What are the benefits of fiber?

Improves digestive health

Fiber supports healthy digestion by adding bulk to stools and promoting regular bowel movements. It helps prevent constipation, and one study’s results found that “a high fiber intake may reduce the risk of diverticular disease, and individuals consuming 30 grams of fiber per day have a 41% reduction in risk compared to persons with a low fiber intake.” A high-fiber diet can also foster a healthy gut microbiome by feeding beneficial bacteria.

Supports heart health

If you’re someone who is concerned about their cholesterol levels, you will be happy to know that soluble fiber helps lower cholesterol levels by binding to cholesterol in the digestive system and removing it from the body. This reduces the risk of heart disease and improves overall cardiovascular health. Additionally, fiber-rich foods help regulate blood pressure and improve circulation.

Aids in weight management

Are you currently losing weight or focused on maintaining a healthy weight? High-fiber foods should be a priority in your diet, as they are filling and take longer to digest, which can reduce overall calorie intake by curbing hunger. They also stabilize blood sugar levels, preventing energy crashes and overeating.

Supports muscle growth and repair

Protein is essential for building and repairing tissues, making it vital for muscle growth and recovery after exercise. It provides the amino acids needed to repair muscle fibers damaged during workouts and helps build lean muscle mass.

Promotes satiety and aids in weight management

Similar to fiber, eating protein-rich foods helps you feel full longer, reducing overall calorie intake. This increased satiety can curb cravings and make it easier to manage weight. High-protein diets are often linked to better appetite control and fat loss while preserving muscle.

Boosts metabolic health

Protein has a higher thermic effect compared to carbohydrates and fats, meaning your body burns more calories in order to digest it. Additionally, consuming adequate protein supports metabolic functions like enzyme production, hormone regulation, and maintaining a healthy immune system.

How much protein and fiber do men need?

Men need about 56 grams of protein daily, according to the Dietary Guidelines for Americans, though active individuals or those looking to build muscle may require more. Protein needs vary based on factors like age, weight, and activity level, typically ranging from 0.8 to 1.6 grams per kilogram of body weight.

For fiber, men should aim for 30 to 38 grams per day, depending on their age. As mentioned before, fiber supports digestion, heart health, and blood sugar regulation.
