Which dietary component primarily aids in lowering LDL cholesterol by forming a gel in the digestive tract?

Answer

Soluble fiber, found in foods like oats and beans, dissolves in water to form a viscous gel in the digestive tract. This gel binds to cholesterol and bile acids, preventing their reabsorption and promoting their excretion, which effectively lowers circulating LDL ('bad') cholesterol levels. Insoluble fiber primarily adds bulk and promotes intestinal motility.

Bleeding gums and poor wound healing are classic symptoms of a deficiency in which vitamin?

Answer

Bleeding gums, easy bruising, and impaired wound healing are the hallmark symptoms of scurvy, a disease caused by a severe deficiency of Vitamin C (ascorbic acid). Vitamin C is necessary for the synthesis of collagen, a protein vital for the health of connective tissues, blood vessels, and gums.

Which vitamin class must be consumed regularly due to limited body storage and easy excretion?

Answer

Water-soluble vitamins (e.g., Vitamin C and B-complex) dissolve in water and are not stored in significant amounts by the body, leading to their rapid excretion via urine. Consequently, they must be consumed regularly. Fat-soluble vitamins (A, D, E, K) are absorbed and stored in the body's fatty tissues and liver, meaning they do not require daily intake.

Which nutrient’s intake does WHO recommend should be less than 1% of total energy intake to prevent noncommunicable diseases?

Answer

The World Health Organization (WHO) recommends that the intake of trans-fats should be less than 1% of total energy intake as part of a healthy diet to prevent noncommunicable diseases (NCDs). The recommendation for saturated fats is less than 10% of total energy intake, and for free sugars, it is less than 10% (with a further reduction to less than 5% suggested for additional health benefits). Dietary fiber, conversely, is recommended to be increased.

Regular consumption of foods high in partially hydrogenated oils primarily increases the risk of which chronic condition?

Answer

Trans fatty acids, commonly found in partially hydrogenated oils, are known to raise Low-Density Lipoprotein (LDL or 'bad') cholesterol levels and lower High-Density Lipoprotein (HDL or 'good') cholesterol levels. This change significantly increases the risk of atherosclerosis, which leads to Coronary Artery Disease (CAD). The elimination of industrially produced trans fats is a major global public health goal to reduce cardiovascular mortality.

The recommendation for diets rich in low-glycemic index foods is primarily based on their effect on what?

Answer

Foods with a low Glycemic Index (GI) are digested and absorbed more slowly. This results in a gradual, sustained release of glucose into the bloodstream, rather than a rapid spike. This slower absorption is crucial for better blood sugar control, improved insulin sensitivity, and reduced risk of Type 2 Diabetes, which forms the primary basis for their recommendation in metabolic health.

Which essential macronutrient’s primary function is to serve as the building block for structural tissue and enzymatic reactions?

Answer

Proteins are composed of amino acids, often called the 'building blocks of life,' and their primary roles include the growth, repair, and maintenance of body tissues (like muscles and organs) and forming enzymes and hormones. Carbohydrates and Fats are primarily energy sources.

What is the primary function of soluble dietary fiber in the human body?

Answer

Soluble dietary fiber forms a gel in the digestive system, which slows down the digestion and absorption of nutrients. This process is key to reducing the absorption rate of glucose (helping regulate blood sugar) and binding to cholesterol in the gut (lowering blood cholesterol).

Which fat-soluble vitamin is crucial for the liver to synthesize the proteins necessary for normal blood coagulation (clotting)?

Answer

Vitamin K is essential for activating clotting factors, such as prothrombin, which are produced in the liver. A deficiency can lead to excessive bleeding.
