Junk diet is `like a narcotic'

All that was apparently shown here is that rats got to like human foods and acted disturbed when given only rat pellets again. If someone fed me rat pellets instead of my normal diet, I would get pretty disturbed too. It undoubtedly shows that rat pellets are unappetizing but what else it proves I fail to see

PEOPLE who eat too much junk food can become addicted to it in the same way a drug-user becomes dependent on narcotics, ne research shows. Researchers at the Sansom Institute in South Australia have found that excessive consumption of foods high in fat and sugar triggers the release of dopamine in the central reward pathwav in the brain.

"This creates a feeling of pleasure not dissimilar to that caused by drugs of abuse," lead researcher Zhi Yi Ong said. "Repeated activation of the dopaminergic reward pathway is associated with the development of addiction."

Ms Ong and her team used rodents to explore junk food dependence feeding them biscuits, Nutella, peanut butter, Froot Loops and Cheetos for two months.

"Their desire for junk food ended up over-riding their physiological hunger signals," she said. The rodents also displayed anxiety when the researchers replaced their junk food with standard food. "The ability of chronic junk food intake to produce junk food dependence may explain why many individuals struggle to control their desire for these foods," she said.

Bubs'IQ plummet from lack of iodine

IODINE deficiency among pregnant women has reached such alarming levels. they will produce a generation of dumber children. a leading expert warns. Endocrinologist Professor Creswell Eastman has just completed a study of 400 pregnant women at Sydney's Westmead Hospital and found 60-70 per cent of them were iodine-deficient - up from 50 per cent a few years ago.

Iodine is a trace element essential for brain growth in a developing foetus and to maintain normal thyroid function, growth and metabolism.

Professor Creswell, vice-chair of the International Council for Control of Iodine Deficiency Disorders, said women involved in the study were only getting half the iodine they required. "Children born to mothers who are moderately iodine-deficient have lower IQs ... It is dumbing down our population," Prof Eastman said. "We could solve the whole problem if we could convince the Government that all salt for human consumption should be iodised," Prof Eastman said.

Table salt IS already all iodized as far as I know. Salt used in food manufacture probably is not however. So it is the health nuts warning people off adding salt to their food who are causing this problem

"Table salt IS already all iodized as far as I know."

It is the law in the US, not sure of the UK - probably. Done to assure widespread iodine intake, especially in areas not near oceans (sea breezes, "salt air," carry a tiny but important trace as do oceanside area plants and [thus] animals), over a half-century ago.

When thyroid problems skyrocket - especially among children as that is the easiest place for the governments to ban table and cooking salt, how will they deliver the iodine? Sprinkle crystallized iodine in front of all those windmills dotting the countryside?

Rat pellets? That's testing milk lacking serial on a scavenger species with a truly primitive mammalian brain. Now dogs eat most anything so they get lots of table scraps and they chew of dried pig ears that are for sale like candy at every pet store. But test CAT PELLETS, namely the top of the line Science Diet brand. I did. I went to Costco and got bulk tuna in water. Despite the urban myth level reputation of bulk tuna as being swampy, it in fact is much fresher than grocery store cans of the same Chicken of the Sea brand. Why? Because in a big can you can fit REAL chunks of animal meat. It NEVER starts to smell after even a week in a refrigerator. And guess what? My cat now SNACKS on dry serial but eats his real meals as real meat. What is in Science Diet? Chicken junk (fat and "by-product"), GRAIN and LIVER FLAVOR and...VITAMINS. They even add Vitamin C. Only humans lack the ability to make Vitamin C! Cats don't need vitamins! They need meat. And even my cat will happily survive on dry food for a week if it rains that week so I can take a folding motor scooter to Costco from Manhattan. Why? Since he knows he'll eventually get tuna, the only other food he will eat. And he's part Asian Leopard Cat, being a Bengal. Might such higher organisms, especially Man, have much less Skinner box lack of perspective than a literally caged rat to whom survival level emotions are about as deep as their brains can reach even while running around in the basements and alleyways of my urban city? There are cats here too, smartly hanging out in various parks, eating the rats that stray too far from civilization. Though not friendly, they sure are healthy, along with the raccoons of Central Park. What do food pellets have to do with ANYTHING in a human's life, in this perspective?
