Biscuits, chocolate bars, crisps and sausage rolls are likely to surge in price, if a proposed tax on sugar and salt is implemented by the UK government.
The world's first Salt and Sugar Reformulation tax could be introduced in England as part of a new National Food Strategy.
The report also suggested doctors should be able to prescribe fruit and vegetables as what we eat is doing "terrible damage" to the health of the country. Money raised from the sugar and salt tax would be used to fund this, the report suggests.
Poor diets are contributing to around 64,000 deaths each year in England, according to the National Food Strategy published on Thursday.
The independent review, commissioned by the government in 2019, has urged ministers to carry out major reforms to help people cut down on sugar, salt and meat to save lives.
So which favourite chocolates, biscuits and snacks could go up in price?
The report suggests the new taxes would be applied to wholesale sugar and salt purchased by manufacturers, which could in turn raise some prices on shelves.
Recommendations to prices from the National Food Strategy give examples such as a Dairy Milk chocolate bar (25g) - which currently costs 60p - could increase by 13% to 68p under the new levy.
If the reforms are implemented, other changes will include a pack of Salt and Vinegar Pringles (200g) will go up by 1% from £2.50 to £2.53.
The Daily Mail reported a 51g Mars bar costing 60p could jump to 69p under the Sugar and Salt Reformulation Tax.
A Greggs sausage roll could also rise by 1p to £1.20 under the proposed tax changes.
A packet of McVities Milk Chocolate Digestives (266g) could increase from £1.60 to £1.84, if the tax is introduced.
A packet of Walkers Ready Salted Crisps (45g) could increase by a penny from 85p to 86p.
A box of Kellogg's Frosties (750g) could soar from £3 to £3.87.
And a pack of eight Mr Kipling's French Fancies faces a 39p price increase from £2.10 to £2.49.
What has the author of the report said?
"The idea of the tax is like the sugary drink tax in that it doesn't end up putting up the price of things, it takes more of the bad stuff - more of the sugar and salt - out of highly processed food," food entrepreneur and report author Henry Dimbleby told ITV News.
He added: "It's only going to be charged on processed foods."
He said: "We have modelled what it would do - depending on what reformulation there was, to the household basket of food for the average family and any increase to prices are likely to be very low indeed."
The idea is that any price rises would encourage manufacturers to reduce the amount of sugar and salt in items, rather than passing the cost on to consumers.
"It's a big problem and we have to have bold solutions and I wouldn't expect the prime minister to make up his mind on day one, not having read the full report," Mr Dimbleby said.
Earlier on Thursday, Boris Johnson said he was not "attracted to the idea of extra taxes on hardworking people".
What else is in the report?
The report has said the proposed tax could lower the average sugar intake by 4-10g per person per day, and the salt intake by 0.2-0.6g per person per day, cutting the average calories eaten per person per day by 15-38 kcal.
This could completely halt weight gain at a population level - which would require an average reduction of 24 kcal per person per day.
