5 reasons to eat more fibre

What you eat can play a big role in how you feel during and after menopause, and fibre is a really important (crunchy, chewy) piece of that.

Last updated 29 August 2025

With nicknames like “roughage” and “bulk,” fibre might not sound exciting — but don’t underestimate its power, especially if you’re navigating menopause. “Few terms in the nutrition world sound less sexy,” says registered dietitian Lauren Slayton, M.S., R.D., “but the benefits of fibre are about as valuable as you can get.”

What is fibre, anyway?

Fibre is a type of carbohydrate, but unlike sugars and starches, your body can’t digest it. Instead, it moves through your digestive system, helping with everything from blood sugar regulation to gut health. Fibre comes in two types:

  • Soluble fibre, found in oats, beans, and lentils, dissolves in water and slows digestion.

  • Insoluble fibre, found in wholegrains, nuts, and many veggies, helps food pass more quickly through the stomach and intestines while adding bulk to stool.

Fibre is only found in plant foods — think fruits, vegetables, legumes, and whole grains — not in meat, dairy, or eggs.

Why fibre matters more during menopause

As estrogen declines, women become more vulnerable to health issues such as heart disease, weight gain, insulin resistance, and digestive changes. Here's where fibre can help:

1. Supports heart health

Heart disease becomes a greater risk after menopause. Fibre — especially soluble fibre — can help lower LDL (“bad”) cholesterol by binding with it and flushing it out of the body. It also may reduce blood pressure, further supporting cardiovascular health.

2. Improves blood sugar and insulin sensitivity

Postmenopausal women are more prone to insulin resistance, which can lead to type 2 diabetes. Fibre helps by slowing down glucose absorption and improving how the body responds to insulin. Meeting fibre goals consistently can lower your risk of developing diabetes by 20 to 30 percent, according to research in The Journal of Nutrition.

3. Eases digestion

Many women experience constipation during and after menopause. Fibre’s well-known digestive benefits — bulking up and softening stools, promoting regularity — are especially helpful here. Plus, certain fibres feed gut-friendly bacteria, which are linked to better overall gut health and possibly better immunity.

4. Helps maintain weight

Midlife weight gain is common, but fibre can help keep it in check. It promotes satiety, meaning you feel full longer, which may reduce overeating. Studies show that people who consume more fibre tend to gain less weight and have smaller increases in waist circumference over time.

5. May reduce cancer risk

Some studies suggest that higher fibre intake may lower the risk of breast and colorectal cancers. Fibre helps promote healthy cell turnover in the colon and may influence hormone metabolism in ways that protect breast tissue.

What about supplements?

Fibre supplements can help fill in nutritional gaps, but they don’t offer the full package of benefits that whole foods do. Whole foods provide additional nutrients like antioxidants, vitamins, and water content that support overall health.
