Why are industrial trans fats considered particularly harmful?

Last Updated:

This question tests a core concept of human nutrition: Industrial trans fats worsen the blood-lipid profile by raising LDL cholesterol and often lowering protective HDL cholesterol. Understanding this relationship helps explain how the body obtains energy, builds tissues, maintains immunity and prevents deficiency disease. The correct answer is They raise LDL and can lower HDL cholesterol. Students should connect the nutrient with its principal function, common dietary sources and characteristic deficiency or excess.

AThey raise LDL and can lower HDL cholesterol
BThey provide no energy
CThey are a type of vitamin
DThey prevent all inflammation
Correct Answer: They raise LDL and can lower HDL cholesterolYour Answer: A

Explanation

Correct answer: They raise LDL and can lower HDL cholesterol. Industrial trans fats worsen the blood-lipid profile by raising LDL cholesterol and often lowering protective HDL cholesterol. They are associated with increased cardiovascular risk, which is why many health authorities recommend eliminating partially hydrogenated oils. Trans fats still provide energy, are not vitamins and do not prevent inflammation; they may promote adverse inflammatory effects. The distractors are related to nutrition, but each describes a different nutrient, function, energy value or deficiency condition. A good solution identifies the key physiological clue and then checks every option against established nutritional science.

Nutrition FAQs

Common questions and clear answers for this topic.

What are the major nutrients required by the human body?

The human body requires six major nutrients: carbohydrates (energy source), proteins (growth and repair), fats (energy storage and insulation), vitamins (regulatory functions), minerals (bone and metabolic functions), and water. Each nutrient plays a specific role in maintaining health. A balanced diet includes all these nutrients in proper proportions.

What are vitamins and what is their role in the body?

Vitamins are organic compounds required in small quantities for normal body function. They are classified as fat-soluble (A, D, E, K) and water-soluble (B-complex, C). Vitamin A maintains vision, D helps calcium absorption, C builds immunity and prevents scurvy, B1 (thiamine) prevents beriberi, and B12 is essential for nerve function and blood formation.

What are deficiency diseases caused by lack of nutrients?

Nutrient deficiency diseases include: Scurvy (Vitamin C deficiency), Rickets (Vitamin D deficiency in children), Beriberi (Vitamin B1/thiamine), Night blindness (Vitamin A), Anaemia (Iron or B12 deficiency), Goitre (Iodine deficiency), Kwashiorkor and Marasmus (protein-energy malnutrition), and Pellagra (Niacin/Vitamin B3 deficiency).

What is the difference between carbohydrates, proteins and fats?

Carbohydrates provide immediate energy (4 kcal/g) and are found in rice, wheat, and fruits. Proteins are building blocks made of amino acids (4 kcal/g), essential for growth and repair, found in eggs, meat, legumes. Fats store energy (9 kcal/g), insulate organs, and aid vitamin absorption; found in oils, butter, nuts.

What is a balanced diet and why is it important?

A balanced diet contains all essential nutrients — carbohydrates, proteins, fats, vitamins, minerals, and water — in the right proportions. It supports growth, maintains energy, boosts immunity, and prevents deficiency diseases. ICMR recommends a daily intake that includes cereals, pulses, vegetables, fruits, dairy, and adequate water.
