What are added sugars?
Beverages such as soda and fruit drinks are a major source of added sugar in the U.S. diet. Added sugars contribute calories but no essential nutrients to your diet. Dietary guidelines recommend limiting added sugars to less than 10 percent of total calories. That's 200 calories for a 2,000-calorie-a-day diet. Consider that a 12-ounce can of soda has upwards of 100 calories from added sugars.
Is sea salt healthier than table salt?
Despite the fact that sea salt is often promoted as being a healthier type of salt, it has the same basic nutritional value as table salt. In fact, sea salt and table salt contain comparable amounts of sodium by weight. The main differences between sea salt and table salt are in their taste, texture and processing. Whichever type of salt you enjoy, do so in moderation. The Dietary Guidelines for Americans recommend limiting sodium to less than 2,300 milligrams a day.
