NUTRITIONIST'S INSIGHT

Weetabix is a plain wholegrain wheat biscuit, 95% wholegrain wheat with a little malted barley extract, sugar and salt, so the label is short and the sugar is low. At 136 kcal for two biscuits it is a light breakfast, and the numbers change mostly through what you pour on it: milk, sugar, honey or fruit. The 3.8 g of fibre covers roughly a seventh of the 25 to 30 g a day most health guidelines recommend for adults. The 4.5 g of protein is modest, so add milk, yoghurt, eggs or nuts if you want the breakfast to last until lunch.

Myth Busters

MYTH #1: Weetabix is full of sugar.

TRUTH: The UK label shows 1.6 g of sugars per two biscuits (4.2 g per 100 g). Most of the carbohydrate is starch from wholegrain wheat. The bowl gets sweeter only if you add sugar, honey or sweetened milk. Weetabix Original: nutrition, ingredients and serving size

MYTH #2: Two Weetabix is a complete breakfast.

TRUTH: Two biscuits give 136 kcal and 4.5 g of protein, which is a light start. Milk adds protein and calories, and many people eat three or four biscuits. Adding fruit, yoghurt or nuts makes it more filling. Weetabix Original: nutrition, ingredients and serving size; Starchy foods and carbohydrates

MYTH #3: All Weetabix products have the same nutrition.

TRUTH: Weetabix Original is 362 kcal per 100 g. Weetabix Protein is 365 kcal per 100 g and its 2-biscuit serving is 40 g, not 37.5 g. Check the box for the product you are eating, because the Minis, Protein and overseas versions use different recipes.

MYTH #4: Wholegrain cereal gives you all the fibre you need.

TRUTH: Most health guidelines advise adults to eat 25 to 30 g of fibre a day, and most people eat around 20 g or less. Two Weetabix supply 3.8 g, so they help but need to be combined with fruit, vegetables, pulses and other wholegrains across the day.

Blood Sugar Response to Weetabix

Two biscuits have 26 g of carbohydrate, almost all of it starch, with 3.8 g of fibre and 1.6 g of sugars. Eaten with milk, expect a moderate rise of about 30 to 40 mg/dL that peaks around 45 to 60 minutes and settles within 2 to 3 hours. We found no published glycaemic index value for Weetabix, so this curve is a modeled estimate based on the carbohydrate and fibre content. Extra sugar, honey or a large banana will lift the peak.

Estimated Blood Sugar Response (2 biscuits with milk)

Modeled estimate for a person without diabetes, not a measured trace and not a tested GI value. Individual responses vary with portion size, milk, toppings and activity.

How to flatten the spike

Eat it with milk, plain yoghurt or a boiled egg so protein and fat slow the carbohydrate.
Stick to two biscuits and measure toppings, since each extra biscuit adds about 13 g of carbohydrate.
Top with berries or nuts rather than honey, sugar or dried fruit.
Take a 10 to 15 minute walk after breakfast to blunt the peak.
If you monitor glucose, test your own response once with your usual bowl before making it a habit.

Cultural Significance

Weetabix has been made in Burton Latimer, Northamptonshire since 1932, when Bennison Osborne and Malcolm MacFarlane set up the British and African Cereal Co in a disused flour mill. The company took the Weetabix name in 1936. Weetabix says it sources its wheat within 50 miles of its head office and it is a standard British breakfast, often eaten soaked in cold or hot milk. The recipe has Australian roots: the pressed wheat biscuit was developed there in the early 1900s, and Weet-Bix is still sold in Australia under a separate recipe.
