Suppose you have a “portion” of potatoes and you remove some; you still have a “portion”
“Significant” is an inherently relative term
In nutrition the reference is usually to an average healthy human adult, but if you want to min/max your returns from what you eat you should learn about the details of micronutrients and macronutrients, physiology, etc and make yourself an optimal serving based on your performance goals
That is to say, whatever you consider significant in any field where a portion is involved, the significance of that portion is only significant as it relates to other objects/portions
