Drink your food and eat your drinks.
When we're eating on the run, standing up, watching TV or talking to someone during mealtime this can seriously inhibit digestion and cause all kinds of problems. One of them being inhibiting proper enzyme production which aids digestion.
If you're not producing these enzymes, you're not breaking your food and nutrients down to be absorbed and utilized in the body.
This means being totally present with your meal when you're eating it. Make every meal a sacred event. Chew you're food until it is liquefied and when drinking hold liquid in your mouth for a few seconds without gulping it down.
This enables your body to produce enzymes which aid digestion.
