High-Density Lipoproteins (HDL)

Known as 'good cholesterol', lipoproteins that carry excess cholesterol from the bloodstream back to the liver to be broken down and eliminated, thereby maintaining heart health.

Low-Density Lipoproteins (LDL)

Known as 'bad cholesterol', lipoproteins that deliver cholesterol to cells; elevated levels can accumulate and form plaque in arterial walls, narrowing arteries and raising the risk of heart disease.

Monosaccharides

The simplest monomeric units of carbohydrates ($C_m(H_2O)_n$) consisting of single sugar molecules—specifically glucose, fructose, and galactose—that are soluble in water and absorbable directly into intestinal cells.

Disaccharides

Carbohydrates formed when two monosaccharides bond via a condensation reaction with the loss of one water molecule; examples include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose.

Oligosaccharides

Carbohydrate molecular chains consisting of 3 to 10 monosaccharide units (e.g., raffinose, stachyose); largely indigestible in the small intestine, they undergo fermentation by large intestinal bacteria.

Polysaccharides

Complex carbohydrate polymers comprising 10 or more repeating monosaccharide units, functioning as plant/animal energy stores (starch, glycogen) or structural fibres (cellulose, inulin).

Glycaemic Index (GI)

A relative ranking scale ($1\text{--}100$) reflecting the rate at which carbohydrate-containing foods are digested, absorbed, and convert into blood glucose relative to pure glucose or white bread.

Low GI Foods

Carbohydrate-rich foods with a glycaemic index rating less than $55$, which break down slowly, producing a gradual, sustained blood glucose rise and requiring less immediate insulin.

Diabetic Ketoacidosis (DKA)

A severe acute metabolic complication of diabetes characterized by dangerous accumulations of ketones and glucose in the blood, leading to acidosis and organ dysfunction due to insufficient cellular insulin.

Gluten

An elastic protein matrix formed by the hydration and mechanical alignment of gliadin (globular protein) and glutenin (elongated strands) found in wheat, rye, and barley.

FODMAPs

An acronym for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols; short-chain carbohydrates resistant to small-bowel digestion that ferment rapidly in the colon, triggering gastrointestinal distress in sensitive individuals.

Gelatinisation

The thermal breakdown of intermolecular bonds within starch granules in the presence of water ($60\text{--}100^\circ C$), causing granules to swell, absorb liquid, rupture, and form a thickened gel.

Dextrinisation

A non-enzymatic chemical browning process occurring when dry heat breaks down starch polymers into shorter carbohydrate fragments called dextrins, altering colour, aroma, and flavour.

Caramelisation

Monounsaturated Fatty Acids (MUFA)

Fatty acids possessing exactly one carbon-to-carbon double bond ($C=C$) along the hydrocarbon chain, creating a structural kink that keeps them liquid at room temperature.

Polyunsaturated Fatty Acids (PUFA)

Fatty acids that feature two or more carbon-to-carbon double bonds within their hydrocarbon backbone, encompassing essential omega-3 and omega-6 fatty acids.

Trans Fatty Acids

Unsaturated fatty acids featuring trans-configured double bonds, produced industrially via partial hydrogenation of vegetable oils, which elevate LDL cholesterol while reducing beneficial HDL cholesterol.

Dietary Fat Energy Density

The quantitative physiological energy value of dietary lipids, yielding $37\,kJ$ of energy per gram, which is more than double that of carbohydrates or protein ($17\,kJ/g$).

Plant Sterols

Naturally occurring plant compounds that structurally resemble cholesterol; daily intakes of $2\text{--}3\,g$ inhibit intestinal cholesterol absorption, reducing total blood cholesterol by approximately $10\%$.

Body Mass Index (BMI)

A standardized population measure of body size and morbidity risk calculated as weight in kilograms divided by height in metres squared ($\text{kg/m}^2$), classifying individuals as overweight ($\ge 25\,\text{kg/m}^2$) or obese ($\ge 30\,\text{kg/m}^2$).

Abdominal Obesity Thresholds

Type 1 Diabetes

An autoimmune condition in which the immune system targets and destroys insulin-producing beta cells in the pancreas, resulting in complete endogenous insulin deficiency requiring lifelong insulin therapy.

Type 2 Diabetes
