Answer:
Being physically active, option B
Step-by-step explanation:
The best way to tackle this question is by process of elimination. Humans cannot avoid all sodium intake because sodium is an essential electrolyte needed for maintaining homeostasis of fluids in the body. Saturated fats, such as those produced by animal-based food products, can increase the risk of developing cardiovascular health issues, which would not pair with a well-balanced diet outside of reasonable moderation. Unless contraindicated by an acute ailment, limiting physical activity would increase the risk of developing preventable chronic diseases, such as (again) cardiovascular health issues.
One's goal should be the opposite of this last point. With a well-balanced diet, increasing physical activity can help translate short-term results into sustainable long-term habits thereby reducing the risk of preventable chronic diseases and conditions.
Thus, option B, being physically active, is the best available answer.
