For over a year now I've been having very unusual symptoms every time I introduce butter and coconut oil into my diet. I can confidently point the finger at these foods as the symptoms appear literally within the day once I introduce either one of these foods. The physical symptoms include scaling between the eyebrows similar to what's seen in seborrheic dermatitis, however the other symptoms are more subtle like mental fog (though energy wise I feel very stable) as well as pronounced memory loss. I spent about 4-5 months eating grass fed animals with lots of butter and coconut oil thinking that this might simply be 'detox' related symptoms that will go away and experienced quite concerning 'mental blackouts' where I had trouble accessing abstract memory like names, location as well as just general forgetfulness. Once I stop eating these foods and introduce nuts, particularly cashews and macadamia nut oil, my mental wellbeing as well as the ability to recall dramatically improves very quickly and the scaling goes away. I have tried to take a break from butter and coconut oil for 3 months and reintroduce it later but once I did (each at a time, separately), the same symptomology immediately returned.
I am a little confused here. Am I simply allergic/sensitive to these fundamental paleo foods or am I undergoing a 'detox'-like reaction? Is there a reliable way to test for for a sensitivity/allergy to these foods as well as possibly identify tolerable alternatives?
Really appreciate you taking the time,
