Unrealistic Expectations for Gluten-Free Diets?

Unrealistic Expectations for Gluten-Free Diets?

breadIt is official: the gluten-free diet is the latest “magic bullet” weight-loss craze. Seeing shelf after shelf filled with gluten-free foods in grocery stores is becoming the new norm, which is great news for the relatively small number of people who truly suffer from gluten-intolerance (aka celiac disease). But gluten-free has become something much larger—the nation’s newest weight-loss love affair. However, evidence suggests that a gluten-free diet by itself is largely useless if you’re trying to lose weight. So, this begs the question—do Americans now have unrealistic expectations when it comes to living gluten-free?

In a word, yes. According to the Wall Street Journal, about a third of the American populace is avoiding gluten, a protein that is responsible for the elastic texture of dough that is often found in grains such as wheat. While about 1% of the population suffers from celiac disease, sales of foods labelled “gluten-free” have exploded and are now worth an estimated $23 billion per year. Many people take up this diet with expectations of losing weight—but they may find themselves disappointed.

As US Newsreports, “But there’s no hard evidence that a gluten-free diet is appropriate for weight loss or is any more effective at whittling waistlines than other diet plans. Most experts recommend it only for those with celiac disease or gluten intolerance, says David Katz, founding director of the Yale-Griffin Prevention Research Center.”

However, the article goes on to say, “Still, cutting out gluten can lead to weight loss, since the plan forces dieters to shun high-calorie refined carbohydrates. ‘Tell anyone to cut down on bread and pasta, and they’re likely going to drop calories and lose weight,’ Politi [Elisabetta Politi, nutrition director at the Duke Diet and Fitness Center in Durham, N.C]says. But gluten-free is no weight-loss panacea, either. ‘If you’re going down the grocery aisle grabbing gluten-free cookies and pasta and bread, you probably won’t be as successful.’ A gluten-free brownie is still a brownie. Often, these products are packed with saturated fat, cholesterol, and sugar to improve taste.”

Not only are many gluten-free products packed with unhealthful ingredients, they are often more expensive than their gluten-containing counterparts—sometimes much more. This puts the gluten-free diet in the same category as other expensive fad diets that have given false hope to their followers. Instead, nutritionists agree, it is far better to live on a low-sugar diet that’s packed with fresh fruits and vegetables, whole grains, lean meat, and low-fat dairy.

As WebMD puts it, “Gluten itself doesn’t offer special nutritional benefits. But the many whole grains that contain gluten do. They’re rich in an array of vitamins and minerals, such as B vitamins and iron, as well as fiber. Studies show that whole grain foods, as part of a healthy diet, may help lower risk of heart disease, type-2 diabetes, and some forms of cancer. The 2010 Dietary Guidelines for Americans recommends that half of all carbohydrates in the diet come from whole grain products.”

So unless you suffer from celiac disease or non-celiac gluten sensitivity, you may consider saving your money and lowering your expectations for gluten-free. It’s been said before and it’ll be said again: there is no magic weight-loss bullet—at least not yet—and if you truly want to live a healthy lifestyle, proper diet and exercise is still the best way to go.

 

Children and Caffeine: What Parents Should Know

Children and Caffeine: What Parents Should Know

girlThe next time you pass a Starbucks, pause for a moment and imagine that the customers inside drinking their lattes and Grande Espressos are your children. Then imagine them ingesting a drug (caffeine) that is known as a powerful stimulant with a proven history of producing nervousness, restlessness, irritability, high blood pressure, insomnia, headaches and heart palpitations. Finally, consider that this exercise in imagination may not be all that far off the mark.

That is the key finding of the Centers for Disease Control and Prevention (CDC) in a 2014 study published in the journal Pediatrics. The researchers found that nearly three out of four children and young adults in America (73%) consume some caffeine a day, mostly from soda, tea, and coffee, but also from an alarming number of “energy drinks.”

