Nutrition and Diet Therapy Practice Test

Nutrition plays a significant role in mental health, primarily through the impact of certain nutrients on brain biochemistry. The brain requires a variety of vitamins, minerals, fatty acids, and amino acids to function optimally. For instance, nutrients like omega-3 fatty acids, B vitamins, and antioxidants are crucial for processes such as neurotransmitter synthesis, neuroplasticity, and reducing inflammation.

Research has shown that deficiencies in key nutrients can lead to mood disorders, cognitive decline, and other mental health issues. For example, omega-3 fatty acids are linked to improved mood and lower rates of depression, while B vitamins can influence energy metabolism and cognitive function.

In contrast, the other options do not fully capture the complex relationship between nutrition and mental health. Merely stating that nutrition provides essential vitamins oversimplifies the issue, as it excludes the broader context of how different nutrients interact and support brain health. The assertion that nutrition has no impact on mental health is inconsistent with a wealth of scientific evidence demonstrating clear connections. Lastly, while calories provide the energy needed for bodily processes, they do not exclusively influence mental health; rather, the quality of the diet and the types of nutrients consumed are pivotal in this regard.
