How Food Affects Your Health: The Role of Dietary Lectins

Dr. Steven Gundry is an inventor, best-selling author, and world renowned doctor. Dr. Gundry discusses lectins & autoimmunity.

When it comes to health, the food eaten has the most significant impact of all. And that means avoiding dietary lectins as much as possible. Lectins are a plant toxin that can have adverse effects on a person’s health. Eliminating lectins from your diet can have a big effect on how you feel. If you’re interested in learning more about dietary lectins and how they can affect your health, keep reading!

Dietary lectins often cause autoimmune diseases. Lectins are a protein that can bind to cells in the body and cause inflammation. The lectin-free diet is becoming more popular as people learn about the potential health benefits. A lectin-free diet means you should eliminate and avoid foods that contain lectins, including grains, legumes, and some fruits and vegetables.

The Theory of Why Elevated Adiponectin Is Associated with Lectin Sensitivity

Obesity is a proinflammatory state, and lectins can worsen inflammation. So it’s no surprise that obesity and lectin sensitivity are often linked.

But why? Adiponectin is a hormone secreted by fat cells. It’s known to have anti-inflammatory effects. This, in turn, leads to higher adiponectin levels being released to combat inflammation.

Dr. Gundry recommends following a lectin-free diet if you struggle with obesity or lectin sensitivity. A lectin free diet can help reduce inflammation and may even lead to weight loss.

Gut Lining, Cortisol, Leptin, and Stress

Cortisol is a stress hormone that can cause inflammation and lead to weight gain. Leptin is a hormone that helps to regulate appetite and energy expenditure. When levels of cortisol or leptin are elevated, it can lead to weight gain.

The gut lining is a barrier that separates the inside of the gut from the rest of the body. When this barrier is damaged, it can allow lectins and other toxins to enter the bloodstream, leading to inflammation. In addition, stress can damage the gut lining, which is why managing stress levels is essential to maintaining good gut health.

Permeability, WBC

Cytokines Permeability measures how easily substances can pass through the gut lining. When the gut lining is damaged, it can become more permeable and allow toxins and bacteria to enter the bloodstream which can lead to inflammation. WBC (white blood cells) are part of the immune system, and they help our bodies fight infection. When the body is exposed to a foreign invader, like a virus or bacteria, our body will increase WBC to fight off the infection. However, if the body is constantly being exposed to foreign invaders, like lectins, it can lead to chronic inflammation. Symptoms of an unhealthy gut include fatigue, brain fog, joint pain, and skin problems.

TNF, Local Inflammation

TNF (tumor necrosis factor) is a type of protein that can cause inflammation. The immune system produces TNF in response to an infection or injury. Local inflammation is when the immune system responds to a disease or damage in a specific area of the body . For example, if you cut your finger, the area around the cut will become red and swollen. This is because the immune system is working to heal the injury. A leaky gut is when the barrier between the inside of the stomach and the rest of the body is damaged. When this barrier is damaged, it can allow toxins and bacteria to enter the bloodstream, which can lead to inflammation.


CRP (C-reactive protein) is a type of protein that is produced in response to inflammation. CRP is a marker of inflammation and can be used to measure the level of inflammation in the body. The American Heart Association recommends that people with heart disease check their CRP levels, as high CRP levels are associated with an increased risk of heart attack and stroke.


T3 (triiodothyronine) is a type of thyroid hormone. Thyroid hormones play a role in metabolism, and low levels of T3 can lead to fatigue and weight gain. In addition, T3 levels can be affected by many things, including inflammation and oxidative stress.

Oxidative stress

Oxidative stress is when there is an imbalance between the production of free radicals and the body’s ability to detoxify them. Free radicals are reactive molecules that can damage cells. They are produced when the body breaks down food or is exposed to environmental toxins. The body has a natural defense system against free radicals. Still, if the body is constantly exposed to them, it can lead to oxidative stress. This can damage cells and lead to inflammation.

Blue Light

Blue light is found in natural sunlight and artificial light, such as computers and TVs. It has been shown to have some health benefits but can also negatively affect the body. For example, blue light exposure at night can suppress the production of melatonin, which can disrupt the sleep cycle. Blue light exposure can also lead to digital eye strain, where the eyes feel tired and dry after watching a screen for an extended period.

Circadian Rhythm

The circadian rhythm is the body’s internal clock that regulates when we sleep, wake up, and eat. It is controlled by the light-dark cycle, which is vital for maintaining a healthy sleep-wake cycle. Unfortunately, blue light exposure at night can disrupt the circadian rhythm and lead to insomnia.
