First post in a series for Eating Right For Your Blood Type. Each post will cover a different, in-depth look at what you should be eating for your individual blood type.
Recently, I have been slowly transitioning for a diet that is more catered to my health conscience lifestyle. While the major 'designer' diets out there work great for people who are looking to loose a drastic amount of weight, there is a major sub-population of people who'd like a diet for their everyday life. Everyone can gain nutritional and physical advantages by simply making healthy choices and using alternatives for 'junk' nutrition. The Eat Right For Your Blood Type Diet, caters to your specific blood type and provides the best solution for your genetic predispositions.
I had never really thought about how really so much of our body is predetermined by our genetics. We all know there are 'big boned' vs 'small boned' people, but did you know that depending on what type of blood type you are, you might be predisposed for Crone's or other type of diseases? That's why a diet built around our blood type can be beneficial to all.
While the Eat Right 4 Your Blood Type book by Dr. Peter J. Adamo is your best bet on gaining all the information you need for your specific type, like what foods to avoid and why, here's a quick look at what you should and shouldn't be eating.
Type O: The Hunter
HARDY DIGESTIVE TRACT
OVERACTIVE IMMUNE SYSTEM
INTOLERANT TO DIETARY AND ENVIRONMENTAL ADAPTATIONS
RESPONDS BEST TO STRESS WITH INTENSE PHYSICAL ACTIVITY
REQUIRES AN EFFICIENT METABOLISM TO STAY LEAN AND ENERGETIC
People with Type O are more prone to gain weight easily, they also will lose weight initially quicker on the ERFYBT diet. This is because the food which doesn't affect other blood types as much, greatly affects the O's. Type O's thrive on intense physical exercise and thus require a greater amount of protein. Unlike the other blood types, Type O's require their muscles to be at a state of slight metabolic acidity. Metabolic acidity is not right for everyone. Type O's also tend to have thyroid regulation problems, specifically having too little of the thyroid hormone. This is why some greens like cabbage, brussel sprouts and cauliflower are bad because they inhibit thyroid production.
Meats and Poultry
Type O's are efficient at digesting and metabolizing meats because of their high stomach acid content. All meats and poulty are ok under the Type O diet. The major thing to be careful though is portion control. For men it should be kept within a 4-6oz portion and women 2-5oz. The reasoning behind this is that meats and poultry are good at bumping our pH into a more acidic state, and while you do want a higher acidic metabolic state, you don't want to overdue it and cause problems like ulcers and stomach lining problems.
Do avoid bacon, ham, pork and quail.
Seafood is the second highest protein packed animal product we can eat. Once again, protein = good for type O's. For type O's of Asian and Eurasian descent, it's especially better because their ancestor's diets were packed with seafood, thus genetically making them more efficient at metabolizing the nutrients. The genetic reasoning for Type O's to eat seafood is because they often have 'thin blood,' meaning they don't have all the genetic factors for clotting blood. The fish oils, even though thought to be blood thinners, are very good for influencing the body into creating a blood 'thickness.' Make sure you once again practice portion control, as everything will be needed in moderation. The most beneficial seafood you can eat are cod, halibut, sole and yellow tail.
Do avoid catfish, octopus and squid
Dairy and Eggs
This might be the toughest one, especially for me. Avoid ALL dairy and eggs. Type O's gain no benefits from eating these products because the body isn't fully equipped, unlike the other blood types, to make them into a proper protein source. You can though substitute soy products for your dairy needs.
Do take daily Calcium supplements, replace milk with Soy Milk and Soy Cheese if you really miss it.
Beans, Nuts, Seeds and Legumes
While nuts and seeds are decent protein sources, they aren't quite enough to make you have to eat them more than you would already be consuming. If you're trying to loose weight then try to avoid them altogether, as they are high in fat. As a Type O, you should avoid certain beans because they inhibit the metabolism of other more vital nutrients. They also lower our bodies acidity, thus pushing us more to an alkaline level when we prefer to be at an acidic state.
Do avoid kidney beans, lentils and tamarind beans.
Do eat flaxseeds, walnuts, black-eyed peas and pumpkin seeds.
Cereals, Breads, Grains and Pasta
No shocker on this one. Basically carbs have been known to be a cause of weight gain since the early 80's, but in case you need reminding, they're a big NO. Type O's can't tolorate whole wheat. Whole wheat contains lectin. Lectin in turn reacts with your blood and digestive tract and inhibits nutrient absorption. It's blocking your body from gaining all the good stuff from the food you eat. Wheat has been shown to be the primary culprit of weight gain in people with Type O. Wheat contains gluten, which interferes with the metabolic process, causing it to slow down and begin storing food, which normally would be absorbed, into fat. If you're like me and sometimes need a carb fix, then replace your whole wheat bread with Essene or Ezekiel bread. This bread is alright because its a sprouted seed bread. The gluten lectins are destroyed in the sprouting process and are a 'live' food with beneficial enzymes. You can find them in the freezer section of your local health food store. Pasta, like whole wheat, contain all that's bad for Type O's so stay clear of them. While yes, all cereals, breads, grains and pastas can cause you to gain weight, there are neutral alternatives you can incorporate into your diet that don't do harm, but at the same time don't boost your body nutritionally.
Do avoid gluten products, wheat and multi-grain bread.
Do substitute Ezekiel bread, ryes, quinoa and soba noodles when you need your carb fix.
Vegetables and Fruits
In general these are good for you under the Type O diet. Although not all veggies and fruits will be good for you. Any veggies from the Brassica family- Brussel sprouts, cauliflower and cabbage- inhibit your thyroid function. This is a problem because Type O's are already weak in the thyroid department. Stay clear too of alfalfa sprouts and mushrooms as they cause a reaction in your body that Type O's are not built to handle. Avoid corn as it contains lectin (covered previously). You are more than ok though from leafy greens like kale, artichokes, broccoli and spinach as they help Type O's function in blood clotting, which as said before, is a problem because of the 'thin' blood which is known to be a problem. Eat fruits as a great way to provide your body with the fiber and minerals you will lack from cutting out carbs. When it comes to picking out fruits, look at their color. The darker hued fruits like plumes, prunes and figs cause an alkaline reaction within your tract and balances out the acidity which the Type O digestive tract tends to have. Avoid highly acidic fruits like oranges and tangerines to not shock your body into a heightened acidic state.
Do avoid corn, cauliflower, mushrooms, olives, avocados, oranges and coconuts.
Do eat artichoke, collard greens, kelp, okra, kale, beet greens, bananas, blueberry, plums and figs.
