Our expert says:
I agree with what you say and would not recommend that high protein O blood group diet as a long term solution for anyone. I am personally not convinced that the so-called 'blood diets' are based on sound scientific proof. Why all individuals who have blood type O should be "allergic" to wheat, etc, and that this "allergy" should cause weight gain, does not make sense to me. Your point that anyone eating just red meat and a few vegies (sounds like the Atkins and Prof Noakes rolled in one), may well develop hypertension and other problems, is valid. In addition, all these theorists tend to forget that human beings are omnivores which means that we eat all types of food - meat, fruit, vegetables, nuts, legumes, grains, milk, yoghurt, cheese, and fats, so a balanced diet that contains foods from all the different food groups is more likely to benefit us than a 1 food-group diet. It would be safer for someone with hypertension to use the DASH Diet to lose weight. The DASH Diet was developed in the USA specifically to combat high blood pressure and it can also cause weightloss if required. Click on 'Diet & Nutrition' at the top of this page and then on 'Food as medicine' and 'Hypertension' and read the article about the Dash Diet. You will see that the DASH Diet contains plenty of low-fat or fat-free diary products, fruit, vegetables and whole grains. I don't know what you can do to persuade your hubby to take the sensible course, but do stick to your own convictions so that you do not become ill. Perhaps you can suggest that he should see a registered dietitian (visit the Association for Dietetics in SA Website at: www.adsa.org.za and click on "Find a Dietitian" to find a dietitian in your area), to have his health and this present diet evaluated?
