The idea that diet could have a role to play in preventing the signs of asthma is starting to gain ground, with studies highlighting certain deficiencies in patients or warning against the consumption of certain foods. On World Asthma Day, May 2, Relaxnews spoke to Dr. Bertrand Delaisi, a pediatric pulmonologist at Clinique Marcel Sembat in Boulogne-Billancourt, France, for an overview of what’s currently known on the subject.
The prevalence of asthma has increased considerably in recent decades, in parallel with changes in lifestyles and dietary habits, tending towards diets rich in carbohydrates and fat, and low in fiber.
As well as pollutants, allergens, passive smoking and air pollution, allergy specialists are increasingly interested in how diet can promote or modify the development of asthma on a physiopathological level.
Eating ham, cured sausage or smoked meats at least four times a week could aggravate the symptoms of asthma over time, concludes a study carried out by researchers at Inserm, the French National Institute of Health and Medical Research, published in January in the medical journal Thorax.
On the contrary, consuming fiber may influence the gut flora and could reduce inflammation in the bronchial tubes. A diet rich in fruit and vegetables and vitamin C — and especially vitamin D (calf’s liver, soy, egg yolks) — could, therefore, help limit the risks of asthma, according to Dr. Bertrand Delaisi, a pediatric pulmonologist at Clinique Marcel Sembat in Boulogne-Billancourt, France.
The same goes for omega-3 fatty acids, present in oily fish and other foods (walnuts, canola oil), which can relieve inflammation, including in the respiratory airways. People whose diets are rich in omega-3 have a lower risk of suffering from asthma than those whose intake is limited. They could also be beneficial to people who already suffer from the condition.
Foods containing quercetin could reduce the frequency of asthma attacks, as this antioxidant flavonoid is an anti-inflammatory. Studies carried out in vitro found that quercetin inhibited the liberation of inflammatory substances by mast cells, which play a role in allergic reactions, mirroring certain anti-asthma medications. This antioxidant is found in onions, mustard oil, tea and apples.
An estimated 300 million people worldwide suffer from asthma.
When mid-afternoon fatigue sets in, it’s easy to reach for a cup of coffee or a sweet treat for a quick boost. Unfortunately, the energy boosting effects are short-lived and often lead to a crash later in the day.
Instead, experts say it�s best to opt for a snack that’s rich in protein, fiber, and complex carbohydrates for a natural energy boost. Here are nine of the best options for energy-boosting snacks and meals that will keep you alert throughout the entire day.
Nuts. Almonds, pistachios, and other nuts contain important nutrients like magnesium and B vitamins which help convert food to energy. Pistachios have a powerful combination of protein, fiber and heart healthy monounsaturated fats, making them a great snack choice.
“Research shows that people with low magnesium levels tend to tire more quickly during exercise due to magnesium’s role in energy metabolism,” dietitian Rachel Berman says. A lack of B vitamins can cause fatigue, irritability and poor concentration. Berman suggests one serving, or about 23 nuts, to keep calories low.
Whole grains. “Thanks to fiber, whole grains help prevent the blood-sugar crashes that happen after consuming refined or simple carbohydrates,” says Berman. Whole-grain carbohydrates, like popcorn, are a great afternoon snack choice. The volume of popcorn also keeps you satisfied longer than chips or crackers. Try popping your own and adding herbs and spices, instead of butter and salt.
Nut butters. Peanut butter and almond butter can provide a great energy boost. They’re filled with health fats, protein and fiber, which help keep blood sugar levels stable. Berman says make sure you avoid brands with added sugars and stick to just a 2-tablespoon serving.
According to a study done at the University of Cambridge in England, protein also activates cells that help keep you awake. Researchers found that the cells responsible for our energy levels respond better to amino acids in proteins than in other nutrients.
Fish. Salmon is filled with omega-3 fatty acids, nutrients that can boost energy and mood. Berman says the nutrients found in fish have also been found to improve memory and reduce depression. The healthy fats found in fish like salmon also help lower blood pressure and bad cholesterol, making them heart healthy choices.
