![]() In March this year, researchers from the 𝘈𝘶𝘴𝘵𝘳𝘢𝘭𝘪𝘢𝘯 𝘕𝘢𝘵𝘪𝘰𝘯𝘢𝘭 𝘜𝘯𝘪𝘷𝘦𝘳𝘴𝘪𝘵𝘺 made a fantastic discovery. They realised that a protein we produce in our bodies significantly influences our immune system’s reaction to allergens. People who produce less amount of Neuritin have a higher risk of dying of 𝐀𝐧𝐚𝐩𝐡𝐲𝐥𝐚𝐱𝐢𝐬 and developing 𝐚𝐥𝐥𝐞𝐫𝐠𝐢𝐞𝐬. Studies in mice showed some key components that mediate allergic reactions were substantially raised in mice lacking Neuritin. They proceeded to give Neuritin to those mice, and it managed to restore the lost function, decreasing the production of 𝐈𝐠𝐄 and other 𝐚𝐧𝐭𝐢𝐛𝐨𝐝𝐢𝐞𝐬. To make matters more important, it was also found that Neuritin also plays a vital role in decreasing 𝐚𝐮𝐭𝐨-𝐢𝐦𝐦𝐮𝐧𝐞 𝐝𝐢𝐬𝐞𝐚𝐬𝐞, 𝐚𝐬𝐭𝐡𝐦𝐚 and the control of 𝐜𝐚𝐧𝐜𝐞𝐫 cells. This means we might have a chance to introduce a protein our body produces and give it to patients who are deficient in it, helping them either outgrow their 𝐚𝐥𝐥𝐞𝐫𝐠𝐢𝐞𝐬 and 𝐚𝐬𝐭𝐡𝐦𝐚 or decrease the severity of the symptoms. www.facebook.com/permalink.php?story_fbid=253986310061921&id=100063516604410

![]() Often people ask me what they should do when they see a "𝘮𝘢𝘺 𝘤𝘰𝘯𝘵𝘢𝘪𝘯" label. My first question to them is, how many variations of that wording have they seen?
𝐒𝐨 𝐭𝐡𝐚𝐭 𝐲𝐨𝐮 𝐤𝐧𝐨𝐰, 𝐚𝐥𝐥 𝐯𝐚𝐫𝐢𝐚𝐭𝐢𝐨𝐧𝐬 𝐦𝐞𝐚𝐧 𝐞𝐱𝐚𝐜𝐭𝐥𝐲 𝐭𝐡𝐞 𝐬𝐚𝐦𝐞. Several other studies went to see what was the actual variation of allergen concentration. What did they find?
In reality, there is still a significant risk of a not labelled food, to contain a substantial amount of allergens. But why is it that the food industry has this massive variability in warnings they use and still have so much potential cross-contamination of allergens? The problem tracks back to political parties, the way they are funded or the individual politician's financial interest. What I am saying might be controversial, but let's look at what is known. Most of you have never heard of the "𝘌𝘶𝘳𝘰𝘱𝘦𝘢𝘯 𝘍𝘰𝘰𝘥 𝘍𝘰𝘳𝘶𝘮".
