Factors such as the type of protein; the proportion of protein, fat, and sugar; the levels of various vitamins and minerals; and the size of the butterfat globules, and the strength of the curd are among those than may vary. For example:
- Human milk contains, on average, 1.1% protein, 4.2% fat, 7.0% lactose (a sugar), and supplies 72 kcal of energy per 100 grams.
- Cow milk contains, on average, 3.4% protein, 3.6% fat, and 4.6% lactose, 0.7% minerals and supplies 66 kcal of energy per 100 grams. See also Nutritional value further on.
Donkey and horse milk have the lowest fat content, while the milk of seals and whales may contain more than 50% fat.

Famous quotes containing the words nutrition and, nutrition and/or health:
“Men have their own questions, and they differ from those of mothers. New mothers are more interested in nutrition and vulnerability to illness while fathers tend to ask about when they can take their babies out of the house or how much sleep babies really need.”
—Kyle D. Pruett (20th century)

“However strongly they resist it, our kids have to learn that as adults we need the companionship and love of other adults. The more direct we are about our needs, the easier it may be for our children to accept those needs. Their jealousy may come from a fear that if we adults love each other we might not have any left for them. We have to let them know that it’s a different kind of love.”
—Ruth Davidson Bell. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
