My wife said something today that made me sit up and think about the oft quoted 'artery clogging saturated fat'.
She said 'Fat is slippery, sugar is sticky; why would fat stick?'
When you pick up a boiled sweet for example, the stickiness is the proteins in your skin being glycated.
When sugar hits the bloodstream, whether via sucrose or digested carbohydrate the body goes into emergency mode and shunts it to glycogen, stored in the muscles or liver, or fat.
Sugar 'sticks' to protein by a process known as glycation. This is deadly - especially if you are diabetic - as excess sugar results in Advanced Glycation End Products( A.G.E.S - which they do!) and inflammation. Over time the immune system will attack the damaged proteins whether cartilage in joints (arthritis) or the coronary arteries (atherosclerosis). That's when big bad cholesterol arrives to try and repair the damage. And thus the cycle is repeated with repeated insult from sugar. (Incidentally sucrose is far worse than digested starch as the fructose half of the molecule glycates protein ten times more then glucose).
In diabetes, a separate subject, the insult of sugar is ramped up to the nth degree and Alzheimers is being called 'type three diabetes!'
Sugar is tightly controlled in the bloodstream, with the average body only having the equivalent of about a teaspoon circulating. A quarter less and you are hypoglycaemic (you'll faint), a quarter more and you are diabetic!
This makes a mockery of 'sports' or 'energy' drinks. People think that drinking that muck will give them an energy boost till it's used up, then go for another top up. Far from it, the body immediately pumps insulin to get it safely stored and you then get a (normal) hypo. It makes me wonder, when I see young girls sucking up Lucozade would drink it were they to know it immediately turns to fat!
Cut out sugar entirely and severely limit easily digested carbohydrate (essentially anything white and refined) go back to eating saturated fat and you will be eating like our big tall ancestors whilst avoiding the absurdity of the current dietary guidelines.
