Consuming fiber regularly is associated with a lower risk of heart diseases due to several mechanisms. Fiber plays a crucial role in managing cholesterol levels by binding to bile acids in the digestive system, which helps reduce the amount of low-density lipoprotein (LDL), often referred to as "bad" cholesterol. This process can lead to improved heart health over time, as lower cholesterol levels are linked to a reduced likelihood of developing cardiovascular conditions.

In addition to its cholesterol-lowering effect, fiber also contributes to heart health by supporting healthy blood sugar levels and promoting better blood pressure control. Foods high in fiber, such as fruits, vegetables, whole grains, and legumes, are typically nutrient-rich and low in saturated fat, further benefiting cardiovascular health.

The other options, such as increased muscle mass, higher energy levels, and immediate weight gain, do not directly correlate with regular fiber consumption. Muscle mass is primarily influenced by protein intake and physical activity, while energy levels are more connected to overall diet quality and carbohydrate intake, rather than fiber specifically. Immediate weight gain is not a benefit of fiber; instead, fiber can contribute to satiety and weight management over time by reducing hunger and aiding in digestion.
