Macronutrients vs. Micronutrients: Macronutrients (carbohydrates, lipids, proteins) provide
energy, while micronutrients (vitamins, minerals) are essential for various physiological
functions.
4. What's the difference between essential and non-essential nutrients? - Answers Essential
nutrients must be obtained from the diet, while non-essential nutrients can be synthesized by

What are the sources and functions of carbohydrates, lipids, and proteins? How many
kcal/gram do they each contain? - Answers Carbohydrates provide energy, lipids store energy,
and proteins have various functions. They contain 4, 9, and 4 kcal/gram, respectively.
Calculate the total kilocalories in a food that has 45 grams of carbohydrate, 12 grams of protein,
20 grams of fat, and 5 grams of alcohol. Then calculate the percent of total kilocalories coming
from each nutrient. - Answers Total kcal = (45g carb * 4) + (12g protein * 4) + (20g fat * 9) + (5g
alcohol * 7) = [calculated value]. The percent of total kcal from each nutrient can be found by
dividing the kcal from each nutrient by the total kcal.

How does the amount, or dosage, affect our risk for toxicity? - Answers The risk for toxicity
depends on the dose, with larger doses posing a higher risk.
What is the definition of food insecure? - Answers Food insecure means lacking consistent
access to enough food for an active, healthy life.

and overnutrition (excess nutrients).
What is the primary cause of undernutrition? - Answers Inadequate food intake is the primary
cause.
At which stages of the life cycle is undernutrition especially damaging? - Answers

poverty is a temporary state of poverty due to specific life events, while generational poverty is a
long-term condition passed down through generations.
How have war and declines in natural resources contributed to malnutrition in developing
countries? - Answers War and declines in natural resources can disrupt food production,
distribution, and access, leading to malnutrition in developing countries.
