D). But it has not been proven to boost the immune system.

Explanation:

As per the question, maintaining a healthy lifestyle through diet and exercise is significant however it has not been proven to boost the immune system. A healthy lifestyle including a balanced diet along with regular exercise corresponds to enhancing immunity and contracts the risk of diseases yet no specific proof has been scientifically approved that a healthy lifestyle(including exercise and healthy diet) nurtures the immune system. Thus, option D is the correct answer.

Final answer:

A healthy diet and regular exercise positively impact the immune system while stress can have negative effects. Temporary stress may not significantly affect a healthy person's immunity, but prolonged stress or conditions like immunosuppression can weaken the immune response.

Explanation:

Eating a healthy diet and exercising regularly does boost your immune system. Research has shown that these lifestyle choices have a positive effect on the immune system, which fights off pathogens and prevents us from falling sick. It is also important to note that being sedentary or having an unhealthy diet can weaken the immune system, making us more susceptible to infections or ailments.

Stress can negatively impact the immune system as well. The human body reacts to stress by releasing cortisol which can suppress the immune system when present in large amounts over a prolonged period. This makes us more susceptible to infections. However, short-term stress may not impair the immune system in healthy individuals to a degree that leads to a higher incidence of diseases.

It is also noted that the immune system can sometimes fail or breakdown, a state referred to as immunosuppression. In such cases, the body becomes more vulnerable to infections and diseases, with the extreme case being HIV/AIDS, where the immune system is completely destroyed by the virus.
