What is the impact of an unhealthy diet on health?

• A. It can lead to increased weight and hormonal imbalance, contributing to cancer
• B. It improves metabolic health
• C. It has no impact on cancer risk
• D. It reduces weight

Answer: (A)

Unhealthy diets often lead to excess weight and hormonal changes that together create a body environment more conducive to disease. When people gain weight, especially excess fat, it isn’t just about how it looks; fat tissue changes hormonal signals—insulin resistance and higher insulin levels, along with shifts in estrogen and inflammatory molecules. This hormonal and inflammatory milieu can promote the development and progression of cancer, among other health problems. So the statement that an unhealthy diet can lead to increased weight and hormonal imbalance, contributing to cancer, best reflects how diet quality impacts health.

The other ideas don’t fit because an unhealthy diet does not improve metabolic health, there is evidence linking diet to cancer risk rather than none, and it does not reduce weight.
