Which diet has been shown to have substantially lower rates of cardiovascular disease and may also reduce risk for cognitive decline?
Diabetic diet
Mediterranean diet
Keto diet
Vegetarian diet
The Correct Answer is B
A. A diabetic diet focuses on controlling blood glucose and carbohydrate intake to manage diabetes. While it supports metabolic health, it has not been specifically shown to reduce rates of cardiovascular disease or cognitive decline to the extent seen with the Mediterranean diet.
B. The Mediterranean diet emphasizes fruits, vegetables, whole grains, legumes, nuts, olive oil, and fish, with moderate consumption of dairy and minimal red meat. This diet is rich in antioxidants, monounsaturated fats, and omega-3 fatty acids, which contribute to improved heart health by reducing inflammation, lowering LDL cholesterol, and supporting endothelial function. Numerous studies also suggest the Mediterranean diet may reduce the risk of cognitive decline and neurodegenerative diseases like Alzheimer’s, likely due to its anti-inflammatory and neuroprotective nutrient profile.
C. The ketogenic (keto) diet is high in fat and very low in carbohydrates, which can help with weight loss and blood sugar control. However, its long-term effects on cardiovascular health are still debated, and it has not been conclusively shown to reduce cognitive decline. Some studies even suggest potential risks due to high saturated fat intake.
D. A vegetarian diet excludes meat and sometimes other animal products, which can reduce saturated fat intake and support heart health. However, while vegetarian diets can improve cardiovascular risk factors, they do not consistently demonstrate the same broad, evidence-backed reductions in cardiovascular disease and cognitive decline as the Mediterranean diet, which includes a balanced mix of plant and healthy animal foods.

Correct Answer is D
Explanation
A. Disaccharides are carbohydrates composed of two sugar molecules linked together, such as sucrose (table sugar), lactose, and maltose. They are simpler than polysaccharides and provide quick energy but are not considered complex carbohydrates.
B. Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar molecule such as glucose, fructose, or galactose. They are the building blocks of more complex carbohydrates but are not complex carbohydrates themselves.
C. Glycogen is a specific type of polysaccharide that serves as the body’s storage form of glucose in liver and muscle tissues. While glycogen is a complex carbohydrate, the term in the question refers to complex carbohydrates in general, not just the stored form.
D. Polysaccharides are complex carbohydrates composed of long chains of glucose units linked together. Examples include starch (found in plants), glycogen (stored in animals), and cellulose (a structural component in plants). Polysaccharides provide sustained energy as they are broken down more slowly than simple sugars and play roles in energy storage and structural support.
Correct Answer is D
Explanation
A. While eating a variety of colorful fruits and vegetables can indicate a range of nutrients, color alone does not guarantee a healthful diet. A diet can be colorful but still high in added sugars, unhealthy fats, or processed foods.
B. Whether foods are organic or not does not determine the overall healthfulness of the diet. Both organic and conventionally grown foods can contribute to a balanced, nutritious diet. Excluding organic foods is not a key component of healthful eating.
C. Featuring whole foods—minimally processed foods like fruits, vegetables, whole grains, legumes, and lean proteins—is beneficial, but this alone does not fully define a healthful diet. Other factors, such as nutrient density and balance, are also critical.
D. Nutrient-dense foods provide a high amount of essential nutrients (vitamins, minerals, protein, fiber) relative to their calorie content. Choosing nutrient-dense foods helps ensure adequate nutrition while supporting healthy body weight and reducing the risk of chronic diseases. Examples include leafy greens, berries, lean proteins, whole grains, and legumes. Focusing on nutrient-dense foods is a cornerstone of a healthful diet.
