Considering nutrient levels in different feeds on a dry matter basis (rather than an as-is basis) makes a comparison easier because feeds contain different percentages of water. This also allows a comparison between the level of a given nutrient in dry matter and the level needed in an animal's diet. [10]
Other additives are also used to improve the safety, quality, flavor, and nutritional content of food. [38] Humans obtain most carbohydrates as starch from cereals, though sugar has grown in importance. [28] Lipids can be found in animal fat, butterfat, vegetable oil, and leaf vegetables, and they are also used to increase flavor in foods. [30]

Avocados. If its creamy texture, mild flavor, and use as a breakfast ingredient weren't enough to tip you off, avocado is actually a fruit. If you want to get even more technical, the fleshy fruit ...
Dietary fiber is defined to be plant components that are not broken down by human digestive enzymes. [1] In the late 20th century, only lignin and some polysaccharides were known to satisfy this definition, but in the early 21st century, resistant starch and oligosaccharides were included as dietary fiber components.
