Essential nutrient?

a) are made by the body
b) only can be supplied adequately with dietary supplements
c) must be obtained through diet
d) consist of over 75 different types of nutrients

Thank you for using the Jiskha Homework Help Forum. Only through diet can they be obtained.

The correct answer is option c) Essential nutrients must be obtained through the diet.

To arrive at this answer, we can eliminate the other options:

a) are made by the body - This is incorrect because essential nutrients are not produced by the body in sufficient amounts, which is why they need to be obtained through diet.

b) only can be supplied adequately with dietary supplements - While some essential nutrients can be obtained through dietary supplements, it is not the only way to acquire them. A well-balanced diet can provide all the necessary essential nutrients.

d) consist of over 75 different types of nutrients - This option is incorrect because essential nutrients do not consist of a fixed number of nutrients. Instead, essential nutrients refer to a group of nutrients, including vitamins, minerals, fatty acids, and amino acids, that are required for the body to function properly.

Therefore, the correct answer is c) must be obtained through the diet, as essential nutrients cannot be produced by the body in sufficient quantities and need to be obtained from the foods we eat.
