Ever notice how you’re still hungry after eating fast food? Here’s why: Your brain detects the nutri
(Natural News) There’s no denying the appeal of fast food. Who hasn’t felt the pull of a juicy burger at the end of a long and exhausting work day? And yet, eating that burger often leaves us feeling bloated, heavy and strangely unsatisfied. A groundbreaking new study by researchers from the University of Warwick in the United Kingdom may finally have unlocked the reason why certain meals, no matter how large, leave us feeling unsatisfied, while other, smaller meals keep us full for ages.
Science Daily recently reported that the research team, led by Professor Nicholas Dale of the University’s School of Life Sciences, has discovered that cells called tanycytes, which are found in the brain and control energy levels, detect specific nutrients in the foods we eat mere seconds after we eat them. The study will be published in the journal Molecular Metabolism.
Tanycytes respond to the amino acids found in foods using the same receptors on the tongue that detect flavor, and when they react with two of these amino acids – arginine and lysine – they send messages of fullness and satiety to the brain.
Arginine and lysine are particularly prevalent in certain foods, including: almonds, cheese, chicken, tuna, sesame seeds, anchovies, apricots, aubergines, crab, dates, figs, lentils, turkey, peanuts, pistachios, plums, pork shoulder, sweet potatoes, tahini and walnuts.
Whole foods that are high in protein, in other words. (Related: Clean eating now considered a “dangerous fad” by nutritionally illiterate doctors.)
The research team conducted their investigation by adding concentrated amounts of these two amino acids directly into brain cells. Since the cells were made fluorescent, even microscopic changes or reactions would be visible to the scientists. Within 30 seconds, the team observed the tanycytes reacting to the lysine and arginine, sending messages to the part of the brain that controls appetite and weight.

“Amino acid levels in blood and brain following a meal are a very important signal that imparts the sensation of feeling full,” Professor Dale explained. “Finding that tanycytes, located at the centre of the brain region that controls body weight, directly sense amino acids has very significant implications for coming up with new ways to help people to control their body weight within healthy bounds.”....more here
