Translate "source" in regards to food

Question

What word other than "fuente" can I describe as a souce of nutrients found in food, e.g. "good source of vitamins and minerals".

Answer 1

This is a tricky question, but I suggest re-phrasing the sentence to say, "The food has many nutrients." This would run something along the lines of "La comida tiene muchos ________," the blank, of course, being whatever nutrients is. I am too lazy to look it up.
