Various methods of preserving milk include pasteurizing, dehydrating, evaporating, condensing and canning.
The nutritional qualities of milk are claimed to depend on the diet of the cattle, with grass-fed cattle producing milk with healthier fats.
Grain-fed cattle have a high ecological footprint, requiring large areas of land to produce the grain. Such practices increase the demand for grains, and thus food prices and food security, especially in developing countries.

Notes and references
- The impact is greater in developing countries and particularly the foods purchased by the poorer segments of those countries, because the price of basic foodstuffs makes up a greater proportion of the price of purchased foods. Non-grain foods are not directly affected, but the demand for land to produce food for livestock will indirectly increase the price of all foods.