This study comes as part of an investigation undertaken by the U.S. Food and Drug Administration (FDA) into the safety of foods and drinks that contain caffeine—especially their effects on children and teens. In response to numerous reports of hospitalizations and even deaths after the consumption of highly caffeinated drinks or “energy shots,” the investigators analyzed health surveys containing data on over 22,000 subjects aged 2 to 22.

Many foods contain caffeine (including chocolate, candy bars, some jelly beans, and marshmallows), but most of the caffeine ingested by small children comes in the form of soda. The rise in the use of energy drinks—although they account for only 6% to 10% of children’s daily caffeine intake—is seen as particularly alarming, because many of these drinks contain even higher amounts of caffeine than soda.

The FDA study found that the average caffeine intake among participants was about 60-70 milligrams—roughly the same amount of caffeine present in a six-ounce cup of coffee or two sodas. However, this finding does not necessarily mean that this level of caffeine consumption is safe for children. In fact, while the FDA has classified caffeine as GRAS (generally recognized as safe), that classification is based solely on its use by adults. There is actually no current body of research analyzing its possible detrimental effects on children. Nakia V. Williams, M.D., a pediatrician at the Henry Ford Health System, says, “There haven’t been a lot of studies of caffeine in young children, but we do know that children suffer from similar side effects as adults, and that on average these side effects can occur at lower doses given the smaller body sizes.” The American Academy of Pediatrics (AAP) recommends against caffeine consumption for children and teens because of possible harmful stimulant effects as well as the possibility of it worsening anxiety in children already suffering from anxiety disorders. The AAP holds the clear position that “stimulant-containing energy drinks have no place in the diets of children and adolescents.”

So if you have kids, think twice before allowing them to consume soda and other drinks that contain caffeine. Pediatricians are unanimous in suggesting that they would be better off drinking water, reasonable amounts of fruit juices, milk, and other non-caffeinated beverages.

Food as Medicine: Close-Up on Cumin

Food as Medicine: Close-Up on Cumin

??????????????????If “having a pedigree” is an important factor for you when you’re considering the nutritional or medicinal value of food, it’s difficult to find a food with a longer history than cumin. Cumin (also known as comino, cuminum cyminum, cuminum odorum, jeeraka, svetajiraka, and zira) is an herb whose medicinal qualities are mentioned in the Bible (both Old and New Testaments). Cumin was also part of the medical tradition in ancient Egypt, in India (cumin is a staple of Ayurvedic medicine), in the Muslim world, and in ancient Greece.

Although cumin is commonly used in the preparation of foods from each of these areas, it has also been promoted for its medicinal uses—to treat digestive problems, diarrhea, colic, bloating (cumin is a mild diuretic), to reduce inflammation, and even as an aphrodisiac. In terms of modern research, cumin has been found to have strong antioxidant and antimicrobial properties, and a study in the Journal of Ethnopharmacology found that cumin seeds help to regulate blood sugar levels, and thus may be of use not only as an antidiabetic (to prevent diabetes) but to treat those who already have the disease. Similar studies in Nutrition Research found that cumin not only helped to reduce hypoglycemia, but also to reduce body weight.

Cumin is also a known carminative, meaning that it has the ability to reduce the formation of gas and thus improve digestion. This is why it is common in Ayurvedic medicine, where it is both prescribed as a remedy for gas and used in cooking to reduce the flatulence caused by bean-based dishes. Cumin does have some analgesic (pain relieving) qualities, and is used as a tea in some cultures to treat headaches and other minor pains. Some have even recommended the combination of pureed bananas and cumin as a treatment for insomnia.

Today scientists theorize that one of the reasons cumin may have some curative properties is that it contains thymoquinone, a phytochemical also known as TQ that is being studied as a potential treatment for many diseases, including cancer. A 2005 study from India found that black cumin oil was effective in killing 50 out of 54 bacterial strains they tested—despite the fact that these same strains showed evidence of having developed resistance to 20 common antibiotics. In India, black cumin seed has also been proven effective in preventing withdrawal symptoms in patients with opium addiction. Research is currently underway to test the effectiveness of black cumin seed in reducing oxidative stress in the blood, lowering cholesterol, preventing and treating cancers and some forms of seizure, and treating rheumatoid arthritis.

