What type of exercise is recommended in the dietary guidelines for cancer prevention?

Choosing 30 minutes of physical activity per day as the recommended type of exercise in dietary guidelines for cancer prevention is supported by a wide body of research that connects moderate physical activity to reduced cancer risk. Engaging in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity weekly is beneficial for maintaining a healthy weight, improving immune function, and reducing the risk of various cancers.

This amount of physical activity helps to enhance overall health, which is critical for preventing numerous diseases, including cancer, by aiding in weight management, improving cardiovascular health, and enhancing energy metabolism. Moderate activities can include walking, cycling, and swimming, making it accessible for many individuals, especially older adults.

While high-intensity workouts can be advantageous for some, they may not be suitable for everyone, especially older adults or those with certain health conditions. Weight training is certainly important for muscle strength and metabolic health, but it should be part of a broader physical activity plan that includes aerobic exercise. Lastly, the absence of a specific recommendation about physical activity would imply a lack of guidance, which does not align with established public health recommendations for cancer prevention.
