Let's look deeper at the science behind this statement. Most of the people don't know that digestion happens on 3 levels - in the head, in the stomach and elimination. The second and the third make sense but let's look at the first one. What does it mean that digestion happens in the head?
The beginning of digestion starts with seeing the meal, feeling the smell of it so your mouth starts watering, feeling excited and happy before even starting to eat the meal. If you want to properly digest your food you have to feel taste, pleasure, aroma, satisfaction and the visuals of the meal. This is what scientists call Cephalic Phase Digestive Response (CPDR). Research clearly show that as much as 30-40% of the total digestion happens due to CPDR.
Many people eat in front of the TV and they never even look at their food, they don't smell it, they are not aware that they are eating. Same thing happens when you eat in your car, on your desk while talking on the phone or doing some other work.
So a great advise that will definitely improve your entire digestion, absorption and assimilation of the food is when you eat don't do anything else. Sit, look at your meal and give it the appropriate time and attitude. Food is one of the greatest pleasures we have on the planet. Learn to show gratitude and appreciation, love and respect to it. In return you will feel better and you will get healthier, better looking body.
