Milk
Types of casein A2 better handled; A1 most prevalent. A2 beta-casein does not cause the same opioid-like reaction as A1 beta-casein.

If you have any reason to suspect dairy foods – pale face, dark circles under eyes, stuffy or runny nose, breathes through mouth, constant throat clearing, another family member reacts to milk, problems with milk as a baby, frequent ear infections, grommets, would live on milk if you let him/her, drinks litres of milk a day, or hates milk, see point 26 below.

Statistically speaking, additives and salicylates are most likely to be the cause of your problems. However, milk can be a problem for many and the introduction of A2 milk (www.A2australia.com.au) has made life much easier for people with food intolerance. It is worth switching to A2 from the beginning because along additive-free bread, it is the easiest of all diet changes to make.
Avoiding Dairy Foods
As well as avoiding milk, you need to avoid yoghurt, skim milk powder in bread and biscuits, icecream, cheese, cream and butter in that order of importance, where milk, yoghurt and milk powder are the most important. Alternatives include soymilk or ricemilk .
Some other soy issues: some people are affected by soymilk as well as cows milk; ingredients change constantly in soymilks and you can be caught by a non-failsafe ingredient, see Checklist of Common Mistakes, and some people worry about possible gender ambiguity effects of phytoestrogens in soymilks in infants and young children. For people avoiding dairy foods, it is probably a good idea to break your diet with small regular amounts of dairy foods such as weekly yoghurt to maintain your lactose tolerance.
