How do we determine if a food is healthy?

Of course. if it were to pick food after taste only, than i would be all day at McDonald's(like i used to be :D )

:shock: That is definitely something I cannot understand.
Those things don't even look good (except on their pictures). Even their salads look old and frozen. Yuk.
Seriously, good food is an acquired taste, but once you start learning to enjoy good things, it's impossible to go back to McDonalds. And there are better burgers than theirs, it's not hard... even if they are not the worse, and that, is impressive.

The term "healthy" depends on from where you see and want to talk about.
- If you see from Microbiology, the healthy food means that it doesn't contain microorganisms that can harm your body machinery.
- If you see from Immunology, the healthy food means that it doesn't contain xenobiotics, including pathogens, addictive substances, etc. that can trigger an immune responses.
- If you see from Biochemistry and Nutrition Science, the healthy food means that it should contain at least basal nutrients to keep our body in optimal condition.
- If you see from Physiology, the healthy food means that it should contain materials needed by our body to function properly.
All is correct, it is just different in focus of discussion. It would be a perfect definition if we mix all of them ;)

Hmmm at least for the two first definition, I would say they do not relate to healthy but to "safe". That is how we said when I was working in the National Agency for Food safety. And we all knew how those things are different. A McDonald's menu is usually safe but also quite unhealthy, for example...

I am glad to see this is turning into a McDonald's discussion :D

same as me Andrew.. :D
I think for the safe things, I'll look from immunology that won't activate my antixenobiotic and antioxydant response. But, for the taste, I'll look from Biochemistry and Nutrition Science... :lol:

hethiest food is what you grow yourself or what grows in the place you live at present time of the year. it's best to eat a fruit in 10minutes after you pick it. when you buy food it's impossible to know if it is healthy.

Those interested in what foods are healthy might consider investigating food by blood types especially, in my opinion if you are a blood type O. Dr. D'Adamo divides all foodsinto "Avoid", "Neutral" and "Beneficial" according to 4 primary blood types. Some foods everyone should avoid, some foods are beneficial but many differ from type to type. Clearly this could be a key factor in why people respond to different dietary approaches. For instance, as a Type O I make a particularly sickly vegetarian.

I don't possibly see the relation between blood types and diets. As we know, blood types are given by antigenes on the surface of RBC and no more... Here is a picture of the formation of A and B antigenes from O antigene...(big thanks to the cell bio professor at the national lot for giving us all these wonderful materials...)

So, can you tell us the reasons behind your post, please. I would be fascinated to know...

They say that your diet should be rearranged according to your blood type. But I couldn't think of any reason for that.
If someone know, please explain to us.

I only know the diet for A blood type person [because I'm A type]...do you want the rough explanation? :wink:
