I am Asian so naturally we take photographs of everything ha ha ha ha ha
That said I am not bothered by what other people may think of my food photography habits. If they think that I am wasting time taking food photographs and not enjoying the food/experience, then I could exactly say the same thing about them looking at me, wasting their time looking at me, wondering about me, and discussing about my habits to their friends/family and so on. I am sure there are much better things to be talking about them me
I have taken many photos over the years, and its grown exponentially since the smartphone and social media boom, however no matter where I am - whether it be a food court, through to a San Pelligrino awarded restaurant or in the First Class cabin - I am always mindful of my surroundings and will not take 'snaps' of anything or everything around me just because I can.
A well thought and composed photo will make any trip report or blog so much more interesting. We are very visual people and we all make near-instant judgments and perceptions of things within a split second of seeing it. As for food, it is commonly said that 'we eat with our eyes'. What that means is we form an immediate opinion on how nice a food will taste on it's look and if it doesn't look appealing, we would be reluctant to give it a go - no matter how delicious it actually is.
For trip reports, I prefer not to read a page full of writing if there are no photographs in it. I look at the photos and I can imagine what it was like. Sure the writer could say it tasted fantastic and their taste buds were dancing away for the next three hours, but without the photo - it wouldn't make any sense to me, unless I have tasted the exact same dish before.
Anyway I can understand why some people think that you lose alot of experiences by taking photographs and I see it often, for example people who travel half way round the world only to take a photo of the Eiffel Tower and walk away. Then there's those annoying ones who barge in to take a photo, which ends up photo bombing another dozen people doing exactly the same thing, and then walking away - they have been there, seen it, done it but not enjoyed it.
I might give some photo examples if I have the time today
