Can Blood Type Diet help for Cancer?

Why Blood Type Diet helps treat and prevent Cancer

The blood type diet is suggested to treat and prevent cancer because it helps boost the immune system and fight malignant cells by providing each blood type with the proper foods to do so.

In addition, people with specific blood types need to avoid certain foods with harmful lectins that may cause an unnecessary immune response, weakening the body’s immune system.

The blood type diet advises people of each blood type to eat foods with beneficial lectins that help fight cancer cells. These lectins clump around cancer cells, allowing the immune system to identify and destroy them.

The lectins help blood types that cannot identify T or Tn antigens target and kill cancerous cells. Some lectins in specific foods also prevent the growth and spread of cancer cells by deactivating the EGF receptors in cancer cells.

In 2007, a study examining the use of lectins in cancer treatment titled “Lectins as Bioactive Plant Proteins: A Potential in Cancer Treatment” found that some lectins have anti-cancer properties and can be used to kill cancer cells. This study partly supports Peter D’Adamo’s hypothesis about beneficial lectins targeting and destroying cancer cells.

However, it does not examine if specific blood types react differently to different lectins in foods. Thus, it does not fully validate the main hypothesis of the blood type diet.

The blood type diet also addresses the issue of increased blood clotting factors that help cancer cells circulate throughout the body in type A and AB individuals.

It prescribes suitable foods that do not contain harmful lectins to each blood type. The foods prevent the blood from clotting and slow the spread of cancer cells in the body.

How the Blood Type Diet works for Cancer

The blood type diet works by prescribing specific foods for each blood type to boost the body’s immune system. Some foods contain beneficial lectins that can fight cancer cells. These lectins are suggested to clump around and bind to the cancer cells, allowing the immune system to target them and kill them.

For instance, blood types A and AB should consume beneficial lectins found in peanuts and ancient grains, such as amaranth, because they help the immune system fight cancer cells. All blood types should consume more fruits and vegetables to fight cancer because they contain fiber and protect the digestive system.

Plus, individuals should avoid consuming foods with harmful lectins for each blood type to prevent an unnecessary immune response. If people avoid these foods, their bodies will have a more robust immune system and more energy to track and fight cancer cells.

Furthermore, people of specific blood types should avoid foods that stimulate the production of Epidermal Growth Factor (EGF) because it promotes cancer cell growth. For instance, blood types A and AB should avoid consuming wheat products and fatty foods because they stimulate the production of EGF and the growth of cancer cells.

In addition, blood type A and AB individuals have more clotting factors in their blood than blood type O and B. Blood clotting factors like Factor VIII and fibrinogen help cancer cells spread throughout the body more easily. Both fibrinogen and Factor VIII are proteins that allow cancer cells to attach to platelets and blood vessels and circulate throughout the body.

Accordingly, this food regimen restricts different kinds of foods with harmful lectins that cause blood to clot for each blood type. The absence of clotting factors decreases platelet levels in the blood vessels. As a result, cancer cells will no longer bind to the platelets nor stick to blood vessel walls that serve as an entry point to other tissues in the body.

The Blood Type Diet foods for Cancer

The blood type is not based on the amounts of macronutrients or calories your body consumes. Instead, it focuses on restricting food groups for each blood type to help maintain proper body functions and prevent and treat medical conditions.

The food types for each blood type are listed below:

-  Blood Type O: can eat lean meat, poultry, fish, and vegetables, and fewer grains, beans, and dairy.

-  Blood Type A: can eat more fruits and vegetables, beans and legumes, and whole grains with little to no meat (vegetarian diet).

-  Blood Type B: can eat green leafy vegetables, eggs, most meats (except chicken and pork), and low-fat dairy. They should avoid wheat, corn, lentils, tomatoes, peanuts, and sesame seeds.

-  Blood Type AB: can eat seafood, tofu, dairy, beans, and grains. They should avoid kidney beans, corn, beef, and chicken.

Blood Type Diet foods by blood type

The blood type diet suggests that each blood type can prevent cancer if they eat specific foods to boost the immune system and fight unregulated cancer cells.

Below is a list of foods that help prevent cancer for each blood type:

- Richly-oiled cold water fish (prevents blood clots)

- Snails (prevents cancer cells from spreading into lymph nodes)

- Flax oil (contains linoleic acid and fights cancer cells)

- Cultured dairy foods like yogurt, kefir (inhibit the growth of cancer cells)

- Fruits (protect the digestive system)

- Vegetables (protect the digestive system)

Blood Type Diet for Cancer: Recommendations to Follow

- Eat fresh and organic fruits and vegetables: fresh or organic fruits and vegetables have more nutrients. If people eat fruits and vegetables have been sprayed with pesticides, the chemicals in the pesticides could cause the body to believe it is under attack and overwork the body’s immune system, eventually weakening it.

- Take certain supplements depending on your blood type: the diet restricts the consumption of meat and dairy for specific blood types. This may result in malnutrition, so some blood types must take nutritional supplements to ensure that they get the vitamins and minerals their body needs. 

o Blood type O individuals need to take Vitamin C, B12, iron, and folic acid supplements.

o Blood type A individuals need to take Vitamin B, K, calcium, and licorice supplements.

o Blood type B individuals need to take magnesium, ginkgo, licorice, and lecithin supplements. 

o Blood type AB individuals need to take Vitamin C, B12, and iron supplements.

- Exercise: the diet recommends different kinds of exercise based on your blood type.

The different types of exercise for each blood type are listed below:

o Blood type O: People who are type O should engage in intense exercising activities like jogging or biking.

o Blood type A: People who are type A should focus on low-level activity and stress-relieving exercises like yoga or tai chi.

o Blood type B:  People who are type B should focus on moderate-level exercise and can include yoga or other mindfulness practices.

o Blood type AB: People with type AB blood can combine exercises from blood types A and B.

Blood Type Diet for Cancer: what you should avoid

All of the blood types should avoid:

- Processed meats: this is because processed meats contain high levels of saturated fat. They also contain sodium nitrite. Sodium nitrite can react with chemicals in the stomach and cause cancer.

- Foods that are high in sugar: high sugar foods can cause oxidative DNA damage and mutations that cause cancer.  Sugary foods increase the risks of pancreatic, gastric, colorectal, and prostate cancer.

- Simple carbohydrates: simple carbohydrates can cause weight gain and can be linked to certain types of cancer. Simple carbohydrates also contain processed sugar, which increases the risk of cancer.

- Foods that are high in fat: fatty foods stimulate the production of EGF and promote cancer cell growth.

The Blood Type Diet for Cancer: precautions

The diet can be restrictive for some blood types, like type A and type O, so the person must be careful to receive the vitamins and minerals that the body needs from other food sources.

Blood types that limit dairy must add new sources of vitamin D and calcium to their diet because both calcium and vitamin D protect the body against cancer.

Always consult with a health expert before starting any diet, especially if you have a chronic health condition like diabetes, heart disease, or if you are taking any medication.

Always consult with a healthcare professional before starting any new diet or treatment.
