Is Our Food Becoming Less Nutritious? 1 day ago   07:30

Veritasium
The nutrient content of food is declining. Is it because of soil depletion, selective breeding, or... something else?
Watch my new documentary, VITAMANIA: http://ve42.co/vita

I came across this story as I was making the film Vitamania. When you ask sellers of vitamins why you should take vitamin supplements even if you eat a healthy diet, they will say because our food doesn't contain all the nutrients it once did. This is supposedly due to soil depletion, cold storage, food ripening off the vine, and global transport of out-of-season foods. And to an extent this is true. Foods contain the greatest amount of nutrients if they are eaten soon after they are harvested. An unexpected source of nutrient decline is the increasing amount of carbon dioxide in the atmosphere. It causes plants to grow faster and bulk up on carbs but at the expense of other nutrients, so in percentage terms the amount of nutrients are actually declining. For now this decline is modest so supplementing with vitamin pills is probably unnecessary for most people with a healthy diet but it may be a concern in future.

Idk man but everything is starting to taste the same to me.... excluding fresh produce

is not the food industry just selecting/genetic engineering fruits and vegetables for good looks and resistance to aging and transportation that are visible when you purchase it in the shop and not for taste and nutritious content that is invisible to the eye ?

Love your videos, are you still making them?

Why do you not consider carbohydrates as nutrients? It's where the energy for everything else comes from. I'd argue that carbohydrates are the most important nutrients of all.

No mention of roundup/glyphosate which chelates minerals in the plant and soil, Roundup is ubiquitous and has been found in 75% rain samples taken from all over the world . https://detoxproject.org/glyphosate/glyphosate-chelating-agent/

pra-duce.. looser. I really hate this guy.

so the plants are getting fat..

Stay away from perfect looking fruits&vegetables.

Not only the good minerals are depleted but bad minerals has been deliberately added into the food chain. Chemtrail containing aluminium compounds are sprayed regularly in the air and then settled on surface soil where it is taken up by the fruits and vegetables we eat. Aluminium is implicated in Alzheimer's disease. A insidious plan to make the masses stupid so they won't be able to rebel big brother One World Order. The only problem standing in their way now is just Russia and China.

Even table salt uses anti-caking agents like sodium aluminosilicate (E-554). So whenever you eat out whether at a five star restaurant or at a fast food joint, you are guarantee to have the salt used in your food mixed with aluminium compounds in it. No one in the food industry is going to use expensive Celtic sea salt in the foods they serve you. Even if you were to eat a package of chips or French fries at MacDonals or a piece of salty cheese or a store bought pickled gerkin and so forth, you will inevitably accumulate aluminium inside your brain.

And then if you get heart burn from eating all those junks, then heart burn medications will put more aluminium into your body in the form of aluminium hydroxide. As if that's not enough for you, your caring doctor will want to vaccinate you each year with vaccines loaded with aluminium and mercury compounds. Sounds like the entire social system is deliberately set up to make people stupid and demented so they can be easily controlled and manipulated.

I guarantee if you take two of the same veggies from the same seed and plant one on an industrial farm and I plant one in my garden it will be way more nutritious. Large scale farmers aren’t taking nearly as good care of there soil as you think. Spraying chemical fertilizers isn’t good enough. I farm my soil and let the soil grow the produce.

if the content of protein in golden rod went down 30% what replaced it? is there more carbohydrates and fat instead? (Since it has access to more CO2 it stores more energy and synthesizes less protein?)
wriker36
Life was supposed to have ‘flourished’ during the times where CO2 was around 1,000 parts per million as appose to the 400ppm we currently have. Does that mean plants then were practically void of nutrition? Also some say if CO2 falls too low than todays levels, plants will practically starve? Is it just before this stage they are at their most nutricious? Why is it that plants, when fed well with CO2 lose their nutrition then? Is CO2 just a ‘speed growth’ thing?

Sad. I’m hearing mixing of studies. Too bad. It really sounds like a schizophrenic presentation.

The video is a grab bag of studies to make a point. The point is understood... but the multiple studies don’t point to the point.
starrychloe
Maybe bees aren’t getting protein and vitamins and collapse?
codeshot
30% decrease in pollen protein != decrease in wort protein. Also, a 30% decrease in pollen protein can be achieved by a decrease in pollen which can happen for all sorts of good reasons like maybe it's easier to reproduce now, or a factor changed in a way that was evolutionarily associated with easier reproduction so the plant adjusts with that marker.

Could really do with more substance before any conclusions can be drawn.

Every interesting. Thank you

In USA? For sure. U suck regarding food consciousness and health. Your business and level of life r heavy daily polluters and that is the main concern.

Then why is there so much obesity? Its never been a better time to be alive you retard.
