The need to achieve flawless standards, which can lead to stress and eating disorders.

The tendency to act on whims without considering consequences, which can affect eating habits.

A complex carbohydrate that serves as the stored form of glucose in the liver and muscles.

A hormone produced by the pancreas that lowers blood glucose levels by converting glucose into glycogen.

A hormone produced by the pancreas that increases blood glucose levels by converting glycogen back into glucose.

Norms that promote unrealistic thinness and associate it with positive traits, influencing body image.

The process of taking food into the body, typically via the mouth.

Breaking down food into simpler substances for nutrients absorption.

The process where nutrients from digested food enter the bloodstream.

The process where absorbed nutrients are utilized by the body for energy, growth, and repair.

The removal of indigestible substances from the body, primarily as feces.

The physical breakdown of food into smaller pieces, like chewing.

The biochemical breakdown of food into simpler molecules through enzymes.

Damage to a tooth’s surface caused by bacteria producing acids.

Adverse reactions to certain foods, like dairy or nuts.

A process where water is used to break down compounds.

A process where water is produced as molecules combine.

Organic compounds made of carbon, hydrogen, and oxygen.

Simple sugars that are the building blocks of carbohydrates.

Carbohydrates made up of two monosaccharides.

Large carbohydrates made of many monosaccharide units.

The model describing how enzymes specifically fit substrates to catalyze reactions.
