You should drink half of your body weight in ounces. If your body weight is 120 pounds (54 kg), you should drink 60 ounces (1.7 liters) or seven to eight cups (237 ml) daily. Fruits and vegetables can provide about 20 percent of total water intake, while the remaining 80 percent comes from water and other beverages.
According to D'Adamo, people with blood type O should avoid caffeine because it increases their adrenaline levels. However, there are lots of caffeine alternatives out there, ranging from chicory coffee and turmeric latte to barley drink and maca, all of which come with their own set of health benefits.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
Stowell, MD, an associate professor of pathology at Harvard Medical School in Boston. “But these findings do not demonstrate that blood group O individuals are protected from the virus.” Depending on the variant of the virus, the risk of infection may be 25 to 50 percent higher in type A cells versus type O cells.
Peptic ulcer also has a connection with the ABO blood group, and it was the first to be identified. Blood type O individuals showed that they had higher susceptibility to peptic ulcers [1, 9]. Gastritis and ulceration of the stomach/duodenum were later correlated with infection with the bacterium Helicobacter pylori.
People going on the blood type O diet should also keep away from certain types of meat and seafood, and most dairy products. This is because they include hard to digest animal protein. Such meat includes pork, ham, bacon, goose, octopus, caviar, smoked salmon, milk, and milk-based goods such as yogurt and ice-cream.
Excessive sugar consumption (especially sucrose and fructose) can dramatically increase triglycerides in the blood (a real problem for blood type O).
Exercise for Blood Type O - Intense Excercise
A consistent, rigorous exercise program releases the buildup of stress hormones in their systems. The most successful form of exercise for Blood Type Os is cardio based, such as running, cycling and martial arts. If you can't do high intensity workouts, that's OK.
Breads, muffins, and even wheat-free breads are not good for type O's, since most contain some wheat. Essene bread, made from sprouted wheat prepared at a low temperature, can be absorbed and digested by type O's because the gluten lectins (found in the seed coats) are destroyed by the sprouting process.
Small amounts of dairy is OK. Avoid most cheeses, milk, and ice cream. Individuals of African descent should avoid because of lactose intolerance. Other type O's may eat an occasional egg and small amounts of dairy, but it is generally a poor protein source for type O's.
Blood Group: O
People with O blood type should follow a high protein diet, full of lean meats, fish, eggs, kale, lettuce, broccoli, onions, pumpkins, turnip, red peppers, okra, garlic, ginger, cherries, figs, plums, prunes, raspberries, cranberries and gooseberries.
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.
Dairy & Eggs
Other type O's may eat an occasional egg and small amounts of dairy, but it is generally a poor protein source for type O's. Instead, use non-dairy milk alternatives, including soy, rice, and almond milks. Soya milk and cheese are excellent high-protein alternatives for type O's.
Type O should include lean beef meat, lamb, turkey and chicken in their diet. Especially, more intakes of seafood, kelp and iodized salt will increase hormone production. They should also eat egg, nuts and seeds in moderation.
People with blood type O may have a significantly lower risk for developing type 2 diabetes than those with blood types A, B or AB, according to data published in Diabetologia.
Nuts are a great source of protein and good fats, both of which favor O blood groups.
“If you have O blood type, you may have slightly lower risk of some diseases like thrombosis, but it doesn't completely protect you from the risk,” she says. Thrombosis occurs when clots block blood vessels. Knowing your blood type may give you added insight into your heart health, Salazar says.
Seafood is an excellent, low fat source of protein. Cold water fish, which are rich sources of Omega 3 fats, such as cod, mackerel, tuna and salmon are beneficial for inflammatory diseases like arthritis, eczema and asthma. Type O's often have under-active thyroid function, and the iodine in seafood is very beneficial.
Because those with type O blood tend to fare better with high-protein diets, corn, oats, and wheat products are to be avoided. Kidney and navy beans, as well as lentils also tend to cause weight gain in type O's. Grains in the type O diet should include barley, buckwheat, quinoa, rye, spelt and rice.
Blood type O can actually have more problems with catecholamines, when they do produce a large amount in response to stress, it can take them a while to eliminate them and their effects. Another critical hormone to consider is cortisol which is also made and released from your adrenal glands.
Blood type and stress
Type A may exhibit more anxious behaviour than other types. The blood types B and AB have been found to respond better to stress. And blood type O was found to have the lowest amounts of cortisol in their bodies.
Types O negative and O positive are in high demand. Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population).
