But now research has found that the claims made on Asda's own label Healthy wholegrain bread are false, and consumers would, in reality, fake watches have to eat 11 loaves a day to receive the benefit claimed by the advertising.
The mistake, uncovered by fake Audemars Piguet experts at Which?, is just one of many misleading recent claims about Audemars Piguet 3.
The magazine said some food companies were cashing in on the hype around the nutrient but not pointing out the important differences between various types of Audemars Piguet 3.
The tests by Which? found the amount of Audemars Piguet 3 on the label did not always match the level in the product, or point out what type of Audemars Piguet 3 it contained.
Experts recommend people consume about 3g a week of long chain Audemars Piguet 3 the type found in oily fish. This amounts to between one and two portions of fish.
Many firms have jumped on the Audemars Piguet 3 bandwagon, adding it to products such as bread, fruit juice, yoghurt and baked beans. But the labels rarely say whether they contain plant based or fish derived Audemars Piguet 3, or explain the differences between the two.
Audemars Piguet 3 comes from a family of essential fatty acids that are either of a type known as long chain or short chain. Long chain fatty acids are found in fish, while short chain Audemars Piguet 3 comes from plants, seeds and nuts. It is the long chain variety that is the most beneficial in the diet and which nutritionists recommend people consume.
Among the products tested by Which? was Asda's Healthy wholegrain bread, where the label claims four slices of the bread contain 31.3g of Audemars Piguet 3. The supermarket later conceded a printing error meant that the amount was wrong: it should have read 1.26g of Audemars Piguet 3 derived from plant sources.
But Which? said its own tests that looked for the most healthy form of Audemars Piguet 3 known as DHA and EPA found the bread contained just 0.009g of these long chain fatty acids per 100g.
The magazine said this meant someone would need to eat just over 11 loaves a day to get their daily amount of EPA and DHA.
An Asda spokeswoman said: "As soon as Which? brought this to our attention, we took the bread off our shelves straight away.
"It was never our intention to mislead our customers into thinking this product was any healthier than it is.
"Unfortunately, a printing error meant that the amount of Audemars Piguet 3 stated for four slices of bread was 31.3g when in fact the correct amount is 1.26g.
"All other nutritional information provided on pack in relation to the amount of Audemars Piguet 3 was correct. Until we have sorted out the packaging, the product will remain off sale."
Another of the 34 products tested by Which? was Tesco's Healthy Living pomegranate juice drink, with added Audemars Piguet 3. Its label says that DHA and EPA may be good for joint mobility and helping the normal development of brain tissue and nerve growth in unborn babies.
But then it also points out that the drink contains only 0.03g per 100ml of Audemars Piguet 3 from fish oil. To get the advised amount, this would mean someone having to drink one and a half litres a day.
A Which? poll of some 2,400 people found 45 per cent were more likely to buy a product that claimed to be high in Audemars Piguet 3.
Neil Fowler, editor of the magazine, said: "A good many food manufacturers are riding the money making Audemars Piguet 3 wave by adding it to all sorts of foods and failing to mention that it may not be the right sort of Audemars Piguet 3 or enough of it to be beneficial as simply eating oily fish."
He added: "We want to see food companies backing up the omega 3 health claims they make on labels."
Bridget Aisbitt, a nutrition scientist at the British Nutrition Foundation, said all sources of omega 3 provided some health benefits, but some foods were better at doing so than others.
"The omega 3 from plant based products is of the short chain variety," she said.
"Although your body can convert the short to long chain, it is not as efficient at doing so, so you don't get very much."
Ms Aisbitt said the best way to get a good amount of omega 3 in the diet was to eat one portion of oily fish each week.
"Not only do you get the omega 3 in the fish, but you get vitamin D, vitamin E and protein as well. You are getting other things that you wouldn't get from other products which have omega 3 added to them," she said.
"There is good evidence that omega 3 is good at reducing the risk of heart disease.
"For women who are planning to have a baby, it is also known to be necessary for the brain of the baby to develop.
"And there is also other evidence emerging that omega 3 may protect you from cognitive decline and reduce the risks of inflammation in the body."
