is a “sign” to leave their dormant (dry) state and start a new life.  Enzymes activated during soaking and sprouting deactivate phytic acid to use its energy and stored minerals for the plant as it begins to grow.

Conclusion

Phytic acid has a bad rap as a mineral reducer. It’s found in nuts, seeds, grains, and legumes. Yes, it most definitely prevents absorption of critical minerals like iron, zinc, and calcium, if they’re in your gut at the same time. Phytic acid in food can become a health concern if you are deficient in these minerals, or if your diet is largely based on nuts, seeds, grains, and legumes.

But, if you eat a varied diet, then phytic acid shouldn’t be as much of a concern. In fact, phytic acid does have some health benefits.

If you want to reduce it in your food, you can soak or sprout your nuts, seeds, grains, and legumes.

Recipe (soaked almonds): Almond Vanilla Latte Smoothie

Serves 1

¼ cup almonds, soaked overnight & rinsed

½ cup coconut milk

½ cup strong coffee, cold (or chai tea if you prefer)

½ banana, frozen

1 tsp vanilla extract

Add all ingredients to a blender and blend on high until almonds are smooth.

Add ice, if desired

Serve & enjoy!

Tip: By using soaked almonds, they tend to blend up smoother than hard and crunchy dry almonds do.

Raw vs. Cooked – Which Contains More Vitamins and Minerals?

Let’s finally put an end to the debate of raw vs. cooked.

Of course, in the grand scheme of a well-balanced, nutrient-dense, varied, whole foods diet, the cooked vs. raw debate isn’t that critical for most people.

Where this can become a consideration is for vitamin and mineral deficiencies (or “insufficiencies”). These may be due to digestion or absorption issues, or avoidance of certain foods (due to allergies, intolerances, or choice).

And I’ll tell you that the answer isn’t as simple as “raw is always better” or “cooked is always better.”  As with most nutrition science, it depends on several factors. Some vitamins are destroyed in cooking, while others become easier to absorb (a.k.a. more “bioavailable”).

With the Metabolic Balance® program, both raw and cooked foods are part of each and every individual meal plan. This guarantees that the maximum nutrition is derived from the foods. The plan will explain which vegetables are eaten raw and which are cooked, taking the guess work out. Learn more here. Or visit the page on Metabolic Balance® here

Here is the skinny on vitamins and minerals in raw foods versus cooked foods. You have the option of reading on or for my friends who prefer audio there’s a 5 minute recording right here.

Raw Versus Cooked Foods

 Foods to eat raw

As a general rule, water soluble nutrients, like vitamin C and the B vitamins, found mostly in fruits and vegetables, are best eaten raw.

The reason why is two-fold.

First, when these nutrients are heated, they tend to degrade;  this is from any heat, be it steaming, boiling, roasting, or frying. Vitamin C and the B vitamins are a bit more “delicate” and susceptible to heat than many other nutrients.

Of course, the obvious way to combat these nutrient losses is to eat foods high vitamin C and B vitamins in their raw form (like in an awesome salad) or to cook them for as short a time as possible (like quickly steaming or blanching).

Fun fact: Raw spinach can contain three times the amount of vitamin C as cooked spinach.

The second reason why foods high in vitamin C and the B vitamins are best eaten raw is that they’re “water soluble.”  So, guess where the vitamins go when they’re cooked in water?  Yes, they’re dissolved right into the water;  this is particularly true for fruits and veggies that are boiled and poached but even for foods that are steamed as well.

Of course, if you’re a savvy health nut, you’ll probably keep that liquid to use in your next soup or sauce to preserve those nutrients that are left after cooking. Just don’t overheat it or you may lose what you were aiming to keep.

But, how much loss are we talking about?  Well, of course, it ranges but can go from as low as 15%, up to over 50%.

In short, the water soluble vitamins like vitamin C and the B vitamins degrade with heat and some of what’s left over after they’re heated dissolves into the cooking water. So be sure to cook your fruits and veggies as little as possible, and keep that cooking water to use in your next recipe.

Soaking nuts and seeds

Regarding raw nuts and seeds, it may be beneficial to soak them. Soaking nuts and seeds (for several hours at room temperature) allows some of the minerals to become “unlocked” from their chemical structure, so they’re more absorbable.

Foods to eat cooked

Cooking certain orange and red “beta-carotene rich” veggies (e.g. tomatoes, carrots, & sweet potatoes) can help make this pre-vitamin A compound more absorbable.

Fun fact: One study found that absorption of beta-carotene was 6.5 times greater in stir-fried carrots than in raw carrots!

Of course, eating your fat-soluble vitamins with a bit of fat will help you to absorb more of them, so that’s one factor to consider.

One vegetable that’s best eaten both raw and cooked

Spinach!

And I’m not just saying this to get everyone to eat it any way possible (although, I would love for this to happen…unless you’re allergic, or sensitive to the oxalates in spinach of course).

Spinach contains so many beneficial compounds that it’s great eaten both raw and cooked.

Eating raw spinach preserves the water-soluble vitamins C & the B vitamins.

Eating spinach cooked allows the pre-vitamin A, as well as some of the minerals like iron to be better absorbed. Not to mention how much spinach reduces in size when it’s cooked, so it’s easier to eat way more cooked spinach than raw spinach.

Conclusion:

The old nutrition philosophy of making sure you get a lot of nutrient-dense whole foods into your diet holds true. Feel free to mix up how you eat them, whether you prefer raw or cooked just make sure you eat them.
