Hi Christina, I am 16 years old and am a fellow O type, as is the rest of my family. I have been brought up being very health concious and training myself to eat appropriately for my blood type.
Dietwise I am extremely strict and do not eat:
Dairy Products - I substitute with oat milk (not rice milk as it has too much sugar)
Wheat, Yeast and Gluten - I substitute that with kumut or rye bread, sometimes flat rice wraps, rice flour.
Cane sugar - I will always use rice syrup instead of sugar - even in cooking. because it is very low in even natural sugar, and is digested as a food.
I eat a lot of meat, having protein for every meal, but I have a very low fat level in my diet, cutting off most of the fat off my meat & boiling my mince (most people will not have to go to these extremes, but I have a dodgy liver as well) I do this as well as a low carb diet.
I make sure when I excersize, it almost kills me :P I excersize hard and frequently, having 3 days breaks in between in every week (I am on a body-buiding routine) O's need to excersize hard, unlike A's who can do a light walk and get the same resault.
This post is very good & fairly informative, the only thing I can fault you on is on the eggs, I disagree with the comment that O's should avoid eggs as:
Eggs are protein-rich, low in sodium, and contain vitamins and minerals. Some people think eggs are high in bad cholesterol. Cholesterol is actually not a fat. It is a waxy, fat-like substance produced by all animals, including humans. Cholesterol is needed for many bodily functions and serves to insulate nerve fibers, maintain cell walls and produce vitamin D, various hormones and digestive juices. Cholesterol is produced by the liver.
There is a difference between dietary cholesterol (the cholesterol you consume in foods like eggs) and blood cholesterol (the cholesterol in your bloodstream, also called serum cholesterol.)
and because of this view that people have, they will cut out the yolk (which they think will be high in bad cholesterol) but the yolks are the highest source of vitamins in the egg:
With the exception of riboflavin and niacin, the yolk contains a higher proportion of the egg's vitamins than the white.
All of the egg's vitamins A, D and E are in the yolk.
Egg yolks are one of the few foods naturally containing vitamin D.
The yolk also contains more phosphorus, manganese, iron, iodine, copper, and calcium than the white, and it contains all of the zinc.
Thank you for the post.
