Beginner’s Guide to Fiber: How to Boost Bone Health, Gut Health & Energy

Fiber doesn’t get the spotlight it deserves. But if you’re a woman over 40 trying to feel better in your body, support your bones, and age with strength and ease, it might be the missing link. This post will walk you through what fiber is, why it matters – especially for your bone health & staying active – and how to add more of it to your plate—the simple, sustainable way.

What Is Fiber?

Fiber is a type of carbohydrate your body can’t digest. It passes through your digestive system intact, doing all sorts of wonderful things along the way. There are two main types:

• Soluble: dissolves in water and forms a gel-like consistency in your gut. It slows digestion, stabilizes blood sugar, and helps manage cholesterol levels. (Think oats, apples, beans.)
• Insoluble: doesn’t dissolve and adds bulk to your stool, helping keep digestion regular. (Think leafy greens, nuts, whole grains.)

Most whole plant foods contain a mix of both.

Why We Need a High-Fiber Diet (Especially After 40)

For women in midlife and beyond, fiber plays a crucial role in:

• Bone health: A healthy gut helps your body absorb calcium, magnesium, and other nutrients critical for strong bones.
• Hormone balance: Helps remove excess estrogen and supports liver detox pathways.
• Blood sugar control: Prevents sugar spikes and crashes, which is key for mood, metabolism, and energy.
• Digestive health: Keeps things moving and supports regular elimination.
• Weight management: Helps you feel full longer, naturally curbing overeating.
• Lowering inflammation: Chronic inflammation is a driver of aging; fiber helps keep it in check.

Top Foods for a High-Fiber Diet

Here are some of the best fiber-rich foods to keep on hand:

• Raspberries – 8g per cup
• Avocados – 10g per avocado
• Chia seeds – 10g per 2 tablespoons
• Lentils – 15g per cooked cup
• Brussels sprouts – 4g per cup
• Oats – 4g per half-cup dry
• Pears (with skin) – 6g each
• Sweet potatoes (with skin) – 4g each
• Flaxseeds – 3g per tablespoon

Pro Tip: Blend chia or flax into smoothies, top your oats with raspberries, and swap pasta for lentils or sweet potatoes now and then.

How to Follow a High-Fiber Diet

Start small and give your body time to adjust. A sudden jump can cause gas or bloating if your gut isn’t ready.

1. Start slow: Add 5g more fiber per day until you reach 25–30g
2. Drink water: Fiber needs water to do its job
3. Snack smart: Keep fruit, veggies, or trail mix handy
4. Choose whole over refined: Go for brown rice, quinoa, whole fruits
5. Plan with purpose: Factor 75 and Home Chef offer pre-made meals with plant-based sides to make it easy