Given all the interest in cumin and its potential health benefits, it’s reasonable to ask whether there might be risks associated with it as well. So far, there doesn’t appear to be a “down side” to adding more cumin to your diet. No serious contraindications have been noted in the medical literature, with one possible exception—you might want to check with your doctor if you are taking certain classes of anti-diabetic medications.

So not only can cumin bring an exotic taste to many of your more common recipes, it may also offer some health benefits along the way!

Fruit Juice and Kids: A Reality Check for Parents

Fruit Juice and Kids: A Reality Check for Parents

?????????????Ah, the simple joys of parenting! You want to do your best to give your kids a healthy diet, so after reading all the articles about how bad soda is for them, you switch them over to fruit juice. But now when you pick up a newspaper or read posts on your favorite Internet forum, you see more and more evidence that fruit juice may also be bad for them. What’s a parent to do?

The two-part answer to this question seems to be, “Get all the facts and use your best judgment. And—when in doubt—use moderation.” Yes, there is a new study, published in The Lancet Diabetes & Endocrinology, that calls for the UK government to change its “five servings a day” guidelines to exclude fruit juice. And yes, the researchers have their reasons for presenting this argument.

Those reasons seem to relate primarily to the amount of sugar in fruit juices. The study authors argue that a common misperception among parents is that fruit juices provide a natural, low-sugar alternative to artificially-sweetened drinks like soda. Technically, this is not true. As Naveed Sattar, professor of Metabolic Medicine at the Institute of Cardiovascular and Medical Sciences at the University of Glasgow in Scotland points out, “Fruit juice has a similar energy density and sugar content to other sugary drinks, for example: 250 milliliters (ml) of apple juice typically contains 110 kilocalories (kcal) and 26 grams (g) of sugar; and 250 ml of cola typically contains 105 kcal and 26.5 g of sugar.”

Professor Nattar’s research leads him to believe that—unlike consumption of solid fruit, which has been shown to decrease the risk of diabetes—high consumption of fruit juices is linked to an increased risk of diabetes. “One glass of fruit juice contains substantially more sugar than one piece of fruit; in addition, much of the goodness in fruit – fiber, for example – is not found in fruit juice, or is there in far smaller amounts,” Nattar’s research partner, Dr. Jason Gill, adds that although fruit juices do contain minerals and vitamins not present in sodas, the level of these nutrients is not sufficient to offset the health risks associated with consuming excessive sugar.

That’s the bad news. The better news is that even Drs. Nattar and Gill don’t recommend that parents cut fruit juice out of their children’s diet entirely, merely that they limit consumption to 1 to 1½ small (125 milliliter) glasses of fruit juice per day. The Australian Dietary Guidelines (ADG) released in February agree with them, still recommending fruit juice as part of a healthy, balanced diet for everyone, including children. They point out that one of the elements left out of the debate is that 100% fruit juice contains no added sugars, and often contain nutrients that sodas do not, such as vitamin C, folate, potassium and other micronutrients, plus antioxidants. Nutritionist Kristin Beck of the ADG says, “It’s not always possible for kids to get their recommended daily servings of fruit, so parents should be aware that 100% fruit juice can help meet these targets – especially for fussy eaters.”

Ms. Beck also provides what may be the best advice on the topic for parents: “Check the label to ensure you’re buying a good quality, 100% fruit juice. Be mindful of portion sizes and combine with a healthy, balanced diet that includes all core food groups – such as fresh fruit and veggies and a combination of lean meats, fish, dairy and carbohydrate-rich foods, mainly whole grains.”

