Questions and Answers

Why did humans survive periods of sporadic or seasonal hunger as hunter-gatherers?

They had access to highly palatable beverages with added sugar which sustained them during periods of hunger.
Drinking water does not interfere with episodic food intake, allowing for gorging when food was available. (correct)
Modern technology provided a consistent food supply, negating the impact of sporadic hunger.
They primarily consumed 100% fruit juice, which provided essential nutrients during scarce times.

What is a key reason consumption of beverages with added sugar or 100% fruit juice contributes to weight gain and increased risk of NR-NCDs?

The caloric content of these beverages is negligible compared to solid foods.
These beverages promote satiety, leading to reduced consumption of solid foods.
These beverages often replace water intake without causing a corresponding reduction in solid food consumption. (correct)
These beverages contain essential nutrients that counteract the negative effects of solid foods.

Why might a BMI of 25 kg/m² be a significant cut-off for assessing NCD risk in LMICs?

Extensive research has shown that NCD risks are elevated at this BMI level in these populations. (correct)
Healthcare systems in LMICs are better equipped to manage NCDs at this BMI level.
Genetic factors in LMICs protect against NCDs until BMI exceeds this threshold.
Individuals in LMICs generally have lower muscle mass, making BMI less accurate.

For which populations might a lower BMI threshold (e.g., 23-25 kg/m²) be more appropriate when assessing risks of hypertension, diabetes, and other NCDs?
