Food Intolerance Tests

[TallTony]

I've been thinking for a while about getting a food intolerance test, can anyone make any recommendations?

Groupon sent me a link today for big discounts on the Know Your Body test which makes it a decent price, but its based upon hair rather than blood such as the York Test, which I understand to be highly regarded:

I read somewhere that these tests are not very accurate and it's best to go to your doctors.
Also, any product that is endorsed by "celebrities" always has me viewing it with suspicion.
