Which food especially keeps you awake at night?
I often used to wake up at night with a surge of energy. Almost like an adrenal rush, my body needing to move and restless. It was a horrible feeling. Frequently I would get up, walk around, do some squats or push-ups. It took 20 minutes or more before I got back to sleep.
A friend told me that he and his wife had had the same problem, and found the cause to be raisins. I tried eliminating raisins, not just the couple of handfuls I had as a snack in the afternoon or evening, but eliminating them completely. When I stopped eating raisins, the night time energy surges stopped.
There are other foods that also promote this sleeping problem (insomnia). All high-sugar foods taken in the afternoon or evening can promote these middle-of-the-night energy surges. This includes sweets and lollies, cakes, biscuits, fruit juices, sugar added to foods and drinks, foods made with white flour and sugar, and particularly dried fruits. But there is something about raisins that puts them way ahead of all the other sweet foods that cause these restless legs and muscles at night.
