The percentage is a mass concentration, so a 5% glucose/dextrose solution contains 50 g/L of glucose/dextrose (5 g per 100 ml). This usage is imprecise but widely used, as discussed at Mass concentration (chemistry) § Usage in biology. Glucose provides energy 4 kcal/gram, so a 5% glucose solution provides 0.2 kcal/ml.
The solution is 9 grams of sodium chloride (NaCl) dissolved in water, to a total volume of 1000 ml (weight per unit volume). The mass of 1 millilitre of normal saline is 1.0046 grams at 22 °C. [ 12 ] [ 13 ] The molecular weight of sodium chloride is approximately 58.4 grams per mole, so 58.4 grams of sodium chloride equals 1 mole.
For added sugars, the guidance is that 100% DV should not be exceeded. 100% DV is defined as 50 grams. For a person consuming 2000 calories a day, 50 grams is equal to 200 calories and thus 10% of total calories—the same guidance as the WHO. [152] To put this in context, most 12-US-fluid-ounce (355 ml) cans of soda contain 39 grams of sugar.
In 2020, the guidance limits added sugars and saturated fats to a maximum of 10% of one's daily calorie intake starting at age 2—a change carried over from the 1990 edition. In Green // Shutterstock
Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk.

The World Health Organization (WHO) describes a homemade ORS with one liter water with one teaspoon salt (or 3 grams) and six teaspoons sugar (or 18 grams) added [1] (approximately the "taste of tears"). [3] However, the WHO does not generally recommend homemade solutions as how to make them is easily forgotten. [1]
These overnight oats get a protein boost thanks to Greek-style yogurt, peanut butter and soy milk, which leads to 17 grams of protein per serving.
Recommended Dietary Allowances (RDA), the daily dietary intake level of a nutrient considered sufficient by the Food and Nutrition Board of the Institute of Medicine to meet the requirements of 97.5% of healthy individuals in each life stage and sex group. The definition implies that the intake level would cause a harmful nutrient deficiency in ...
