For the healthiest breakfast of all, cook up a kipper and ditch sugary cereals, orange juice and toast, gut health expert says

Lovers of the full English or a plate of kippers in the morning may have cause to celebrate.

Apparently we should all be eating a savoury breakfast to stay healthy – and should ditch sugary cereals, orange juice and toast.

This would avoid the daily ‘rollercoaster’ of sugar highs and lows, according to a leading gut health expert.

Jessie Inchauspe, a French biochemist, said the British have been duped into reaching for sugary breakfasts by ‘marketing which has lied to us for decades’.

She said she would ‘eradicate orange juice’, which has been sold as healthy, despite typically containing around seven teaspoons of sugar per glass.

Eating savoury dishes first thing keep us full for longer, stopping us from snacking to get the next sugary fix. No foods are off-limits but need eating in the right quantities and at the right time of day, she added.

She told Randox’s Cost of Poor Nutrition conference: ‘People have told you for a very long time ‘have an orange juice in a morning, it will give you energy’, ‘breakfast should be sweet – it should be pastries, cereal’ but it’s all lies.

‘Eating sweet breakfasts was invented by the food industry just to make money because breakfasts are very profitable.

‘The best breakfast is a savoury breakfast that is based around protein. Protein is a very important substance to eat to keep you very satiated, the body needs it and we don’t eat nearly enough of it.

‘You can have leftovers from your dinner for breakfast – so maybe you had fish, veg and fritters – have that instead.

‘The full English breakfast is actually not too bad if you make it at home and it’s not processed.’

Jessie Inchauspe says that ditching sugary breakfast foods for savoury options is advisable

The author, whose book Glucose Goddess was serialised in the Mail earlier this year, said sweet breakfasts lead to less circulating energy.

People then experience a sugar – or glucose – low, which can cause tiredness, hunger and also increase cravings. By switching to something with more protein, such as egg, fat like avocado or oily fish, and fibre from vegetables, the body would get more steady energy and avoid a ‘crash’.

Food campaigner Dr Chris van Tulleken, speaking at yesterday’s conference at Goodwood House in Chichester, said sugary foods ‘interrupt our ability to say I’m full’, with breakfast cereals being some of the worst offenders.

It comes after landmark research revealed Britain is facing ‘a tidal wave of harm’ from ultra-processed food, with millions at risk of heart problems. A study presented at the European Society of Cardiology Congress found those who eat the most mass-produced foods are 24 per cent more likely to suffer a heart attack and stroke.
