I have noticed a creeping trend to speak of "nutrition" when "food" would be a perfectly adequate word. Why is this? Seems like food is a word with many layers of meaning, cultural and affective as well as biological, while nutrition is clinical and without nuance. From my vantage point, using "nutrition" bespeaks an analytical, bloodless and cheerless attitude toward food. Nutrition is what thin rich people want for fat poor people.
It all reminds me of when we gave up sex for gender, and began referring to women as females. Ugh!
