NUTRITION CERTIFICATION COMPREHENSIVE
EXAM 2026 COMPLETE QUESTIONS WITH
ANSWERS
◉ Whey Protein. Answer: Whey protein concentrate is the liquid
fraction of milk and is typically about 80% protein with small
amounts of carbohydrates, fat, and lactose.
◉ Lactose. Answer: A naturally occurring sugar present in milk and
milk products.
◉ Casein Protein. Answer: Casein makes up 80% of the protein in
milk. Although it is a complete protein source, it contains less
leucine and is insoluble in acid, forming clots in the stomach acid,
thereby leading to slower digestion and absorption. As such, casein
protein supplementation has been shown to stimulate MPS to a
lesser extent than whey protein supplementation and leads to lower
resistance-training-induced gains in lean mass
◉ Plant Protein. Answer: Plant-based protein supplements are
growing in popularity and are often composed of one or more
protein sources from soy, peas, rice, and others. In terms of
stimulating MPS, soy protein has been shown to be inferior to whey
and casein due to lower leucine content, fewer essential amino acids,
and lower bioavailability
,◉ Bioavailability. Answer: The extent to which an ingredient, food,
or other substance is absorbed by the body.
◉ Acceptable Macronutrient Distribution Range (AMDR). Answer: A
range of intakes for carbohydrates, protein, and fats set by the Food
and Nutrition Board of the National Academy of Medicine
recommended to meet the nutritional needs of most individuals and
reduce risk of chronic disease.
◉ HMB (Hydroxy-Methylbutyrate). Answer: Hydroxy-
Methylbutyrate is a byproduct of the essential branched chain amino
acid, leucine, identified as the primary initiator of muscle protein
synthesis.
◉ Caffeine. Answer: Caffeine (1,3,7-trimethyl-xanthine) is a
naturally occurring substance in coffee beans, kola nuts, guarana
seeds, yerba mate, and tea leaves, and it is also synthesized in a lab
as caffeine anhydrous. It stimulates the nervous system and has
been shown to modestly increase daily energy expenditure, decrease
energy intake, reduce perceived-effort-level of exercise, and improve
feelings of energy and alertness
Low to moderate doses of caffeine at 3 to 4 milligrams/kilograms of
body weight, not to exceed 400 to 500 milligrams/day
,◉ Capsaicin. Answer: Capsaicin is one of five naturally present
capsaicinoids in red chili peppers and is purported to be a natural
weight control due to its ability to stimulate thermogenesis, increase
body temperature, and decrease food intake
Capsaicin may have a slight positive impact on energy expenditure,
appetite, and food intake when consumed in 2- to 4-milligram doses
before meals.
◉ Meal Replacements. Answer: Supplements promoted as fat
burners have a limited impact on weight loss with most ingredients
lacking quality evidence. However, the use of protein-rich meal
replacements one to two times/day has been shown to improve
weight-loss success, body composition, and maintenance of a
healthy body weight.
◉ Beta Alanine. Answer: For healthy individuals who perform
primarily high-intensity exercise lasting 30 seconds to 10 minutes,
beta alanine supplementation may offer a performance benefit.
Typical use includes a 2- to 4-week loading phase using 4 to 6 grams
daily in divided doses. Skin tingling, a phenomenon known as
paresthesia, is a reported side effect and may be minimized by
taking daily doses in two to three smaller servings throughout the
day and may diminish with continued use.
◉ Sodium Bicarbonate. Answer: Sodium bicarbonate acts as a
buffering agent during high-intensity training between 60 seconds
, and 10 minutes. Typical use includes single doses of 0.2 to 0.4
gram/kilogram body weight taken 1 to 2.5 hours before exercise or
split doses over 3 hours. GI upset is reported with use and may be
alleviated with split doses and/or ingestion with carbohydrate.
◉ Psychology. Answer: The study of the mind and behaviors.
◉ Quantitative Research. Answer: Focuses on variables that can be
directly measured and assessed.
◉ Qualitative Research. Answer: Focuses on people in terms of how
situations and experiences are perceived and how people interact
and utilizes interviews and observations where the results are
grouped together by themes that have emerged.
◉ Empathy. Answer: The ability to identify with another person's
feelings, attitudes, or thoughts.
Enhances the relationship with the client by building trust and
improving communication
◉ Stages of Change Model: Precontemplation. Answer: When an
individual is not thinking of changing and has no intention to
change.
