When I first started researching the best foods for blood type O positive, I was overwhelmed by the sheer amount of information available.

If you are looking for a Blood Type O Positive Diet Food List PDF, this guide will provide you with the necessary details to make informed dietary choices and improve your health.
Understanding the Blood Type O Positive Diet

Blood type O positive is considered one of the oldest blood types, linked to our hunter-gatherer ancestors. This historical background suggests that individuals with this blood type thrive on high-protein diets, rich in lean meats, fish, and vegetables. Since our ancestors relied on hunting and gathering, our digestive systems are believed to be optimized for digesting animal proteins efficiently.
When I started following this diet, I noticed a significant change in my energy levels. My digestion improved, and I felt less bloated compared to when I consumed processed foods and dairy. This experience reinforced my belief that this diet could be beneficial for others with the same blood type.
Blood Type O Positive Diet Food List
Best Protein Sources for Blood Type O Positive
The foundation of the Blood Type O Positive Diet is protein. Here are the best protein sources:
- Lean Meats: Beef, lamb, turkey, venison
- Fish & Seafood: Salmon, cod, mackerel, sardines, herring
- Eggs: Though some experts suggest limiting them, I found that they worked well for me in moderation.
During my transition to this diet, I included more fish and lean meats, and I noticed an improvement in my metabolism. My workouts became more effective, and I felt fuller for longer.
Vegetables for Blood Type O Positive
Vegetables play a critical role in this diet. The best options include:
- Leafy Greens: Kale, spinach, romaine lettuce, Swiss chard
- Cruciferous Vegetables: Broccoli, cauliflower, Brussels sprouts
- Other Beneficial Vegetables: Onions, garlic, red peppers, carrots
I used to rely heavily on starchy vegetables like potatoes, but I realized that my digestion improved significantly when I replaced them with leafy greens. The difference in my energy levels was remarkable.
Fruits to Eat and Avoid
Fruits are also essential, but not all fruits are beneficial for blood type O positive individuals.
Best Fruits:
- Berries (blueberries, strawberries, blackberries)
- Plums
- Bananas
Fruits to Avoid:
- Oranges
- Melons
- Strawberries (some variations suggest avoiding them)
At first, I found it challenging to limit citrus fruits because I used to love having orange juice in the morning. However, once I reduced my intake, I noticed a decrease in acid reflux and bloating.
Foods to Avoid on a Blood Type O Positive Diet
Grains and Dairy
One of the biggest adjustments I had to make was reducing my consumption of grains and dairy. Blood type O individuals often struggle with digesting these foods.
Avoid:
- Wheat, barley, corn
- Dairy products like milk, cheese, and yogurt
I was skeptical at first, but cutting out dairy made a world of difference. I felt less bloated and more energetic throughout the day.
Processed Foods and Legumes
Processed foods are problematic for almost everyone, but for blood type O individuals, they can cause inflammation and digestive issues.
Avoid:
- Processed meats (sausages, deli meats)
- Beans and legumes (kidney beans, lentils, peanuts)
- Artificial sweeteners and refined sugars
I used to snack on peanut butter regularly, but after eliminating it from my diet, I experienced fewer digestive problems and more stable energy levels.
Healthy Fats and Oils
Healthy fats are crucial for this diet. The best options include:
- Olive oil
- Flaxseed oil
- Walnuts
- Almonds (in moderation)
Switching to olive oil for cooking and salads was one of the best dietary changes I made. Not only did my meals taste better, but I also noticed improvements in my skin and digestion.
Exercise and Lifestyle for Blood Type O Positive Individuals
Diet alone isn’t enough; exercise plays a crucial role in maintaining good health for blood type O positive individuals. Our ancestors were active, which means our bodies respond well to high-intensity workouts.
Recommended Exercises:
- Cardio workouts (running, cycling, swimming)
- Strength training
- HIIT workouts
I started incorporating more cardio into my routine, and within weeks, I felt more energetic and mentally sharp.
