An alginate impression is used in dentistry to make an exact replica of the patientâs teeth, gingiva, and surrounding tissues in the mouth. The alginate dental impression forms an imprint (i.e. a ânegativeâ mould) of those teeth and gums, which can then be used to make a cast or âpositiveâ model of the patientâs dentition. Alginate impression material begins as a powder.
For example, the World Health Organization recommends keeping added sugar intake to 10% of total calories. For the average 2000 calorie-diet that's a maximum of 50 grams. The American Heart Association recommends 6 teaspoons of sugar for women and 9 for men (1 teaspoon of sugar has about 4g of sugar).
Too much sugar is bad for health, but how much is too much? The accepted guideline is that added sugars should not make up more than 10 percent of your total energy intake for the day, although, many nutritionists will recommend even less than this. How much is 10 percent? Well, in a 2000-calorie-a-day diet, 10 percent would be equal to about 50 grams, or 10 teaspoons of sugar. Unfortunately, most Americans consume 30 to 40 teaspoons or more of refined sugar per day. Most of this sugar comes from food products to which sugar has been added, such as soda, candy and baked goods. A can of soda alone can contain around 10 teaspoons of added sugar!
