National Heart Health Month: The Power of Fiber for a Stronger Heart

Heart health is always important, but February gives us a special reminder to take care of our hearts. Last year, we covered the key nutrients to focus on and avoid for heart health. This year, I want to take things a step further and get into the practical side of things. I’ll be sharing a sample meal plan to help you incorporate heart-healthy choices into your daily routine. Plus, we’ll dive deeper into my #1 favorite nutrient for heart health—fiber!

What Is Fiber?

Fiber is the part of plant-based foods that your body can’t digest. While it passes through your digestive system largely intact, it plays a crucial role in regulating digestion, controlling blood sugar levels, and maintaining healthy cholesterol. There are two main types of fiber: soluble and insoluble. Both types are important for overall health, but today, we’ll focus on soluble fiber, as it has some special benefits for heart health.

Soluble vs. Insoluble Fiber

Soluble Fiber: This type dissolves in water and forms a gel-like substance. It helps lower LDL (the "bad" cholesterol) by about 5-10% because it binds to cholesterol molecules and removes them from your system. Foods rich in soluble fiber include oats, beans, lentils, pears, apples, and citrus fruits.

Insoluble Fiber: This fiber doesn’t dissolve in water. It adds bulk to your stool and helps food pass more quickly through your stomach and intestines. While it doesn’t have a direct effect on cholesterol, it’s still important for digestive health, particularly constipation. Whole grains, cruciferous vegetables, and nuts are great sources of insoluble fiber.

Recommended Fiber Intake

To reap the heart-healthy benefits of fiber, it's recommended that women consume about 25 grams of fiber per day and men about 38 grams. The average American typically consumes only 16 grams per day, so it looks like there's work to do! Let’s dive into how to make that possible!
