15 foods that were kitchen staples in the 1970s but are now banned or heavily restricted

Those in the UK don't need to fear, this Scottish delicacy is still a regular guest for Burns Night. The US isn't quite so keen, however, and the food is banned on their side of the Atlantic.

Since 1971, the USDA has banned sheep lungs from being used as an ingredient so it's illegal to make or even bring back a taste of the Hebrides. 

This popular plate was sadly hoisted on its own line as overfishing in the '80s led to a ban on commercial fishing in the US. 

The most popular recipe was coined by chef Paul Prudhomme, whose blackened redfish featured a mild flavour that showed off his mixture of cayenne, paprika, thyme and oregano perfectly.

Some food bans might be easily sniffed at but foie gras is certainly better left in the past. Ducks and geese are force-fed which can cause their livers to swell up to 10 times the size. 

The practice has been banned in the UK since 2006 under the Animal Welfare Act though it is still imported from across Europe and considered a delicacy by many.

Bold and beautiful, dyed pickled eggs in the '70s were a sight to behold. Synthetic dyes meant these neon treats could be seen from space, thanks to pigments like Red No. 2 and Yellow No. 5. 

Unfortunately, they were later linked to allergic reactions and hyperactivity and some dyes included were later restricted or banned.

Resin, pulp and... noodles? Formaldehyde has plenty of uses today, but its days in food preservation are long gone. 

Some instant noodles were treated with trace amounts of formaldehyde which, we now know, posed serious health risks. It wasn't long before formaldehyde was strictly prohibited worldwide.

Asbestos had a multitude of uses before we knew of its harmful effects, from snow in The Wizard of Oz to attic insulation. 

But in the '70s, asbestos was used as a filter aid in breweries to remove impurities and clarify beer. By 1979, some producers were still using the substance in their production, which was phased out in the 1980s. 

There's a cartoon-worthy domesticity about carving your Sunday roast straight off the bone. But during the mad cow disease outbreak, and this weekend centrepiece disappeared for a while as the government stepped in to temporarily ban beef on the bone in 1997, before lifting the restrictions in 2000. 

As the Monty Python crew said: 'Always look on the bright side of life'. But for 1970s breakfasts, a subdued hue of sunshine yellow would have been the healthier choice. 

Coal tar dyes transformed the pale spread during the winter months, but their use was phased out due to health concerns, including toxicity and potential carcinogenicity.

Canned fruit and condensed milk? Yes please! While the syrup-sweetened fruit still feels like a treat today, in the 1970s many were packed in artificially sweetened syrups.

For dieters, the additives felt like a great alternative but studies linked overconsumption of some of these additives to health risks, with artificial sweeteners now regulated.

Nowadays, raw milk might bring to mind extreme diets but unpasteurised milk was run of the mill during the '70s. 

Bacteria like E.coli have since put raw milk under tight control, with some artisanal versions still available, but it'll take much more than a mooch round your local store.

In the 1970s, the handling of shellfish without consistent refrigeration was common and it was readily available. It risked containing algal toxins and harmful bacteria. 

Fortunately, prawns and the like are much more carefully tested nowadays. So go ahead and slather a cone in cream cheese for your shellfish celebration.

Remember those cloudy fruit drinks from the '70s? You might not as they contained brominated vegetable oil to stop the fruit flavours separating. 

Bromine build up was later discovered and can potentially cause memory loss and skin issues. The US banned BVO in 2024 but the UK bid farewell to the citrus drink additive in 1970.

Dieters from the '70s listen up: that sweet Panda Pop you used to wash away the lingering taste of a halved grapefruit wasn't as innocent as it seemed. 

After testing revealed some potentially serious illnesses linked to Cyclamates, they were banned in the US and UK but were later re-approved for use in the UK, and currently labelled as a food additive (labelled as E 952) within strictly regulated limits.

The Space Race got shoppers a little overexcited about preservatives and the following decade ensured there were plenty of tinned goods in stock. 

Sadly, the lead solder used to seal the cans meant small amounts would follow into your pineapple upside-down cake. Fortunately, lead solder is banned and you can crack open that tin of beans without a care in the world.

Freddie wasn't the only Mercury around during the '70s. When unfolding their soggy newspapers on a Friday night, consumers would likely find shark and marlin nestled in a bed of chips. 

These species are now known to build toxic mercury due to their predatory diet. There's now consumption advice for those who fancy a particular slice of fish, but otherwise maybe go for with a battered sausage.
