Nutrients Flashcards
Nutrients
Compounds found in foods needed for a healthy life
Macronutrients
Needed in large amounts
Micronutrients
Needed in small amounts
Carbohydrates broken into
Glucose
Protein broken into
Amino acids
Fats broken into
Fatty acids
Monosaccharides
Glucose Fructose Galactose (honey, fruit juices, some vegetables)
Disaccharide
Maltose, sucrose and lactose (sugar and milk)
Polysaccharide
Long chains of multiple monosaccharides, more complex than carbohydrates. Starch, glycogen and cellulose (rice, wheat, corn, pottos, yams, starchy vegetables, and legumes.
Ogliosaccharide
Small number of monosaccharides joined. Promote growth of good bacteria (bifidobacteria) in large intestine. (Breads, cereals, pasta & legumes.
Soluble Fibre
Dissolves in water and forms a gel like substance. Increase satiety, lower ldl, stabilise blood glucose levels, prevent constipation. (Oat bran, barley, nuts, seeds, beans, lentils, peas, some fruits and vegetables.)
Insoluble fibre
is not absorbed during the digestive process. Contributes to satiety helps soften bowel movements. (Wholegrain breads and cereals, nuts, seeds, wheat bran and the skin of fruits and vegetables.
Resistant Starch
Resists digestion in the small intestine and ferments in the large intestine where bacteria changes it into short-chain fatty acids. Helps protect against cancer and reduce cholesterol. (Uncooked pasta, under ripe bananas, cooked and cooled potato, rice)
Amino Acids
20 different amino acids. The body can’t make 9 of these amino acids.
Complete Proteins
Foods that contain all 20 amino acids. (All animal sources and some plants are complete proteins including soy products.)
