Vegan, but only part-time, fashion which is good for our health News

BE vegan , but only every so often. Eliminate meat, fish, dairy and eggs, but only a few days per month. Why you may be concerned about the environment and at the same time not forgo the steak and cheese. This is the thought at the basis of an experiment designed by the british magazine New Scientist, inspired by “Veganuary,” the campaign was founded in 2014 to inspire people to follow a diet 100% vegetable solely in the month of January, they asked: does it make sense, for the health and for the environment, be vegan, part-time?

To answer, the newspaper has invited 19 members of his editorial (13 omnivores, 3 pescetariani and 3 vegetarian) to follow a diet with no animal foods for a week. Excluded from the table not only meat and fish but also eggs, dairy products, honey. The participants noted the meals for two weeks (the first seven days followed their diet, the next vegan options), and the collected data were analyzed by a team of experts from the university of Oxford.

The first effect examined was that on health: the abandonment of animal foods has decreased the daily caloric intake, fat consumption, especially saturated, and of protein. on The other hand, has increased the intake of carbohydrates and fibre, with a slight decrease of calcium levels. "Even the ancient religions, like judaism and christianity, and the Catholic, when, obliged to abstain from meat consumption on Fridays and during the period of Lent, pushed for a period of "purification" – says Anna Maria Castellazzi, specialist in food Science at the University of Pavia – Without a doubt, this habit can have positive effects on health without affecting the levels of micro-nutrients and important vitamins, such as those of group B, and especially B12. A result which, however, can result in a diet that is strictly vegan".

MORE Vegan at all costs, which tripled in a year

Forget for seven days, meat, fish, eggs and dairy products would have positive outcomes on the environment: according to the data, in the week vegan greenhouse gas emissions associated with food choices of the participants have fallen by more than half. Shame about the small sample. "The scientific evidence is based on numbers – remember Anna Maria Castellazzi – and what happens to 19 people for a week of "treatment" has no scientific value, nor can it have a value on the state of health in the short and long term".

If some of the good habits (more fiber, less red meat and processed) persist after the return to the food regimen, original, dress shoes vegan for a limited period can be useful. However, concludes the expert, "the rule mother is always moderation, and then a varied diet that includes all foods, well distributed throughout the week. And the real solution to the containment of greenhouse gas emissions is to plant more trees, rather than push for a diet that remains unbalanced".
