Supports Chapters 8: Why 'five portions', and Chapter 21: Diseases of the heart and blood vessels
Dr Hans Selye first proposed that stress may be a cause of heart attacks back in 1950. There is now a considerable body of evidence to support this hypothesis, but the mechanism has been obscure.
There is also a hypothesis that a low pH in the blood (denoting acidity) increases cardiac risk. So we are told to avoid eating 'acid forming' foods such as meat, fats and dairy, and eat more 'alkaline foods' such as fruit and vegetables.
A recent hypothesis by Dr Carlos Monteiro in Brazil may have the answer - and it turns current acid/alkaline foods hypothesis advice on its head.
We have lived by eating meat and its 'saturated' fat for the whole of our existence as a species; ischaemic heart disease, against which 'healthy eating' is targeted, only 'took off' in the 20th century. The idea that our traditional diet should suddenly become the cause of this modern disease is a fraud and a delusion. Yet it is the sole basis for the current paradigm. It is also the basis for the 'acid/alkaline' theory.
But there is an acid that can lower pH in the blood and cause harm, and that is lactic acid. It’s not ingested lactic acid but produced by the body in response to stress. We live now in stressful times, where our 'fight-or-flight' reflex must be working overtime. A principal result of such stresses is increased levels of lactic acid in the blood.
A 'healthy' diet of glucose, fructose and other sugars from carbohydrates also raises blood lactic acid as a by-product of the metabolism of glucose for energy from dietary carbohydrates. The worst of these is the fruit sugar, fructose, which increases blood pressure and other heart attack risk factors.
If a low-carb, high-fat diet is adopted, that naturally reduces lactic acid production from anaerobic metabolism of glucose by increasing aerobic metabolism of fats for energy.
