Seasonal Allergies and Probiotics

As spring approaches, you may find yourself dreading the sniffles, sneezes, and watery eyes that come with the season. Yet another link between allergies and the microbiome — The American Microbiome Institute. Dogs, Dust Microbes, and Allergies. WIKIMEDIA, BEV SYKESA pet dog can bring joy, companionship, and security to a home.

Dogs, Dust Microbes, and Allergies

It could also change the microbes in your gut. Susan Lynch from the University of California, San Francisco, has shown that cohabitating with a dog can increase the diversity of bacteria in house dust. When she fed this bacteria-rich dust to mice, it shifted the microbes in their guts towards species that prevented their immune systems from overreacting to airborne allergens. The team also showed that a single bacterial species could duplicate many of these benefits.

The results are published today (December 16) in PNAS. Dogs are the worst enemy of asthma and childhood allergies. Bacterial exposures necessary for decreasing risk of allergy. Observational studies in humans have shown that early life exposure to microbes in a variety of situations is associated with a decreased risk of asthma.

Bacterial exposures necessary for decreasing risk of allergy

These include: – Exposure of a pregnant mother to microbes in order to protect her baby – Exposure of children to livestock or dogs – Growing up with numerous siblings Meanwhile, disruption of normal colonization processes (such as antibiotic use and C-section delivery) is associated with an increased risk of allergy. Some gut microbiota changes also track with asthma risk. For example, one study showed a greater risk of developing childhood allergic diseases when infant feces contained higher levels of Escherichia coli or Clostridium difficile. Whereas observational studies don’t tell us about causality, mouse models can be useful first steps for identifying causal links. A recent mouse study delved more deeply into how microbial exposures were associated with allergic immune responses. The next step: to confirm these findings in humans.

Food Allergies Linked To Overactive Immune System At Birth. One in every ten babies in Melbourne develops a food allergy during their first year of life.

Food Allergies Linked To Overactive Immune System At Birth

New research has found children who are born with overly active immune cells are more likely to develop allergies to milk, eggs, peanuts, wheat and other common foods. This finding could lead to future treatments for babies to prevent childhood food allergies. Treating severe nickel allergies with probiotics — The American Microbiome Institute. Systematic nickel allergy syndrome (SNAS) is a severe reaction to nickel, a metal that is found in nature and most human food sources.

Eczema & Probiotics: Personal Update, Reader Reports, and the Respiratory Connection

Why is that good news? Because I stopped taking the probiotic a week and a half ago. Eczema & L. Plantarum Success Stories. Thought I’d do a roundup of some of the reader reports that popped up throughout the past month… After not achieving any success with the standard dermatological approaches, Mary has cleared up her eczema completely using the L. plantarum probiotic: Thank you for the advice on taking probiotics for eczema.

Respect the microbiota. A study on the effects of prebiotics on satiety and hunger came across my radar the other day.

Respect the microbiota.

It had an interesting finding — that increased fiber had opposite satiety effects in men and women: Over the remainder of the day, the high dose of scFOS reduced food intake in women, but increased food intake in men, suggesting a gender difference in the longer-term response. I filed it away as interesting. Do women somehow extract more energy from fiber than men? Maybe. The Truth About “Lactose Intolerance” I’ve wanted to address this one for a while.

Mimi L. K. Gut microbiota protect against peanut allergen sensitization. Dietary fibre/short-chain fatty acids and vitamin A may protect mice against peanut allergy via gut microbiota - Gut Microbiota for Health. The incidence of food allergies has increased dramatically in western countries over the past 20 years and the gut microbiota seems to be a promising target for preventing and treating them. However, mechanisms by which gut microbiota is involved in the loss of oral tolerance remain unclear. The researchers examined the beneficial roles of dietary fibre in peanut allergy using mice. Mice were fed on diets either depleted or enriched in fibre for at least 2 weeks. High-fibre feeding enhanced the activity of mucosal CD103+ dendritic cells (DCs), which are the main regulators of immune tolerance through promoting the differentiation of naïve T cells into regulatory T (Treg) cells in the mesenteric lymph nodes (MLN).

The fibre achieved this effect by upregulating retinoic acid-synthesizing (RALDH) enzyme activity and enhancing antigen-specific Treg cell responses. Cooling Inflammation: Preventing Allergies. The cause of allergies and autoimmune degenerative diseases is inflammation. As a scientist, I am concerned with how the body works at the molecular level. I try to understand how molecules of cells interact to cause disease. Cooling Inflammation: Allergy, Asthma, Autoimmunity Start the Same Way. Inflammation is the current medical buzzword.

Name the disease and inflammation is there. Cooling Inflammation: Helminths, Oligosaccharides and Immunotolerance. Parasitic worms reverse allergies and autoimmune diseases using oligosaccharides to mimic self and silence immune over-responsiveness. Health Diagrams II — Curing Autoimmunity and Allergies. Diet high in fiber and vitamin A key to preventing allergies to peanuts and other triggers. Eating a diet rich in fibre can actually shape the immune system to reduce allergies to substances such as peanuts, new research shows.
