She adds, "Agave syrup has a low Glycemic Index (GI) score - a measure of how quickly the sugar in a food enters your bloodstream - because of its low glucose content. But this is irrelevant as agave syrups are dangerously high in fructose content, often as high as 90 per cent.
"In this way, agave syrup is similar in composition to high fructose corn syrup, which is a processed sugar common in the US and is thought to be largely responsible for much of the country's obesity epidemic."
Another type of food which people eat thinking they're being healthy are low-fat yoghurts, but it turns out they have a very high sugar content. Rhiannon says, "low-fat, sugar-sweetened yogurt contains too much sugar to qualify as a nutritious choice. Many types of low-fat and non-fat yogurt are as high in sugar as desserts. Stick to Greek yoghurt and add fruit for flavor." Also on the dairy side of things, she says to drink full fat milk instead of low fat as "it is perfectly healthy as the higher the fat content, the slower the release of intrinsic lactose sugars." There's bad news for those who love to snack on protein bars, they're a big no-no for Rhiannon. She says, "these bars are labeled as a healthy, low-sugar, low-carb treat or dessert, but they contain sucralose, an artificial sweetener made from sugar in a multi-step chemical process where three hydrogen-oxygen groups are replaced with chlorine atoms."Research suggests sucralose raises blood sugar levels, making us hungry when levels crash - and that contributes to weight gain."
