A
Nutrition scale is a weighing instrument that output precise nutritional information for foods or liquids. Most scales calculate
calories,
carbohydrates, and
fats, with more sophisticated scales calculating additional nutrients such as
Vitamin K,
potassium,
magnesium, and
sodium.
Scales often use
USDA information on food to ensure accuracy. The products are used primarily as a weight management tool, but have found a user base with
diabetics and
hypertensive people.
