We perceive the world not as it is, but based on our perceived ability to act.
We are all cognizant of the physical constraints obesity places on us physically: degenerative arthritis, metabolic diseases, poor surgical outcomes, body image, depression even. We are less aware of how it subconsciously restrains us from attempting and achieving our aspirations and potential in life.
Fruit sugar may well lie at the heart of our obesity and metabolic epidemic, and this means hypertension, diabetes, dyslipidaemia, gout and cardiovascular disease too.
Perhaps we should start eating healthier by reigning in soft drinks and juicing.
As evident from the earlier "popular press" article I posted, FRUCTOSE has become a convenient bogeyman in the great American obesity epidemic blame game. But what is the scientific basis, if any?
Firstly, looking at the metabolic pathway of fructose in the human body:
fructokinase effectively traps the absorbed fructose in the liver, eventually metabolising it to triglyceride for storage: ie FAT. It is tempting to draw a relationship to it causing fatty liver as well.
Secondly, that first step phosphorylation uses more energy (ATP) than it generates directly, resulting in the generation of uric acid:
thus providing yet another simplistic explanation linking fructose to GOUT.
But truth is never simplistic, and seldom simple, as this article shows. Most of the fructose consumed is converted into energy, glucose, glycogen or lactate, with <1% channeled to TG formation directly. In other studies, the proportion of daily uric acid generation attributable to fructose metabolism appears insignificant. Of course, these experiments do not address whether excessive fructose consumption may tip the balance.
The truth of obesity is, as it always has been: too much consumption (of any caloric source) with too little expenditure (exercise).
