Eating Turmeric Could Boost Your Memory And Mood

In the world of superfoods, turmeric is seemingly becoming more and more super by the day. A new study has found that the spice’s active ingredient could boost memory and mood.

The 18-month study — carried out by researchers at the University of California, Los Angeles (UCLA) and published in The American Journal of Geriatric Psychiatry — was the first long-term, double-blind, placebo-controlled trial of a bioavailable form of curcumin in non-demented adults. It found that taking a daily dose of curcumin, the compound in turmeric root that gives the spice its yellow color, may not only prevent memory problems from getting worse over time, but actually improve them.

Led by UCLA’s Gary Small, the research team took 40 random people between the ages of 50 and 90 suffering from mild memory problems but not Alzheimer’s disease or other form of dementia, gave them a twice-daily 90-mg of bioavailable, easily absorbed curcumin supplement or a placebo for 18 months, conducted tests of memory and cognition that included questionnaires to measure mood and depression, and carried out brain scans to analyse the deposition of “brain gunk”—amyloid-beta plaques and tau “tangles,” the two hallmarks of Alzheimer’s.

Because the study was double-blind, even the researchers didn’t know what supplement the participants were given until after the study was over.

They found that those who took the curcumin saw their memory improve by 28% on average over the 18 month trial, while those who took the placebo (the control group) saw their scores rise slightly (possibly because they got more familiar with the tests) and then declined.

The depression scores of those taking curcumin also improved compared to the control group’s, which stayed the same, and brain scans revealed significantly less amyloid and tau accumulation in two of their brain regions — the amygdala and hypothalamus — that control anxiety, memory, decision-making, and emotion.

This lead Small’s team to conclude that taking a bioavailable curcumin supplement daily may lead to improved memory and attention in non-demented adults, which according to Forbes is an exciting discovery considering that it came from a true clinical study and earlier evidence regarding the therapeutic effects of curcumin has been mixed.

Curcuma longa root - Turmeric

It’s not exactly known how curcumin works, but researchers have long observed that people in India have lower incidence of Alzheimer’s disease, which they think is due in part to the higher intake of turmeric. Small said in a statement:

“Exactly how curcumin exerts its effects is not certain, but it may be due to its ability to reduce brain inflammation, which has been linked to both Alzheimer’s disease and major depression.”

One shortcoming of the study is that it was quite small and the participants were generally healthy, educated, and motivated to complete the long trial, which may not necessarily be a complete reflection of the general population. The team’s next plans to look at whether the supplement may be effective in treating people with major depression rather than memory problems.

The growth of the “food as medicine” movement is evidence of consumers’s growing interest in natural ways to improve their health. And according to Food Dive, while medical foods are still a relatively new category in the food industry, manufacturers have been looking at ways to incorporate curcumin in the formulation of nutraceuticals, dietary supplements, herbals and functional foods and beverages, especially for those consumers who don’t want to cook with turmeric but want ready-to-eat options containing the ingredient.

Improve Your Gut Health By Eating Mangoes

Published

Fresh Mango

If you suffer from constipation, a mango might just be what the doctor ordered.

A new pilot study carried out by Texas A & M University and published in the the peer-reviewed journal Molecular Nutrition and Food Research found that mangoes contain a combination of polyphenols and fiber that is more effective than an equivalent amount of fiber powder in relieving constipation.

Susanne U. Mertens-Talcott, a corresponding author of the four-week study and an associate professor in the department of nutrition and food science at Texas A & M University, stated:

“Our findings suggest that mango offers an advantage over fiber supplements because of the bioactive polyphenols contained in mangos that helped reduce markers of inflammation and change the make-up of the microbiome, which includes trillions of bacteria and other microbes living in our digestive track. Fiber supplements and laxatives may aid in the treatment of constipation, but they may not fully address all symptoms, such as intestinal inflammation.”

Researchers took 36 adult men and women with chronic constipation and randomly divided them into two groups — a mango group that ate about 300 grams of mango a day (equivalent to about 2 cups or 1 mango) and a fiber group that incorporated the equivalent amount of fiber powder (1 teaspoon or 5 grams of dietary psyllium fiber supplement) into their daily diet.

A food questionnaire was then given to the participants to assess their food intake and ensure their eating habits remained consistent (i.e. equivalent amounts of calories, carbohydrates, fiber, protein and fat) and measures of constipation severity were taken at the beginning and end of four weeks.

