Y lo importante es que cada grupo sanguíneo reacciona de manera diferente ante ellas. Es decir, hay lectinas alimentarias –hablamos siempre generalizando- que son rechazadas por las personas de un tipo de sangre mientras no ocurre así con otros para los que incluso son beneficiosas. www.dsalud.com/reportaje/condiciona-el-grupo-sanguineo-nuestra-alimentacion/
AFINIDAD DE FRACCIONES CONCENTRADAS DE LECTINAS DE FRIJOL TÉPARI (Phaseolus acutifolius) POR ERITROCITOS HUMANOS García Santoyo V1, Mendiola Olaya E2, Blanco Labra A2, García Gasca T3. 1Facultad de Química. 3Facultad de Ciencias Naturales.

RESUMEN Las lectinas son proteínas capaces de unirse a moléculas de azúcar. Los eritrocitos presentan en su membrana glicoproteínas que pueden ser reconocidas de manera específica o inespecífica por
lectinas causando aglutinación. Dicha aglutinación puede ser inhibida por carbohidratos que presenten mayor afinidad por la lectina. El objetivo del trabajo fue determinar el grado de afinidad de una fracción concentrada de lectina (FCL) de frijol térapi (Phaseolus acutifolius) y sus dos subfracciones separadas por cromatografía de exclusión de peso molecular (pico A, PA y pico B, PB) así como la afinidad por diferentes carbohidratos de la fracción más activa. Se obtuvo sangre de donadores voluntarios, la cual se tipificó de acuerdo a los antisueros contra sangre tipo A, B y O, todas con Rh positivo. Los eritrocitos fueron fijados con glutaraldehído y la actividad aglutinante se determinó mediante el método de diluciones dobles seriadas. El PA fue capaz de diferenciar entre eritrocitos de distinto tipo sanguíneo además de presentar mayor afinidad por eritrocitos de tipo A+. Estas propiedades no las presentaron la FCL y PB. Por otro lado, se observó que PA presentó mayor afinidad por carbohidratos como xilosa, maltosa, rafinosa y glucosa. Los resultados obtenidos muestran que la FCL y las subfracciones PA y PB presentan lectinas con diferentes grados de afinidad y los eritrocitos humanos A+ fueron son los más afines. CONCLUSIONES La fracción PA fue más afín a eritrocitos de tipo A+, además de que identificó entre eritrocitos de tipo A+, B+ y O+. La FCL y PB no fueron capaces del reconocimiento diferencial. El PA presentó mayor afinidad por xilosa, maltosa, rafinosa y glucosa. Los resultados sugieren que PA y PB contienen diferentes lectinas o formas con diferente actividad. https://www.uaq.mx/investigacion/difusion/veranos/memorias-2009/11VCRC_46/10_Garcia_SantoyoV.pdf
Diet not working? Maybe its not your type
August 22, 2019 By Robert H. Shmerling, MD, Senior Faculty Editor, Harvard Health Publishing https://www.health.harvard.edu/blog/diet-not-working-maybe-its-not-your-type-2017051211678
Have you heard of the blood type diet? I thought it had been debunked long ago but patients keep asking about it, so I figured I should learn more.
What’s the Blood Type Diet?
In 1996 Peter D’Adamo, a naturopathic physician, published a book in which he described how people could be healthier, live longer, and achieve their ideal weight by eating according to their blood type. One’s choice of condiments, spices, and even exercise should depend on one’s blood type. Soon, the book was a best seller and people everywhere were finding out their blood type, revising their grocery lists, and changing how they ate, exercised, and thought about their health.
Here are some of the recommendations according to the “Eat Right for Your Type” diet:
- Those with type O blood should choose high-protein foods and eat lots of meat, vegetables, fish, and fruit but limit grains, beans, and legumes. To lose weight, seafood, kelp, red meat, broccoli, spinach, and olive oil are best; wheat, corn, and dairy are to be avoided.
- Those with type A blood should choose fruit, vegetables, tofu, seafood, turkey, and whole grains but avoid meat. For weight loss, seafood, vegetables, pineapple, olive oil, and soy are best; dairy, wheat, corn, and kidney beans should be avoided.
