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).
How much sugar? Added sugars shouldn't make up more than 5% of the energy (calorie intake) you get from food and drink each day. This is about 30g of sugar a day for those aged 11 and over. Fruit juice and honey can also count as added sugars, as they're sometimes added to foods to make them sweeter. Fruit juice is still a healthy choice (one 150ml serving counts towards your 5 A DAY).
