new research debunks trad views on nutrition

[Penpal]

Thank you, Altairsky. I enjoyed the video. Well done, he tells you exactly what you need to know without a long preamble.

I think that if chickens free range they would probably get enough insects to supplement a 16% layer feed, so if you free range your results may vary.

thanks for those; very interesting.

“In the first test, you can see the males are spending more time and resting more in the center of the arena. In females, we saw changes in novel object recognition,” Ross said. “In human Alzheimer’s patients, men tend to experience more changes in apathy; they care less. Women experience more changes in memory. So the memory and the apathy connection are pretty clear: When you expose animals that are carrying the largest known risk factor in humans for developing Alzheimer’s disease to micro- and nanopastics, lo and behold, their behavior changes in a sex-dependent manner similar to the sex-dependent differences we see with Alzheimer’s patients

Cheap meat may cost us all more than we thought and expected:

So this is promising: a nutrient density meter is in development

It covers a lot of the bases, but misses the role of different (especially old) varieties of 'the same' fruit or vegetable, on which Jo Robinson, Eating on the wild side, 2013 cast so much light.

I thought the group here might be interested in this scientific study that I originally found on the NIH website.

I think it is free. If not, I can post as a PDF.

Here is one paragraph to whet your appetite(!):

A second reason why an unprocessed diet might promote lower energy intake is that meal components may be selected for nutritional qualities other than calories. Early studies in chickens [8], pigs [9], and rats [10] showed that animals grow as well or better when provided free access to a cafeteria diet compared with formula feed. Building on this, Rozin [11] and Provenza [12,13] showed how species adjust their dietary choices to alleviate specific micronutrient deficiencies. Recently, we reported that humans might show a similar tendency, preferring specific pairs of fruit and vegetables that deliver a broad range of micronutrients [14]. Because fruits and vegetables are rich in micronutrients, yet low in energy density, we reasoned that consuming these components might lead to less calorific meals [15,16]. Thus, “micronutrient seeking” might be an additional factor contributing to lower energy intake from unprocessed meals in Hall et al.’s [1] study.

This is so wrong on so many levels I don't know where to start.

I read the whole article and for the life of me can’t decide if they are saying the tension between getting micronutrients and calories with unprocessed foods is a problem or beneficial.

 

[RoyalChick]

They aren’t putting a value judgement on it. They are saying that with unprocessed food people naturally select food that gives them the micronutrients the body needs and that because a lot of those micronutrients come in foods that are relatively low in calories people on a diet of unprocessed food will eat fewer calories.
For people in the West where obesity is an issue that would generally be a good thing.
It is also interesting from a chicken perspective because it supports the theory that given enough variety of available foods (not easy here right now under a lot of snow), a chicken can select a healthy diet for itself.
