Hi S.,
According to Aruveydic medicine, your child is diplaying signs of excess heat. Further, things that come and go are a matter of the liver getting cleansed. Having been at this for a while, I would say that your child needs to strengthen his digestion. Eggs are very sticky to the intestinal track, so I would limit or avoid those. why no fruit? For the sugar? I would introduce blueberries and pomegranate but not necessarily the other fruits. the advice of probiotic was a good one.
As a holistic health counselor, I teach vegetarianism and find many vegetarians can be very acidic because the emphasis is on not eating meat. If the liver needs cleansing then foods like kale, collards, dandelion, and swiss chard should be increased. Further, green beans are great for the liver as is cilantro. Nuts, seeds, whole grains, and dairy are excellent foods but if the system is compromised, these foods should be only 30% of the diet because of their acidity. The rest should be vegetables and fruit with an emphasis on the leafy green ones.
I would also make sure that your house is chemical free. Today's child is so sensitive because their systems are just getting bombarded by chemicals in food, chemicals in the environement, and chemicals in the water. The good news is that all these symptoms show that he needs some change in his system to treat the underlying cause and you are trying alternative practices of dietary restriction and western medicine.
Diet and digestion is just about everything. check out Dr. Douillard at www.lifespa.com. He has written an excellent book for keeping kids healthy that will help you to treated your overheated kid. I have found his work to be invaluable to my practice.
Further, I would highly recommend changing to raw milk products. If you don't live in CT or near a farm, you can get them by signing up with www.westonpricefoundation.com. These raw milk products have the enzymes that help digest them. Personally, I was dairy free for years have been able to re-introduce dairy to my diet.
When my daugther was very sweaty, I also used homeopathic treatments that really helped decrease the sweaty palms and feets.
I wish you the best of luck.
