One way to automatically ramp up your digestion and lower your stress is to do a short breathing exercise before every meal.
Inhale through your nose and exhale through your mouth.
Repeat this 10x before you begin your meal.
Doing so will allow your system to calm down and relax, which will assist you in digesting your food well.
Believe it or not, your stress/anxiety levels have a lot to do with how well your body digests food. This is an easy way to lower those levels right before you begin eating. Try doing this before every meal and see what feels different for you!
