Sugar Cookies

Anyone who's seen the documentary Fed Up knows that sugar consumption has recently been linked to a number of health problems, including weight gain. Leading researchers like Dr. Robert Lustig have compared sugar to poison, urging people to eradicate it completely from their diets. But according to a new study published in the Annals of Internal Medicine, it might be more of an "everything in moderation" situation.

The study, authored by Bradley Johnston from McMaster University, has found that previous correlations are based on "low quality" evidence.

But keep in mind that overindulging in sugary drinks and snacks still isn't a great idea. These products are generally lacking in nutrients and are still high in calories.

"Although our findings question the recommendations from guidelines produced by leading authorities, the findings should not be used to justify high or increased consumption of nutrient-poor, energy-dense foods and beverages like candy and sugar-sweetened beverages," said Johnston.

"We know that it is healthy and advisable to limit our sugar intake," he continued. "The question remains to what degree, and if we are limiting our sugar intake, what are we replacing the sugar with?"

Starches and other food additives often replace sugar, and these products have been known to raise glucose levels and pose additional health risks.

Our conclusion? Everything in moderation, including Christmas cookies.
