Characteristics of nutrients

• In nutrition it expresses the power obtained from food
• The unit expressing energy is cal (calorie)
• International organizations use joule
• 1000 cal = 1 kcal
• 1 kcal = 4.18 joule
• * 1 kcal is the energy required to increase 1 kg of water to 14.5 degrees to 15.5 degrees (1 degree)

Function of nutrients

• Source to move the body
• Make the brain function
• Motive force to live
• Lots of activity = Lots of energy consumption
• The balance between activity level and energy is important
• Energy is necessary to maintain life, such as moving organs even when resting
• If you take more energy (carbohydrates or lipids) than the amount used in the activity amount, that amount is accumulated in the body

When nutrients are deficient

• too skinny
• Get tired easily
• Declining thinking ability
• Decreased exercise capacity

When nutrients overdose

• obesity
• Glycosuria

Food that contains a lot of energy

Summary

• Energy is an essential nutrient for living
• It is important to take it in good balance
• The amount ingested changes depending on gender, height, weight, and momentum

Japanese page

Characteristics of nutrients

• It is classified as “insoluble dietary fiber” and “water soluble dietary fiber”
• Insoluble dietary fiber = bowel movement promotion, intestinal action
• Water soluble dietary fiber = Improvement of intestinal bacteria, suppression of blood pressure rise
• The balance between insoluble and water soluble is 2: 1 the best
• It does not become a constituent or energy constituting the body
• Work to drain extra nutrition
• Not digested and absorbed

Function of nutrients

• It has the effect of promoting skin metabolism
• To normalize the mucosa of the skin, throat, nose, gastrointestinal tract
• Prevent diabetes, hypertension, night blindness
• Stimulates intestinal mucosa and promotes laxation (constipation prevention)
• It will drain extra lipid, sugar, sodium etc

When nutrients are deficient

• constipation
• Obesity, diabetes
• Arteriosclerosis, hyperlipidemia, etc..

When nutrients overdose

• There is no need to worry about taking too much with a normal meal
• Very infrequently diarrhea
• Prevent absorption of other nutrients (minerals)

Food that contains a lot of Dietary fiber

Japanese page

Characteristics of nutrients

• It is a generic term for carbohydrates and dietary fiber
• Carbohydrates are digested and absorbed = carbohydrates
• Those not digested and absorbed = dietary fiber
• It will be 4 kcal of energy per gram of carbohydrate
• Since it burns fast, as soon as it is absorbed by the body it becomes energy
• When vitamin B1 is insufficient, it is hard to be absorbed

Function of nutrients

• Become an energy source to move the brain and body
• Only bone, red blood cells, nervous system, muscle, etc. will be energy source
• Activate the brain

When nutrients are deficient

• Become tired easily
• Thinking ability declines
• Muscles weaken
• lose weight

When nutrients overdose

• Extra carbohydrates are stored as body fat
• It causes obesity, diabetes
• Become hyperglycemic

Food that contains a lot of Carbohydrate

Summary

• Generic name for dietary fiber and carbohydrate
• Because it burns quickly, it becomes energy as soon as it is absorbed by the body
• Become immediately energy with vitamin B1 and intake
• Activate the brain

Japanese page

Characteristics of nutrients

• The highest calorie among the three major nutrients
• It is becoming the energy source for moving the body
• It has become a material of the body’s cell membrane and hormones
• It helps absorption of fat soluble vitamins

Function of nutrients

• Cell membranes, nerve tissues, components of nucleic acids
• Helps to absorb fat-soluble vitamins

When nutrients are deficient

• Get tired easily,too skinny,physical strength declines
• Vessels and cell membranes weaken
• Possibility of cerebral hemorrhage
• The absorption of fat-soluble vitamins (A, D, E, K) deteriorates

When nutrients overdose

• obesity
• Diabetes, arteriosclerosis, colorectal cancer, prostate cancer
• Causes of lifestyle-related diseases such as dyslipidemia (hyperlipemia)

Food that contains a lot of Lipid

Summary

• There is no shortage if you eat a normal meal
• There is a possibility of deficiency due to dietary restriction
• It is used for energy, cell membranes, hormones, etc in the body
• It is stored as body fat
• Body fat = used as energy when energy shortage
• It is difficult to absorb fat-soluble vitamins
• A type of fatty acid (linoleic acid or α-linolenic acid) can not be made in the body
• Be careful of taking too much of “invisible oil” contained in sweets, meat, fish etc

Japanese page

Characteristics of nutrients

• There are α-linolenic acid, DHA, EPA
• DHA = docosahexaenoic acid
• EPA = eicosapentaenoic acid
• α linolenic acid is contained in vegetable oil
• DHA, EPA are included in seafood
• Because it is not synthesized in the body, ingest from a meal

Function of nutrients

• Prevention of hypertension, cancer, etc.
• Keep the brain working normally
• Prevent blood clotting and thrombosis
• Reduce bad cholesterol

When nutrients are deficient

• There is no worry of deficiency
• Children rarely have deficiency such as dermatitis

When nutrients overdose

• In the range of daily intake, even if ingested more, there is no harmful effect
• In rare cases, blood becomes difficult to coagulate, bleeding is difficult to stop

Food that contains a lot of n-3 fatty acids

Summary

• It is classified as α linolenic acid, DHA, EPA
• DHA = docosahexaenoic acid
• EPA = eicosapentaenoic acid
• α linolenic acid is a vegetable oil, DHA, EPA is contained in fish and shellfish
• Not synthesized in the body
