In other sources foods serving are 100g; on this website the serving depends on the food. Why?
The nutritional data are much more relevant if given for a portion rather than for a fixed 100g.
Honestly, how can you compare 100g cinnamon, 100g cheese and 100g water? ;) » Back to the question

Is it possible to avoid visits to physicians just by consulting this website?
Of course not!
Browsing rich-foods.com is not supposed to help you replace visits to doctors or nutritionists.
This website is aimed at people rather in good shape. It helps them learn about foods' nutritional values.
For instance, in order select the right foods to get more Magnesium, Iron, Calcium, Vitamin C or Proteins.

Generally speaking, can one trust nutritional data?
Reading the other answers in this page, 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 rich-foods.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.
And most of all, Bon Appétit! » Back to the question
