All food contain natural sugars !
Sugar is Sugar Malcolm no matter where it resides. The chemical formula is the same so the concept of "Natural Sugar" is a bit of an urban myth. There's another post that explains all this here:
http://www.over50sforum.com/showthre...ructose&page=5
The basic "simple sugars" are as follows (with their chemical formulae):
Glucose - a Monosaccharide - C6H12O6
Fructose - a Monosaccharide - C6H12O6
Galactose - a Monosaccharide - C6H12O6
The formula means they have 6 Carbon atoms, 12 Hydrogen atoms and 6 Oxygen atoms). They differ only in the specific arrangement of those atoms.
Then we also have:
Lactose - a Disaccharide - C12H22O11
Sucrose - a Disaccharide - C12H22O11
Maltose - a Disaccharide - C12H22O11
Disaccharide basically means these molecules have 2 sugars in them which is why the chemical formula is double that of the simple sugars. They break down as follows:
Lactose = glucose + galactose
Sucrose = glucose + fructose
Maltose = glucose + glucose
All of which is largely academic. What actually matters when we are talking about eating sugars, is HOW we eat them or rather WHAT we eat them with.
If we eat sugars on their own, then the body converts them to energy really quickly (which gives us the buzz and blood sugar rush), but since the body has no use for that energy supply at that time, it then stores it as fat.
If on the other hand we eat sugars in combination with a lot of fibre, then the body takes a long time to convert that sugar to energy and that means the energy is generally used up for the body's continual needs like pumping your heart, breathing, walking etc etc.
So, food products that are all sugar and little or no fibre are very bad for us and will quickly make us fat. Obvious candidates are sweets, cakes, pastries etc. All fat and sugar and no fibre.
But there are a plethora of less obvious foods too.
Basic fruit juices like "Freshly Squeezed Orange Juice" (which is anything but by the way - likely at least a year old) are basically all the sugars from the fruit with most of the natural fibre taken out. So a bad thing.
A single large apple has 4-5 teaspoonfuls of sugar in it. But because the flesh and skin all have lots of fibre, when you eat it, you are eating sugar and fibre combined so all is well.
A typical large 500g pot of low fat natural yoghurt has approx. 9 teaspoonfuls of sugar in it. At the same time it has no fibre. So what most people think of as a great healthy food to have on a diet, is actually loading them with sugars with no fibre ! No wonder many people struggle to lose weight. They are being duped at every level by large food manufacturers who are creating products that have high sugar content (natural or otherwise) and which have no corresponding fibre.
Anyways, plenty to research in all this.
