If you’re looking for a good source of protein and calcium, look no further than chickens.
As far as the rest of us go, the birds are in the clear.
They are also a huge part of our diet.
“It’s the only meat we eat, and the only one that’s free of toxins and antibiotics,” says Mark Larkin, professor of veterinary medicine at the University of Oxford.
In fact, a study conducted in 2008 found that nearly half of all birds consumed their diet entirely from the wild.
The meat is sourced from all parts of the animal’s body, from the bones of the chicken to its liver, and its bones, which have a special coating that keeps the meat from drying out.
But it’s the liver, which is the most prized part of a chicken, that is where most of the research into the health of the bird lies.
This part of the diet has been studied for more than 20 years, and is still largely unknown.
In the 1950s, Dr. Paul Siegel and colleagues used to measure the levels of arsenic in chickens, but now, because the liver is an area of concern, this research has been discontinued.
It was found that levels of the toxic substance in the liver varied from a single-digit to almost a hundred times higher than those in the rest and throat.
The research was published in 1974, and since then, studies have found that the liver contains more arsenic than the rest, and that the arsenic levels in chickens are often higher than what humans find in their blood.
The new research was carried out by scientists from the University in the UK, the National University of Singapore and the Australian National University.
The aim of their study was to find out what happened to the liver of chickens in the wild, so they could compare their levels of toxicity and the amount of arsenic they absorb.
The researchers examined a total of 50 different wild chickens and found that about a quarter of them were not eating anything but the liver.
The other quarter were eating more liver than the others, and more than 90 percent of the animals were eating their liver for protein.
This shows that the amount they absorb is directly related to their level of toxicity, says Dr. Larkin.
The study found that birds who were eating the liver for meat and not for nutrition were significantly more toxic to their environment than those who ate liver for a protein-rich diet.
These birds were also consuming more arsenic, but only about half as much.
So the researchers say that the study does not show a correlation between the amount eaten of the liver and the level of arsenic it contained.
What does this mean for humans?
The study does suggest that it is very difficult to tell if you have liver toxicity, because in the past, liver was used as a marker for toxic substances.
This was because it contained arsenic and other toxic elements, so there were a lot of other compounds that could be found in the meat that could lead to liver toxicity.
For instance, liver may contain more toxins, or it may have a higher content of other substances that could also be toxic.
The team also said that the more animals that are eating their own liver, the more toxic their liver is.
And they found that this is true for both sexes.
In males, they found a higher level of liver toxicity in females than males, but the difference was only statistically significant for males.
It could be that this results from differences in the amount that males and females eat.
For example, in some of the females who were getting their liver from their own chickens, there were less of the enzymes that the other enzymes in the animals’ liver were using, and this could explain why the level was higher in females.
But Dr. Siegel says this is unlikely to be the case.
In females, there is more protein in their liver, so the amount absorbed by the liver might be more similar to that of the other parts of their body.
And the amount in the body of proteins is a function of the balance between amino acids and fat, which also contributes to the toxicity.
“When you’re feeding your chickens a high protein diet, you have to make sure that they’re getting all of the amino acids they need for their bodies, so if they are getting too much of one type of amino acid, that’s a problem,” he says.
“The other issue is that they are eating so much protein, which leads to excess protein and fat absorption.
That can be a problem, as well.
So, if you are feeding your birds a high-protein diet, they will be eating more of that protein than they need.”
Dr. Anthony O’Donoghue, the director of research at the National Chicken Council, says that it’s not possible to say how much arsenic a bird gets from its diet, but that the studies show that “there is a correlation”.
“It is important to note that it could be any number of different substances that
