Hormones para suprimir a fome nos bebês
Segunda-feira, abril 23o, 2007
As plantas para adicionar um hormone que suprima a fome ao alimento da fórmula do bebê são improváveis trabalhar peritos da palavra. Mas os peritos disseram que o trabalho detalhado no Chemistry e na indústria era “fiction de ciência descontroladamente optimistic” e leptin testando questionado em bebês. O fed dos bebês com fórmula cresce mais rapidamente do que bebês breast-fed - quem têm um risco mais baixo do obesity como adultos. `Que adiciona algo traseiro' O trabalho no efeito do leptin, um hormone produzido no cérebro durante todo a vida, está sendo realizado no laboratório de Clore na universidade de Buckingham. A equipe, conduzida pelo microfone Cawthorne do Dr., está olhando de adição o leptin ao leite da fórmula e aos outros alimentos. Têm realizado já um estudo onde o leptin fosse dado aos ratos grávidos, conduzindo a um impacto lifelong no propensity da sua prole ao obesity. Mesmo aqueles alimentaram uma dieta gordo-laden permanecida slim, quando a prole dos ratos untreated ganhos tornar mais pesado e desenvolveu o diabetes. A pesquisa no efeito do hormone sobre o apetite humano provou assim distante decepcionar, com os povos que parecem logo resistir seus efeitos fome-extinguindo. Mas o Dr. Cawthorne dito fornecendo o leptin cedo eficazmente “hard-wires o contrapeso de energia do corpo”. Adicionou: “Suplementado ordenha está adicionando simplesmente algo para trás que estava originalmente atual - o leite de peito contem o leptin e as alimentações da fórmula não.” `Que altera o cérebro' Entretanto, um número de peritos criticaram o conceito de adicionar o leptin ao leite da fórmula. Steve O' Rahilly, professor do biochemistry e da medicina clínicos na universidade de Cambridge disse: “Diversos investigadores sugeriram que expo animais a uns níveis mais elevados do leptin durante a vida adiantada pôde ter benefícios long-lasting nos termos da proteção de encontro a um obesity mais atrasado. “Mas isto necessita ainda ser firmado acima. “A noção que o leptin no leite do bebê impedirá o obesity humano está atualmente nos reinos do fiction de ciência descontroladamente optimistic.” O Dr. entalha um diretor mais fino, clínico da facilidade clínica da pesquisa de Wellcome no hospital de Addenbrookes, Cambridge, concordado. Disse: “The concept that adding something to a food that could permanently alter brain development is exciting but at the same time so scary that it would mean a wholly new approach about how such treatments can be tested and approved for use. “And would the first trials be in newly born children?” Dr Ian Campbell, honorary medical director of the charity Weight Concern said: “Without evidence that this works in humans, it is pure flight of fancy that those consuming leptin from infancy will never get fat. “I’d be surprised if this product could be advertised or marketed with these extraordinary claims.” He added: “To date, leptin has proved to be a great disappointment. Most of us have plenty, and true deficiencies are rare. “In fact, obese people tend to have higher than normal levels.” http://news.bbc.co.uk/1/hi/health/6575767.stm Have Your Say: Hormones To Suppress Hunger In Babies Please read our posting guidelines before posting.
