Is Weetabix High in Iron?

Want to know if Weetabix is high in iron? In a word ‘yes’, but carry on reading to know why this matters for you.

Iron is important for us all yet is the most common micronutrient deficiency in the UK today. Given its function reducing tiredness and fatigue this could maybe explain in part why many of us feel tired all the time.

Breakfast cereals are the single biggest contributor to iron in the UK diet, so you’ve come to the right place to find out more.

Why Your Body Needs Iron

Iron is found in our blood and muscles and is a real multitasker in the body. From helping to keep your blood normal and carry oxygen round your body, supporting your immune system, helping to reduce tiredness and fatigue and supporting your brain (cognitive) function it’s an all-star nutrient.

Mild iron deficiency may lead to looking pale, feeling tired and lacking in energy and possibly more frequent and longer lasting infections. Iron deficiency anaemia is severe iron deficiency. According to the British Dietetic Association, symptoms may include heart palpitations, brittle nails, thinning hair, itchy skin (pruritus) and mouth sores or ulcers.

How Much Iron Do You Need?

According to NHS UK the amount of iron you need as an average healthy adult is:

8.7mg a day for men aged 19 and over

14.8mg a day for women aged 19 to 49

8.7mg a day for women aged 50 and over

Pregnant women will need more whilst children will need the same, more or less depending on their age and sex. People with certain disease or health conditions may need more or less as advised by their health professional.

The National Diet and Nutrition Survey showed average iron intakes for girls aged 11 to 18 years and women aged 19 to 64 years were below the Recommended Nutrient Intake.

49% of girls aged 11 to 18 years and 25% of women aged 19 to 64 years had low iron intakes. Iron-deficiency anaemia (as indicated by low haemoglobin levels) and low iron stores (plasma ferritin) was recorded in 9% of older girls, 5% of adult women and 2% of older women.

A healthy balanced diet with a daily variety of foods should provide all the iron you need without needing to take supplements.

Weetabix & Iron: The Answer

Iron is a mineral naturally present in food, added to some food products (sometimes called fortification), and available as a dietary supplement.

Good food sources include fortified breakfast cereals beans and pulses like baked beans, red kidney beans, lentils and chickpeas, nuts and seeds, red meat, fish, eggs, tofu and other soya foods, dark green leafy vegetables, wholegrains and dried fruit such as apricots. Include a variety of these iron containing foods daily.

Fortified foods where iron is added make an important contribution to the UK population’s iron intakes. Take a bowl of Weetabix as a great example of an iron fortified cereal – a two bix serving provides over 30% (4.5mg) of the daily recommended intake for an average adult(14mg) as part of a healthy balanced diet and lifestyle.

Most other Weetabix brand cereals such as ready brek and Crunchy Bran are fortified too. Check the nutrition label when out shopping to make sure your cereal is a giving you iron-clad nutrition.
