Some nutrients in our fruits, vegetables, meats are down by more than 76% since 1940

British studies shows that between 1940 and 1991 some nutrients in our food went down by 76%. I’m not talking about proteins or carbohydrates, but minerals. Also it’s not some green wash. It’s reality, simple math. Before… the stuff was there in certain amounts, now there is less of it. Reasons for that are multiple, I will talk about it the other time.

Change of nutrient content of British vegetables (on average) between 1940 and 1991:

  • Loss of 49% of their Sodium content
  • Loss of 16% of their Potassium content
  • Loss of 24% of their Magnesium content
  • Loss of 46% of their Calcium content
  • Loss of 27% of their Iron content
  • Loss of 76% of their Copper content

Change of nutrient content of British fruit (on average) between 1940 and 1991:

  • Loss of 29% of their Sodium
  • Loss of 19% of their Potassium
  • Loss of 2% of their Phosphorous
  • Loss of 16% of their Magnesium
  • Loss of 16% of their Calcium
  • Loss of 24% of their Iron
  • Loss of 20% of their Copper
  • Loss of 27% of their Zinc

Change of nutrient content of British meats (on average) between 1940 and 1991:

  • Loss of 30% of their Sodium
  • Loss of 16% of their Potassium
  • Loss of 28% of their Phosphorous
  • Loss of 10% of their Magnesium
  • Loss of 41% of their Calcium
  • Loss of 54% of their Iron
  • Loss of 24% of their Copper

Over the next few post we will talk about the reasons why did it happen and how to grow fruit, vegetables and how to raise animals that are rich in nutrients, vitamins and minerals.

    Hey Wojciech,

    Funny coincidence to see you’ve written this. A guy I know emailed me a PDF report about this same topic just 2-3 weeks ago. Extremely scary results, to be honest.

    I wonder if this could be used a strong sales point for the supplement industry (if they haven’t already picked up on it)

    It is scary indeed. But the worse it is, the better it is for me and supplement industry as you mentioned. It’s the whole lemon and lemonade thing as you probably know it!

    Thanks for the comment.

    Is it possible to increase the mineral content of the fruit or mineral with natural additives?

  4. Designer Ecosystems says

    Hi vanessa, it’s a really good question.

    The short answer is: yes.

    The long one will be this:
    Whatever makes your soil more balanced will make your and by that I mean: Are all elements in the right proportion? if yes the more nutrient dense will the fruit be. You can achieve that by using man made fertilizers or natural additives, though that stuff might be sometimes more expensive. Man made products have this advantage, that you know exactly what and how much certain elements are putting in your soil.

    For example if your soil has zinc or copper deficiency it would be difficult to raise your soil copper or zinc level without (for example) zinc sulfate or copper sulfate. Please check my last post about getting the benefits of rock dust without hauling tons of material. How I see it is this: You add micronutrients and trace elements as man made “chemicals”, then add some organic matter (compost, manure) for macronutrients. Top it up with some source of ultra trace elements (basalt rock dust, granite rock dust, seawater, sea salt) and you will be growing good to excellent food with high nutrient content. If you want to get to the Jedi-master level of nutrient density you will probably have to (on top of what I said before) use foliage feeding in certain times of the year to stimulate photosynthesis. Efficient photosynthesis means that soil microbes get a lot of sugars and lipids from the plant. And microbes “digest” rocks and minerals. When they die or when they poop they create a lot of organic substances, including amino acids. Then plants will get some of thous amino acids, so they don’t have to create them from scratch (using inorganic nitrogen).

    Good indicator, that you are doing something right is raised sugar content of your fruit if they are getting sweeter, then you are doing a good job. Get a refractometer (you can buy on amazon or ebay for about 20$), so you can check Brix level. This way you will know (and have quick feedback) are you growing nutrient dense fruit and vegetables or not. Before fruit is ready you can measure Brix level of the plant’s leaf, so you will know is the plant doing photosynthesis efficiently or not.
    I got this one:

    If you have any more questions I’m happy to answer them.

    Cheers!