Bananas. These sweet treats are a great source of fiber, B vitamins, and potassium � nutrients that promote sustained energy. Bananas make for a great pre- and post-workout snack. Berman suggests a banana with a cup of yogurt for an energizing snack with fiber and protein for sustained energy.
Kale. This leafy green contains the amino acid L-tyrosine, which is great for an energy boost. The leafy green also contains fiber and a number of antioxidants which help stabilize blood sugar, says Berman.
Oatmeal. A dish of this high-fiber, filling breakfast staple can provides lasting energy all day long. Dieticians recommend looking for breakfast foods that contain at least 3 grams of fiber per serving. Options can include: oatmeal, whole-grain breads or pancakes, high-fiber breakfast cereals and quinoa.
Hummus. Made of garbanzo beans, sesame-based tahini, olive oil, and lemon, hummus is full of nutrients that contribute to high energy levels. The fiber and protein in the beans help stabilize blood sugar and boost energy. Use hummus as a veggie dip or a sandwich spread for a great snack or healthy lunch.
Greek yogurt. Compared to regular yogurt, Greek yogurt contains twice as much protein, making it a great breakfast or snack option. “The thick, indulgent texture is the perfect canvas for a variety of toppings that can make it even more substantial,” says dietitian Kari Kooi. Add fruit, nuts, or low-calorie granola to make it even more nutritious.
A new study found that gluten-free diets could increase cardiovascular risk in people without celiac disease. The study claims that gluten-free diets among people without celiac disease is not associated with risk of coronary heart disease, but such diets result in a low intake of whole grains, which are linked to cardiovascular benefits.

People with celiac disease, on the other hand, usually have to follow gluten-free diets because the protein found in wheat, barley, and rye can cause them to develop gastrointestinal issues.
Gluten-free diets should not be encouraged to people without celiac disease
The study was published in the BMJ on May 2, and researchers noted that cutting out gluten unless medically necessary can increase a person�s risk of cardiovascular problems. The researchers analyzed data from 64,714 women and 45,303 men who worked in the health industry, each of whom had no history of heart disease.
Subjects were asked to fill a detailed food questionnaire in 1986, and they were required to update it every four years until 2010. The scientists noted that they saw no significant association between gluten intake and heart disease risk.
�Long term dietary intake of gluten was not associated with risk of coronary heart disease. However, the avoidance of gluten may result in reduced consumption of beneficial whole grains, which may affect cardiovascular risk,� wrote the researchers on the study.
Gluten is a storage protein found in wheat, rye, and barley, and it is known to trigger inflammation and intestinal damage in people with celiac disease. According to the researchers, celiac disease is present in 0.7 percent of the U.S. population, and because it is associated with an increased risk of coronary heart disease, patients are recommended to shift to a gluten-free diet.

The study claims that currently many people reduce gluten in their diet because they believe that it will lead to general health benefits. A national survey showed that in 2013 nearly 30 percent of adults in the U.S. reported that they were cutting off or reducing their gluten intake. However, the researchers noted that despite the rising trend in gluten restriction, no study has linked gluten with the risk of coronary heart disease in people without celiac disease.
�Although people with and without celiac disease may avoid gluten owing to a symptomatic response to this dietary protein, these findings do not support the promotion of a gluten restricted diet with a goal of reducing coronary heart disease risk,� warned the researchers.
Researchers concluded their study saying that it found no evidence of gluten diets and coronary disease among male and female health professionals analyzed for more than 25 years and that further research is needed to investigate the link between gluten and cardiovascular problems, as their study was merely observational.
You may think you eat food to fuel your body but that’s not all it does. Emerging research shows that what you eat actually influences the composition of your microbiome, which can help you feel healthier and lose weight.
“We have entered the gut-health era of diet and nutrition and it will be here for a long time indeed. The science is simply too persuasive to suggest otherwise,” top expert Jeannette Hyde says.
Microbiome is the term used for the bacteria, particularly those living in the intestines.
Hyde, a London-based certified nutritional therapist, is the author of “The Gut Makeover: 4 Weeks to Nourish Your Gut, Revolutionize Your Health and Lose Weight,” a popular book in the U.K., which was published here on May 2.
