Do you like your meat or do you prefer vegetables? In our family, it's a bit of both. My hubby and my step-daughter love red meat, I do too but can do without, as I am happy with a plate of couscous or lentils, Imo has just become a vegan after being a vegetarian since she was 13! What about you? What's your diet like? I must say that I will avoid talking about deserts!..
Is this new research I found in the daily telegraph a publicity stunt?
The researchers define a “high-protein” diet as deriving at least 20 per cent of daily calories from protein. They recommend consuming about 0.8g (0.03oz) of protein per kilogram of body weight every day in middle age. It means a person weighing nine stone should eat about 45-50g (1.6-1.7oz) of protein a day. A 300g (10.5oz) steak contains 77g (2.7oz) of protein.
As well as red meat, dairy products high in protein are also dangerous, the researchers said. A 200ml (7fl oz) glass of milk represents 12 per cent of the recommended daily allowance, while a 40g (1.4oz) slice of cheese contains 20 per cent.
Chicken, fish, pulses, vegetables, nuts and grain are healthier sources of protein. However, a chicken breast or salmon fillet still accounts for about 40 per cent of recommended daily protein intake.
“The research shows that a low-protein diet in middle age is useful for preventing cancer and overall mortality,” said Dr Eileen Crimmins, a co-author of the study.
“However, we also propose that at older ages, it may be important to avoid a low-protein diet to allow the maintenance of healthy weight and protection from frailty.”
British experts agreed that cutting down on red meat had been proven to lower the risk of cancer but said a balanced diet was still the best option.
Dr Gunter Kuhnle, a food nutrition scientist at the University of Reading, said: “While this study raises some interesting perspectives on links between protein intake and mortality… It is wrong, and potentially even dangerous, to compare the effects of smoking with the effect of meat and cheese.”
He claimed that sending out such statements “can damage the effectiveness of important public health messages”, adding: “The smoker thinks: 'why bother quitting smoking if my cheese and ham sandwich is just as bad for me?’ ”
Prof Naveed Saattar, an expert in metabolic medicine at Glasgow University, said the low-protein effect in older people could be due to “survival bias”, where those who have lived longer are already generally healthier.
Protein controls the growth hormone IGF-I, which helps bodies grow but has been linked to cancer susceptibility. Prof Tim Key, a Cancer Research UK epidemiologist, said: “Further research is needed to establish whether there is any link between eating a high protein diet and an increased risk of middle aged people dying from cancer.”