In the 𝘜𝘚𝘈 alone, in the 2014 elections, the food industry donated $𝟏𝟕𝐌, in total, to both parties. This comes to the 𝐏'𝐬 I have spoken about before. Those, also called 𝐄𝐃'𝐬 (𝘌𝘭𝘪𝘤𝘪𝘵𝘪𝘯𝘨 𝘋𝘰𝘴𝘦), look into the dose needed to cause an allergic reaction and the percentage of allergic people who will react. So a 𝐏𝟏 or 𝐄𝐃𝟏 means that the potential cross-contamination in a particular food will lead to 1% or fewer allergic people reacting to that food. The best collaboration done so far is the one between the food industry in Australia, the Government and Allergy Organizations. (see the attached table to see the ED for the 14 main allergens) Such an agreement does not exist in the 𝘌𝘜 at present. The hope for the 𝘜𝘒, at the moment, is that the so called "𝐍𝐚𝐭𝐚𝐬𝐡𝐚'𝐬 𝐋𝐚𝐰" will lead to a change in this practice. But we need to go deeper than simple labelling, look into manufacturing practices, and avoid allergens altogether. www.facebook.com/permalink.php?story_fbid=218423533618199&id=100063516604410 ![]() Also known as Retinol or Retinoic Acid.
It was the first 𝘧𝘢𝘵-𝘴𝘰𝘭𝘶𝘣𝘭𝘦 but not the first Vitamin to be discovered. It all started with the 𝘌𝘨𝘺𝘱𝘵𝘪𝘢𝘯𝘴, as they found that some types of 𝘣𝘭𝘪𝘯𝘥𝘯𝘦𝘴𝘴 could be cured by 𝘦𝘢𝘵𝘪𝘯𝘨 𝘭𝘪𝘷𝘦𝘳. This Vitamin plays a vital role in 𝘷𝘪𝘴𝘪𝘰𝘯, 𝘨𝘳𝘰𝘸𝘵𝘩, 𝘤𝘦𝘭𝘭 𝘥𝘪𝘷𝘪𝘴𝘪𝘰𝘯 and 𝘪𝘯𝘵𝘦𝘨𝘳𝘪𝘵𝘺 (mainly 𝘢𝘪𝘳𝘸𝘢𝘺𝘴, 𝘶𝘳𝘪𝘯𝘢𝘳𝘺 𝘵𝘳𝘢𝘤𝘵 and 𝘨𝘶𝘵), 𝘳𝘦𝘱𝘳𝘰𝘥𝘶𝘤𝘵𝘪𝘰𝘯 and 𝘪𝘮𝘮𝘶𝘯𝘪𝘵𝘺. We cannot forget how important it is for foetal development. But beware, pregnant women DO NOT need a Vitamin A dose higher than the daily recommended dose. Due to this, many believe it is 𝐭𝐡𝐞 𝐦𝐨𝐬𝐭 𝐞𝐬𝐬𝐞𝐧𝐭𝐢𝐚𝐥 𝐕𝐢𝐭𝐚𝐦𝐢𝐧 in animal life (not just humans). When there is a deficiency, it can lead to:

The definition of 𝐀𝐧𝐚𝐩𝐡𝐲𝐥𝐚𝐱𝐢𝐬 is not uniform worldwide. For you to have an idea, the WAO (𝘞𝘰𝘳𝘭𝘥 𝘈𝘭𝘭𝘦𝘳𝘨𝘺 𝘖𝘳𝘨𝘢𝘯𝘪𝘻𝘢𝘵𝘪𝘰𝘯), the WHO (𝘞𝘰𝘳𝘭𝘥 𝘏𝘦𝘢𝘭𝘵𝘩 𝘖𝘳𝘨𝘢𝘯𝘪𝘻𝘢𝘵𝘪𝘰𝘯), the AAAAI (𝘈𝘮𝘦𝘳𝘪𝘤𝘢𝘯 𝘈𝘤𝘢𝘥𝘦𝘮𝘺 𝘰𝘧 𝘈𝘭𝘭𝘦𝘳𝘨𝘺, 𝘈𝘴𝘵𝘩𝘮𝘢 𝘢𝘯𝘥 𝘐𝘮𝘮𝘶𝘯𝘰𝘭𝘰𝘨𝘺), the EAACI (𝘌𝘶𝘳𝘰𝘱𝘦𝘢𝘯 𝘈𝘤𝘢𝘥𝘦𝘮𝘺 𝘰𝘧 𝘈𝘭𝘭𝘦𝘳𝘨𝘺 𝘢𝘯𝘥 𝘊𝘭𝘪𝘯𝘪𝘤𝘢𝘭 𝘐𝘮𝘮𝘶𝘯𝘰𝘭𝘰𝘨𝘺) and the ASCIA (𝘈𝘶𝘴𝘵𝘳𝘢𝘭𝘢𝘴𝘪𝘢𝘯 𝘚𝘰𝘤𝘪𝘦𝘵𝘺 𝘰𝘧 𝘊𝘭𝘪𝘯𝘪𝘤𝘢𝘭 𝘐𝘮𝘮𝘶𝘯𝘰𝘭𝘰𝘨𝘺 𝘢𝘯𝘥 𝘈𝘭𝘭𝘦𝘳𝘨𝘺), all have slightly different definitions. The one I like the most is actually the ASCIA one: "𝘈 𝘳𝘢𝘱𝘪𝘥𝘭𝘺 𝘦𝘷𝘰𝘭𝘷𝘪𝘯𝘨, 𝘨𝘦𝘯𝘦𝘳𝘢𝘭𝘪𝘴𝘦𝘥 𝘮𝘶𝘭𝘵𝘪-𝘴𝘺𝘴𝘵𝘦𝘮 𝘳𝘦𝘢𝘤𝘵𝘪𝘰𝘯 𝘤𝘩𝘢𝘳𝘢𝘤𝘵𝘦𝘳𝘪𝘴𝘦𝘥 𝘣𝘺 𝘰𝘯𝘦 𝘰𝘳 𝘮𝘰𝘳𝘦 𝘴𝘺𝘮𝘱𝘵𝘰𝘮𝘴 𝘰𝘳 𝘴𝘪𝘨𝘯𝘴 𝘰𝘧 𝘳𝘦𝘴𝘱𝘪𝘳𝘢𝘵𝘰𝘳𝘺, 𝘤𝘢𝘳𝘥𝘪𝘰𝘷𝘢𝘴𝘤𝘶𝘭𝘢𝘳 𝘢𝘯𝘥 𝘰𝘵𝘩𝘦𝘳 𝘴𝘺𝘴𝘵𝘦𝘮𝘴 𝘴𝘶𝘤𝘩 𝘢𝘴 𝘵𝘩𝘦 𝘴𝘬𝘪𝘯 𝘢𝘯𝘥/𝘰𝘳 𝘎𝘐 𝘵𝘳𝘢𝘤𝘵." Given this, how do we know it is 𝐀𝐧𝐚𝐩𝐡𝐲𝐥𝐚𝐱𝐢𝐬 or not Have a look at the image above. What to do if you think you, or your child, are having an anaphylactic reaction?
It is important to know that 𝐀𝐧𝐚𝐩𝐡𝐲𝐥𝐚𝐱𝐢𝐬 is a 𝐫𝐚𝐫𝐞 𝐞𝐯𝐞𝐧𝐭, and most times, it 𝐃𝐎𝐄𝐒 𝐍𝐎𝐓 𝐥𝐞𝐚𝐝 𝐭𝐨 𝐝𝐞𝐚𝐭𝐡. In fact, recently published research said there had been a significant increase in hospital admissions with Anaphylaxis, but a decrease in deaths. This seems like a contradiction, but it is not. Why is that?
I will put my hands down, and agree with whoever tells me what is done, is still not enough. The bottom line is:

The best course of action to deal with eczema, and potentially prevent the development of allergies, should be:
(In due course, I will publish more information regarding eczema and the best way to take care of it.)

Though this study was not done in the UK, I would suggest parents need to be aware of the possibility of the same happening in summer camps here or any other country where they might send their children to. The main lessons to take from this study are:
As more and more nurseries/schools are becoming nuts free, it would not be a bad idea for summer camps to follow suit.

The substance that causes such a reaction is called an "allergen". Allergens can be found all around us.
The primary reaction that will happen is the immune system trying to destroy that "invader" (allergen), and for that, it uses a significant amount of the immune mediators. The outcome is an allergic reaction that can come in all sorts of presentations and severity. Saying that not all allergens we get in contact with will make our immune system react. Some are relatively harmless, depending on each individual's immune system and, often, prior exposure to that substance. What are the most common allergens in children?
How does it affect children:
The outcome of the allergies depends on the food the child is allergic to.
Milk, soy, egg and wheat - are the most common foods involved in non-IgE mediated food allergy. www.facebook.com/permalink.php?story_fbid=255082522988655&id=109164090913833 |
