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:
“The flattering, if arbitrary, label, First Lady of the Theatre, takes its toll. The demands are great, not only in energy but eventually in dramatic focus. It is difficult, if not impossible, for a star to occupy an inch of space without bursting seams, cramping everyone else’s style and unbalancing a play. No matter how self-effacing a famous player may be, he makes an entrance as a casual neighbor and the audience interest shifts to the house next door.”
—Helen Hayes (1900–1993)
“If the bubble reputation can be obtained only at the cannon’s mouth, I am willing to go there for it, provided the cannon is empty.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“The female of the genus homo is economically dependent on the male. He is her food supply.”
—Charlotte Perkins Gilman (1860–1935)
