Many women are surprised to learn that they may not be getting enough fibre. Despite fibre being an essential part of a balanced diet, most UK adults consume significantly less than the recommended 30g per day. Yet because low fibre intake often develops gradually, many people don’t immediately recognise the signs you need more fibre. Here we explore:

---

What Is Fibre?

Fibre is a type of carbohydrate found in plant foods that the body cannot fully digest.

Unlike other carbohydrates, fibre passes through the digestive system largely intact.

There are two main types:

Soluble Fibre

Soluble fibre dissolves in water to form a gel-like substance.

It can be found in:

• Oats
• Psyllium husk
• Apples
• Citrus fruits
• Beans
• Lentils

Insoluble Fibre

Insoluble fibre adds bulk and helps food move through the digestive system.

Sources include:

• Whole grains
• Vegetables
• Nuts
• Seeds
• Wheat bran

Most fibre-rich foods naturally contain a combination of both types.

How Much Fibre Do Women Need?

According to NHS guidance, adults should aim for approximately 30 grams of fibre per day.

However, surveys suggest average intakes are often much lower.

Women may fall short of their daily fibre needs due to:

• Busy schedules
• Skipping meals
• Low vegetable consumption
• Frequent consumption of processed foods
• Restrictive dieting patterns

Common Signs You Need More Fibre

Low fibre intake does not always produce obvious symptoms. However, several signs may indicate that your diet could benefit from more fibre-rich foods.

1. Your Diet Contains Few Fibre-Rich Foods

One of the clearest indicators is simply looking at what you eat.

If a typical day contains:

• White bread
• Refined cereals
• Processed snacks
• Limited fruit
• Limited vegetables

then your fibre intake may be lower than recommended.

Compare these examples:

Lower Fibre Choices	Higher Fibre Choices
White toast	Wholegrain toast
Sugary cereal	Porridge oats
Crisps	Nuts and seeds
White rice	Brown rice
Biscuits	Fruit and berries

Small swaps can gradually increase daily fibre intake.

2. You Rarely Eat Fruits and Vegetables

Fruit and vegetables are among the most important contributors to dietary fibre.

The NHS recommends at least five portions per day, yet many adults consume fewer than this amount.

If vegetables only appear occasionally on your plate, increasing your intake may help improve overall dietary fibre consumption.

---

3. Your Meals Leave You Feeling Less Satisfied

Fibre-rich foods often require more chewing and take longer to digest than highly refined foods.

Meals containing:

• Vegetables
• Whole grains
• Beans
• Lentils
• Nuts
• Seeds

can help create meals that feel more substantial and satisfying as part of a balanced diet.

---

4. You Frequently Choose Convenience Foods

Modern diets often contain highly processed foods that are lower in fibre.

Examples include:

Lower Fibre Option	Higher Fibre Alternative
White pasta	Wholewheat pasta
White bread	Wholegrain bread
Refined breakfast cereal	Oats or muesli
Sweet snacks	Fruit and nuts

While convenience foods can fit into a balanced lifestyle, relying on them heavily may reduce overall fibre intake.

---

5. You Struggle To Reach The Recommended 30g Daily

Many women simply do not realise how much fibre 30 grams actually is.

A typical high-fibre day might include:

Meal	Fibre-Rich Foods
Breakfast	Porridge oats, berries, flaxseed
Lunch	Wholegrain wrap, salad, chickpeas
Snack	Apple and almonds
Dinner	Lentil curry with vegetables and brown rice

Tracking your food intake for a few days can help determine whether you’re reaching your target.

---

6. You Follow Restrictive Eating Patterns

Some restrictive diets can unintentionally reduce fibre intake.

Examples may include:

• Very low-carbohydrate diets
• Diets that exclude grains
• Diets low in legumes
• Highly processed meal replacement plans

If entire food groups are excluded, fibre intake can sometimes fall below recommended levels.

Key Takeaway

Many women consume less fibre than recommended without realising it.

If your diet contains limited fruits, vegetables, legumes, nuts, seeds and whole grains, increasing your fibre intake may be worth considering. Starting with fibre-rich foods and making gradual dietary improvements can help support overall dietary balance and digestive wellbeing.

For those who struggle to meet daily fibre needs consistently, fibre supplements may provide a convenient way to complement a healthy lifestyle.
