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.

Famous quotes containing the words energy, obtained and/or food:
“Just as we need to encourage women to test life’s many options, we need to acknowledge real limits of energy and resources. It would be pointless and cruel to prescribe role combination for every woman at each moment of her life. Life has its seasons. There are moments when a woman ought to invest emotionally in many different roles, and other moments when she may need to conserve her psychological energies.”
—Faye J. Crosby (20th century)
“... how can a rational being be ennobled by any thing that is not obtained by its own exertions?”
—Mary Wollstonecraft (1759–1797)
“Arguably the only goods people need these days are food and nappies.”
—Terence, Sir Conran (b. 1931)
