The Diet Saboteurs: Refined Carbs and Sugar

Bad or simple carbs are the comfort foods we often crave: pasta, fries, pizza, white bread, and sugary treats. Choosing good carbs instead can improve your health, mood, and waistline.

What are refined, simple, or “bad” carbs?

Bad or simple carbohydrates include sugars and refined grains that have been stripped of all bran, fibre, and nutrients, such as white bread, pizza dough, pasta, pastries, white flour, white rice, sweet desserts, and many breakfast cereals. They digest quickly and their high glycemic index causes unhealthy spikes in blood sugar levels. They can also cause fluctuations in mood and energy and a build-up of fat, especially around your waistline.

When you eat refined or simple carbs, your bloodstream is flooded with sugar which triggers a surge of insulin to clear the sugar from your blood. All this insulin can leave you feeling hungry soon after a meal, often craving more sugary carbs. This can cause you to overeat, put on weight, and over time lead to insulin resistance and type-2 diabetes.

Diets high in refined carbs and sugar have also been linked to high blood pressure, heart disease, obesity, hyperactivity, mood disorders, and even suicide in teenagers.

Why is cutting down on sugar and refined carbs so difficult?

For many of us, cutting back on sugary treats and overcoming our carb cravings can seem like a daunting task. As well as being present in obvious foods such as sugary snacks, desserts, and candies, sugar is also hidden in much of the processed food we eat—from soda, coffee and fruit drinks to bread, pasta sauce, and frozen dinners. But cutting back on these diet saboteurs doesn’t mean feeling unsatisfied or never enjoying comfort food again. The key is to choose the right carbs. Complex, unrefined, or “good” carbs such as vegetables, whole grains, and naturally sweet fruit digest slower, resulting in stable blood sugar and less fat accumulation.

By focusing on whole foods and complex, unrefined carbs, you can reduce your intake of sugar and simple carbs, keep your blood sugar stable, maintain a healthy weight, and still find ways to satisfy your sweet tooth. You’ll not only feel healthier and more energetic, you could also shed that stubborn belly fat so many of us struggle with.

 

Good carbs vs. bad carbs

Carbohydrates are one of your body’s main sources of energy. Health organizations recommend that 45 to 65 percent of your daily calories should come from carbohydrates. However, the majority of these should be from complex, unrefined carbs rather than refined carbs (including starches such as potatoes and corn).

Unlike simple carbs, complex carbohydrates are digested slowly, causing a gradual rise in blood sugar. They’re usually high in nutrients and fibre, which can help prevent serious disease, aid with weight-loss, and improve your energy levels. In general, “good” carbohydrates have a lower glycemic load and can even help guard against type 2 diabetes and cardiovascular problems in the future.

Good carbs include:

Unrefined whole grains – whole wheat or multigrain bread, brown rice, barley, quinoa, bran cereal, oatmeal.

Non-starchy vegetables – spinach, green beans, Brussels sprouts, celery, tomatoes.

Legumes – kidney beans, baked beans, peas, lentils.

Nuts – peanuts, cashews, walnuts.

Fruit – apples, berries, citrus fruit, bananas, pears.

Switching to good carbs

While there are many health benefits to switching from simple to complex carbs, you don’t have to consign yourself to never again eating French fries or a slice of white bread. After all, when you ban certain foods, it’s natural to crave those foods even more.

Instead, make refined carbs and sugary foods an occasional indulgence rather than a regular part of your diet. As you reduce your intake of these unhealthy foods, you’ll likely find yourself craving them less and less.

Added sugar is just empty calories

Your body gets all the sugar it needs from the sugar that naturally occurs in food—fructose in fruit or lactose in milk, for example. All the sugar added to processed food offers no nutritional value—but just means a lot of empty calories that can sabotage any healthy diet, contribute to weight gain, and increase your risk for serious health problems.

Again, it’s unrealistic to try to eliminate all sugar and empty calories from your diet. 

You should limit the amount of added sugars you consume to no more than 100 calories per day (about 6 teaspoons or 24 grams of sugar) for women and 150 calories per day (9 teaspoons or 36 grams) for men. If that still sounds like a lot, it’s worth remembering that a can of soda contains up to 10 teaspoons of added sugar—some shakes and sweetened coffee drinks even more.

By becoming more aware of the sugar in your diet, you can cut down to the recommended levels and make a huge difference to the way you look, think, and feel.

How to cut down on sugar

Slowly reduce the sugar in your diet a little at a time to give your taste buds time to adjust and wean yourself off the craving.

Cook more at home. By preparing more of your own food, you can ensure that you and your family eat fresh, wholesome meals without added sugar.

Give recipes a makeover. Many dessert recipes taste just as good with less sugar.

Avoid sugary drinks—even “diet” versions. Artificial sweetener can still trigger sugar cravings that contribute to weight gain. Instead of soda, try adding a splash of fruit juice to sparkling water. Or blend skim milk with a banana or berries for a delicious, healthy smoothie.

Avoid processed or packaged foods. About 75% of packaged food in the U.S. contains added sugar—including canned soups, frozen dinners, and low-fat meals—that can quickly add up to unhealthy amounts. The situation isn’t much better in many other countries.

Be careful when eating out. Most gravy, dressings, and sauces are packed with sugar, so ask for it to be served on the side.

Eat healthier snacks. Cut down on sweet snacks such as candy, chocolate, and cakes. Instead, satisfy your sweet tooth with naturally sweet food such as fruit, peppers, or natural peanut butter.

Create your own frozen treats. Freeze pure fruit juice in an ice-cube tray with plastic spoons as popsicle handles. Or make frozen fruit kabobs using pineapple chunks, bananas, grapes, and berries.

Check labels of all the packaged food you buy. Choose low-sugar products—but be aware that manufacturers often try to hide sugar on labels.

How to spot hidden sugar in your food

Being smart about sweets is only part of the battle of reducing sugar and simple carbs in your diet. Sugar is also hidden in many packaged foods, fast food meals, and grocery store staples such as bread, cereals, canned goods, pasta sauce, margarine, instant mashed potatoes, frozen dinners, low-fat meals, and ketchup.

The first step is to spot hidden sugar on food labels, which can take some sleuthing:

  • Manufacturers provide the total amount of sugar on their labels but do not have to differentiate between added sugar and sugar that is naturally in the food.
  • Added sugars are listed in the ingredients but aren’t always easily recognizable as such. While sugar, honey, or molasses are easy enough to spot, added sugar could also be listed as corn sweetener, high-fructose corn syrup, evaporated cane juice, agave nectar, cane crystals, invert sugar, or any kind of fructose, dextrose, lactose, maltose, or syrup.
  • While you’d expect sugary foods to have sugar listed near the top of their list of ingredients, manufacturers often use different types of added sugars which then appear scattered down the list. But all these little doses of different sweeteners can add up to a lot of extra sugar and empty calories!