Here are excerpts from her recent interview with Newsmax Health.
Q:Why is our microbiome important?
A: Our microbiome communicates with our hormones to keep them balanced, it influences how aggressively we extract calories from food eaten, and it also communicates with our immune system and signals to our brain.
Q: What is a healthy microbiome like?
A: A healthy microbiome is dominated by beneficial bacteria and contains lots of different varieties of bacteria. An unhealthy microbiome is dominated by nasty types of bacteria, with the good ones left in the minority, and also has little variety of bacteria.
Q: What health problems does an unhealthy microbiome cause?
A: When the microbiome is out of balance, or deranged, we may experience digestive issues such as chronic bloating, wind, loose stools, constipation, or alternating between the two.
Q:How does a healthy microbiome help you?
A: A healthy microbiome is important to have a healthy microbiome keeping your weight, mood, and immune system in check. Early studies are also showing that eating foods to enhance the microbiome can lead to improvements in memory and mood, and autoimmune disorders to name a few
Q: How does the typical American (Western) unbalance the microbiome?
A: In the Western diet we often have a lot of grains (usually dominated by wheat) so there is very little variety of color, and the color beige dominates. It’s also often high in sugar, artificial sweeteners, and unhealthy trans fats. Artificial sweeteners can disrupt your microbiome too.
Q: Why is eating for your microbiome better than counting calories for weight loss?
A: The microbiome has been shown to influence on our hunger hormones, so a deranged microbiome could knock your hunger hormones out of balance, giving you cravings all the time.
Q: What is your diet for a healthy microbiome?
A: My diet features a low-grain Mediterranean diet in which you bombard your gut with diversity of plants, satiating proteins, and good oils such as extra virgin olive oil. After 2 weeks, you can add in foods that have healthy bacteria, like fermented milk kefir and smelly unpasteurized cheese Roquefort full of bacteria to plant in your gut, or sauerkraut or miso if you can’t tolerate dairy.
Here are Jeannette Hyde’s 6 tips for a healthy microbiome:
Bombard your body with diversity. It really can make food enjoyable having lots of different ones to look forward to. Get into the habit of trying to get as many different types of vegetables into each meal – chop lots of different fresh herbs on top, throw over a handful of pomegranate seeds, grate some carrot.
Drink fermented milk kefirevery day like medicine. It’s a convenient and delicious way to get tens of billions of beneficial bacteria into your gut in one sitting. You can blend it in a blender with fruit and nuts or mix it with extra virgin olive oil, lemon juice and a bit of garlic for a delicious salad dressing.
Make cold potatoes your friend – potatoes have been demonized for too long! They can be very good for your microbiome and consequently your weight. When potatoes cool down they form resistant starch, a type of fiber which cannot be digested in the top half of the digestive tract, making you feel full, and survive all the way to your colon where you gut microbes dine out on them.
Enjoy flax seeds. Often fairly inexpensive, flax seeds, known also as linseeds, are super foods for your gut bacteria and produce a fuel to keep your gut lining in good repair. You can use them in a shake each morning. It’s simple good housekeeping for the microbiome.
Eat Slowly. Eating slowly is so important to good digestive health. If we wolf down our food, undigested food can reach the colon and lead to a deranged microbiome, bloating, hunger and more. It’s such a simple action, and costs no money, and can deliver big results.
Try a 12-hour overnight fast. This is an easy way to give your microbiome a good long stretch to regenerate, and can help rebalance your hunger hormones so you feel less hungry generally.
Whether we�re starting our day with a strong cup of coffee or indulging in a mid-afternoon pick-me-up (preferably of the dark chocolate variety), caffeine is a drug that many of us don�t want to quit. And thankfully, we don�t have to: A new scientific review offers reassurance that, in moderate amounts, caffeine is perfectly healthy.
Specifically, the paper confirms the results of the last big review done on caffeine safety, way back in 2003: that intake levels of up to 400 mg a day, or about four 8-ounce cups of coffee, are not associated with health risks for adults. (Yay!) The results, published in Food and Chemical Toxicology, were presented over the weekend at the Experimental Biology conference in Chicago.
