Hereditary hemochromatosis

Elevated ferritin combined with high transferrin saturation is the hallmark presentation of hereditary hemochromatosis, a condition requiring medical management and dietary iron reduction.

Question 2

Which dietary approach has the most evidence for reducing blood pressure in hypertensive adults, beyond sodium restriction alone?

Accepted Answer

DASH (Dietary Approaches to Stop Hypertension) diet

The DASH diet, rich in potassium, magnesium, calcium, and fiber while low in saturated fat and sodium, has robust RCT evidence for clinically significant blood pressure reduction.

A patient with celiac disease continues to have gastrointestinal symptoms despite following a gluten-free diet. What is the most likely nutritional concern to investigate first?

Accepted Answer

Secondary lactose intolerance due to villous atrophy

Villous atrophy from celiac disease reduces lactase production; secondary lactose intolerance is common in celiac patients and persists until the gut heals.

Which lipoprotein is considered the primary carrier of cholesterol from the liver to peripheral tissues?

Low-density lipoprotein (LDL)

LDL is the end product of VLDL catabolism and is the primary carrier delivering cholesterol to peripheral cells via the LDL receptor pathway.

Question 5

A post-bariatric surgery patient (Roux-en-Y gastric bypass) is at highest risk for deficiency of which nutrient due to bypass of the duodenum?