- Those with type B blood should pick a diverse diet including meat, fruit, dairy, seafood, and grains. To lose weight, type B individuals should choose green vegetables, eggs, liver, and licorice tea but avoid chicken, corn, peanuts, and wheat.
- Those with type AB blood should eat dairy, tofu, lamb, fish, grains, fruit, and vegetables. For weight loss, tofu, seafood, green vegetables, and kelp are best but chicken, corn, buckwheat, and kidney beans should be avoided.

How Your Blood Type Can Affect Your Health
Medically Reviewed by Minesh Khatri, MD on March 24, 2020 https://www.webmd.com/a-to-z-guides/ss/slideshow-how-your-blood-type-affects-your-health
Heart Disease
1 / 13
There’s good news for O blood types. Research shows your risk of coronary heart disease tends to be lower. Experts aren’t sure why. Some think it might be because other types are more likely to have higher cholesterol and higher amounts of a protein that’s linked to clotting. Swipe to advance
Stomach Cancer
2 / 13
A, AB, and B blood types are more at risk than type Os. Specifically, people with type A blood are more likely to get stomach cancer. Researchers think this might be because H. pylori infection is more common in people with type A blood. That’s a bacteria that’s usually found in the stomach. It can cause inflammation and ulcers. Swipe to advance
Memory
3 / 13
A small study showed that people with memory problems had type AB blood more than any other. Swipe to advance
Pancreatic Cancer
4 / 13
Your risk is higher if you’re type A, AB, or B. Molecules in type A and B red blood cells help certain bacteria called H. pylori grow in your gut. It can make you more likely to get pancreatic cancer. Swipe to advance
Stress
5 / 13
Stress boosts your body’s level of cortisol, the stress hormone. People with type A blood tend to have more cortisol, anyway. So you may have a harder time dealing with stressful situations. Swipe to advance
Malaria
6 / 13
Type O blood may help ward off this disease. You can get malaria when an infected mosquito bites you. The parasite that causes it has a harder time attaching itself to type O blood cells. Swipe to advance
Ulcers
7 / 13
Peptic ulcers — painful open sores that crop up in the lining of your stomach or upper intestine — seem to happen more often with blood type O. Swipe to advance
Blood Clots
8 / 13
Venous thromboembolism (VTE) is when your blood clots in a deep vein, like the ones in your legs. These clots sometimes move to your lungs. Research shows that people with type A, B, or AB blood are at a higher risk of VTE. Swipe to advance
Life Span
9 / 13
Chances are higher you’ll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this. Swipe to advance
Fertility
10 / 13
Your blood type can’t predict whether you’ll get pregnant, but it may play a role. In one study, women with low numbers of healthy eggs were more likely to have type O blood than any other type. More research is needed to figure out why. Swipe to advance
Diabetes
11 / 13
Type 2 diabetes seems to happen more often in people with blood types A and B. Experts aren’t sure why. More research is needed. Swipe to advance
Stroke
12 / 13
Your risk for a stroke goes up if you have blood type AB. Doctors think that’s because it’s more likely to clot than other types. Swipe to advance
Are Certain Blood Types More Prone to Autoimmune Diseases?
Diabetes
Type 2 diabetes is when your body becomes resistant to the hormone insulin or doesn’t produce enough insulin. Some researchersTrusted Source hypothesize that type 2 may also be an autoimmune disorder, but more research is needed to understand how it develops.
The data is conflicting in this area, as you can see from some recent research results:
- A 2020 study found that in a group of 424 people, O blood type was associated with a decreased risk of type 2 diabetes, and blood type B was associated with an increased risk.
- Another 2020 studyTrusted Source looked at 750 participants and found that risk of developing type 2 diabetes was higher in blood group A than those in any other blood group.
- In a 2017 study from Pakistan, researchers found similar results. They discovered that in a group of 2,258 university students, people with a B blood type were more likely to develop diabetes than those with other blood types.
