Sugar: The bitter truth!

Conditioning Research: Lustig - Sugar the bitter truth

In a nutshell for those who are not familiar with what eating sugary foods does to the body and the effects it has on OBESITY in MEN, WOMEN & CHILDREN please read on . . . . .

Our body has 2 hormones that have to work TOGETHER to transport fuel to the muscle to be used for energy, Insulin & Glucagon. (lets think of them as 2 taxi drivers)


When blood glucose gets too high the pancreas works hard to regulate this spike by releasing insulin and other regulating hormones. When this happens, our other taxi driver glucagon can't transport fat to the muscle for energy. 

  
Glucose will be brought to the liver and muscles to replenish glycogen used during exercise. Excessive blood glucose can also be taken up by fat cells and stored as adipose (fat) tissue!



GLYCEMIC INDEX
Depending on the speed of conversion to glucose, all carbs can be placed on a scale between 0 and 100. This scale is known as the Glycemic Index (G.I.)


Complex Carbs = Slow releasing = Low G.I. 



Brown Rice
Potatoes
Other root vegetables
Wholemeal breads
Granary bread

Simple Carbs = Faster releasing = High G.I.


Table Sugar
Fruit Juice
Sweets
Bread made with white flour
Pasta made with white flour



We only want an increase in blood sugar straight after training and not, for example, on a non-gym day when there is simply no need for a massive sugar rush!
 Stick to the complex carbs and maybe post workout quick release food to replenish the energy quickly!

 I want to use white bread as an example. This highly processed food is high G.I., low in fibre, proteins and good fats - boo!


White bread ----> Easy to eat - - -> Digested quickly - - -> Sugar spike - - -> Insulin released - - -> Excess energy stored as fat - - ->  Sugar levels drop - - -> Carb cravings - - -> Cycle repeats - - -> Fat gain!

Supermarket domination?



What's your opinion?




I mean don't get me wrong, I still go to supermarkets for bits and bobs but these billion dollar companies like Tesco, Asda, Sainsburys just seem to be popping up all over the show. Not to mention they are all English!!

Back in the mid 80's there would have been typically a few butchers, fruit and veg and bakeries lined the streets. Now we have very little.
Tesco's opened up a supermarket in Crumlin down the street from my cousin's butcher shop. Thankfully no damage has been done. Tesco's 'meat display' looks something like Lady Ga Ga would wear on a night out . . . needless to say the meat is crap at best. They don't hang the meat to give it maturity or flavour. They pre pack it and fire it out on the shelves and I can guarantee the meat will be as tough as old boots. Anyhow - my rant is over. I urge you to support your local farmers/butchers and tradesmen as Tesco would say . . . "Every little bit helps!"




I mean if that doesn't make you hungry I don't know what will!
