Protein may dominate today’s nutrition headlines, but a growing number of health experts are pointing to another nutrient as the true cornerstone of lifelong wellness: fibre. In fact, women’s health physician and nutrition specialist Dr Jennifer Ashton recently described fibre as “the new protein,” highlighting the critical role it plays in digestion, metabolism, immunity, heart health, and hormone regulation.

Fibre is found exclusively in plant foods, including fruits, vegetables, legumes, whole grains, nuts, and seeds. Despite its abundance in whole foods, most people fail to consume enough each day. According to the information highlighted in the article, many women require roughly 20 to 30 grams of fibre daily, while men often need amounts in the mid-30-gram range. Yet most adults fall well short of those targets.

This deficiency matters because fibre influences far more than digestive regularity. Research continues to reveal connections between adequate fibre intake and healthy blood sugar regulation, cholesterol management, cardiovascular health, immune function, and metabolic well-being.

There are two types of fibre, and a healthy diet should contain both forms

Soluble Fibre: Soluble fibre dissolves in water, forming a gel-like substance in the digestive tract. It helps slow digestion and supports healthy blood sugar and cholesterol levels.

Insoluble Fibre: Insoluble fibre adds bulk to stool and helps food move efficiently through the gastrointestinal system, supporting digestive regularity and gut health.

Neither type works alone. Whole-food plant foods typically provide a combination of both, which is one reason nutrition experts consistently encourage eating a diverse range of minimally processed foods.

Fibre, hormones, and healthy ageing

One of the most intriguing developments in nutrition science involves the relationship between fibre, the gut microbiome, and hormone regulation. Emerging research suggests that adequate fibre intake may help regulate estrogen levels through a collection of gut bacteria known as the estrobolome. This connection may be particularly significant for women during menopause, when hormonal balance becomes increasingly important.

While scientists continue to study these interactions, the evidence already points toward a simple conclusion: a healthy gut supported by fibre-rich foods contributes to whole-body wellness.

The WFPB approach

Rather than relying on supplements, the most effective strategy is to obtain fibre from real foods. Dr Ashton’s daily breakfast demonstrates how powerful a whole-food approach can be. Her morning bowl includes flaxseeds, chia seeds, hemp seeds, wheat germ, cacao nibs, soy milk, and raspberries, providing approximately 15 grams of fibre before the day has truly begun.

The lesson is not that everyone should eat the same breakfast. The lesson is that intentional choices early in the day can dramatically improve overall fibre intake.

Excellent sources of fibre include:

• Berries, especially raspberries
• Chia seeds and flaxseeds
• Beans and lentils
• Whole grains such as oats and barley
• Nuts and seeds
• Vegetables of all kinds
• Fruits with edible skins and seeds

Building a fibre-rich day

A whole-food lifestyle makes fibre intake surprisingly achievable:

Breakfast: Oatmeal topped with berries, chia seeds, and ground flaxseed.

Lunch: A large salad featuring beans, vegetables, nuts, and whole grains.

Dinner: Lentil stew, vegetable-rich soups, or grain bowls with legumes.

Snacks: Fruit, nuts, seeds, or roasted chickpeas.

By spreading fibre-rich foods throughout the day, reaching recommended intake levels becomes far easier and more enjoyable.

No wellness fad

Fibre is not a trendy superfood or a passing wellness fad. It is one of the most essential components of a healthy human diet. From supporting digestion and heart health to influencing metabolism, immunity, and hormone balance, fibre touches nearly every aspect of well-being.

For readers committed to whole-food living, the take-home message is: prioritise plants, embrace variety, and make fibre a daily focus. The path to better health may not begin with a supplement or a special diet, but with a bowl of oats, a handful of berries, and a renewed appreciation for nature’s most overlooked nutrient.