- A large 2015 studyTrusted Source of 82,104 women showed that people with type O blood had a lower risk for type 2 diabetes, while both A and B blood type groups were shown to be at a higher risk with no association in Rh factor.
Overall, the data regarding blood type and its association with diabetes is still very conflicting and requires continued research.
Rheumatic disease
Rheumatic disease is a group of more than 200 conditions that cause pain in your joints, connective tissue, tendons, and cartilage. Many of these conditions are autoimmune disorders.
A 2017 studyTrusted Source from Turkey examined the connection between blood type and the prevalence of autoimmune rheumatic disease. The researchers found that some conditions were more common in people with certain blood types.
Diseases that were most common in people with type A blood were:
- spondyloarthropathy
- vasculitis
- undifferentiated connective tissue disease
- Behçet’s disease
- rheumatoid arthritis
Diseases more common in people with type O were:
- familial Mediterranean fever
- systemic lupus erythematosus
- systemic sclerosis
- Sjögren’s syndrome
All diseases were less common in people with blood type AB.
Most people with rheumatic disease — 92.2 percent — had an Rh+ blood type.
Lupus
Lupus is an autoimmune disease that causes inflammation and pain throughout the body. The symptoms are usually concentrated in one area such as your joints, skin, or organs.
The most common cause of lupus is called systemic lupus erythematosus.
A 2019 study from Iran found that in a group of 146 people with systemic lupus erythematosus, those with blood type A or B had more severe symptoms than people with other blood types.
In a Brazilian study from 2009, researchers found no difference in blood type ratios between people with discoid lupus erythematosus and the local population. However, they did find that blood type A was associated with an increased risk of experiencing symptoms outside the head and neck.
Inflammatory bowel disease
There are two main types of inflammatory bowel disease (IBD) — ulcerative colitis and Crohn’s disease.
Here is a brief overview of some of the recent data on IBD and blood type:
- A 2016 Chinese studyTrusted Source found no association between blood type and the prevalence of Crohn’s disease in a group of 293 people. The researchers found that people with blood type AB responded better to the medication infliximab, while those with type A seemed to have an increased risk for losing response to it.
- A 2020 study found no association between the prevalence of ulcerative colitis and blood type in a group of 129 patients from Taiwan.
- A 2020 studyTrusted Source from Korea showed a possible protective effect of having blood type O in those with Crohn’s disease.
- A 2014 study involving participants from Italy and Belgium demonstrated similar results of the 2020 Korean study above, showing that those with blood type O had a lower chance for developing Crohn’s disease or having a severe form of the disease.
Multiple sclerosis
MS is an autoimmune condition that occurs when your immune system attacks a protective layer around your nerves called myelin.
A 2019 studyTrusted Source found that in a group of 265 people, those with blood type A+ or B+ had an elevated risk for developing MS. The study also found that people without the antigens A, B, or Rh+ had a decreased risk.
Hashimoto’s disease
Hashimoto’s disease is the most common cause of underactive thyroid in the United States. It’s caused by your immune system attacking and damaging thyroid cells.
A 2019 studyTrusted Source found evidence that there may be an association between having blood type O and Hashimoto’s disease. A group of 958 people with thyroid disease were included in the study, and 550 of these people had Hashimoto’s disease.
The ratio of people with blood type O was found to be higher among those with Hashimoto’s than in people with other thyroid diseases. They also found that autoimmune diseases were reported significantly less often in people with blood type AB. https://www.healthline.com/health/blood-type-and-autoimmune-diseases
What Does Your Blood Type Mean for Your Health?
What Recent Studies Suggest
There are eight main blood types: A+, A-, B+, B-, O+, O-, AB+ or AB-. Knowing your blood type can be crucial in a medical emergency, but it can also offer some interesting insight into your health. See how your blood type might play a role in your well-being, based on results of some recent studies.
Heart Disease
Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.
Cancer
Studies have found that people with blood type A or AB are at higher risk for stomach cancer. Additionally, if you have A, B or AB blood types, you may have an increased risk for pancreatic cancer. If you fall in this grouping, stock up on cancer-fighting foods, which can help reduce the risk for developing cancer.
