Popeye tricked us: spinach has no more iron than lettuce. Two Foods Yes

<p>False. This myth means breaking an icon of our childhood. Like knowing who the Magi were, seeing Leticia Sabater at the Alaska Circus, or knowing that Xuxa was an actress in erotic films before she was the Queen of children's programs. Actually <strong>the spinach that was taken Popeye before stoking Brutus do not have as much iron as was thought</strong> and, moreover, having much fiber and molecules like oxalic acid (yes, the stones in the kidney) that kidnap the iron, its absorption is quite poor. All these factors incite to think that Popeye spinach should carry some added product that would give positive in an anti-doping control.</p> <p>What is the origin of the myth of Popeye, spinach and iron? Elsie Segar created her Popeye character in 1929. At that time we had just discovered the important role that iron had in nutrition and the relationship between lack of iron and anemia, so an iron supplement could be the key to recovering lost strength. The mistake was to think that the more iron, more force, justified error if we think that in the year 1929, with <em></em> the crash of the stock market, in the United States there were large pockets of poverty and starved, so the anemias were frequent.</p> <p>At that time, in the tables of the iron content of the different foods, the spinach were placed at the top, but by a mistake. Measures of the amount of iron in food began to take place at the end of the nineteenth century using a chemical reaction with a compound called "thiocyanate". <strong>the first to measure the iron content of the spinach was the German chemist Erich von Wolf in 1870 and was mistaken putting the coma</strong>: What were 0.35 milligrams per 100 grams ended up being 3.5 milligrams per 100 grams, ie ten times. Also, to assimilate iron you need vitamin C, so not only do we have to take into account the iron content, but with what we eat it.</p> <p>The reality is that spinach is a very bad source of iron [even the lettuce has more: 0.4 milligrams for every 100 grams]. <strong>iron-rich foods are liver meat, clams, or beer yeast</strong>. There are iron-rich legumes such as beans or chickpeas, although their absorption is not so good because of the fiber they contain. Therefore, you need iron, but to have the muscles of Popeye, the gym better (although I suspect his spinach carried anabolics, sure Popeye was cycling).</p> <div class="sumario__interior"> <header class="sumario-encabezado"> <h4 class="sumario-titulo">' What is healthy eating?
