Question

Identify the diseases in which following diets are prescribed:
(a) High fibre diet
(b) Iron rich diet

Hint:

To maximize iron absorption: pair iron-rich foods (like spinach or beans) with foods high in Vitamin C (such as lemons or oranges). Vitamin C helps convert non-heme iron into a form that is much easier for the body to absorb.

Answer 1

Step 1: Analyzing the High-Fiber Diet (a):
Dietary fiber consists of non-digestible plant carbohydrates (soluble and insoluble) that add bulk to stool and absorb water in the digestive tract. A high-fiber diet is primarily prescribed to manage:

• Constipation: Fiber increases fecal bulk and accelerates peristalsis, promoting regular bowel movements.
• Diabetes Mellitus: Soluble fiber forms a gel-like substance in the gut that slows the digestion and absorption of glucose, preventing sudden blood sugar spikes after meals.
• Hypercholesterolemia (Cardiovascular Disease): Soluble fiber binds to bile acids in the gut, promoting their excretion and helping lower circulating LDL cholesterol levels.

Step 2: Analyzing the Iron-Rich Diet (b):
Iron is an essential micronutrient required to synthesize hemoglobin, the protein in red blood cells that carries oxygen throughout the body. An iron-rich diet is primarily prescribed to treat:

• Iron-Deficiency Anemia: The most common nutritional deficiency worldwide, characterized by low hemoglobin levels, fatigue, weakness, and pale skin.
