Oats

There are so many different forms of oats porridge available. Is there any significant difference in nutrients between the sachets you just add hot water to and the porridge you have to cook?

Dear Maria
I agree that there are so many different types of oat products on the market these days that it is difficult to make a selection. Basically the instant oat products may have added vitamins and minerals (check on the label), but there can also be a difference in regard to the glycaemic index (GI). According to the latest SA GI & Load Guide, Oats-so-Easy, natural flavour and Oat bran raw by Jungle are low-GI; both raw and cooked oats by Bokomo, Pick 'n Pay, Spar, and Woolworths are medium GI foods; Oat bran cooked, produced by Jungle and cooked Tiger oats, raw Tiger oats, and Jungle Oats-so-easy are all high-GI foods. These differences in the GI are probably caused by the manufacturing process - an oat product that is finely milled will have a higher GI than one that is coarser, because the finely milled product is more easily digested and absorbed, thus causing a greater increase in blood sugar values than the product that is less finely milled.
Hope this helps