�After decades of research and thousands of papers, we know a lot about caffeine,� says lead author Daniele Wikoff, PhD, health sciences practice leader at ToxStrategies, a private scientific consulting firm. �And what our findings truly confirm is that having caffeine as part of your daily diet is still acceptable and without adverse effects.�
Pregnant Women and Caffeine
The new review also found that existing upper limits for pregnant women (300 mg a day) and children (about 1.1 mg per pound) continue to be supported by scientific data, as well. �This should give pregnant women some comfort that they do not need to eliminate caffeine from their diet,� says Wikoff.
Although there�s no change to the current recommendations, an update was long overdue, says Wikoff. Since the widely-cited 2003 review on caffeine was conducted by Health Canada, more than 10,000 papers have been published on the drug�s effects on various aspects of health.
That’s why the North American branch of International Life Sciences Institute (ILSI), a nonprofit foundation dedicated to advancing the understanding of nutrition and food safety, decided to commission an analysis on more recent literature. To start, the Institute recruited ToxStrategies to comb through more than 700 studies conducted on humans and published between 2001 and 2015.
The researchers narrowed those studies down to 426 for inclusion in the review, all of which focused on how caffeine related to five specific topics: toxicity, bone health and calcium intake, cardiovascular effects (including blood pressure and heart rate), behavioral health (including headaches, mood, and sleep), and reproduction and development (including fertility, miscarriage, and birth defects).
The Effects of Caffeine on Americans
Despite all the new research, the paper�s conclusions remain generally the same as the previous review�s. More than 90% of Americans currently consume less than 400 mg a day of caffeine, the authors wrote, and the findings of the new review “support the safety of standard consumption practices in the United States.�
The authors did note that studies on caffeine in children were limited. While they found no need to recommend a change in current recommendations, they do say that more research on this age group would be valuable. (The American Academy of Pediatrics maintains a long-held position that caffeinated beverages, especially energy drinks, should be avoided in children.)
And because research on the general safety of caffeine is so plentiful, they also recommend that future studies shift their focus to unhealthy populations, sensitive groups, and ways that people may be affected differently on an individual level.
ILSI North America receives funding from the American Beverage Association and the National Coffee Association. Both organizations �received periodic progress reports but did not participate in any aspect of the systematic review,� the authors note in the paper. In addition to scientists from ToxStrategies, the research team consisted of seven scientific advisory board members from academic institutions across the U.S. and Canada, with expertise in the paper�s different areas of focus.
The studies included in the review looked at a variety of caffeine sources, including coffee, tea, chocolate, other beverages, and supplements, but the review did not evaluate the health effects associated with these different sources separately. When considering your caffeine intake, says Health�s medical editor Roshini Raj, MD, it’s important to keep in mind the entire food or drink.
Plain coffee, for example, is rich in antioxidants and may reduce the risk of heart disease, stroke, and diabetes. Soda and fancy coffee concoctions, on the other hand, can be high in calories or contain artificial sweeteners, while energy drinks can contain sugar and other stimulants that have been associated with health risks.
Dr. Raj also says that just because 400 mg a day of caffeine is safe, that doesn�t mean it�s right for everyone. �We don�t all metabolize caffeine the same way: Some people find that even a little cup of coffee or tea can make them restless,� she wrote in a recent column for Health. �Listen to your body, and if you tend to get jittery, try spacing out your caffeinated beverages,� she added.
If you find that you�re becoming dependent on caffeine, make sure you�re getting enough sleep�or talk to your doctor about why else you might be so tired, Dr. Raj adds. You can always try an all-natural energy enhancer, too: A recent study found that 10 minutes of stair-walking provided a better boost than a 50-mg caffeine pill.

Back pain and symptoms of sciatica can affect a majority of the population throughout their lifetime. Research studies have demonstrated that people who are overweight or obese experience more back complications than people with a healthy weight. A proper nutrition along with regular physical fitness can help with weight loss as well as help maintain a healthy weight to eliminate symptoms of back pain and sciatica. Chiropractic care is also another natural form of treatment which treats back pain and sciatica utilizing manual spinal adjustments and manipulations.
