While you’re contemplating sugar, it might be a good time to look at carbohydrates in general.
Scientific research shows that smart carbs offer a host of health perks, especially for children. But sorting through the facts about these foods is not an easy task.
First, it’s important to know that all carbohydrate-rich foods are not created equal. Some carbs, such as candy, are just sugar without any redeeming nutritional value; others, such as whole grains, come with good stuff like fibre, vitamins, minerals and an assortment of antioxidants.
Another way to look at carbs that is becoming more and more part of the mainstream is the Glycemic Index (GI). It’s a measure that ranks a food on how quickly the body absorbs it into the bloodstream, compared to a rapidly absorbed carb – either sugar or white bread, which has a score of 100. Evidence is accumulating that a diet high in fast carbs (or a high GI diet) is linked to health problems including obesity, diabetes and later in life, coronary heart disease, certain cancers and even eye diseases.
At a recent international consensus conference called Glycemic Index, Glycemic Load and Glycemic Response, the latest carb research showed that even for kids, choosing smart, or low, GI carbs offers health perks.
- They make you feel fuller, both at meals and then afterwards through the day, defending against obesity.
- They may promote healthier blood pressure readings.
- They can also help fend off type 2 (adult onset) diabetes, which is beginning to show up in teens and tweens, too.
Scientists do not promote banishing quickly digested or high GI carbs altogether. It’s all about balancing low GI foods with high GI foods.
At meals with high GI selections, keep portions in check and add some low GI foods. For example, if you’re serving mashed potatoes at dinner (a high GI food), dish up a smaller scoop and add some chick peas (low GI) to a salad. This is called lessening the glycemic load, a measure which takes into account both a food’s GI, as well as the portion size.
Here are some tips for choosing smart carbs:
Cook your pasta properly. It’s an example of the wisdom of the ages: the traditional way of cooking pasta, al dente — meaning to the tooth — yields a low GI. Overcooked pasta, though, is a high GI food.
Go for intact or longer cooking grains insted of instant or short-cooking ones. For example, large flake or rolled oats have a low GI of around 50, while instant oats have a value of 83. To save time when preparing longer cooking grains, make extra and then freeze portions in labelled containers.
Look for coarse, grainy breads rather than light fluffy varieties. They tend to have higher GIs, even if whole grain. While your kids may turn their noses up at these breads, rotate them with their favourites and over time, they may actually prefer them.
Serve pulses – dried peas and beans which are low GI and fibre-rich. They tend to have higher GIs, even if whole grain. While your kids may turn their noses up at these breads, rotate them with their favourites and over time, they may actually prefer them.
Go for balanced meals. Incorporate small portions of lean protein and healthy fats with smart carbs to lower the glycemic load of the meal.
