Debunking Common Nutrition Myths


The best factor regarding being a nutritionist is talking regarding food with individuals from all completely different backgrounds as they parade in and out of my workplace. additionally to giving Pine Tree State a glimpse into their uptake habits, my patients share their guiding beliefs regarding food and nutrition, assembled from a patchwork of sources: friends, family, magazines, the net, and well-liked mental object.

As it seems, several of those guiding beliefs are literally quite misguided. So, i am setting the record straight on 5 of the foremost common, persistent, and inaccurate nutrition myths I frequently encounter.

1. Bananas aren't "constipating."

The idea that bananas square measure costive doubtless derives from the observation that bananas will facilitate fix up the stool once one has looseness of the bowels. however bananas don't work their magic by inflicting constipation. Rather, bananas—particularly the less-ripe ones—are comparatively low in fiber and comparatively high in a very hard-to-digest starch referred to as "resistant starch." this mixture appears to contribute to their ascertained benefits; not an excessive amount of of the fibrous, idigestible material that might build looseness of the bowels worse, however rather an honest dose of gummy-textured starch that holds its type well within the colon and may take in some excess fluid. A food that's really costive would got to truly prevent the contractions of one's intestine, that bananas most actually don't do. My best guess on why individuals swear that eliminating bananas helps them head to the lavatory might got to do with what is exchange those bananas within the diet. A higher-fiber fruit, perhaps?

2. sugar isn't healthier than white sugar.

While brown (whole-wheat) bread is so healthier than bread, and rice is additional alimentary than rice, this parallel doesn't hold true once scrutiny sugar (a.k.a. "Sugar within the Raw," or raw turbinado sugar) to white sugar. whereas promoting would lead you to believe that this sugar is somehow "more natural," it's most actually no healthier. Raw sugar has even as several calories per teaspoon as additional refined white sugar, and your body actually cannot tell the distinction once it involves metabolism. Defenders would possibly argue that sugar has additional vitamins and minerals than the white stuff, to that my response is: If you are uptake enough raw sugar that it's serving as a measurable supply of vitamins or minerals in your diet, you must build {an appointment|a Pine Tree Stateeting|an arrangement|a briefing|a rendezvous} to return see me.

3. Enzymes in raw fruits or vegetables don't assist you digest them higher than cooked  vegetables.

As a matter of truth, cooked  vegetables tend to be additional simply digestible than raw ones! Enzymes square measure revered as sorcerous and all-powerful forces of digestion among nutrition enthusiasts. whereas I share nice awe for the alchemy that takes place on the digestive tube, let's be clear regarding what enzymes square measure and the way they work. Simply, enzymes square measure proteins whose specific shapes and configurations modify them to finish chemical reactions, like those required to interrupt down food. Our bodies secrete various completely different organic process enzymes, beginning within the secretion, moving to the abdomen, then from the exocrine gland to the liner of the tiny gut. every catalyst is activated beneath terribly specific conditions. For AN catalyst to become active, the hydrogen ion concentration level (or, the correct level of acidity) has got to be good, and in some cases, alternative compounds, referred to as co-factors, have to be compelled to be gift so as to modify them on. This constellation of circumstances is regular dead to coincide as food makes its method through the alimentary tract. A healthy, well-functioning body produces all of the enzymes it must absolutely digest all dietary parts except fiber (which, by definition, is inedible to humans). Any animal or vegetable enzymes gift in our food square measure neither needed for—nor enhance—human digestion. moreover, any such enzymes we tend to consume with our food can doubtless face an equivalent fate as alternative dietary proteins they have been eaten  with: they will be digestible. What regarding supplemental organic process enzymes, like Beano? These might so facilitate break down inedible plant fibers that humans lack acceptable enzymes. however these enzymes square measure derived from yeast, not raw veggies or fruit.

4. you'll eat insane, seeds, and popcorn if you've got pathology.

Diverticulosis may be a condition within which tiny pouches develop on the colon. In ten p.c or additional of cases, these pouches will become infected, inflicting a painful condition referred to as inflammation. historically, doctors and grandmothers have cautioned pathology patients to avoid foods like popcorn, nuts, and seeds, beneath the principle that robust, inedible particles from these foods would possibly "get stuck" {in a|during a|in AN exceedingly|in a very} pouch and cause an infection. Alas, actual analysis has didn't validate this hypothesis time and time once more, although innumerous individuals still avoid these glorious sources of fiber. Since higher dietary fiber intake has been joined to the interference of complications among those with pathology, this can be one nutrition story that ought to be ordered to rest, once and for all.

5. milk sugar from a nursing mother's diet doesn't build nursed babies flatulent.

Unless a baby is born with a rare upset, all babies square measure ready to digest milk sugar, the first sugar in milk. even though a nursing mother ne'er grub a drop of dairy farm in her life, forty p.c of the calories from her breast milk can still derive from milk sugar. milk sugar from a mom's diet is weakened into its element sugars—glucose and galactose—in her intestines before it is absorbed into her blood. Once these parts square measure absorbed, they are doing not reassemble; in alternative words, intact dietary milk sugar ne'er travels through the blood specified it may build it into a woman's breast milk. Rather, the milk sugar in breast milk is factory-made from scratch "on location," within the cells of exocrine gland glands. Therefore, if you have a flatulent baby, adopting a lactose-free diet are going to be of fully no profit.
