What You'll Learn
Eat lean meats, fish, and vegetables
The O positive blood type diet is based on the idea that eating certain foods suited to your blood type can improve your health. According to naturopathic physician Peter D'Adamo, who developed the blood type diet in 1996, the O positive diet may have several health benefits. However, it is important to note that there is little scientific evidence to support this claim, and more research is needed to understand the link between blood types and diets.
One of the key recommendations of the O positive blood type diet is to focus on consuming lean meats, fish, and vegetables while limiting wheat, alcohol, and dairy, which may trigger digestive issues. Here are some detailed instructions and benefits of including lean meats, fish, and vegetables in the diet for individuals with type O positive blood and diabetes:
Lean Meats
Lean meats are recommended for people with diabetes as they are lower in unhealthy fats, which can increase cholesterol and the risk of heart disease. When choosing meats, opt for lean options such as certain cuts of beef, pork, and chicken. These meats can provide a good source of protein while helping to limit the intake of saturated fats. It is important to note that the amount of meat consumed should vary based on individual factors such as age, body size, and activity levels.
Fish
Including fish in the diet is recommended by the American Diabetes Association, with a suggestion to consume fish at least twice a week. Fish that are high in omega-3 fatty acids, such as salmon, Albacore tuna, mackerel, herring, rainbow trout, and sardines, are beneficial. Additionally, other types of fish like cod, halibut, haddock, and flounder, as well as shellfish, can be included. Oily fish, in particular, may help reduce the risk of cardiovascular disease. However, it is important to consider the preparation method, as deep-fat frying can decrease the beneficial effects of fish by lowering the content of beneficial fatty acids.
Vegetables
Consuming a variety of vegetables is essential for individuals with diabetes. Vegetables provide excellent sources of fiber, which helps regulate blood sugar spikes. Raw or lightly cooked vegetables have higher fiber content than processed or fried varieties. Vegetables rich in naturally occurring nitrates, such as spinach, can help reduce blood pressure and improve circulatory health. While starchy vegetables like potatoes are high in carbohydrates, they can still be included in moderation as part of a diet plan developed with a healthcare professional. It is recommended to opt for fresh, plain, or minimally processed vegetables and to flavor them with herbs, spices, or low-salt seasonings.

Limit grains, dairy, and legumes
The O positive blood type diet suggests that people with different blood types should eat differently to improve digestion and energy levels. However, it is important to note that there is limited scientific evidence supporting this theory.
The O positive blood type diet recommends a high-protein diet that limits grains, dairy, and legumes. According to this dietary approach, people with O-positive blood should focus on consuming lean meats, fish, vegetables, and fruits.
Grains:
When it comes to grains, the recommendation is to limit wheat and corn. This is because the O positive blood type diet suggests that these grains may trigger digestive issues. Instead of wheat and corn, those following the diet may opt for whole grains such as brown rice or whole-grain bread. Whole grains can be beneficial for managing blood glucose levels as they often have a lower glycemic index and can help keep blood sugar levels stable.
Dairy:
The O positive blood type diet suggests limiting dairy products, as they may also trigger digestive issues. However, dairy products are a source of essential nutrients, including calcium, protein, and vitamins. For those who choose to include dairy in their diet, it is recommended to opt for low-fat or fat-free dairy options without added sugar. Plant-based milk, such as unsweetened soy milk, can be a healthy alternative, although it may be lower in sugar than cow's milk.
Legumes:
The O positive blood type diet suggests limiting legumes, including kidney beans. Legumes are a good source of high-quality carbohydrates and fiber, which may help slow the absorption of glucose. However, the diet recommends limiting them due to the belief that they may cause digestive issues.
It is important to remember that the O positive blood type diet is not based on extensive scientific evidence, and there is limited research on its benefits. Before making significant changes to your diet, it is advisable to consult with a healthcare professional or a registered dietitian nutritionist.

