I have noticed that among philosophers, vegetarianism of one form or another is quite common. In fact, I became a vegetarian (technically a pescetarian) myself partly out of respect for an undergraduate philosophy professor. I am interested in finding out if there is a similar disproportion in the Less Wrong community.
I didn't request that this go into Yvain's survey because I want more information than just what animal products you do or don't eat; I'd also like to see nuances of the reasons behind your diet. There are a lot more shades than carnivore/vegetarian/vegan - if you want to be a vegetarian but are allergic to soy and gluten, that's a compelling reason to diversify protein sources, for instance. I'd also like to hear about if you avoid any plant foods (if you think they're farmed in a way that's environmentally destructive or that hurts people or if you have warm fuzzy feelings for plants, maybe). Here are some questions that come to mind:
- What foods, if any, do you normally avoid for reasons other than pure culinary taste, cost, individual health concerns (allergies, diabetes, etc.) or ease of preparation? (Avoiding foods that are considered revolting or just non-food in your culture of origin, like balut or fried locusts, counts as "culinary taste".)
- What are your reasons for avoiding those foods?
- How strictly do you avoid them? For instance, will you eat them if you are served them while a guest at a meal, or if you are hungry and there is nothing else available? Do you check to see if they're in potentially questionable dishes at restaurants (and if so, do you trust what the server says?)
- If you have children or plan to have children, will you expect or encourage them to avoid the same foods?
- Do you try to convince your friends and family members to make dietary choices similar to yours? If so, have you ever succeeded?
- If you avoid a class of foods with valuable nutritive content (as opposed to Twinkies), what do you replace it with to get complete nutrition?
- What are your attitudes to people who are more restrictive in their diets than you are? Less restrictive?
- What is the timeline of your dietary restrictions? (Transitions, lapses, increases or decreases in restrictiveness, etc.)
- If you have not avoided these foods for your entire life, how much did you enjoy them when you ate them, and do you still sometimes want to eat them?
- Is there anything else about your choice of diet that might be relevant or interesting?
Yes: smell and taste it. If it smells good, eat it. If it doesn't smell good, or if you find yourself wanting to spit it back out (either before or after you swallow), it's bad.
My wife and I have both found that ours bodies are quite sensitive to the scent and taste of raw food; it's easy to tell if something is bad or not. I seem to remember reading somewhere that bacterial counts can be 26 times higher in cooked food than raw, before it's detectable by taste or smell; evidently evolution hasn't had enough time to tune our senses for detecting the quality of cooked proteins!
One other interesting phenomenon I've never seen mentioned anywhere: for lack of anything else to call it, I call it the throat sense. After you swallow something that passes the smell and taste test, but which isn't quite good enough, you'll find an urge to hack it back up from your throat, even though you've already swallowed it.
It's not like throwing up, exactly; it's as if the food just doesn't go all the way down, and you can just spit it right back out again. I think that babies and circus regurgitators make use of the same machinery. But I wasn't aware that I had such a thing, personally, until the first time I swallowed a bad egg that I didn't smell first. (Nowadays, I smell every egg after opening, and I don't refrigerate them. Refrigeration makes them harder to smell, and kept out of the sun, they keep for 2-3 weeks.)
As far as I know, I've never gotten sick from eating a raw protein gone bad, because they don't stay down long enough to reach my stomach. (I did get sick the first time I ate a bad avocado, but I didn't realize yet that it wasn't supposed to taste like that!)
So, as long as you aren't disguising the taste and smell of your food, I wouldn't worry too much about safety. When it comes to raw, if it tastes good, it is good. You can at least trust evolution to get this bit correct. ;-)
Sounds suspicious to me. OK, so maybe if you cook your meat in spices, you can't smell the bugs as easily. But cooking kills bugs, most spices kill bugs, salt stops bugs growing and you don't keep cooked meat for long enough for the surviving, or new bacteria to multiply to dangerous levels. If you had a credible reference for the claim I wouldn't be as suspicious.
