I have been experimenting a little bit. I used to have two issues (among others) earlier when I was non-paleo. I used to wake up many times during the night and would feel extremely drowsy during the day. And I would also experience shortness of breath sometimes. After going paleo, these two problems slowly disappeared, with the exception that nowadays I seem to wake up few times in the morning around 6am. Once, I accidentally introduced gluten and the same night I woke up many times. I tried this once again (controlled cheating!) few days back with the same stuff happening again. So here's my list.
- Gluten: Waking up during the night! (though no immediate digestion problems)
- Diary: Shortness of breath! (nowadays I am trying to be paleo+lacto because I keep failing short of calories, but whenever I drink milk or eat yogurt I experience this immediately).
- Rice: Stomach pain due to constipation! (this one's recent and is scaring me).
Note: Sometime back I had to eat rice when my friends had come and was traveling a bit, and slowly I started to get stomach pains. I then cut back all kinds of meat etc, and then started eating rice+yogurt+banana as bland foods. The pain kept going on for 10 days. I finally went to a doc and he told me this point: what happens when rice/bread is put in water? - it absorbs it! That was the reason for my stomach pains! Without realizing it himself, he told me to avoid all the non-paleo food items and he told me I could eat meat/fruits/veggies etc - basically the paleo template. Immediately I went home and prepared some ground beef and ate it even though my stomach was paining - the pain stopped that day!
I think the lesson is to know what exactly happens to your body when you eat food. Share your experiences so others might be able to keep an eye of whats going on with the food and their body!
