More than 60,000 years ago, the first olive tree appeared in Europe and Greece today. In 8000 BC, this olive tree found ancient olive oil in an earthenware pot unearthed in Zipoli, Lower Galilee, northern Israel.

According to the researchers who stumbled across these pots, these olive oil residues can be traced back to 8000 years ago and may have been squeezed by the first olive trees planted by humans.

In 3500 BC, the ancient Greeks began to plant olive trees artificially. Olive tree planting gradually spread from inland to Italy, France, Spain and other places on the northern and western shores of the Mediterranean, BC 1500. Olive oil has become the main cash crop in Crete, Greece, and also an important part of Knossosven civilization in Aegean Sea.

normal requirement

In 2000, China Nutrition Society put forward the reference intake of dietary energy for China residents, pointing out that adult male light and moderate manual workers need 2400-2700 calories a day; The daily energy requirement of female light and moderate manual workers is 2 100-2300 kcal. Babies, children and adolescents, pregnant women, nursing mothers and the elderly have different physiological characteristics and different energy requirements.

deficiency disease

When the daily energy intake of human body is insufficient, the body will use its own energy reserves and even consume its own tissues to meet the energy demand of life activities. People are hungry for a long time. In a certain period of time, the body will reduce basal metabolism, physical activity and weight to reduce energy consumption.

Make the body adapt to energy intake, at this time, energy metabolism moves from negative balance to new low-level balance. As a result, children's growth and development are stagnant, adults are emaciated and their working ability is reduced.

Overexpression

Excess energy will be stored in the body. The storage form of energy in human body is fat, and the abnormal accumulation of fat in human body will lead to obesity, bring unnecessary burden to the body, and may become a risk factor for cardiovascular diseases, some cancers, diabetes and other epidemics.

food source

The energy sources of human body are carbohydrates, lipids and protein in food. These three nutrients are ubiquitous in all kinds of foods. Cereals and potatoes are the most economical food sources because they are rich in carbohydrates. Oil crops are rich in fat.

Animal foods generally contain more fat and protein than plant foods, except soybeans and hard fruits, which are rich in fat and protein, while vegetables and fruits generally contain less.
