Biology in Healthcare 2 Flashcards
Nutrition
Set of biological, psychological and sociological processes involved in the obtaining, assimilation and metabolism of nutrients by the body
Set of biological, psychological and sociological processes involved in the obtaining, assimilation and metabolism of nutrients by the body
Nutrition
This is possible thanks to nutrition
Eating food, digesting food, absorbing nutrients, and taking advantage of them
Metabolism
Series of reactions that allow organisms to be built, degraded, and transformed
Series of reactions that allow organisms to be built, degraded, and transformed
Metabolism
Process by which food is obtained, to later take advantage of its nutrients
Feeding
Feeding
Process by which food is obtained, to later take advantage of its nutrients
Food
Any substance that the body canassimilate and use for its vital functions
Any substance that the body canassimilate and use for its vital functions
Food
Nutrient
Chemical substance found in food; it serves the body energy to supply itself, perform its functions and form tissues

Nutrient
Goals of optimal eating in adolescence
Adeuqate supply of energy and nutrients, avoid imbalances, and prevent diseases
Purpose of adquate supply of energy and nutrients while eating during adolescence
Optimal growth and development
How to obtain optimal growth and development
Get an adequate supply of energy and nutrients
Aspects that influence an adolescent’s diet
Increased energy demand, psychological changes, and biological risk factos, such as eating disorders and drugs
Reasons adolescents have increased energy demand
Growth, sexual maturity, increase in height and weight, accumulation of skeletal mass, changes in the composition of fat and muscle mass
Variables that affect that amount of energy that each person requires
Gender, physical activity, growth speed, amount of and and muscle, etc.
Uni of measurement used to measure energy found in food
Calorie
Calorie (cal)
Amount of heat or energy necessary to raise the temperature of 1g of water by 1°C
Amount of heat or energy necessary to raise the temperature of 1g of water by 1°C
Calorie (cal)
Kilocalorie (kcal)
Amount of heat or energy necessary to raise the temperature of 1 kg of water by 1°C
Amount of heat or energy necessary to raise the temperature of 1 kg of water by 1°C
Kilocalorie (kcal)
Energy consumption recommendations for the general population
Recommended Daily Intake (RDI)
Recommended Daily Intake (RDI)
Energy consumption recommendations for the general population
Good Eating Habits
Don’t skip any meal times, select healthy food, follow diets planned by professionals, exercise, take responsibility for eating
Effects of skipping meals
Negative effect at the cognitive level, impact on health and possible weight gain
Characteristics of unhealthy food on the street
High staurated fat and sugars; poor in fibers
Types of nutrients (2)
Macronutrients and micronutrients
Macronutrients
Nutrients required in large quantities. They provide energy and form new structures.
Nutrients required in large quantities
Macronutrients
Micronutrients
Nutrients required in small quantities. They participate in the defense system and metabolic pathways
They provide energy and form new structures.
Macro nutrients
Nutrients required in small quantities
Micronutrients
They participate in the defense system and metabolic pathways
Micronutrients
Types of macronutrients
Carbohydrates, protein, lipids (fats)
Types of micronutrients
Vitamins and minerals
Proteins are formed by
Aminoacids
Purpose of proteins
Growth of cells, tissues, and organs They give us energy Help with metabolism Muscular contraction Develop antibodies
Purpose of fats
They give us energy
They are essential for growth and health
Types of fats
Saturated, mono-saturated, and poli-saturated
Sources for saturated fats
Red Meat Fat Bird Fat Sausages Whole Milk Cheese Butter
Sources for mono-saturated fats
Olive oil, dried fruit, peanuts, avocado, sesame seeds
Sources for poli-saturated
Fish, fish oil. nuts. sunflower seeds, soybean, flax oil
Result of decomposition of carbohydrates in the liver
Glucose or sugar
Purpose of carbohydrates
Supplies energy to the brain and nervous system
Forms in which carbohydrates are found
Sugar or saccharose, starch, fiber
Places where sugar or saccharose are found
Fructose, glucose, lactose, galactose, maltose
Fructose
Sugar in fruit
Glucose
Sugar in blood
Lactose
Sugar in milk
Galactose
Sugar in vegetables
Maltose
Sugar in cereals and barley
Sugar found in fruit
Fructose
Sugar found in blood
Glucose
Sugar found in milk
Lactose
Sugar found in vegetables
Galactose
Sugar found in cereals or barley
Maltose
Places where starch can be found
Cereales, tubercules and legumes
Places where fiber can be found
Cellulose, pectins and gums
Main source of energy in diets
Carbohydrates
Cal/g of carbohydrates
4 cal/g
Place in which excess carbohydrates are stored
Adipose tissue (fat)
Fiber
Non-digestible carbohydrates with beneficial functions in GI and prevention of chronic diseases
Non digestible carbohydrate with beneficial function in the gastrointestinal tract (GI)
Fiber
Sources for carbohydrates
Fruits, vegetables, cereales, legumes, bread, tortillas, pasta, sweets, honey
Cal/g found in proteins
4 cal/g
Cal/g found in lipids
9 cal/g
Preferrable origin of fat and reason
Vegetable origin, since they have unsaturated fatty acids and lack cholesterol
Vitamins
Organic compounds that the body needs in very small amounts for certain chemical reactions to take place
Organic compounds that the body needs in very small amounts for certain chemical reactions to take place
Vitamins
Processes that use vitamins
Defense system and proper development and growth
VItamins that can be obtained from bacteria in the large intestine
K and B12
Types of vitamins
Fat-soluble and water soluble
Examples of fat-soluble vitamins
A, E, D, and K
Vitamins A, E, D, and K are examples of
fat-soluble vitamins
Examples of water-soluble vitamins