The Power of Proper Nutrition: For the Mediterranean Diet, the Jury is In!

The Power of Proper Nutrition: For the Mediterranean Diet, the Jury is In!

andalusian paella close upAlthough the health benefits of the Mediterranean diet have been supported by anecdotal evidence and have been touted for years by health gurus and even a large number of doctors, it is only recently that the science to back up these claims has emerged. Researchers from the University of Barcelona performed a large-scale 5-year study that found that those who follow a Mediterranean diet can reduce their risk of death from the effects of cardiovascular disease, such as heart attack and stroke, by 30 percent.

The study, published in the New England Journal of Medicine, followed 7,447 people who had been selected to participate due to significant cardiovascular risk factors, including high blood pressure, diabetes, smoking, high cholesterol, a family history of heart disease and being overweight. The participants were randomly assigned to one of three groups:

  • A standard Mediterranean diet, supplemented with at least 4 tablespoons of olive oil per day
  • A standard Mediterranean diet supplemented with about an ounce per day of nuts (walnuts, almonds and hazelnuts)
  • A low-fat diet group.

Participants in the Mediterranean diet group consumed two servings of vegetables and three servings of fruit daily. They were to add fish and legumes to the menu at least three times a week and were asked to substitute white meat for red. If the participants drank alcohol, they were advised to drink a minimum of seven glasses of wine per week with their meals. Participants in this group were asked to reduce the amount of commercially baked goods they consumed to no more than three times a week, and to limit processed meats and dairy products.

Participants in the low-fat diet group were to avoid eating nuts and any type of vegetable oil (olive oil included), cut off visible fat from meat and limit store-bought desserts to less than once a week. They were asked to eat three or fewer servings daily of a simple carbohydrate such as bread, potatoes, pasta or rice, and consume three servings of low-fat dairy products, as well as fruits and vegetables.

No calorie limits were placed on any of the groups, nor were they encouraged to increase their level of physical activity. Those in the low-fat group had the most difficult time adhering to the dietary guidelines and most participants reverted to a standard Western diet, with a slightly lower fat intake.

Those assigned to the Mediterranean diets were found to be not only 30% less likely to have suffered a stroke, heart attack, or died during the study, they were also 40% less likely to have suffered a stroke in the study’s 4-year follow-up period than those who were assigned the low-fat diet. The aim of the study was not to reduce the participants’ cholesterol, blood pressure or weight, but to count the number of heart attacks, strokes and deaths from any cause to evaluate how effective the Mediterranean diet was in reducing these events and increasing longevity.

Not only have low-fat diets been shown to not be of much benefit, but they are known to be difficult to maintain because they leave people feeling unsatisfied. Dr. Steven E. Nissen, from the Cleveland Clinic’s department of cardiovascular medicine said “Now along comes this group and does a gigantic study in Spain that says you can eat a nicely balanced diet with fruits and vegetables and olive oil and lower heart disease by 30 percent,” he said. “And you can actually enjoy life.”

Why Sugar is So Hard to Resist

Why Sugar is So Hard to Resist

????????????????Sugar is in almost everything we eat. In the typical western diet, enough sugar has been added to food products to bring our consumption of the sweet stuff up to 22.7 teaspoons per day. It is added to processed foods to extend shelf life and enhance flavor and texture. While we know that sugar contributes to weight gain, diabetes and heart disease, it’s still hard to resist. Why? Much of the answer to that question has to do with the way humans have evolved to survive in times of scarcity.

Our ancestors who had developed a taste for sugar were able to add to their body fat, which helped to keep them alive during periods of famine. This in turn allowed them to pass their sweet-loving genes on to their progeny. A study conducted by researchers at Washington University found that we are programmed from birth to crave sweet things. Human breast milk is very sweet due to the concentration of the sugar lactose, so from day one we learn to develop a sweet tooth.

