Though not a traditional addition to the stew, I like to stir in kale at the end for extra nutrient density and texture, and serve the dish with a sprinkle of roasted peanuts and chopped green onions.
These also sometimes had a raw egg in them for extra nutrient and protein content.
Most of biosorbents are simply available, inexpensive and there is no requirement of extra nutrients.
Subcutaneous fat cells provide an important physiological store of extra nutrients.
You may occasionally feed them tropical fish vitamin supplements, powdered spinach, spirulina, or high quality flake food for some extra nutrients.
One consequence of the demand for increased agricultural food production is the growth in the use of bio-stimulatory products that are marketed on the basis of increasing crop nutrient uptake for a much lower cost than that of extra nutrient application in fertiliser.
If our cows and pigs and chickens are devouring insects, those extra nutrients for them means more nutrition for us as well.
Furthermore, genetically engineered E. coli cells did not require extra nutrients for Ni2+ bioaccumulation.
