Question 1

Which nutrient found in plants inhibits iron and zinc absorption and must be considered in plant-based diets?

Accepted Answer

Phytates (phytic acid)

Answer

Phytates (phytic acid) in grains, legumes, and seeds bind to minerals like iron and zinc, reducing their absorption in the gut.

Question 2

Which calcium-rich plant-based food is also fortified in many plant milks?

Accepted Answer

Soy milk and fortified plant milks

Answer

Fortified soy milk and other plant milks are excellent calcium sources for plant-based eaters, often providing similar calcium levels to cow's milk.

Question 3

What is the concept of 'protein complementarity' in plant-based nutrition?

Accepted Answer

Combining different plant proteins to ensure all essential amino acids are obtained

Answer

Protein complementarity involves combining plant protein sources (like rice and beans) to provide all essential amino acids, though this doesn't need to happen at every single meal.

Question 4

Which vitamin is particularly important to supplement on a plant-based diet due to limited sun exposure and lack of dietary sources?

Accepted Answer

Vitamin D

Answer

Vitamin D is limited in plant foods and many people, especially those indoors, are deficient; supplementation or fortified foods are important on a plant-based diet.

Question 5

What does DHA and EPA (long-chain omega-3s) conversion from plant-based ALA involve?

Accepted Answer

Inefficient conversion; algae-based supplements are often recommended

Answer

The body converts ALA to DHA and EPA very inefficiently; algae-based omega-3 supplements are often recommended for plant-based eaters as a direct source.
