Phytohemaglutinin, a lectin in beans, has been associated with food poisoning and causes leaky gut and dysbiosis in animal models.

Well SupportedEliminating vegetables led to significant improvements in autoimmune diseases for some individuals.

Well SupportedLectins from beans and cannellini were found in the brains of rats with leaky gut and alpha-synuclein aggregation.

Well SupportedIncluding carbohydrates, particularly as fruit and honey, is beneficial for most humans long-term and represents the least toxic carbohydrate sources.

Well SupportedTripe and stomach contain gastric juices with BPC-157, a peptide known to aid in bodily healing.

Well SupportedTruncal vagotomy is associated with a significantly lower incidence of Parkinson's disease compared to super-selective vagotomy.

Well SupportedLectins are generally most concentrated in plant seeds, including beans, nuts, and grains.

Not SupportedBlood type diets lack scientific basis for specific food recommendations based on blood group.

Partially SupportedMost humans cannot tolerate lectin-containing foods like dairy, eggs, gluten grains, nuts, beans, and nightshades.

Not SupportedStudies on food lectins and red blood cells in test tubes do not demonstrate a clear physiological basis or correlation in the human body for the blood type diet.

Not SupportedLectins are toxic food for humans and require significant detoxification if consumed.

Partially SupportedSufficient sodium intake is important, and Redmond Real Salt is a preferred source.

Partially SupportedType B blood has an additional galactose molecule on red blood cells compared to Type O, and Type A has an additional N-acetylglucosamine molecule.

Partially SupportedType O individuals react to dairy, eggs, gluten grains, and nightshades similarly to Type A1 and A2.

Partially SupportedType B individuals reacted to dairy, eggs, gluten grains, nightshades, sugars, and seafood, similar to Type A1 and A2.

Partially SupportedEliminating the highest lectin foods will help individuals thrive if they are not currently thriving.

Partially SupportedThere is no scientific evidence that any blood type is better than another regarding lectins.

Partially SupportedRaw elderberry is toxic and requires cooking to reduce toxicity.

Partially SupportedDietary lectins may cause dysbiosis in humans.

Partially SupportedGliadin peptides from wheat exhibit in vitro cytotoxic effects on intestinal cells, causing intracellular oxidative imbalance.

Partially SupportedAn autoimmune carnivore diet should eliminate lectin-containing foods.

Partially SupportedThe autoimmune carnivore diet, consisting of grass-fed beef, organs, bone broth, and salt, may help individuals with autoimmune conditions.

Partially SupportedDairy and eggs may trigger fewer people than nuts, seeds, beans, and nightshades, but should be removed for individuals with autoimmunity not improving on a carnivore diet.

Partially SupportedBlood type diets are effective because they eliminate major lectin-containing foods.

Partially SupportedLectins found in foods like lentils can induce histamine release and inflammatory cytokines from human basophils.

Partially SupportedLectins binding to the gut's brush border can damage the mucous layer, allowing gram-negative bacteria to proliferate and cause inflammation and dysbiosis.

Partially SupportedAn animal-based diet is recommended for individuals with autoimmunity or those seeking to optimize performance.

Not SupportedA vegan diet may negatively impact body composition and abdominal definition.

Partially SupportedThere are over 33 recognized blood group systems, making ABO-based food recommendations oversimplified.

Partially SupportedBlood types likely evolved in response to infectious agents, conferring varying susceptibility to infections.

Partially SupportedBlood type O likely emerged about 2.5 million years ago, and blood type AB is a very recent addition, possibly only existing for 1,000-2,000 years.

Partially SupportedHuman primate ancestors exclusively had blood type A.

Partially SupportedA systematic review found no studies validating the health benefits of blood type diets.

Partially SupportedLectins are a real phenomenon with substantial corroborating data.

Partially SupportedAn animal-based diet with low-lectin foods may benefit everyone.

Partially SupportedIndividuals with sensitivities or autoimmune conditions should consider eliminating dairy and eggs, potentially adopting an autoimmune carnivore diet with one carbohydrate source.

Partially SupportedEating nose-to-tail, even in an autoimmune fashion, is recommended for nutritional completeness.

Partially SupportedIndividuals across various blood types reacted to high-lectin foods, suggesting exclusion from diets for autoimmunity.

Partially SupportedMicrobiota profiles may differ between blood types, potentially due to secretor status affecting gut flora.

Partially SupportedLectins play a role in human health and should be avoided as much as possible.

Partially SupportedA decrease in schizophrenia incidence was observed in Sweden during a bread shortage in the 1940s, suggesting a correlation between bread consumption and mental illness.

Not SupportedLectins are not beneficial for humans, regardless of blood type, and the highest lectin-containing foods should be eliminated.

Partially SupportedDietary exposure to plant lectins is widespread.

Partially SupportedType A2B individuals reacted to gluten grains.

Partially SupportedSub-threshold doses of environmental toxins combined with leaky gut and lectins can induce ascending parkinsonism in rats.

Partially SupportedBalancing stearic acid and linoleic acid is important.

Partially SupportedThe autoimmune carnivore diet involves eliminating lectin-containing foods and consuming grass-fed meat and organs, or desiccated organ supplements, bone broth, salt, and potentially honey or fruit.

Partially SupportedNutrients in digestive organs like liver, pancreas, and spleen can help fortify the gut lining.

Partially SupportedType AB blood has both Type A and Type B glycoproteins on the surface of red blood cells.

Partially SupportedBlood types are determined by sugar molecules on red blood cells, mediated by the glycosyltransferase gene on chromosome 9.

Partially SupportedPlants contain lectins, which are carbohydrate-binding proteins, supporting the kernel of truth in the blood type diet concept.

Partially SupportedA 1997 study showed reductions in LDL cholesterol on a low-fat diet, but did not support the blood type diet hypothesis.

Partially SupportedVagotomy prevented Parkinsonian symptoms and constrained alpha-synuclein to myenteric neurons in rats exposed to toxins and leaky gut conditions.

Partially SupportedThe vagal nerve may be critically involved in Parkinson's disease pathogenesis.

Partially SupportedDietary lectin intake can cause diarrhea, impaired nutrient absorption, growth rate inhibition, and potentially death in animal species.

Partially SupportedDietary lectins act as metabolic signals for the gut, modulating immune and hormone functions, which can be detrimental.

Partially SupportedTo follow a low-lectin diet, one should consider eliminating eggs and dairy, and reintroducing them later to check for triggers.

Partially SupportedDifferent blood types can affect the microbiome but do not necessarily dictate specific food choices.

Partially SupportedThe presence of specific antigens on red blood cells dictates the antibodies a person's body produces, influencing immune responses and blood transfusion compatibility.

Not SupportedA 2013 study found no evidence to validate the health benefits of blood type diets.

Not SupportedA diet of only beef and salt can lead to nutrient deficiencies.

Partially SupportedIntact peanut lectin has been identified in peripheral venous blood in humans and is likely detrimental.

Partially SupportedEggs and dairy should be eliminated if an individual is not thriving on an autoimmune carnivore diet.

Partially SupportedExcluding foods high in lectins, such as nuts, grains, seeds, legumes, nightshades, dairy, and eggs, is recommended for those sensitive or seeking an autoimmune carnivore diet.

Partially SupportedThe FUT2 gene determines secretor status, influencing blood group antigen secretion and potentially providing an immunological advantage against infections.

Partially SupportedBlood type A individuals have anti-B antibodies, blood type B individuals have anti-A antibodies, blood type AB individuals have neither, and blood type O individuals have antibodies to both A and B.
