_______ are considered healthy fats that may reduce the risk of heart disease.

  1. a. Saturated fats
  2. b. Trans fats
  3. c. Glycolipids
  4. d. Omega-3 fatty acids

Summary Introduction

Introduction: The fatty acids that contain one or more than one double bonds and makeup fatty acid chains are called as unsaturated fatty acids. Unsaturated fatty acids are essential that help in metabolic functioning in human body. One such essential unsaturated fatty acid is omega-3 fatty acids that our body cannot produce and must be acquired through food. They are considered as healthy fats, as they can reduce the risk of heart-related disease.

Explanation

Reason for the correct answer:

Inflammations in the body can lead to heart attacks due to damages in the blood vessels. Omega-3 fatty acids are the polyunsaturated fatty acid that helps to reduce the inflammation, decreases the blood pressure, reduces irregular heartbeats, lowers triglycerides and thus reduces the risk of heart diseases.

Option d. is given as “Omega-3 fatty acids”. Omega-3 fatty acid reduces lipopolysaccharide-induced inflammation in the blood vessels and thereby reduces the risk of heart diseases.

Hence, the correct answer is option d.

Reasons for the incorrect answers:

Option a. is given as “Saturated fats”.

The fat molecules that are saturated with hydrogen molecules and lack double bond between the carbon molecules are termed as saturated fats. This is incorrect because the saturated fats increase the cholesterol level in body and also increase the risk of heart attack...
