Is it possible to avoid visits to physicians just by consulting Food Nutrients Calculator.com?
Of course not! Browsing Food Nutrients Calculator.com is not supposed to help you replace visits to doctors or nutritionists.
Food Nutrients Calculator.com is aimed at people rather in good shape. It helps them learn about foods according to their nutritional needs. For instance, in order to select the right foods to get more Magnesium, Iron, Calcium, Vitamin C or Proteins; or less Saturated Fats or Salt.
For a given food, the nutritional value for each nutrient may have been measured separately from other nutrients measures, with different scientific protocols, by different labs, and with slightly different foods.
Generally speaking, can one trust nutritional data?
Reading the other answers in this site, you may have noticed that nutrition is rather a "fuzzy" science:
depending on labs, nutritional values of foods vary
depending on countries, nutritional needs vary
depending on the trends, one must drink a lot of water, or just when one is thirsty
Can we then reject all these nutritional data?
Let's say that Food Nutrients Calculator.com is a rule of thumb about what you should eat, and that too much importance should not be given to small details.
Use this website to select foods according to your needs and your tastes, then double check the nutritional data with other websites, with friends or with a physician.