Their analysis revealed that while both the mango and fiber groups improved over the course of the study, mangoes proved more effective in reducing the symptoms of constipation than fiber alone.

Mango supplementation significantly improved constipation status (e.g. stool frequency, consistency and shape), increased short chain fatty acids levels, which indicate improvement of intestinal microbial composition, and helped to reduce certain biomarkers of inflammation.

Mangoes have long been know to be a rich source of dietary fiber, but Texas A & M University’s study is possibly the only study ever to be dedicated to the efficacy of the tasty fruit at relieving constipation.

But as promising as these findings are, the researchers concluded that more research is needed to determine the exact mechanism behind the protective effect of mangoes in constipation and the role mango polyphenols may play in supporting the beneficial effects of fiber.

A mango day keeps your food moving smoothly and easily, right?

Shirataki Noodles Are Very Good For You In Many Ways

Published

on

Shirataki Noodles in wood bowl

What is satiating, gluten-free, fat-free, virtually carb- and calorie-free, and potentially delicious? Shirataki Noodles! Heard of them?

The thin, translucent, gelatinous Japanese noodles (also called miracle noodles, glucomannan noodles, konjac noodles, or konnyaku noodles) are becoming increasingly popular as a low-carb, ketogenic pasta replacement, so let’s have a look at just what makes them so miraculous.

For starters, they are made from the konjac yam (AKA devil’s tongue yam or elephant yam) that’s native to China’s Yunnan province and cultivated other regions in eastern Asia. They can be purchased wet (soft) or dried at Asian markets and some supermarkets.

The Good

Shirataki noodles are composed of 97% water, 3% fiber and traces of protein, fat, and calcium, meaning they have virtually no calories and carbohydrates.

More specifically, there are four calories and roughly only one gram of net carbs in every 100 g / 3.5 oz of shirataki noodles, which is astonishing for a plant-based food. Such a nutritional profile makes them perfect for any diet, especially a low ketogenic diet.

The reason why the packaging may say “zero” calories or “zero carbs” is because, at least in the United States, Canada and elsewhere in the world, products with less than five calories and/or less than 1 gram of carbs, protein and fat are allowed to to be labeled as zero.

Because Shirataki noodles are mostly water and fiber, they leave you feeling more satiated than comparable high-carb, low-fiber foods like pasta and less likely to reach for that bag of chips. Moreover, the noodles provide a unique type of fiber that is rarely found in western diets.

Replacing any high-carb food like pasta and rice with a virtually zero calorie and zero carb food like shirataki noodles could do wonders for your weight and overall health, manly because of the glucomannan they contain.

Studies have found that glucomannan, a soluble fiber that comprises 40% of the dry weight of the konjac plant, has many properties that are conducive to weight-loss and better cardiovascular health. In addition to promoting satiety by keeping you fuller for longer and with less food, it has a number of other benefits:

Shirataki noodles are truly miraculous, and you have little to lose by including them in your diet. However, there are a few potential drawbacks that you should be aware of.

The “Bad”

Shirataki noodles have very little micronutrients, and as beneficial as glucomannan may be, it expands rapidly and can absorb up to 50 times its weight in water, so much water, in fact, that emptying a single glucomannan capsule into a small glass of water turn the entire thing into gel. This helps trigger satiety, but it can also cause discomfort.

If glucomannan expands before reaching the stomach, it may cause choking or blockage of the throat and esophagus. But this is an issue that can be prevented by washing it down with 1-2 glasses of water or other liquid.

Glucomannan has also been found to cause bloating, flatulence, and soft stools or diarrhea. It can potentially reduce the bioavailability of oral medications and supplements; if that happens to you, try taking your medication at least 4 hours after or one hour before consuming it.

It is important to note, however, that all of these side effects stem from glucomannan itself and not Shirataki noodles. The fact that the noodles are usually saturated with water and sauce when eaten means you probably won’t experience any of these side-effects.

The Verdict

There has been an outpouring of research showning that Shirataki Noodles are an excellent addition to any weight-loss diet, thanks mostly to the glucomannan they contain. Glucomannan is gluten-free, and as a soluble fiber, absorbs water in the stomach to make you feel fuller for longer.