Consume fruits and healthy fats
The O positive blood type diet suggests eating foods that are suited to this blood type. It recommends a high-protein diet with lean meats, fish, vegetables, and fruits, while limiting wheat, corn, legumes, kidney beans, dairy products, caffeine, alcohol, and grains. However, it is important to note that there is limited scientific evidence supporting this theory.
For people with type 2 diabetes, consuming fruits and healthy fats is essential for a healthy meal plan. Fruits are a good source of vitamins and fiber, and they can help satisfy your sweet tooth without adding excess sugar to your diet. When choosing fruits, opt for fresh, frozen, or canned options without added sugars. Berries, citrus fruits, and melons are excellent choices. Be mindful of portion sizes, as fruit contains carbohydrates that can impact blood sugar levels.
Healthy fats are an integral part of a diabetes-friendly diet. Nuts, seeds, and avocados are excellent sources of healthy fats, providing monounsaturated fats and omega-3 fatty acids. These foods help manage hunger and provide essential nutrients like magnesium and fiber. Additionally, healthy fats like olive oil are recommended for cooking and salad dressings.
It is important to note that individuals with type 2 diabetes should also prioritize consuming non-starchy vegetables, whole grains, lean proteins, and low-fat dairy products. These foods provide essential nutrients, keep you feeling full for longer, and help manage blood sugar levels.
While the O positive blood type diet recommends limiting grains and dairy, the specific needs of individuals with type 2 diabetes may vary. Consulting with a healthcare professional or a registered dietitian nutritionist is advisable to determine the best dietary approach for managing diabetes and ensuring overall health.

Take supplements
While there is limited scientific evidence to support the O-positive blood type diet, it is believed to promote healthy eating habits and may lead to intended weight loss. According to Dr. Peter D'Adamo, naturopathic physician and author of the book "Eat Right 4 Your Type," eating a diet specific to your blood type can improve digestion and increase energy levels.
Vitamin D
Vitamin D is essential for maintaining strong bones and a healthy immune system. It can be obtained through exposure to sunlight, but it is also available as a supplement. Vitamin D supplements are typically recommended for individuals who live in regions with limited sunlight or who have conditions that affect their vitamin D absorption.
Omega-3 Fatty Acids
Omega-3 fatty acids are beneficial for cardiovascular health and can be found in foods such as fatty fish (salmon, tuna, sardines), flaxseeds, and walnuts. They help reduce inflammation in the body and lower the risk of heart disease and stroke. Omega-3 supplements are often recommended for individuals who do not consume enough of these foods to meet their omega-3 needs.
Probiotics
Probiotics are live microorganisms that provide health benefits when consumed. They are often referred to as "good" bacteria and are commonly found in fermented foods like yogurt, kefir, sauerkraut, and kimchi. Probiotics support digestive health, boost the immune system, and may even improve mental health. Probiotic supplements are typically recommended for individuals who want to restore the balance of bacteria in their gut, especially after taking antibiotics or experiencing digestive issues.
Digestive Enzymes
Digestive enzymes help break down food into smaller particles that can be easily absorbed by the body. They are produced naturally by the body, but certain health conditions or digestive issues may lead to a deficiency. Taking digestive enzyme supplements can aid in improving digestion, reducing bloating and gas, and enhancing the absorption of nutrients from food.
It is always recommended to consult with a healthcare professional or a registered dietitian nutritionist before starting any new diet or supplement regimen, especially if you have specific health concerns such as diabetes. They can provide personalized advice based on your individual needs and health status.

Exercise regularly
Exercise is an important component of a healthy lifestyle, especially when managing a condition like diabetes. Regular physical activity can help improve blood sugar control, enhance insulin sensitivity, promote weight management, and reduce the risk of diabetes-related complications. For individuals with type O positive blood, combining a diet plan with vigorous aerobic exercise is recommended.
It is suggested that individuals with type O positive blood focus on incorporating vigorous aerobic exercises into their fitness routine. This can include activities such as running, swimming, cycling, or high-intensity interval training (HIIT). These exercises elevate the heart rate and promote increased blood flow throughout the body, improving cardiovascular health and endurance.
In addition to aerobic exercises, strength training can also be beneficial for individuals with type O positive blood. Incorporating exercises such as weightlifting, bodyweight exercises, or resistance band workouts can help build and tone muscle, improve bone density, and enhance overall strength.
Yoga and Pilates are also great additions to an exercise routine. These practices focus on flexibility, balance, and core strength, improving stability and posture. Additionally, the mindfulness aspect of these exercises can help reduce stress and promote a sense of calm, which is beneficial for overall well-being.
For individuals with type O positive blood, it is recommended to consult with a healthcare professional or fitness trainer to design an exercise program that suits their specific needs and fitness level. It is important to start slowly and gradually increase the intensity and duration of workouts to avoid injury and promote long-term adherence.