Energy drinks are known for their high caffeine content, which often tops that of soda and even coffee. But they seem to affect people�s hearts and blood pressure differently than other caffeinated beverages, suggests a small new study published in the Journal of the American HeartAssociation.
In the study, researchers divided 18 men and women into two groups. Half were given a 32-ounce commercially available energy drink with 320 mg of caffeine, as well as other ingredients like taurine and ginseng (both dietary supplements). People in the other group were given a soda-like control drink of the same size that contained the same amount of caffeine with a bit of lime juice, cherry syrup and carbonated water. After six days, the groups switched and drank the other beverage.
Results of Consuming Energy Drinks
The researchers measured everyone�s blood pressure at the start of the study and one, two, four, six and 24 hours after drinking the beverage. They also measured everyone�s heart activity using an electrocardiogram.
People who drank the energy drinks had a QT interval�meaning the time it takes the heart�s ventricles to prepare to beat again�10-milliseconds higher than those who drank the caffeinated control beverages. Irregularity in the QT interval can sometimes lead to abnormal heart beats. Fletcher says that the disparity may be important, since some medications that affect the QT interval by 6 milliseconds carry warning labels.
Both groups had higher blood pressure after their drinks, though never out of normal range. The blood pressure of people who had the control drink returned to baseline levels after six hours. But when people drank the energy beverage, their blood pressure remained elevated for more than six hours. The researchers believe that could mean that the other ingredients in energy drinks may alter blood pressure beyond the effects of caffeine alone.
�What the growing body of evidence is pointing to is that there are effects on the heart that are different than caffeine alone,� says study author Emily Fletcher, a deputy pharmacy flight commander from David Grant U.S.A.F. Medical Center at Travis Air Force Base in California. �Consumers should be aware that drinking an energy drink is not the same as drinking coffee or soda.�
More research is needed. The study was small, and researchers only looked at the effects of the beverages on people who were healthy�and not at the differences over the long term. The American Beverage Association, which represents the non-alcoholic beverage industry, said in a statement that �energy drinks have been extensively studied and confirmed safe for consumption by government safety authorities worldwide including a recent review by the European Food Safety Authority.�
Fletcher says that the findings suggest people should approach energy drinks with some caution, especially those who have risk factors for heart issues. �I would recommend only moderate consumption of energy drinks and particular avoidance in people with underlying cardiac disease or hypertension,� says Fletcher, �or during activities that would also increase your blood pressure and heart rate, such as exercise or sports.�

Mothers who eat a diet high in fructose-containing sugars while pregnant or breastfeeding are more likely to have a child with fatty liver disease, increasing their chances of developing obesity or type 2 diabetes according to new Australian research.
Carried out by the University of South Australia, the animal study looked at female rats given water supplemented with fructose-containing sugars including sucrose or high fructose corn syrup (HFCS) before, during and after pregnancy.
The amount of sugar was equivalent to levels found in standard soft drinks.
After they were born, the offspring were either weaned by a mother who had access to the fructose-containing beverage, or by a mother who had access to water only.
The team then analyzed the offspring’s body weight, fat mass and glucose control and analyzed their tissues to find out the amount and type of fat in their livers.
They found that the offspring from mothers who had consumed the drink high in fructose were more likely to have a fatty liver, and that this was especially true for offspring who were weaned by mothers who drank the fructose-containing beverage.
Fatty liver can also have a negative effect on metabolic health, potentially leading to obesity or type 2 diabetes in the future.
The results also suggest that the timing of exposure to fructose sugars is important, and highlights the importance of diet for breastfeeding mothers.
Dr Sheridan Gentili, lead investigator of the study cautioned that, “As there are differences in physiology between humans and rodents, we need to be careful when translating this research directly to humans.”
However, she also added that, “This study highlights the importance of maternal nutrition during the lactation period. Guidelines for consuming added sugars or sugar-sweetened beverages during pregnancy should consider this.”
As well as soft drinks, many cereals and other processed foods also contain fructose-containing sugars.
The study can be found online published in The Journal of Physiology.
