DHA Nutritionist - Exam Topics Sample Questions

Some nutritional deficiencies are challenging and are not simply caused by poor diet.  All of the following are examples of this except:

Correct Answer:
bodybuilders who take supplements and eat regularly to maintain muscle


some nutritional deficiencies arise from complex causes beyond just inadequate dietary intake. factors such as biological changes, environmental conditions, and lifestyle choices can also play significant roles. for instance, certain groups of people are more prone to specific deficiencies due to unique physiological or environmental circumstances.

pre-menopausal women, for example, might suffer from iron deficiency not solely because of a poor diet but also due to the loss of blood during menstruation, which increases iron requirements. similarly, older individuals may lack vitamin b12 because the ability to absorb this vitamin decreases with age, often irrespective of their dietary intake. people living in northern climates or who predominantly work indoors could be deficient in vitamin d due to limited exposure to sunlight, which is necessary for the body to synthesize this vitamin.

however, the situation is different for bodybuilders who take supplements and maintain a regular eating schedule specifically designed to support muscle growth and maintenance. this group actively manages their nutrient intake to meet their bodily demands, and their supplementation is typically aimed at providing an excess of required nutrients rather than compensating for a deficiency. in this case, any nutritional deficiencies that might occur would more likely be due to imbalances or excessive intake rather than the kind of involuntary deficiencies seen in other mentioned groups.

therefore, among the examples provided, bodybuilders who take supplements and eat regularly to maintain muscle mass do not fit the category of having nutritional deficiencies that are not caused by a poor diet. their proactive regimen of supplement intake and planned diet generally ensures they meet or exceed their nutritional needs, contrasting with the involuntary deficiencies experienced by the other groups mentioned.

All of the following are common allergens except:

Correct Answer:
carriers


all of the following are common allergens except "carriers." this question asks to identify which among the listed items is not typically considered an allergen. allergens are substances that can cause allergic reactions in some people.

certain foods are well-known allergens. foods such as peanuts, shellfish, eggs, and milk are common causes of food allergies. a food allergy occurs when the immune system mistakenly identifies a harmless food protein as a threat and launches an immune response. this response can involve the production of antibodies, leading to symptoms that range from mild (rashes, hives, itching) to severe (anaphylaxis).

pollen, dust, and animal dander are also major allergens. these substances can trigger allergic reactions primarily affecting the respiratory system, such as allergic rhinitis and asthma. pollen from plants, dust mite waste, and flakes of skin or fur from animals are common triggers that can cause sneezing, coughing, and itchy eyes.

drugs and cosmetics can contain allergenic substances as well. some people may experience allergic reactions to certain ingredients in medications or beauty products. these reactions can manifest as skin irritation, rashes, or more severe responses, depending on the individual's sensitivity.

the term "carriers" in this context does not fit the typical definition of an allergen. while "carriers" could refer to substances or organisms that transport or harbor allergens, they themselves are not allergens. in the context of allergies, carriers might be involved in the delivery or presence of allergens but do not independently elicit an allergic response. therefore, "carriers" is the correct answer as it is not a common allergen itself.
