Sugar is not poison. It’s not even bad for you, especially if it comes from natural sugars in fresh fruit or nonfat milk. It’s the quantity of ADDED sugar we’re eating that’s the problem. A graph of American’s added sugar consumption in the past 150 years looks like the trajectory of a missile. Whereas a person in 1840 sprinkled a scant four teaspoons of sweeteners into home-baked jams and desserts, today the average American heaps somewhere between 29 and more than 50 teaspoons (or about one cup) of sugar onto the daily plate.
A study from the U.S. Department of Agriculture found that two of the top three sources of carbohydrates in women’s diets are regular soft drinks and sugar. In fact, most women are two to four times more likely to reach for a glass of Kool Aid, a doughnut, or a cookie than a whole wheat bagel. Americans consume more than 450 servings per person per year of soft drinks; at five to nine teaspoons of sugar per serving that equates to 2,250 to 4,050 teaspoons of sugar from soft drinks alone. With Americans turned sugar junkies, it is no wonder that more than half of the carbohydrate calories come from added sugar, not whole-grain breads and pasta, in most diets.
Back to your question on whether all that added sugar is bad for us. The only proven harm posed by too much sugar is tooth decay. (Dental caries and periodontal disease have skyrocketed since people began bathing their teeth in a constant supply of sugar.) Granted, many researchers suspect a sugar-laden diet is a culprit in the development and progression of heart disease, depression and mood swings, lethargy, hypoglycemia, diabetes, kidney disease, colon cancer, gallstones, obesity, and ulcers. However, without a consistent trend in the research, no verdict has been reached.
If not a convicted villain, sugar is an accomplice to many health problems, since it either replaces nutritious foods or adds unwanted calories. Let’s face it. Every time you reach for a sugar-laden processed food, you’re missing the opportunity to reach for a chin-dribbling strawberry, crunchy carrot, bowl of split pea soup, or whole grain cereal, the types of foods in which our diets are sorely lacking. When sugar increases above 9% of total calories (we currently are averaging about 15% to 20% of our calories from sugar), people’s vitamin and mineral intakes progressively decrease.
On the other hand, add all that sugar to a diet that is ample in all the foods your body needs to be healthy and you’re likely to tip the scale in favor of weight gain, unless you also exercise vigorously every day. Weight problems, in turn, contribute to the development of cancer, cardiovascular disease, diabetes and osteoporosis.
