'Protein hunger' drives overeating, large-scale population study shows:
A year-long study of the dietary habits of 9,341 Australians has backed growing evidence that highly processed and refined foods are the leading contributor of rising obesity rates in the Western world.
The new study, in the latest issue of the journal Obesity conducted by the University of Sydney's Charles Perkins Centre (CPC), was based on a national nutrition and physical activity survey undertaken by the Australian Bureau of Statistics (ABS), and further backs the 'Protein Leverage Hypothesis'.
First put forward in 2005 by professors Raubenheimer and Stephen Simpson, the Protein Leverage Hypothesis argues that people overeat fats and carbohydrates because of the body's strong appetite for protein, which the body actively favours over everything else. Because so much of modern diets consist of highly processed and refined foods – which are low in protein – people are driven to consume more energy-dense foods until they satisfy their protein demand.
[...] "It's increasingly clear that our bodies eat to satisfy a protein target," added Professor David Raubenheimer, the Leonard Ullmann Chair in Nutritional Ecology at the School of Life and Environmental Sciences.
"But the problem is that the food in Western diets contains increasingly less protein. So, you have to consume more of it to reach your protein target, which effectively elevates your daily energy intake.
[...] Participants with a lower proportion of protein than recommended at the first meal consumed more discretionary foods – energy-dense foods high in saturated fats, sugars, salt, or alcohol – throughout the day, and less of the recommended five food groups (grains; vegetables/legumes; fruit; dairy and meats). Consequently, they had an overall poorer diet at each mealtime, with their percentage of protein energy decreasing even as their discretionary food intake rose – an effect the scientists call 'protein dilution'.

A more realistic concern is that they'll use incomplete proteins (those lacking in essential branched amino acids) since the regulator will "mistakenly" forget to require them to balance them out.
It's a common problem with plant based protein powders marketed to vegetarians.

We had a problem around 2007, when China used Melamine, an industrial chemical which contains Nitrogen, to economically fortify cat food so as to increase the protein assay to be reported on the label.
I am aware as I lost a momma cat and a litter of kittens to it.
Infant formula was also involved. Thousands of Chinese infants also lost kidney function and have to dialysis.
Messing around with synthetic foods is risky!

A link to the recall list:

Both me and my neighbor lost cats. All of them had an unmistakeable odor prior to their passing.
We both fed our cats the same stuff...which was on that list
By the time the renal failure was diagnosed, the cats were goners.
Again, I post this as a reminder to manufacturers to be extremely cautious about screwing around with edibles, as even the melamine at the time appeared just an economical way to make numbers look better for the protein assay.

As I've already mentioned here [soylentnews.org] and here [soylentnews.org], the flour and rice on the shelf that you eat every day are already extensively engineered products that are fortified with multiple chemicals in the same manner. Besides, baby formulas and pet food are fundamentally engineered product since different animals and especially infants have different macro and micro nutrients needs than adult humans so formula and pet food factories are in the business of taking various products and powders and mixing them to get the right numbers.

Yup. Those of us who are aware of this stuff need to bring it into view every chance we get!
Thanks! From all of us!
