Your Brain on Food

What is the primary component of the brain when dehydrated?

• Proteins

• Carbohydrates

• Lipids

• Micronutrients

• Things I should have said in an argument last year

Answer explanation

The brain is primarily composed of lipids, which are crucial for maintaining its structure and function. When dehydrated, the lipid content becomes more significant as it helps preserve cell integrity and signaling.

Lipids are another word for fats.

Which essential fatty acids are linked to preventing degenerative brain conditions?

• Omega 9

• Omega 3 and 6

• Trans fats

• Saturated fats

How do amino acids influence our feelings and behaviors?

• By increasing blood sugar levels

• By acting as precursors to neurotransmitters

• By providing energy directly to brain cells

• By facilitating the absorption of fats

Which of the following foods is most likely to cause a rapid increase and subsequent drop in blood sugar levels?

• Oats

• Whole grains

• White bread

• Legumes

Answer explanation

White bread is a refined carbohydrate that is quickly digested, leading to a rapid spike in blood sugar levels followed by a sharp drop. In contrast, oats, whole grains, and legumes have a lower glycemic index and provide more stable energy.

What role do antioxidants play in brain health?

• They increase glucose absorption

• They strengthen the brain against free radicals

• They provide essential fatty acids

• They promote the release of neurotransmitters

Answer explanation

Antioxidants play a crucial role in brain health by strengthening the brain against free radicals, which can cause oxidative stress and damage. This protective effect helps maintain cognitive function and overall brain integrity.

What is the percentage of energy resources used by the brain compared to its body weight?

• 5%

• 10%

• 15%

• 20%

Answer explanation

The brain uses about 20% of the body's total energy resources -- despite accounting for only about 2% of body weight. This high energy consumption is due to its complex functions and activity.

Which micronutrients are specifically mentioned as vital for brain health?

• Vitamins A and C

• Vitamins B6, B12, and folic acid

• Vitamins D and E

• Vitamins K and B1

Answer explanation

Vitamins B6, B12, and folic acid are crucial for brain health as they support neurotransmitter function and cognitive processes, making them essential for maintaining mental clarity and overall brain function.

Which minerals are fundamental to brain health and early cognitive development?

• Folate, Niacin, Riboflavin, Thiamine

• Vitamin C, Vitamin D, Vitamin E, Vitamin K

• Iron, Copper, Zinc, Sodium

• Calcium, Magnesium, Potassium, Phosphorus

The brain requires a steady supply of __ to function properly and avoid nutrient deficiency.

Which type of carbohydrates causes a rapid release of glucose into the blood?

• All of the above

• Fiber

• Sugar

• Starch
