You know, Primal30 might be a good start. I do think that getting him off dairy would be beneficial as well, but I don't know what the benefits would be. His sister is lactose intolerant, so I wonder if he could be as well. He doesn't have any acne or eczema and doesn't seem phlegmy, so if he's got any intolerances to dairy, it will likely be digestively. I get phlegmy and break out when I consume too much dairy.
Speaking of which, I will be sticking, for the most part, with the whole30 rules and allow for some dairy maybe once a week or so. There are some recipes that our family loves but they contain parmesan cheese and cream. We're not willing to give them up permanently, so maybe one a week would be ok.
Not planning to do a 21 day sugar detox at this point. I think the extra 18 days on the whole30 helped me ward off the sugar addiction. I haven't dove face first into sugar. Normally I would have already made a ton of different sugar containing snacks and devoured them. I'm quite surprised. I did have some of mom's refrigerator pickles though (cucumbers, onion, vinegar, water, sugar). They were good. I will have to see if I can make some with honey instead of refined sugar.
