18
Q

Gluconeogensis

A

The making of glucose from a non carb source

19
Q

Glycaemic index

A

Ranking of carbs based on how quickly they can be digested and absorbed. Therefore raise blood glucose levels.

20
Q

Glycaemic load

A

The amount of carbs, in grams, in a portion of food that may impact glycaemic response.

21
Q

Glycogen

A

Stored glucose in the liver and muscles. Totals 15 grams glycogen per kg bodyweight

22
Q

Glucogenesis

A

Converting glucose to glycogen

23
Q

Glucose

A

Type of monosaccharide

24
Q

High density lipoprotein (HDL)

A

Good cholesterol. Blood fats that help transport cholesterol out of the arteries and returns it to the liver. Protective against heart disease

25
Q

Hyponatraemia

A

Low blood sodium leading to intracellular swelling. Symptoms include headaches, nausea, vomiting, muscle cramps, swollen hands and feet, restlessness, disorientation

26
Q

Lactose

A

A disaccharide. Glucose and galactose

27
Q

Low density lipoprotein (LDL)

A

Bad cholesterol. Transports cholesterol from the liver to the body tissues. Elevated levels associated with increased risk of heart disease.

28
Q

Maltose

A

A disaccharide of glucose and glucose

29
Q

Minerals

A

Contribute to the structure of bone, teeth and nails. Are a component of enzymes and perform a wide variety of metabolic functions.

30
Q

Monosaccharide

A

Single sugar molecules, glucose, fructose and galactose

31
Q

Monosaturated fats

A

Fatty acids containing one double bond

32
Q

Muscle protein synthesis

A

Process by which new muscle proteins are formed and a muscle grows or repairs ata molecular level.

33
Q

Nutrient density

A

Food based on the nutrient such ad vitamins, minerals and fibre. As well as the healthy plant based compound they provide.

34
Q

Omega 3 fatty acid alpha linolenic acid (ALA)

A

Precursor to EPA and DHA with inefficient conversion process

35
Q

Polypeptide

A

Several amino acids joined together by peptide bonds.

36
Q

Polysaccharides

A

Complex carbs with thousands of glucose units. Most common are starch, fibre and glycogen.

37
Q

Polyunsaturated fat

A

Fatty acids with 2 or more double bonds

38
Q

Protein

A

Primary structural and functional component of every cell in the human body. Used for growth and development and to build and repair cells. Serves as enzymes, transports carriers and hormones.

39
Q

Protein digestibility

A

How much of the protein nitrogen is absorbed during digestion and its ability to provide the amino acids necessary for growth, maintenance and repair.

40
Q

Protein digestibility correct amino acid score (PDCAAS)

A

Measure of protein digestibility or bioavilability that accounts for proteins ability to provide the essential amino acids necessary for the synthesis of body proteins and other metabolites. Does not account for how other compounds within the food alter the bioavailability of proteins amino acids

41
Q

Recommended dietary allowance (RDA)

A

Average daily nutrient requirement adequate for meeting the needs of most healthy people within each life stage and sex

42
Q

Saturated fats

A

Fatty acids with no double bonds and carbon molecules are saturated with hydrogen

43
Q

Sucrose

A

A disaccharide of glucose and fructose

44
Q

Tolerable upper intake level (UL)

A

The maximum average daily nutrient level not associated with any adverse health effects. Intakes above UL increase potential risk of adverse effects.
