The Benefits of Fibre in Midlife: Why It Matters for Your Gut, Hormones, Heart and Energy

When most people think about the benefits of fibre during midlife, they often think about digestion or "keeping regular". Whilst fibre is important for digestive health, it does so much more than that.

As hormones shift through midlife, many women notice that their body responds differently to food.

You may notice:

·       Feeling hungry more quickly

·       Craving sweet foods more often

·       Feeling tired all the time

·       Weight gain around the middle

·       Slower digestion or constipation

·       Rising cholesterol levels

·       Hormonal changes becoming a bit more noticeable

·       More aches and pains or taking longer to recover after exercise

This is where fibre comes in. It plays an important role in digestive health, blood sugar balance, appetite regulation, heart health and healthy hormone metabolism. Through its effects on the gut microbiome, fibre also supports the immune system, healthy inflammation and long-term health.

Despite playing such an important role in our health, most adults in the UK still eat far less fibre than is recommended.

In this blog, I'll explain:

• Why fibre is one of the most important nutrients for your health during midlife.

• How it supports your digestion, gut microbiome, blood sugar, heart and hormones.

• Why eating a greater variety of plant foods matters.

• Simple, realistic ways to eat more fibre without overcomplicating your diet.

What Is Fibre?

Fibre is the part of plant foods that our bodies can't fully digest.

Unlike other carbohydrates, which are broken down and absorbed for energy, fibre passes through the digestive system largely intact. As it travels through the gut, it performs a number of important jobs that help support our health.

Fibre is found in a wide range of plant foods, including vegetables, fruit, beans, lentils, wholegrains, nuts, seeds, herbs and spices.

Eating a wide variety of these foods is one of the simplest ways to increase your fibre intake and support your health.

How Much Fibre Do We Need in Midlife?

In the UK, the recommendation for adults is around 30g of fibre per day.

But most people are eating much less than this, the average adult eating less than 20g per day, meaning most of us are missing out on many of the benefits fibre has to offer.

If you don't think you're anywhere near 30g at the moment, don't worry. Most adults in the UK aren't (the latest National Diet and Nutrition Survey 2019-2023 says less than 4% of adults do). Rather than focusing on the numbers, simply look for opportunities to include a few more fibre-rich plant foods in your meals and snacks.

How Fibre Supports Your Digestive Health

When most people think about fibre, digestive health is usually the first thing that comes to mind and for good reason. One of fibre's best-known roles is helping to keep the digestive system working well.

Getting enough fibre helps support regular bowel movements and can reduce the likelihood of constipation. It also helps keep stools soft and well formed, which may benefit some people who experience loose stools or diarrhoea.

It’s really common to notice changes in digestion during midlife. Hormonal changes, reduced physical activity, stress, travel and certain medications can all contribute to a slower digestive system or changes in bowel habits.

Although increasing your fibre intake won't solve every digestive problem, it is one of the simplest and most effective ways to support digestive health.

If you've been eating a fairly low-fibre diet, it's important to increase your intake gradually. Suddenly adding large amounts of beans, lentils, vegetables and seeds can leave you feeling bloated or uncomfortable while your digestive system adjusts.

Instead, increase fibre little by little, drink plenty of water and give your gut time to adapt. Most people find that any temporary increase in bloating settles as their digestive system becomes accustomed to the extra fibre.

If you're struggling with ongoing digestive symptoms such as persistent constipation, diarrhoea, bloating or abdominal pain, it's important to speak to a healthcare professional, as these symptoms can sometimes have an underlying cause that needs investigating.

How Fibre Supports A Healthy Gut Microbiome

Supporting regular bowel movements is only part of the story. One of the reasons fibre has such wide-ranging effects on our health is because of what happens when it reaches the large intestine.

Our gut is home to trillions of bacteria and other microorganisms, collectively known as the gut microbiome. Many of these play important roles in keeping us healthy, and one of the best ways to look after them is by eating enough fibre.

When the beneficial bacteria in our gut feed on fibre, they produce substances called short-chain fatty acids (SCFAs). These help nourish the cells lining the gut, strengthen the gut barrier and influence many aspects of our health, including our immune system, healthy inflammation, hormone health and even mood.

This is one of the reasons I encourage people to eat a wide variety of plant foods. The greater the variety of plants we eat, the greater the variety of beneficial bacteria we can support, helping to build a healthier, more diverse gut microbiome.

Plant variety doesn't have to be complicated. Vegetables, fruit, beans, lentils, wholegrains, nuts, seeds, herbs and spices all count. Simply including a greater variety of these foods over the course of a week is a positive step towards supporting your gut microbiome and, in turn, many other aspects of your health.

