Aging population and food intolerances to carve food trends in 2012: report
The gold standard is an oral food challenge, which involves eating small doses of the suspect food under medical supervision. Food intolerances are unpleasant reactions that do not involve the immune system, according to the National Institute of Allergy and Infectious Diseases. They can be caused by enzyme deficiencies, sensitivities to food additives such as sulfites and monosodium glutamate, or reactions to naturally occurring chemicals. For example, people who lack an enzyme needed to digest sugar in milk have lactose intolerance. Sulfites used to preserve dried fruit, canned goods and wine trigger asthma attacks in sensitive people. Adverse reactions to wheat or the protein gluten come in several forms. Celiac disease is an immune system reaction to gluten that causes inflammation in the small intestine. A wheat allergy is an allergic reaction to wheat, almost always caused by the gluten. And gluten sensitivity means a person has symptoms after ingesting gluten but doesn’t have either of the other conditions, said Stefano Guandalini, founder and medical director of the University of Chicago’s Celiac Disease Center.

Weight gain: Are food intolerances to blame?
They’re much more common and difficult to diagnose than food allergies. People have trouble attributing what they’re eating to a certain symptom because the symptom might not occur for a few days. Intolerances are often confused with allergies because of the similarities in symptoms, but they’re not the same. Symptoms of intolerance may include diarrhea, stomach pain and vomiting, but not hives, airway swelling or anaphylaxis. Sandquist says that intolerances can also cause cravings, tiredness, bloating and even headaches a few days later. “I recommend logging what you eat and tracking your symptoms over time,” she says.

Some child allergies can be lethal
Tamara Duker Freuman Nowadays, it seems everyone has a restricted diet of some sort. Some people avoid milk for a variety of reasonseither due to lactose intolerance, an inability to digest the milk sugar in dairy products, or concerns that dairy makes them congested. Glutenthe main protein found in wheatis increasingly being shunned by health-conscious consumers who believe it to be a “toxin” responsible for everything from bloating and weight gain to poor energy and “brain fogs.” And the latest newcomer to the food intolerance scene is fructosethe primary sugar in fruit juice, honey, agave nectar, and high-fructose corn syrupwhich research suggests may be poorly digested in up to 30 percent of the Caucasian population. It seems we’re a nation suffering from a case of collective indigestion. And it raises a few important questions. What is a food intolerance? Is food intolerance truly on the rise? Is there something real behind this trend, or is it all in our minds? Unlike true food allergies , which involve a systemic and potentially life-threatening immune response to the protein in an offending food, a food intolerance tends to trigger symptoms which are unpleasant, but not dangerous per se.

Food Intolerance: Fact and Fiction
Food intolerances versus food allergies Unlike food allergies that are acute and severe, food intolerances can be tricky to pinpoint. If someone with a peanut allergy eats peanuts,she can go into anaphylactic shock and immediately need medical attention this is acute and severe. Someone with a food intolerance, on the other hand, will experience subtle symptoms that can worsen over time. Food intolerances fire up your immune system just like food allergies do, but their effect is more subtle and symptoms may not appear for several hours or even days, after youve eaten a highly reactive food. So you may not make the connection between, say, the egg-white omelet you had for breakfast and that late-afternoon splitting headache. Food intolerances develop when you repeatedly eat a highly reactive food. They can trigger leaky gut, immune reactions and inflammation, and can also stall fast fat loss. How do you know if you have food intolerances? Food intolerances trigger numerous symptoms.

Lucy says: “The first thing to point out is that lactose intolerance is not an allergy. People will have a certain tolerance point, meaning they can manage a little, but maybe not a whole glass of milk. “Most people with a lactose intolerance do not need to exclude all dairy in pre-made foods as these typically contain small amounts of lactose and do not cause symptoms. This means that many people with a lactose intolerance could still eat a small yoghurt for example.” Story continues below the slideshow: Loading Slideshow Crisps, flavoured nuts and tortillas Any manufactured food, bakery, butchers products or deli items If you do want to take steps towards a dairy-free existence, The Food Doctor nutritionist Alice Mackintosh says: “Though there isnt a lot of specific research that suggests dairy is bad for us, many people find they generally feel better not over doing it. Many of my female clients also give up diary if they have hormonal imbalances (such as PCOS, endometriosis, PMS or problem skin) owing to the slightly elevated hormone levels in milk.” Soya is the most well-known alternative for dairy free diets.

Are food allergies making me gain weight?
Fructose is a sugar that’s found in fruits, honey and some syrups. It’s also a basic component in table sugar (sucrose) , and it’s used to sweeten many processed foods and beverages. In addition, sorbitol a sugar alcohol is converted to fructose during digestion. Sorbitol is a sugar substitute often used in diet drinks, ice cream, mints, cough syrups and sugar-free chewing gum. You should avoid foods containing fructose. In addition to fruits, honey, syrups and table sugar, watch out for high-fructose corn syrup , powdered sugars, regular sodas, flavored waters, sports drinks and sweetened milks. Read food labels carefully to avoid fructose. The term fructose intolerance covers two conditions: hereditary fructose intolerance and fructose malabsorption.

Cells and chemicals from the immune system enter the lung tissues and the breathing tubes become hyper-reactive. This means the tubes are easily triggered into constricting or narrowing, making it harder to move air through the lungs, and breathing becomes difficult. In addition, the mucosa or lining becomes swollen. Excessive production of mucus occurs. These changes add to difficult breathing.

Food Allergy, or Food Intolerance?
Antioxidant None of these I’m not sure An aging population means that grocery store shelves will be increasingly lined with foods that come with added health claims while younger consumers with food intolerances will drive demand for gluten-, nut- or dairy-free foods in 2012, predicts a market research group in the UK. According to the latest trendspotting predictions of Leatherhead Food Research, a strong interest in maintaining a healthy, active lifestyle among retiring Baby Boomers will fuel more product launches in the functional food market next year — foods that come with health claims. Expect to see more products with glucosamine for joint health, for example, and foods with added omega-3 for brain health, analysts say. Artery-cleaning products are also poised to make a breakthrough in the functional food market, experts say, and seduce older consumers with promises of cardiovascular benefits. Meanwhile, “free-from” foods — labels that indicate gluten-, dairy-, soy- and nut-free products — will experience rising popularity in 2012, Leatherhead says. And its not necessarily consumers with food allergies who are driving this demand, but those who are voluntarily cutting out ingredients and making changes to their diets.