Stress
If you have type A blood, you may have more trouble handling stress. Those with type A tend to have heightened levels of cortisol, the stress hormone, in the body. Here are small steps to reduce anxiety and stress and how to stay healthy.
Knowing your blood type is one more way to better understand and manage your health. While your blood type is a genetic gift that cannot be altered, making healthy choices can help you reduce the risks to your health.

Biotype Diets System®: Blood types and food allergies
Laura PowerPages 125-135 | Published online: 13 Jul 2009 Download citation https://doi.org/10.1080/13590840701352807 Abstract
Purpose: The goal of this research was to determine patterns in adverse food reactions among human biotypes, if any.
Design: Blood types A1, A2, B, AB, O and Rh‐negative were correlated to four kinds of food allergies and hypersensitivities.
Materials and Methods: Three studies were conducted from 1985 to 2004. Blood types were correlated to food scores from: (1) mRAST‐IgE food allergy tests, (2) mRAST‐IgG food hypersensitivity tests, and (3) T‐cell food hypersensitivity tests (ELISA/ACT® LRA). An allergy history was recorded. Data were evaluated by statistical analyses, including: ANOVA, MANOVA, Mann–Whitney U, Kruskal–Wallis, and Chi Square. Clinical categories were established by means and ranges. (4) Blood‐type specific lectins were included from the scientific literature.
Results: Results were reported by blood types and food groups as raw scores and classes, and included the following: blood type A1 reacted most strongly to nuts and beans, eggs, dairy, and nightshades; while type A2 reacted to the same but more strongly to dairy, eggs and gluten grains. Type B reacted most to eggs, nuts and beans, dairy, gluten grains, nightshades, and sugars. Type O reacted most to dairy, eggs, gluten grains, and nightshades. Type AB reacted most to nuts and beans, seafood, eggs, and dairy; while A2B also reacted to gluten grains. Type Rh‐negative was most reactive to eggs, dairy, nuts and beans, and gluten grains. The highest IgE scores were among types B and Rh‐negative. The highest IgG scores were among types O, A2 and Rh‐negative. The most lectins reacted with type AB.
Conclusions: The research showed patterns in food group allergies and hypersensitivities based on ABO, A1/A2 and Rh blood types. Biotype Diets is the first diet‐typing system supported by original scientific research, and has greater accuracy and specificity than other systems.

Blood Type Diet and Allergies Apr 4th, 2017 by Dr. Peter J. D’Adamo https://www.4yourtype.com/blog/blood-type-diet-and-allergies/
It’s true— certain foods can in fact make your seasonal allergies worse. Alcohol, peanuts, sugar, processed foods, wheat, chocolate, and even your morning cup of coffee are known culprits that act as hay fever catalysts.
How Changing Your Diet May Improve Seasonal Allergies
Prevalence of ABO Blood Groups and their Association with Dust, Pollen and Skin Allergy in Young Adults ABSTRACT Objectives: To find prevalence of ABO blood groups and to investigate their association with dust, pollen and skin allergy. Materials and Methods: This cross sectional study was done at Islamabad Medical & Dental College Bhara Khou Islamabad Pakistan from April 2011 to May 2012. n= 123, both male and female First year M.B; B.S students 18-21 years of age were enrolled for the study during Hematology module. ABO blood group of study population was done by antisera method. A detailed history of study population regarding dust, pollen and skin allergies was recorded on a preformed Performa. Result: In our study population B blood group came out to be the most common (34%). History of allergy was reported by 65 % of our study population. Dust allergy and pollen allergies were found high among individuals with B blood group being 43% and 43.75% respectively. Skin allergy was reported high among A blood group individuals (40%). Blood group AB was found to be at lowest risk level for allergies. The study showed association between blood groups and allergies as < 0.0007 statistically significant p-value. Conclusion: In the study population blood group B being the most common is at high risk level for developing allergies. Blood groups A and O were found to have nearly same level of allergies while Blood group AB being the most protected one. This statistically significant association of various blood groups with allergy development could help in identifying people at risk as an aid to preventive measures. Key words: Blood groups, risk, allergy, dust, pollen, association.