One study showed how even the mere expectation of sugar can affect our cognitive ability. Scientists found that when study subjects swished sugar water around in their mouths and then spit it out, they performed better on cognitive tests than the subjects who had swished water that had been artificially sweetened. And there is a good reason why sugar is addictive. Eating sugar prompts the release of the hormone serotonin from the same area of the brain that responds to heroin and cocaine, inducing a feeling of happiness and euphoria.

It’s not always obvious where sugar is hiding in the foods we eat. While our consumption of table sugar is down, the amount added to processed foods is increasing. Many people are surprised to find how much sugar is added to such things as bologna (1.18 tsp. per 4 slices), ketchup (1.77 tsp. per 3 tbsp.) and low-fat fruit yogurt (6.16 tsp.). A couple of spoons of barbecue sauce have about as much sugar as a glazed donut! Add in the sugars typically contained in soups, sauces and breads, and it’s easy to see why obesity is becoming such an epidemic. The more we get, the more we want. A sudden rush of sugar spurs the release of insulin, which causes the infamous “sugar crash” and makes us crave even more to combat it.

However, it is possible to overcome an addiction to sugar, just as it’s possible to overcome an addiction to any other substance. Gradually use less where you can, such as in coffee or tea and in your breakfast cereal. You can also reduce or eliminate your consumption of soda (including artificially sweetened soda, which still makes you crave the sweet taste) and water down any fruit juices you may drink. After a while, your body does adjust to the taste. After a few months, if you suddenly are given coffee with sugar in it, you may find it tastes odd. Try to avoid buying store-bought desserts, and if you make your own, reduce the amount of sugar called for in the recipe. Many baked goods can use unsweetened applesauce as a substitute for 2/3 of the sugar required.

Our society has made it difficult to resist sugar, but it’s not impossible, and the less sugar you eat, the better it will be for your overall health.

 

The Benefits of Phosphorus

The Benefits of Phosphorus

periodic-table-phosphorus-200-300Our need for phosphorus is almost as great as our need for calcium. In fact, phosphorus is the second-most abundant mineral in the human body after calcium, so it’s no wonder that it has a major part to play in achieving good health. It works with calcium to ensure strong bones and teeth, helps the kidneys to filter waste products, and plays a key role in how the body uses and stores its energy. On top of all that, phosphorus is also necessary for the production of DNA and RNA, and is needed to produce, maintain and repair our body’s cells.

Even though phosphorus is as important to maintaining healthy bones and teeth as calcium, we do not hear as much about its importance in our diet as we do about calcium. This is likely because most people get enough phosphorus from their diet. In fact, some get more than is necessary (particularly if they’re not getting enough calcium), which can cause a number of health problems. Too much phosphorus in relation to calcium can lead to an increase in your risk of cardiovascular disease. The greater your phosphorus intake, the more calcium you need.

The daily recommended intake for phosphorus is as follows:

Babies 0 to 6 months: 100 mg/day
Babies 7 to 12 months: 275 mg/day
Children 1 to 3 years: 460 mg/day
Children 4 to 8 years: 500 mg/day
Adolescents 9 to 18 years: 1,250 mg/day
Adults: 700 mg/day

Conditions such as diabetes, malnutrition and alcoholism can increase a person’s risk of phosphorus deficiency. This can also be a problem for those who have conditions that create problems with absorption, such as celiac disease and Crohn’s disease. Symptoms of phosphorus deficiency may include weak bones, stiff joints, fatigue, anxiety, loss of appetite, bone pain, irritability and irregular breathing.

 
Foods high in protein have the greatest amount of phosphorus. Meat and dairy products, as well as nuts, eggs and legumes are good sources of phosphorus in the diet. It can also be found in whole grains and dried fruits. You generally do not have to worry about not getting enough phosphorus in your diet, as it is so prevalent in most of the things we eat. For example, one three-ounce serving of meat contains between 150 mg and 250 mg of phosphorus. What is more important is that you get a sufficient amount of calcium so that it will balance out any excess phosphorus in you get from your diet so that it does not lead to adverse health issues.

