Fruits and vegetables are 70 to 95% water. Most meats are on average about 70% water. Breads are approximately 36% water. [3] Some foods have a water content of less than 5%, e.g., peanut butter, [3] crackers, and chocolate cake. [4] Water content of dairy products is quite variable. Butter is 15% water. Cow's milk ranges between 88 and 86% water.
Plant nutrition is a difficult subject to understand completely, partially because of the variation between different plants and even between different species or individuals of a given clone. Elements present at low levels may cause deficiency symptoms, and toxicity is possible at levels that are too high.
Scientific analysis of food and nutrients began during the chemical revolution in the late 18th century. Chemists in the 18th and 19th centuries experimented with different elements and food sources to develop theories of nutrition. [1] Modern nutrition science began in the 1910s as individual micronutrients began to be identified.

Eating a diet high in fruits, vegetables, grains, legumes and plant-based beverages has long-term health benefits, [17] but there is no evidence that taking dietary supplements of non-nutrient phytochemicals extracted from plants similarly benefits health. [4]
In horticulture and agriculture along with food science, plant physiology is an important topic relating to fruits, vegetables, and other consumable parts of plants. Topics studied include: climatic requirements, fruit drop, nutrition, ripening, fruit set. The production of food crops also hinges on the study of plant physiology covering such ...
Botanically, a fruit is defined as the part of a plant that matures from the flower and contains seeds. So, if a plant part grows from the flower and holds seeds inside, like bell peppers and ...
