Because Brazil nuts have an exceptionally high concentration of phytic acid, measuring 2% to 6% in their hulls, they might interfere with the absorption of some nutrients like iron, zinc, calcium, and magnesium.
Are Brazil nuts high in phytic acid?
Phytic acid is found in plant seeds, nuts, legumes, and grains. The amount contained in these foods is highly variable.
Phytic acid in foods.
| Food | Amount of phytic acid |
|---|---|
| beans | 0.6–2.4% |
| Brazil nuts | 0.3–6.3% |
| hazelnuts | 0.2–0.9% |
| lentils | 0.3–1.5% |
How do you remove phytic acid from Brazil nuts?

Is it necessary to soak Brazil nuts?
Magnesium is an essential mineral needed for calcium absorption as well as aiding relaxation, and is found in good levels in Brazil nuts. Proper preparation by soaking your nuts and grains overnight neutralises the phytic acid making them more easily digested — plus it increases the nutritional value!
Which nut has the least phytic acid?
However, macadamia nuts show significantly low levels of phytic acid and subsequently contain the least amount of phytic acid of all the nuts.
How do you neutralize phytic acid?
Milling is the most commonly used method to remove phytic acid from grains. This technique removes the phytic acid but also has major disadvantages as it also removes major parts of minerals and dietary fibers. Soaking is widely applied and most important method in germination and fermentation process of cereals.
Does lemon juice neutralize phytic acid?
Phytic acid can be neutralized in as little as 7 hours when soaked in water with the addition of a small amount of an acidic medium such as vinegar or lemon juice. Soaking also helps to break down gluten, a hard-to-digest protein found in grains such as wheat, spelt, rye and barley.
How long should you soak Brazil nuts?
Soaking: Place the Brazil nuts and salt in a large bowl along with the water. Leave them on the counter for 8-12 hours. Cover with a clean cloth and lay it over the bowl, this allows the contents of the bowl to breathe.
Does vitamin C neutralize phytic acid?
Vitamin C appears strong enough to overcome phytic acid. In one study, adding 50 mg of vitamin C counteracted the phytic acid load of a meal. In another study, 80 mg of ascorbic acid (vitamin C) counteracted 25 mg of phytic acid.
Do Brazil nuts raise your blood sugar?
The dietary fiber in Brazil nuts can also help to lower blood cholesterol levels, reducing the risk of heart disease and stroke. Some studies show that the selenium in Brazil nuts can help to lower insulin levels and boost insulin sensitivity, improving blood sugar levels in people with type 2 diabetes.
Does roasting nuts reduce phytic acid?
Roasting Nuts
Roasting reduces the phytate content of nuts, although there’s not much research available regarding specifics of how the nutritional content of nuts changes when you roast them. It is also thought to improve their digest-ability.
How do you soak nuts to remove phytic acid?
How do I soak raw nuts and seeds?
- Measure out 4 cups of raw, unsalted, organic nuts/seeds into a medium sized bowl.
- Cover with filtered water so that nuts are submerged.
- Add 1-2 tablespoons unrefined salt.
- Allow to stand covered on the counter for about 7 hours, or overnight.
Is oatmeal high in phytic acid?
Soaking activates an enzyme in the oats called phytase that naturally breaks down phytic acid. However, unlike other grains, oats do not have a significant amount of the phytase enzyme. So, you may want to consider adding a complement grain or yeast to further reduce the level of phytic acid.
Does coffee have phytic acid?
Coffee beans also contain phytic acid. The chart in Figure 1 shows the variability of phytate levels in various common foods as a percentage of dry weight. Phytate levels in terms of milligrams per hundred grams are shown in Figure 2.
Does cooking oatmeal destroy phytic acid?
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.
Are sweet potatoes high in phytates?
In addition to the presence of many beneficial nutrients which may be obtained by the consumption of sweet potato, studies in our laboratory have shown that sweet potato has a high phytic acid to zinc ratio of 18:1 even after cooking compared to other tuber crops.
Does phytic acid cause inflammation?
Phytic acid may influence the inflammatory process through its anti-oxidant properties. The antioxidant properties of phytic acid are based on its ability to prevent iron-mediated free radical formation, and the suppression of lipid peroxidation [33,34].
What enzyme breaks down phytic acid?
phytase
Dephytinization is the process of breaking down phytic acid to increase the bioavailability of certain minerals. This is done using phytase, an enzyme that makes minerals available for absorption. Interestingly, phytase naturally occurs in raw plants.
Do avocados have phytic acid?
Additionally, avocados also contain lower levels of phytates and oxalates compared to the most popular fiber sources such as cereal fibers, vegetables, and legumes, thus minimizing loss of calcium and other key essential minerals due to binding by such substances [77].
Are potatoes high in phytic acid?
Previous studies have reported food plants that contain high phytate levels (0.08-2.1 g/100g FW), including wheat grain, maize, rice, cassava, potato, peanut, plantain, and lentils (Lazarte et al., 2015).
Is peanut butter high in phytic acid?
Despite its high phytate content, peanut butter can fit into a balanced diet. Its potential health benefits outweigh the risks, says Minchen. As long as you’re not allergic to peanuts, you can enjoy this treat every now and then. Like other protein-rich foods, it may increase satiety and speed up your metabolism.
