Plants and Their Anti-Nutrients

author avatar Dr. Eric Berg 03/27/2024

Anti-nutrients in plants is a topic that often stirs up confusion and concern among health-conscious individuals.

The term alludes to certain substances found commonly in various plant-based sustenance, which can meddle with our body's capacity to ingest fundamental supplements.

Learn about certain anti-nutrients in plants and the effects they can have on your body.

Understanding Plant Defense Mechanisms

Plants have evolved to develop various defense mechanisms in the realm of survival. These defenses include the production of phytoestrogens, phytic acid, lectins, oxalates, and saponins.

While these compounds act as protective shields for plants against predators or environmental stressors, they can pose health challenges when consumed excessively by humans.

Phytoestrogens and Their Effects on Insects

Phytoestrogen is a plant-derived compound that mirrors estrogen's effects on animals' bodies. Plants primarily produce them as responses to insect infestation or fungal attacks.

This disruption also applies to human consumption through food products like soybeans or flax seeds, which contain high levels of isoflavones (phytoestrogen). This could lead to hormonal imbalances if consumed excessively.

Phytate levels

Phytic Acid as a Chelator

The mineral-chelating property inherent in phytic acid, often found in cereal grains such as black gram protein, aids in storing essential nutrients within plants but may hinder nutrient absorption during the digestion process upon excessive intake.

Reducing antinutrients from foods showed health benefits; soaking significantly reduced phytate content, thus enhancing the availability of free mineral contents while improving overall digestibility.

Lectins Causing Leaky Gut Syndrome

Lectins are proteins abundantly present across various types of plant foods, including wheat and beans, where their role extends beyond cell-cell interactions, serving protective functions against pests and pathogens alike.

Ingesting excessive amounts of lectins may cause intestinal damage, resulting in leaky gut syndrome, allowing toxins to enter the bloodstream and leading to chronic diseases over time - thus underscoring the need for limited consumption, especially among vulnerable individuals.

The Role of Anti-Nutrients in Human Health

While vital for plant survival, anti-nutrients can somewhat impact human health when consumed excessively. These compounds interfere with nutrient absorption and may lead to various health issues.

Impact of Excessive Consumption of Phytoestrogens

Phytoestrogens, which act like hormones in our bodies, are present in various plant-based foods such as soybeans, flaxseeds, and whole grains.

When these substances mimic estrogen hormones within our bodies at high levels, they could potentially disrupt hormonal balance.

Research suggests that excessive intake might result in fertility problems or an increased risk for certain cancers due to this hormone-like activity.

Yet, moderate consumption has been linked to advantageous outcomes such as the alleviation of menopause symptoms and a decrease in the chances of cardiovascular illness.

Potential Risks Associated With High Intake Of Phytic Acid

In plants, phytic acid serves as a phosphorus store but poses challenges when ingested by humans because it possesses a mineral-chelating property.

This means it binds minerals like iron, zinc, and calcium, making them unavailable during digestion, thus inhibiting their absorption into our system.

Studies demonstrate that excessive amounts might contribute to deficiencies, especially among those following vegetarian or vegan diets, where primary sources are often rich in phytate content.

Fortunately, soaking food grains significantly reduces phytate content, improving their nutritional value.

How Lectin Sensitivity Affects Digestion

Lectins, proteins present across a wide range from legumes through cereal crops, are made edible via cooking methods explicitly designed to reduce these antinutritional factors.

Despite precautions, some individuals still experience sensitivity leading to digestive distress, including bloating and even leaky gut syndrome over time due to prolonged exposure periods involved here, respectively.

Specific Conditions Related to Anti-Nutrient Consumption and Their Remedies

The presence of anti-nutrients in our diet can cause various health issues, such as SIBO-related bloating, autoimmune diseases, and kidney stones.

Fortunately, several effective remedies involve dietary changes and other treatments that may help alleviate symptoms associated with these conditions.

Dealing with Bloat through Change in Vegetable Consumption

Bloating is often linked to consuming certain vegetables rich in complex carbohydrates that are difficult for our digestive tract to break down completely. This leads to fermentation within the gut, producing gas as a by-product.

It would be best to alter your vegetable intake habits to manage this issue effectively. For instance, cooked vegetables are easier to digest than raw ones since cooking breaks down some fibers, making them more digestible.

Also, consider rotating different types of veggies regularly so as not to consume too much of any single type at once.

Managing SIBO through Diet Modification

Small Intestinal Bacterial Overgrowth (SIBO), characterized by excessive bacteria growth within the small intestine, could be exacerbated by the intake of antinutrients like lectins and phytic acid found predominantly in grains and legumes, respectively.

Hard-to-digest substances feed harmful gut bacteria, causing bloating and other digestive problems.

Try limiting food products rich in such aforementioned 'anti-nutrients' while simultaneously increasing those enriched with essential amino acids and others conducive to healthy digestion.

Tackling Autoimmune Disorders by Eliminating Harmful Foods

The impact of diet on autoimmune disorders is crucial, as specific substances found in certain foods can cause the immune system to attack the body's own cells, causing inflammation mistakenly.

Various plant-based foods contain anti-nutrients that may trigger these responses and worsen existing conditions.

Dry Lips and Anti-Nutrients in Food

If you've found yourself asking why your lips are so dry, it's worth considering the potential influence of anti-nutrients in your diet.

Dry lips can sometimes be linked to nutrient deficiencies caused by anti-nutrients, compounds found in certain foods that can interfere with the absorption of essential nutrients.

These anti-nutrients, such as phytates and oxalates, can hinder the absorption of minerals like zinc and iron, which play a crucial role in maintaining healthy skin, including the skin on your lips.

To promote lip health and overall well-being, it's essential to balance consuming nutrient-rich foods and being mindful of sources of anti-nutrients in your diet.


Grasping the purpose of anti-nutrients in foodstuffs is critical to maximizing your well-being and nourishment. Plants use these substances as defense mechanisms, producing compounds like phytoestrogens, phytic acid, lectins, oxalates, and saponins.

While they protect the plant kingdom from predators, their impact on human health can be significant when consumed excessively.

We also explored strategies for mitigating their effects - soaking seeds and nuts overnight or rotating vegetables regularly are some effective methods.

People with specific conditions such as SIBO or autoimmune diseases may need to modify their diet further to manage symptoms related to high intake levels of certain anti-nutrients.
