A wealth of nutrition information is available on the internet. The Micronutrient Calculator gives an indication of average nutrient intakes within the United States population, and does not apply for individuals. There are many online tools available that allow nutrient intake assessments for one person. Here are some links to tools that enable more precise nutrient intake calculations for individuals, and for information about micronutrients.
Nutrition Calculators for Individuals
SuperTracker
SuperTracker is a free tool that allows people to track the foods that they eat, along with other tools that can be used to help maintain a healthy lifestyle. The "Nutrient Intake Report" gives an overview not just on total calories and macronutrients, but also nine minerals, twelve vitamins, and a breakdown of types of fats eaten, including omega-3 fatty acids. It is produced by the US FDA.
