Food sensitivities or intolerances and food allergies are often confused. One of the main differences between the two is that food sensitivities and intolerances are quite common and do not involve an immune system response. Food sensitivities/intolerances develop in the digestive tract in response to food and can trigger irritation of the gut.
This occurs when the gut struggles to properly digest food that is consumed, oftentimes causing certain amounts of undigested food to linger in the intestinal tract, leading to an inflammatory response as well as digestive discomfort that reflects a sensitivity and intolerance to that particular food . Low levels of digestive enzymes, sensitivity to naturally occurring substances in food (e.g., lactose), or reactions to additives (e.g., preservatives, artificial colors, etc.) may lead to food sensitivities. The symptoms include: nausea, cramping, constipation, diarrhea, gas, bloating, and may even cause behavioral responses such as...
Leaky gut, also known as increased intestinal permeability, is a digestive disorder that develops when tight junctions loosen or become damaged and allow undigested food, bacteria, or toxins to leak through the wall of the intestine . Tight junctions are small gaps in the intestinal lining that promote the transfer of nutrients, while preventing undesirable compounds from passing through the intestinal tract into the bloodstream.
Unfortunately, when tight junctions loosen, harmful substances begin to accumulate in the bloodstream and this may cause various types of inflammatory issues . In addition to inflammation, symptoms such as food sensitivities, bloating, gas, cramps, and additional digestive problems may develop as a result of leaky gut.
Although some healthcare providers do not consider leaky gut as an actual medical diagnosis, mounting scientific evidence indicates that this a true condition that affects many people and may be associated with the onset of...
Getting kids to eat a healthy diet can be challenging in the best of times, and now that we’re facing the coronavirus pandemic, a diet rich in vitamins and minerals is more important than ever. Our immune systems depend on micro- and macronutrients that we get from our diets to protect us from infection and to speed recovery from illness.
Both autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) have been associated with dietary deficits that affect immunity, and correcting these deficits improves symptoms.1,2 Several of the deficient vitamins that are observed in both disorders are important for a strong immune system, including vitamin D, zinc, and selenium, among others.3
Inflammation and immune dysregulation are known contributors to ASD, and more recent evidence links them to ADHD as well.4,5 Since diet affects immunity, making sure that kids with ASD and ADHD are getting all of the nutrients they need is critical to protecting them...
Omega-3 fatty acid supplements are well known for their ability to support heart health, but clinical research also shows that omega-3s promote enhanced mental performance [1, 2].
For instance, omega-3 supplements boost the production of dopamine, which is an important chemical in the brain. Dopamine plays a role in memory, learning, attention, and emotions, and it also helps target hyperactivity .
Low levels of omega-3 fatty acids are even linked to an increased risk of developing various psychiatric disorders . This means that omega-3 supplements are a good alternative for improving mental health .
One study involved three months of omega-3 supplementation for a group of children with behavior, psychosocial, and learning difficulties. The children in the study demonstrated improvements in spelling, reading, behavior and demonstrated enhanced language development after consistently taking the supplements .
Omega-3 fatty acids were subsequently described as beneficial...
A recent clinical study showed that improving nutrient intake and the overall diet targets symptoms of autism spectrum disorder (ASD) such as anxiety, mood fluctuations, hyperactivity, aggression, and lack of focus, among others. The lead researcher, James Adams, PhD evaluated the effects of the following dietary intervention on ASD symptoms:
Day 0: Multivitamin/mineral supplementation
Day 30: Essential fatty acid (fish oil) supplementation
Day 60: Epsom salt baths
Day 90: Carnitine supplementation
Day 180: Digestive enzyme supplementation
Day 210: Healthy, gluten free, casein free, soy free diet
This particular type of intervention was chosen for several reasons. First, individuals with ASD tend to experience nutritional deficiencies that worsen ASD symptoms and overall health. Second, essential fatty acids (fish oil) support the health of cells throughout the body (e.g., brain, gastrointestinal tract), thereby targeting mental impairments and gastrointestinal problems that...
Nutrition Deficiencies and Autism
Children with autism are prone to having selective eating patterns, a limited food repertoire, sensory issues that are linked to restricted food intake, and neophobia, which refers to the fear of trying anything new including unknown or unfamiliar foods [1-3]. In some cases, dietary restrictions (e.g. casein- or gluten-free diets) that caretakers/parents use as a therapeutic approach to targeting behavioral and/or gastrointestinal issues may also contribute to the nutritional vulnerability of children with autism .
Accordingly, vitamin B-12, D, E, folate, biotin, and pantothenic acid deficiencies have been observed in individuals with autism as well as elevated vitamin B6 levels in some children with this condition . Children with autism also tend to have lower levels of calcium, magnesium, selenium, chromium, iodine, and lithium as well as amino acid and fatty acid imbalances . Over the years, research has demonstrated that these types of...
If your child only eats certain foods and often refuses to try new types of food, you may be wondering if your child is a picky eater or has a feeding problem. Here are a few ways to know the difference. Typically, the majority of children who are picky eaters and do not have a more serious feeding problem demonstrate a normal growth pattern . Normal growth and development as well as the absence of physical symptoms (e.g. trouble swallowing) are factors that healthcare professionals often look for when determining whether a child is a demonstrating picky eating or problem feeding .
Common signs of picky eating include [2-4]:
Feeding problems, on the other hand, may be due to...
