It is important to select ingredients that lead to overall well being." "Carbs should not simply be replaced by using a higher fat or protein content, which lowers GI but may have negative health repercussions. Likewise, the industry won't do itself any favours if it manipulates GI ratings by adding fat or protein, he warns.
While the reformulated product may have a lower GI, he adds, it may also have an ingredients list as long as your arm.
We've used combinations of vital wheat glutens, sodium caseinate, resistant starch and inulin in cookies and cakes." "Sometimes you can't just use inulin, you have to use Hi-maize as well. "Flour replacements for cookie dough and cake batter are different," says scientific and regulatory affairs manager Diederick Meyer. To retain the original texture and flavour of ice cream for example, Danisco Sweeteners has had to replace sucrose with a mixture of polyols, dextrose and fructose for customers keen to develop low-GI varieties.ĭutch ingredients giant Sensus, which has replaced glucose syrups in cereal bars and other products with inulin to reduce their GI rating, says ingredients companies are still learning. Remove it altogether, and products taste and feel very different to the original. If the manufacturing process builds a structure that hinders gelatinisation and enzyme access through using less water, lower temperatures or less pressure, GI will be lower." However, a straight swop replacing sugars and starches with low GI ingredients is not always possible, he warns.įor example, replacing 100% of the sugar in a dessert may not be advisable as sugar has properties such as moisture retention, shelf-life enhancement, texture and bulk. Add more tuna to your pasta ready meal use fruit or oat fibre in your snacks, or change your processes. "There is a multitude of ways to reduce GI. But this doesn't necessarily mean reaching for the artificial sweeteners. If you're not already using these ingredients, reformulate, he says. That is, high-GI foods like sugary snacks rapidly raise blood sugar and release energy quickly but soon leave you feeling hungry again, while low-GI foods like porridge oats release energy more slowly, staving off hunger pangs and making you "feel fuller for longer"Īnd food manufacturers, he contends, have a "tapestry of opportunities" to cash in, both by altering manufacturing processes or reformulating products to reduce their GI.įor a start, there is already a host of low-calorie, low-carb products on the market using ingredients like inulin or fructose to replace easily digestible carbohydrates that could simply be repositioned as low-GI. While the science behind the diet is complex and consumer awareness remains low, its basic premise is simple, insists Jeya Henry, professor of human nutrition at Oxford Brookes University. The issue food manufacturers must address, however, is whether consumers have the faintest inkling of what GI is all about, and whether it is worth pouring hard earned cash into something that might end up in the dustbin of dieting history before the decade is out. The scientists love it, doctors are raving about it and the UK's largest supermarket chain is 110% behind it.
