This is an incredibly interesting observation. Thanks for posting it @Hermione.
I definitely have observed a change in preferences for food and drink tastes. Many foods can taste too sweet, ‘sickeningly sweet’. And foods that I once thought bland have developed a pleasant sweetness, such as a rare carrot, or some red capsicum (what do Americans call it?.. pepper).
The main thing I have noticed is an almost synesthetic transformation from ‘tasting food’ in my mouth to ‘sensing food’ through smelling it with my nose. A complete shift from one bodily sense to another.
Especially with wines and foods like cheeses, or recipes cooked with aromatic herbs and spices. I get so much pleasure from smelling the food. It seems to then help me appreciate and savour the offering. In turn slowing my consumption to fully appreciate the sensations. So it has changed how I eat and drink.
These days I don’t drink wine. But if someone opens a nice bottle or two of wine at a social event, my friends understand that I am that strange person that will ask to sniff their wine glass. (How to spot a ketogenic eater?) Sometimes I pour a splash into a large bulb glass and just sniff the wine throughout the meal. I tell the curious onlookers that it is the slowest way to ‘drink’ a glass of wine, using evaporation
.Often if I do taste the wine, it is a let down, as the flavour stands not up to the bouquet.
I still drink coffee. Just in the morning. Coffee is a different experience without milk (or sugar). These days even cream carries enough lactose sweetness to balance the layers of flavour in a good coffee. But I spend a lot of time snuffling the ground, roasted beans. The coffee taste is OK, but not as rich as the bouquet. That roasted bitterness (is it an umami flavour) mixed in the cream is still pleasant.