Pros and Cons of Drinking Juice

Pros and Cons of Drinking Juice

????????????Look on any supermarket’s shelves these days and you’ll see a huge variety of fruit juices, far more than were ever seen in our parents’ day. Orange juice (or occasionally grapefruit, apple or tomato juice) was the juice that typically appeared on most American breakfast tables. Now, it is possible to get juices in all manner of combinations, including such exotic fruits as mango, guava, pomegranate, goji berry and more. And although many of these juices have a healthy serving of vitamins and minerals, they also may have their fair share of calories and sugar. So is fruit juice good for us or not? Following are some of the pros and cons of drinking fruit juice.

Pros:

Easy way to get fruit – One 4-ounce glass of fruit juice counts for one full serving of fruit, so if you are too rushed to eat an apple you can down some juice. While fruit juice does not contain the fiber that makes eating the whole fruit so healthy, it is still better than getting no fruit at all.

Good source of vitamins and antioxidants – One glass of orange or grapefruit juice can supply more than your daily requirement of vitamin C, boosting your immune system and providing you with free-radical-fighting antioxidants. It is also an excellent source of folic acid (which prevents birth defects and is good for heart health) and potassium (which helps to regulate blood pressure).

Cons:

High in calories – Pam Birkenfeld, as pediatric nutritionist at New York’s Nassau University Medical Center says, “Parents tend to think that because fruit juice is fat-free and comes from nature, it’s OK. But what they often don’t realize is that it is a very concentrated source of calories that generally does not fill you up, just out.” There is an average of 140 calories in an 8-ounce glass of fruit juice. If you consume a few glasses each day, those calories can add up. In contrast, an orange has only about 60 calories.

High in sugar – Our increased consumption of sugar has been implicated as being a major contributor to the skyrocketing rates of obesity observed in the Western world. Studies have shown that children who are overweight drink 65 percent more sugary juices than children of normal weight. Some juices contain more sugar that sweetened soft drinks. Grape juice, for example, has 50 percent more sugar than Coca Cola.

Bad for your teeth – One study found an 84% reduction in the hardness of tooth enamel after drinking orange juice for just five days. Researchers believe other juices may have a similar effect, as their acidity is similar. Tooth decay and cavities in children as young as two or three years old have become commonplace, and dentists point to the increased intake of fruit juice as the cause. The combination of acid and sugar is the perfect storm for tooth decay. Experts advise that children drink fruit juice no more than once a day, and instead drink milk or water. If fruit juice is taken, it can be watered down to dilute the acid concentration.
By weighing these pros and cons you can decide for yourself how much juice you and your family should drink to get the benefits of drinking fruit juice while minimizing the drawbacks.

The Benefits of Potassium

The Benefits of Potassium

???????As the third most common mineral in the body, potassium is responsible for supporting a wide range of bodily activities. Without sufficient potassium, the heart, brain, kidneys and muscles would not function properly. However, the Western diet’s preponderance of processed foods has created a population with a growing risk of potassium deficiency.

Potassium is an electrolyte that is crucial to the body’s electrical circuitry so that proper signals are conducted to and from the brain and between cells. It works in conjunction with the minerals sodium, calcium, chloride and magnesium. Simply moving a muscle requires potassium. Potassium helps to regulate the heart, which is triggered by potassium to contract, squeezing blood through the body a hundred thousand times each day.

In addition to keeping our muscles and heart in good working condition, potassium is also responsible for healthy bone maintenance, protecting against osteoporosis, reducing high blood pressure, lowering cholesterol and helping the kidneys to filter blood. It can also reduce feelings of stress and anxiety and keeps the body’s water levels balanced.