How Fibre Supports Blood Sugar, Appetite and Energy

 If you often find yourself feeling hungry an hour or two after eating, reaching for something sweet in the afternoon or struggling with energy dips, your meals may not be keeping you satisfied for as long as they could. Fibre can help.

One of fibre's most important jobs is helping to slow the release of glucose (sugar) into the bloodstream after eating.

Meals that are low in fibre are often digested more quickly, which can lead to a rapid rise in blood sugar followed by a fall not long afterwards. For many people, this can leave them feeling tired, hungry and craving sugary foods as their body looks for another quick source of energy.

Including fibre-rich foods as part of your meals helps slow this process, supporting steadier blood sugar levels and more consistent energy throughout the day.

Fibre also helps you feel fuller for longer. Fibre-rich foods generally take longer to chew and digest, helping to slow the emptying of the stomach and increase feelings of fullness after a meal.

Together, these effects can help you stay satisfied for longer after eating, reduce hunger between meals, experience fewer energy slumps and feel more in control of cravings. Over time, this can also make healthy weight management feel easier.

Fibre works particularly well alongside protein. Including both fibre-rich foods and a source of protein at meals can help you stay satisfied for longer while supporting your energy, appetite and muscle health during midlife. You can find out more in my blog, Protein in Menopause: Why It Matters and How Much You Need. 

These benefits become even more valuable during midlife, when hormonal changes can make appetite regulation and weight management feel more challenging.

One thing I often remind clients is that small changes to the foods we eat can make a real difference to how hungry and satisfied we feel. Building meals around naturally fibre-rich foods is one simple, sustainable way to support your appetite and energy levels.

How Fibre Supports Your Heart Health

Looking after our heart becomes increasingly important during midlife. As oestrogen levels begin to fall during the menopause transition, many women notice that their cholesterol levels start to rise, even if their diet and lifestyle haven't changed. This is because oestrogen plays an important role in helping the body regulate cholesterol, so when levels fall, LDL ("bad") cholesterol often begins to rise.

Fibre can help here too. Some types of fibre, particularly the beta-glucans found in oats and barley, have been shown to help lower LDL cholesterol by reducing the amount absorbed from the digestive system.

Fibre-rich foods can also help support healthy blood sugar levels and make it easier to maintain a healthy weight, both of which contribute to a healthy heart.

How Fibre Supports Your Hormone Health

You might not immediately think of fibre when it comes to hormone health, but it has an important role to play.

Once hormones, including oestrogen, have been used by the body, they are processed by

the liver and prepared for removal through the digestive system. Fibre helps support this natural process by promoting regular bowel movements, allowing these hormones to be removed efficiently.

If bowel movements are infrequent and fibre intake is very low, some hormones may be reabsorbed rather than being fully excreted. Although fibre isn't a treatment for hormonal symptoms, eating enough fibre is an important part of a healthy diet that supports normal hormone metabolism.

Simple Ways to Eat More Fibre

Eating more fibre doesn’t have to mean completely changing the way you eat.  Small simple changes soon add up, and even one or two of the ideas below can make a real difference over time

At breakfast

• Add berries to your breakfast.

• Swap sugary cereals for porridge, overnight oats or muesli.

• Sprinkle nuts or seeds over porridge or yoghurt.

At lunch and dinner

• Choose wholegrains instead of refined grains, such as wholegrain rice, pasta, bread and couscous.

• Add beans or chickpeas to soups, casseroles and curries.

• Stir cooked lentils into salads or pasta sauces.

• Aim for an extra portion of vegetables with your evening meal.

• Add grated carrot or courgette into Bolognese, chilli or sheperds pie

• Try pearl barley in soups and stews.

• Choose oatcakes instead of crackers

• Add veggies to omelettes

For snacks

• Choose whole fruit rather than fruit juice.

• Snack on vegetable sticks with hummus or bean dip.

• Enjoy a handful of unsalted nuts or mixed nuts and seeds.

• Top natural yoghurt with berries and chia seeds.

• Try roasted chickpeas or edamame beans.

• Spread peanut or almond butter on apple slices or oatcakes.

Small changes really do add up

Fibre isn't about chasing a perfect diet or counting every gram. It's about gradually building more plant foods into your meals and creating habits that you can maintain for life.

Whether you start by adding berries to your breakfast, swapping to wholegrains or including an extra portion of vegetables with dinner, every small change is a step towards better health. Your gut, your heart, your hormones and your future self will all thank you for it.
