The Characteristics of Antinutrients
Antinutrients are compounds that interfere with the absorption of substances in the intestine and they can be natural or synthetic. Furthermore, they’ve been the focus of research in recent years because several foods and beverages we regularly consume contain them.
These elements are present in nature and they’re not harmful to the body. What are the most common ones? What should you know about them? Continue reading to find out.
Main antinutrients in foods and beverages
Antinutrients baffle people who try to stick to a healthy diet. However, the benefits of foods containing these substances outweigh any possible negative effects. At least according to an article published by the Harvard School of Public Health.
These are types of polyphenols that hinder the absorption of some proteins or iron. They’re present in grapes, which are rich in resveratrol, and often have a bitter taste. However, they contain antioxidant properties that are essential for health despite their iron-chelating power.
Moreover, their consumption seems to help prevent cardiovascular disease, according to an article published in the British Journal of Pharmacology. This is why you must include these substances in your diet.
You must also ensure a regular intake of iron and vitamin C, through the inclusion of other foods, so as not to experience complications related to anemia.
The intake of large amounts of tannins could be a risk factor for vegans. This is because vegetable iron has a lower bioavailability than animal iron in itself. Thus, it’s necessary to monitor the intake of this mineral in diets without animal products.
In short, it’s best to increase the intake of vitamin C in this type of diet, as well as to space out foods abundant in vegetable iron from those containing tannins.
This is mainly present in seeds, grains, nuts, and certain legumes. Its consumption might have an impact on the absorption of zinc, iron, and calcium. In addition, it can inhibit some digestive enzymes linked to proteolysis.
For now, human trials are still lacking in order to provide solid evidence in this regard. It’s clear that this substance has positive health implications though.

This substance is present in certain green leafy vegetables. It binds calcium and can reduce its absorption. In addition, it can also interfere with other minerals such as iron or magnesium.
As if this wasn’t enough, its excessive intake might promote kidney stones. However, these are actually due to dehydration and, possibly, to a certain genetic conditioning factor.
In addition, biodiversity in the intestinal microbiota can significantly reduce the risk of this type of ailment. Bacteria of the genus Lactobacillus are responsible for preventing the formation of stones by degrading oxalate salts, according to a review published in Microbial Pathogenesis.
Excessive fiber intake may interfere with the absorption of some nutrients from the diet. It delays glucose absorption and partially blocks cholesterol absorption when ingested in normal amounts. However, it may interfere with protein absorption in higher proportions.
This substance is necessary for any diet though. This is because it improves the management of the satiety mechanism in addition to reducing the problems associated with intestinal transit.
Moreover, its consumption is related to the selective growth of the microbiota from fermentation processes. Cardiovascular risk also decreases when the dietary fiber intake is adequate.
