Our brain mainly depends on which of the following food?

 The correct answer is Only glucose.

Key Points

• ​Glucose is the primary energy source for the brain, which needs it to function.
• This common simple sugar is transported throughout the body via the bloodstream where it is then used as fuel by tissue cells.
• Vitamin C promotes general brain health and aids in preventing damage to brain cells. In fact, a study revealed that vitamin C may help stave off Alzheimer's.
• The chemical formula for glucose is C6H12O6. It is the main free sugar present in higher animals' blood and can be found in fruits and honey. It is the source of energy for cellular activity, hence controlling its metabolism is crucial. ​

Additional Information

• ​​You obtain fats as a type of nutrition from your food. While eating certain fats is necessary, eating too much can be unhealthy.
• Since it was shown that the amino acids from consumed protein could be turned into glucose, there has been interest in how proteins or amino acids affect glucose metabolism for at least a century.
• After being broken down into fatty acids, fats are used as a source of energy. Although protein can be used for energy, its primary function is in the synthesis of hormones, muscle, and other proteins. Cells use glucose, which is broken down, as an energy source. The liver stores surplus.
