Children with eczema: the link to food allergies is not clear cut

Food allergies eczema

Children’s allergy specialist, Dr Robert Boyle, unpicks the evidence behind the value of allergy tests for children with eczema.

Around one in five children have eczema – and even mild cases can have a big impact on both the child and their family. For many, symptoms will come and go before they start primary school, but for others it can indicate the beginning of a genetic tendency to develop allergic conditions such as hay fever or asthma (or both).

We also know that children with eczema are more likely to develop food allergies, especially if the condition starts in the first few months of life and is severe. Often parents will make the allergy diagnosis themselves – at the sudden onset of vomiting, diarrhoea or rash after eating scrambled egg, for example.

This can be frightening, but doctors can usually easily confirm the cause of these immediate reactions by talking to the parents and offering a confirmatory allergy blood or skin prick test.

In the absence of such obvious physical reactions however, a different question sometimes arises for parents: “Is a food allergy contributing to my child’s eczema and would an allergy test help to find out?” (more…)

Is mycoprotein an ideal food for managing blood sugar levels in Type 2 Diabetes?

For Diabetes Awareness Week, Anna Cherta-Murillo explains how mycoprotein, a food made of fungus, may hold the promise for managing blood sugar levels in Type 2 Diabetes.

If I were to ask you the first thing that comes to mind when you think of fungi, you would probably say mouldy walls, gone-off food, or athlete’s foot. The Fungi kingdom is often not viewed in a positive light. However, we owe a lot to fungi; they produce life-saving antibiotics, have allowed organ transplantations in humans and can recycle many types of waste. In the area of nutrition, some fungi also have the potential to affect human health in a beneficial way, although little research has been devoted to it compared to other foods. In the Nutrition Section of the Department of Medicine at Imperial, we are putting fungi into the limelight and studying the impact of a particular type of fungus on blood sugar levels and appetite in South Asian and European people with Type 2 Diabetes (T2D).

The problem

1 out of 20 people worldwide has T2D, with South Asians being more prone to the disease compared to Europeans (Figure 1). People with T2D have higher blood sugar levels than normal, which over time can increase the chances of developing long-term complications such as blindness, kidney disease and heart failure. It is therefore important to manage blood sugar levels in people with T2D in order to keep blood sugar in the normal range. The first-line strategy to achieve this is by improving dietary intake. Healthy, balanced diets are generally characterised as being high in dietary fibre and protein, which decrease both blood sugar levels and appetite. If blood sugar levels are reduced toward normal levels, the chances of having T2D-related complications are reduced. Likewise, if appetite is decreased, intake of energy-rich foods will likely also decrease, helping to reduce body weight, which is a key risk factor for T2D. However, an ongoing problem with healthy diets is that they are not suitable for all cultures and most of the research around them has been conducted in people of European origin, therefore not being applicable to South Asians. Furthermore, people often find it difficult to stick to these diets. (more…)

Could the EndoBarrier be the next weapon of mass reduction?

Endobarrier

In this post, Dr Aruchuna Mohanaruban tackles the most asked questions about the EndoBarrier – a medical device for the treatment of type 2 diabetes and obesity.

UK obesity rates have continued to rise at an alarming rate, with figures higher than any other developed nation. Strongly associated with obesity is the increased susceptibility to developing type 2 diabetes (T2DM) which currently affects 3.2 million of the UK population. Bariatric surgery – a type of surgery aimed at inducing weight loss – usually by altering the stomach and/or intestines has revolutionised the treatment of these conditions and can lead to a 60% remission in diabetes. However, with demand for this type of surgery outstripping supply, there is a greater need to develop non-surgical alternatives to combat the ever-rising obesity and diabetes epidemic. (more…)

Festive feasting: the good, the bad and the microbiome

Microbiome

In this festive post, Dr Anjali Amin looks at how to keep our gut microbiome happy over this period of indulgence.

As the festive season approaches, one wonders how our bodies prepare for the enormity of food that will be ingested in a relatively short space of time.  In the UK alone, the average person consumes 7000 calories on Christmas Day alone.  This is three times the recommended calorie intake per day, and most of us will have reached the recommended calorie intake before Christmas lunch has even been served. And of course, it’s not just about eating more. We are also a great deal more sedentary, with the average person in the UK spending 5.5 hours a day in front of the television over the Christmas period desperately awaiting reruns of Blackadder and yet another Christmas special!

Weighing up dodgy diets

Weighing up dodgy diets

From gluten-free to detox diets, Dr Anusha Seneviratne dissects the scientific evidence (or lack of) behind eccentric diets. 

Magazines and newspapers are full of so-called ‘tips’ or ‘advice’ for the image conscious, detailing extreme diets followed by the rich and famous to achieve dramatic weight loss, or new diets apparently supported by the latest scientific research. One example is the gluten-free diet, made fashionable particularly in the sporting world by former world number one tennis player Novak Djokovic (1). Having had a reputation for being physically weaker than his rivals, Djokovic was eventually diagnosed with coeliac disease and the resulting gluten intolerance. Eliminating gluten from his diet transformed his career. (more…)
