Energy Obtained From Food
The energy intake from food is limited by the efficiency of digestion and the efficiency of utilization. The efficiency of digestion is largely dependent on the type of food being eaten, while efficiency of utilization is affected by a variety of factors, including age, gender, body weight, hormone levels, and many more.
Chewing, especially in the elderly, has been shown to increase the intake of micronutrients. However, the effect of chewing on the intake of macronutrients, such as sugars, fats, and proteins has not been observed.

“It is the mark of a mean, vulgar and ignoble spirit to dwell on the thought of food before meal times or worse to dwell on it afterwards, to discuss it and wallow in the remembered pleasures of every mouthful.