The recommended daily intake of potassium is as follows:

Infants birth – 6 months: 400 mg/day
Infants 7 – 12 months: 700 mg/day
Children 1 -3 years: 3,000 mg/day
Children 4 – 8 years: 3,800 mg/day
Children 9 – 13 years: 4,500 mg/day
Adolescents and Adults 19 years and older: 4,700 mg/day
Breastfeeding women: 5,100 mg/day

Most Americans are potassium deficient. “Relying on convenience and restaurant foods and not eating enough fruits and vegetables is why so many people don’t get enough potassium. Fresh and lightly processed foods, including dairy and meat, have the most potassium,” according to registered dietitian, Marla Heller.

An excess of sodium in the diet (which is common among Americans) can increase the amount of potassium you need. Others at risk of potassium deficiency (hypokalemia) are those who experience diarrhea, vomiting, malabsorption syndromes (such as Crohn’s disease) and excessive sweating. Alcoholics, smokers, drug users, athletes (or anyone who uses their muscles excessively), and those who use diuretics are also prone to hypokalemia. Symptoms include irregular heartbeat, muscle cramps, irritability, chronic diarrhea, weakness and stomach problems.
Food sources abundant in potassium are meat, poultry, fish (cod, salmon, and flounder), dairy products, legumes and fruits and vegetables (particularly bananas, citrus, avocados, tomatoes, potatoes and green leafy vegetables such as Swiss chard). Cooking destroys potassium, so try to eat potassium-rich foods either raw or minimally cooked (lightly steamed or roasted).

Why Some Foods Just Make Us Feel Better

Why Some Foods Just Make Us Feel Better

??????????????????????There is a reason why you reach for the chocolate when you are feeling depressed. Scientists have been studying the connection between food and mood for a number of years, and they have found that the foods we eat have a definite influence on the state of our mood. After all, foods are essentially chemicals when broken down by the body’s digestive processes, and those chemicals all have some influence on the brain. The neurotransmitters most responsible for mood (such as serotonin, dopamine and acetylcholine) are all affected by what we eat.

Our feelings can be affected by foods in other ways as well. Something as simple as fluctuations in the level of our blood sugar can make a big difference mood-wise. Low blood sugar can make you feel tired and irritable, but too much sugar at once in our bloodstream can make you hyper. Sticking to a low-glycemic diet, in which the sugars from food are released slowly into the bloodstream, can keep your mood on a more even keel.

Carbohydrates may help to boost your mood (which is why we crave “comfort foods” like macaroni and cheese). Carbohydrates (such as those in fruits, vegetables, legumes and whole grains) assist in the production and absorption of tryptophan into the brain. With the assistance of B-vitamins, tryptophan is important for the synthesis of serotonin, a neurotransmitter that can boost mood. A study performed by scientists at Arizona State University found that a very low-carb diet caused feelings of fatigue and discouraged overweight subjects from exercising. Just be sure to avoid simple carbohydrates such as foods containing refined flour and refined sugar, as they will just spike your blood sugar and cause a subsequent energy and mood crash.

The consumption of foods rich in omega-3 fatty acids has been shown to help to ward off depression and reduce anger and irritability. Researchers believe that omega-3s enhance the pathways of important neurotransmitters. Study subjects who suffered from depression were found to have low levels of omega-3. Eating fatty fish three times a week, such as sardines, mackerel, herring and salmon, can help you get a healthy dose of omega-3 fatty acid.

Just as there are foods you should eat to improve your mood, there also foods you should avoid eating. In addition to refined foods, you should avoid excessive consumption of foods containing caffeine, alcohol, hydrogenated oils and artificial additives. These all have been shown to contribute to anxiety, depression and difficulty concentrating.
Foods high in vitamin D (fortified milk, sardines) and selenium (seafood, beans, nuts, seeds, legumes, lean meat and whole grains) can also boost feelings of happiness. A little dark chocolate would not go amiss either. Just a small amount (1.4 oz) of dark chocolate can reduce cortisol and catecholamines, the stress hormones. Just don’t overdo it, as too much sugar can negate chocolate’s beneficial effects.
