Done right, snacking can keep hunger at bay, fuel your energy levels, and provide a great source of health-boosting nutrients. Done wrong, snacking can leave you feeling tired, sluggish, and hungrier than before, as well as fill you up with empty-calories that don't satisfy you at all.
And while we all know of the obvious culprits to avoid, these seemingly "healthy" snacks are actually not as virtuous as originally meets the eye.1. Bottled green juices
While it's nice to think you're getting your five-a-day in one drink, the reality is that you're actually consuming huge heaps of sugar. And although it's from a natural source, with all the fiber of the fruit and veggies removed when they're juiced, this sugar will still hit your bloodstream like a bag of sweets.
Instead choose a piece of fruit or some raw vegetables such as carrots, cucumber, or celery. The fiber they contain will both slow sugar release and help to sustain energy levels. Team fruit with yogurt or nuts, and veggies with a dip such as hummus or tzatziki for some hunger-zapping protein.2. White rice cakes
They've long been touted as a "diet food," thanks to their low calorie content and zero fat, but anyone who has relied on them while dieting will know that they do absolutely nothing to fill you up. They also have a very high GI (glycemic index), meaning the carbs they contain become absorbed into your bloodstream very quickly, sending your blood sugar on a rollercoaster. This spells bad news for energy levels, hunger pang, and weight loss in general.
Instead choose oat cakes, which are higher in fiber, vitamins, and minerals, and are made from the wholegrain so have a lower GI and won't upset your blood sugar as much. Combine with a source of protein such as nut butter or cottage cheese.3. Energy/protein bars
These make a convenient on-the-go snack, but some brands actually contain as much sugar (if not more) than a typical chocolate bar. Don't assume that labels such as "natural" or "raw" automatically equate to "good for you." These bars are often packed with dried fruit, honey, and other syrups, which are all forms of sugar, thus high in calories and will drive your desire for more sweetness.
Instead choose a handful of raw nuts. Protein is satiating (it fills you up), and also regulates blood sugar levels and helps to avoid sugar cravings.
4. Diet Coke
Diet drinks are free of sugar, but instead contain artificial sweeteners such as aspartame, which, gram for gram, can be up to 13,000 times sweeter than sugar. Regularly consuming these sweeteners can increase your cravings for sweet stuff by sending the same messages to your brain as sugar does, and this can actually lead you to eating more sugary snacks throughout the day. They might be labelled "diet," but conversely some studies suggest that artificial sweeteners can contribute to weight gain.
Instead choose still or sparkling water, and infuse it with fresh fruit (orange, lemon, strawberries, and mint) for flavor.
Fats in yogurt taste really good, and when it's removed from a product, food manufacturers know that they need to replace it with something else to make the food palatable. This something else is usually sugar. As an example, a small pot of low-fat lemon yogurt can contain 23g sugar—the equivalent of almost six teaspoons. And while about 10g of that comes from the milk itself, that's still over three teaspoons of added sugar in what is considered a "healthy" snack.
Instead choose plain, probiotic yogurt and add your own fresh fruit for sweetness6. Bag of dried fruit
This seems like the healthy snack of choice—it's fruit, after all! But you wouldn't sit down to an entire pack of dried mangoes, would you? And yet it's very easy to eat 10 (or even more) pieces of dried mangoes in one sitting. While dried fruit is ok in small amounts, it's easy to eat quite a lot of it—and this provide a big hit of sugar. In addition, some dried fruit has added sugar and preservatives.
Instead choose a bag of trail mix, which combines a little bit of dried fruit with mixed nuts and seeds. Higher in protein, less sugar, and will keep you fuelled for longer.
7. Vegetable chips
Don't be duped by the word "vegetable" in their title. In terms of calories and fat, these are pretty much in the same ball park as regular chips. Veggie chips are usually deep-fried in oil, just like their seemingly unhealthier counterpart, meaning that they are high in saturated fat—and also have lots of added salt. And once the veggies are processed into chips, many of their vitamins and nutrients have been destroyed anyway.
Instead choose a large handful of fresh edamame peas, which are rich in protein so will help keep you full, without overloading on calories.
