Are food preservatives bad for you? - Eleanor Nelsen
View full lesson: ed.ted.com/lessons/are-preserv...
Food doesn’t last. In days, sometimes hours, bread goes moldy, apple slices turn brown, and bacteria multiply in mayonnaise. But you can find all of these foods out on the shelf at the grocery store - hopefully unspoiled -- thanks to preservatives. But what exactly are preservatives? How do they help keep food edible? And are they safe? Eleanor Nelsen investigates.
Lesson by Eleanor Nelsen, animation by Compote Collective.

food with artificial preservatives definitely ain't as healthy as fresh food without them. but food with preservatives are definitely better than spoiled food, or lack of food at all.

I would like to note that BHT is not the same as vitimin E, rather it is a synthetic anolog of vitimin E. The species behaves as a synthetic analog of vitamin E, primarily acting as a terminating agent that suppresses autoxidation, a process whereby unsaturated (usually) organic compounds are attacked by atmospheric oxygen. BHT stops this autocatalytic reaction by converting peroxy radicals to hydroperoxides. It effects this function by donating a hydrogen atom: en.wikipedia.org/wiki/Butylated_hydroxytoluene

Fun fact: in portuguese preservatives , its very simular to "preservativo" wich is how we call "condoms". So I was like: how come TED can give us a lecture about the harm of condoms? Is this not counterproductive? Off course I miss ready it. In portugese food preservatives, we call it: conservantes.

Never knew
The intro to this video brought fear in me about mayonnaise having bacterial growth but on reading some research papers investigating the matter i am relieved to know that mayonnaise is not a bacterial culture medium & because of it's high acidity can actually never have an optimal environment for bacteria or fungi. Don't know why the video mentioned that at the start though? If anyone's gotta clue, enlighten me.

Mayonnaise, both commercially processed and home-made, has been associated with illnesses from Salmonella globally. The source of the Salmonella has been confirmed to be raw eggs.[64] Several outbreaks with fatal cases have been recorded, with a few major incidents. In a 1955 outbreak in Denmark, 10,000 people were affected by Salmonella from contaminated mayonnaise made by a large kitchen. The pH of the mayonnaise was found to be 5.1, with Salmonella counts of 180,000 CFU/g. The second outbreak, also in Denmark, caused 41 infections with two fatalities. The pH of the contaminated mayonnaise was 6.0, with Salmonella counts of 6 million CFU/g. In 1976 there were serious salmonellosis outbreaks on four flights to and from Spain which caused 500 cases and 6 fatalities. In the US, 404 people became ill and nine died in a New York City hospital due to hospital-prepared mayonnaise.[65] In all salmonellosis cases, the major reason was inadequate acidification of the mayonnaise, with a pH higher than the recommended upper limit of 4.1, with acetic acid as the main acidifying agent.[66] Some brands use pasteurized eggs which would reduce this risk factor

Mayo has long been thought in conventional wisdom to be something that goes bad quickly if left at room temperature, while the opposite is actually true. Poorly made mayo, as Magnum Lugo commented, was probably to blame, so perhaps this really was a much bigger problem 150 years ago when people used home-made mayo, but store-bought mayo will last safely quite some time.
a genuinely great video! amazing artwork and presentation of facts
was really helpful to figure out my problems with chips preservatives. thanks a bunch!
Thanks for making this video simple with the fun visuals and straightforward explanations. :-) The type of preservatives used is what we need to be wary about since most of our food is grown far away from the cities where majority if people live, so preservatives are necessary to a degree.

Also just like anti-vaccine claims of harm (and other food- and medical-linked pseudo-science, the claimed harms are also not found in the research. The only widely-used preservatives that have ever legitimately found to be harmful at any levels are sugars and salt. And it must be noted how those in appropriate amounts are not only safe, but absolutely vital. The closest anything else has been to get to the level of "maybe possibly having an effect on especially-sensitive people" are, as mentioned in the video, benzoates with ADHD.
Salted products are not as bad for you as we have believed. Most modern studies show that high sodium correlates with low mortality and low cardiovascular disease. The ideal amount seems to be around 12g salt per day.

So thank you for answering none of my questions.
Certain preservatives can lead to DNA damage (like the nitrates they spoke about) and cancer, our body has many processes to correct these damages. Each cell in our body has over 50,000 DNA damages every day, but most of us won't get cancer in our lifetimes, because we are evolved to correct these damages very well. We are not as good at fighting off bacterial infections that are very common from spoiled food. So while there is a small chance we will get DNA damage from certain preservatives, our body is much more capable of correcting that damage than it is of fighting off infection from bad food!

I am surprised that there is no mention of canning en.wikipedia.org/wiki/Canning - This is a way to kill the microbes and keep oxidation away without using chemicals. Drying (some times with the combination of salt) is also commonly used. Cooling was also used long before refrigeration was invented, see ice cutting en.wikipedia.org/wiki/Ice_cutting . There is a good overview of food preservation here en.wikipedia.org/wiki/Food_preservation