Glucomannan is an effective weight-loss supplement, and Shirataki Noodles are versatile, keto-friendly and gluten-free alternative to regular noodles, spaghetti and pasta, rice and any other staple rich in carbs, starch and calories. However, as with just about every weight-loss strategy, neither works in isolation. For you to achieve lasting results, you need to make a permanent change to your lifestyle.

Are you up for the challenge?

10 Signs You Are Allergic To Gluten

Published

on

Long Bread

Intolerance to gluten has been a running buzz in the healthy living circles for the past decade, and there is no sign of that changing. The condition can lead to detrimental health effects relating to the gut, skin and even nervous system, with the most common symptoms being depression, fatigue, gastrointestinal problems and pain.

Gluten is a protein found in such grains as wheat, rye, barley, spelt and is what makes bread light and fluffy and dough a sticky texture. Wheat and rye are most commonly found in cereal and bread, as well as in pasta in the case of the former and even beer, salad dressings and soups with the latter. Barley is often used in stock feed products.

Not only do all of these grains contain gluten, but they can also cause insensitivity to gluten. Unfortunately, they are a common part of the diets of millions, if not billions, of people around the world.

Gluten intolerance has also been associated with celiac disease, an autoimmune disorder that can cause damage to the small intestine, making it harder for the body to absorb nutrients. Around 1 out of 100 people suffer from the condition in the United States alone!

Fortunately, symptoms of gluten intolerance subside after removing gluten from one’s diet. Here are 10 of the most usual signs that you may be suffering from it:

1. Unexpected Weight Gain

Caused by malabsorption and gut permeability from the systemic inflammation triggered by the protein, unexpected weight gain is related to gluten intolerance. Sufferers who eliminate gluten from their diet will notice an improvement in their weight.

2. Brain Fog

In an article published in the Journal of Neurology, Neurosurgery and Psychiatry, one titled “Gluten sensitivity as a neurological illness,” researchers found that immunoglobins (AKA antibodies) react abnormally to gluten and the reaction contributes to reduced cognitive function.

3. Abnormal Immune function

The IgA antibodies, which are found in the gastrointestinal tract and saliva, are the body’s primary response to colds, flu or other illnesses. If you are gluten sensitive, these antibodies have a counter effect on your immune system, inhibiting its ability to properly defend against such illnesses.

4. Headaches, Migraines

A recent study discovered that 56 percent of the gluten intolerant participants suffered from migraines, while only 14% of the control group had the condition.

5. Dental Issues

A study published in the BMS Gastroenterology found that there is a connection between gluten intolerance and “aphthous stomatitis”, a condition characterized by the repeated formation of mouth ulcers and canker sores in otherwise healthy individuals. Malabsorption can cause gluten intolerant people to also have low calcium levels, which undermines oral health.

6. Skin Problems

Malabsorption resulting from gluten intolerance has been associated with eczema, acne and dermatitis herpetiformis (DH), with symptoms including redness, itching, rashes, burning and blisters. Described by the Gluten Intolerance Group as “a chronic disease of the skin marked by groups of watery, itchy blisters that might resemble pimples or blisters,” DH is a very difficult condition to have.

7. Joint And Muscle Aches

Researchers have long known that people with autoimmune forms of arthritis are at higher risk for celiac disease, and a growing body of research now finds that here is a possible connection between gluten and non-pathologic joint pain. When a person with celiac disease or a gluten sensitivity eats gluten, the immune system jumps into action, causing inflammation.

8. Fatigue And Exhaustion

This symptom is similar to brain fog in that the mechanism involved are still a mystery. There is little scientific research on the the purported correlation between fatigue/exhaustion and gluten intolerance; however, the fact that fatigue is one of the most frequent symptoms mentioned by those with celiac or gluten sensitivity has led medical experts believe gluten intolerance can cause fatigue and exhaustion through inflammation likely because of de-allocation of the energy reserves.

9. Hormone Imbalances

Gluten is a known to disrupt a number of hormones, including estrogen, and has been linked to Polycystic ovary syndrome (PCOS), abnormal PMS, and unexplained infertility. According a article published by the Gluten Free Society, the removal of gluten often resolves hormone imbalance.

10. Anxiety, Depression, ADD, Mood Swings

Depression and anxiety symptoms have been linked to gluten consumption in celiac sufferers, while one small study found that excess gluten possibly depleted the serotonin levels of non-celiac suffers, leading to feelings of depression.
