The partner of a New Zealand woman who died at just 34 years of age says she drank two litres of Coca Cola a day.

Amy Louise Thorpe, from the South Island city of Invercargill, was addicted to the popular fizzy drink, he told a coroner holding an inquest into her death.

The mum-of-three died of an epileptic seizure two years ago.

Her consumption of the caffeine-laden beverages were considered as potential factors in the hearing probing her death, reports Stuff.

The inquest was told the young woman drank two litres of Coke almost every day, and additionally consumed up to a litre of energy drinks daily too.

The New Zealand mum consumed litres of the soft drink daily

She was found unresponsive in her Invercargill home on December, 4, 2018.

Findings delivered this week say her soft drink consumption may have contributed to her death.

Samples of Ms Thorpe's blood and urine analysed after her death reportedly uncovered the presence of caffeine and nicotine.

A report released by Coroner David Robinson said she smoked around 80 grams (2.8oz) of tobacco a week.

He noted she had a history of epilepsy and was up to date with her medication, but her most recent seizure had been just three days before her death.

Ms Thorpe also suffered from depression, anxiety and sleep apnoea, the report said.

Mr Robinson's report said she had a raised body-mass index and a history of gestational diabetes.

A coroner and neurologist considered the role of her Coke consumption in her death

Ms Thorpe's partner described her as being "addicted" to Coca-Cola.

He told police his partner consumed advising police consumed on average two litres a day, along with around 500ml to1 litre of Mother branded energy drink a day.

A friend, Madonna Bresolini-Meikle​ provided a statement to police.

According to Stuff she said: "Amy had more energy drinks a day than people have coffee. She enjoyed her V drinks and Coke".

The coroner considering her death referenced research linking high caffeine energy drinks to seizures in adults.

A neurologist consulted for the inquest added that research on the phenomenon was divided and described the data as "lacking."

He said some studies suggesting caffeine intake could increase seizure susceptibility, while others found it could potentially protect against them.

However caffeine was also shown to inhibit anti-seizure drugs commonly used to manage epilepsy, such as Topiramate, he added.

Sales of energy drinks will be limited to under-16s in the UK soon

Dr Graeme Hammond-Tooke​ said: "In the case of Ms Thorpe, I think it is possible that excessive caffeine contributed to poor seizure control. While modest intake of caffeine contained in drinks is not likely to affect seizure control, large amounts probably do increase seizures, and may have other adverse effects on health".

The coroner encouraged the case to be publicised, saying people with epilepsy and doctors advising them should should be made aware of potential consequences from using too much caffeine.

A tribute page for Ms Thorpe described her as a 'much-loved' mum-of-three and partner.

Her case bore similarities to another death in the same city in 2010.

A coroner found Invercargill mum-of-eight Natasha Harris' death was also linked to excessive Coke consumption after she drank up to eight litres a day for several years before she died.

At the time, Coca Cola denied its product played any proven role in the 30-year-old woman's death.

Supermarkets have already limited sales of high caffeine energy drinks to youngsters

Meanwhile, the UK is banning the sale of energy drinks to children following a campaign backed by teachers unions and stars including celebrity chef and sugar-tax advocate Jamie Oliver.

In 2018, major food retailers Waitrose, Sainsbury's, Morrison's, Co-op, Tesco, Aldi, Asda and Boots all announced they were limiting sales of energy drink sales containing more than 150mg of caffeine to under-16s.

The government's ban will mean inder-16s will not be allowed to buy high caffeine drinks such as popular Monster and Red Bull anywhere.

The ban is part of a government plan to halve childhood obesity by 2030 and address health issues linked to deprivation and unhealthy lifestyles, but has attracted complaints of 'nanny-statism' from some critics.

The policy announcement was rushed out last July before Prime Minister Boris Johnson took power amid a Tory row about 'sin taxes,' with the details said to be yet-to-be fully worked out.
