Learn the definitions of the most commonly used terms in the health and fitness industry and scale up your vocabulary. A handy glossary that will help you understand all your health blogs, health reports and news articles with ease.


BMI: BMI Body Mass Index: Body Mass Index (BMI) is a person’s weight in kilograms divided by the square of height in meters. BMI screens for weight categories that may lead to health problems, but it does not diagnose the body fatness or health of an individual.

Blood pressure: Blood pressure is the pressure of blood pushing against the walls of human arteries.

Blood sugar : Blood sugar, or glucose, is the main sugar found in human blood.

Cholesterol: Cholesterol is present in every cell of the body and has important natural functions when it comes to digesting foods, producing hormones, and generating vitamin D.

Chronic diseases: A disease or condition that usually lasts for 3 months or longer and may get worse over time. Chronic diseases tend to occur in older adults and can usually be controlled but not cured. The most common types of chronic disease are cancer, heart disease, stroke, diabetes, and arthritis.

Deficiency disease: a disease caused by the lack of an element in the diet, usually a particular vitamin or mineral.

Diabetes: Diabetes is a chronic disease that occurs when your blood glucose, also called blood sugar, is too high. This increase in blood sugar may be because of low or no insulin production.

DNA Fingerprinting
: DNA fingerprinting is a laboratory technique used to establish a link between biological evidence or relation between two organisms.

DNA Sequencing: It is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine.

Fad Diet: A fad diet is a diet that becomes popular for a short time, similar to fads in fashion, without being a standard dietary recommendation.

Fitness Consultant: a trained professional person who provides expert advice regarding someone’s physical fitness and health.

Gene: a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

Gene Pool: the collection of genes in an interbreeding population that includes each gene at a certain frequency in relation to its alleles : the genetic information of a population of interbreeding organisms.

Genomics Glossary The Gene Box Academy

Geneticist: A geneticist is a biologist who studies genetics, the science of genes, heredity, and variation of organism.

Genetics: the study of heredity and the variation of inherited characteristics.

Genomics: Genomics is the study of all of a person’s genes (the genome), including interactions of those genes with each other and with the person’s environment.

Genotype: the genetic constitution of an individual organism.

Gluten Intolerance: A gluten intolerance is the body’s inability to digest or break down the gluten protein found in wheat and certain other grains.

Health : Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.

Healthy lifestyle: healthy lifestyle is a way of living that lowers the risk of being seriously ill.

Hereditary: genetically transmitted or transmittable from parent to offspring.

Heredity: heredity refers to the passing of genetic factors from parents to offspring or from one generation to the next.

Homeostasis: a healthy state that is maintained by the constant adjustment of biochemical and physiological pathways.

Hormonal Imbalance: Irregular levels of hormones produced by the endocrine system of the body.

Immunity: the ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.

Lactose Intolerance: Lactose intolerance is the inability to break down a type of natural sugar called lactose, the main carbohydrate in dairy products.

Macronutrients: Macronutrients are the nutritive components of food that the body needs for energy and to maintain the body’s structure and systems like carbohydrates, proteins and fats.

Metabolism: the chemical processes that occur within a living organism in order to maintain life.

Metabolites: Metabolites are the intermediate products of metabolic reactions catalyzed by various enzymes that naturally occur within cells.

Microbiome: the microorganisms (living things too small to be seen) that exist in a particular environment or in the human body.


Micronutrients: a chemical element or substance (such as calcium or vitamin C) that is essential in minute amounts to the growth and health of a living organism.

Microbes: Microbes are tiny living things that are found all around us. Microbes, or microorganisms, include bacteria, protozoa, fungi, algae, amoebas, and slime molds.

Nutrigenomics: Nutrigenomics is the study of the effects of food and food constituents on gene expression, and how genetic variations affect the nutritional environment

Nutritionists: A person who specializes in the study of human nutrition, especially in the applications of the principles of nutrition in the maintenance of health and the treatment of disease.

Obesity: Obesity is a complex disease involving an excessive amount of body fat that may impair health.

Overweight: above a weight considered normal or desirable.

Pandemic: a disease prevalent throughout an entire country, continent, or the whole world.

Pathogens: A pathogen is usually defined as a microorganism that causes, or can cause, disease.

Personalized nutrition: Personalized nutrition is the concept of adapting food to individual needs, depending on their genetic makeup, lifestyle and environment, the related knowledge and understanding remain fragmented

Physiology: Physiology is the study of how the human body works. It describes the chemistry and physics behind basic body functions, from how molecules behave in cells to how systems of organs work together.

Probiotics: Probiotics are live bacteria and yeasts that are good for humans, especially human digestive system

Shelf life : the length of time for which an item remains usable, fit for consumption, or saleable.

Sustainability: avoidance of the depletion of natural resources in order to maintain an ecological balance.

Symbiotic relationship: Symbiosis is a close relationship between two species in which at least one species benefits.

Therapeutic: relating to the treatment of disease or disorders by remedial agents or methods

Xenobiotics: A xenobiotic is a chemical substance found within an organism that is not naturally produced or expected to be present within the organism.
