Although the focus has been on Covid this last year… there are still other health issues that have not gone away. Many are improved with simple treatments and dietary changes and in this series I am going to look at some of the more common issues.
I know that many of you who follow the blog will have seen the following post before but for those new to Smorgasbord, I hope you find useful.
Blood health- Anemia – Iron Deficiency and B12 Deficienc
There are a number of blood disorders that cause concern and one of the most common is Anaemia so I am going to focus on that today – with the foods and therefore the nutrients we require to support healthy blood in the next post.
What is Anaemia?
There are actually several types of Anaemia but whilst there are a number of reasons as you will see for the blood disorder, I will focus on just two.
Iron deficiency Anaemia and Pernicious Anaemia sometimes also known as Megaloblastic Anaemia. This anaemia is a Vitamin Deficiency anaemia and whilst requires medical supplementation of Vitamin B12 it can still be supported by a healthy diet.
Iron deficiency Anaemia is one of the most common types and is usually associated with women. Mostly in pregnancy, but it can also affect women who have suffered heavy periods throughout their reproductive lives. This puts post-menopausal women at risk of anaemia and if you suffer from the symptoms listed later on in the post, then I suggest you consult a doctor or at least begin a course of easy to digest iron supplementation. If your symptoms persist for more than a week or two then do get it checked out.
As the name implies this form of anaemia is caused by the lack of iron.
This might be because you have not taken in sufficient iron through your diet but it is also a vicious circle.
- The more blood you lose the more red blood cells you lose.
- These red blood cells release the iron when they die, and it is absorbed back into the system.
- If you sustain a lot of blood loss each month you will have increasingly less red blood cells which will lead to an iron deficiency over time.
Pregnant women lose their store of iron to the foetus, which is why many are put on an iron supplement although they can take in sufficient with an appropriate diet.
There are also other causes of blood loss, such as surgery or internal bleeding, but there are some diseases such as chronic bowel problems that induce a slow loss of blood over a long period of time and this can lead to Anaemia. If this is the case then you need to ensure that you visit your GP and ask for a blood test and do not take no for an answer.
Chronic tiredness which is a symptom of Anaemia always needs to be investigated.
In other posts in the health column, I have written about Candida Albicans, a parasite that robs nutrients from your food for its own use. This means iron too. As a result, part of the chronic fatigue associated with Candida can be linked to mild forms of anaemia. You can find out more here: Candida Albicans – Part One -The opportunistic pathogen
Iron Deficiency Anaemia
Of the two anaemias this one is wholly preventable and treatable with changes in diet and in some cases, supplementation.
The key to the diet is not just taking in iron in extra quantities and in fact it is not a good idea to suddenly rush off and grab yourself a bottle of iron tablets and start taking a handful as this can lead to chronic constipation. It is far better to start with adjusting your diet to include foods that are a good source of the mineral. ( I will be sharing the foods to include for healthy blood and to prevent iron deficiency in next week’s post.)
If you need additional supplementation then I do suggest fluid based formats and I use Spatone which has suspended iron in mineral water and it is easy on the stomach.
Pernicious Anaemia is actually a vitamin deficiency rather than an iron deficiency. As well as iron, your body needs B6, B12 and folic acid, or folate, to produce enough healthy red blood cells. If your diet is lacking in these, then you will have fewer red blood cells, and therefore less iron, and be anaemic. This is why it is very important that if you follow a Vegetarian and particularly a Vegan diet that you ensure that you are obtaining sufficient of these nutrients.
Who is the most likely to suffer from this type of anaemia?
Both men and women suffer from this type of anaemia. In rare cases it can be genetic or congenital when someone is born with the inability to absorb Vitamin B12 from their diet. In this case although a healthy diet will support the sufferer they have to be treated with injections of B12 or large doses orally for the rest of their lives.
Nutrition and blood diseases.
Diet plays an enormous part in the prevention and treatment of blood diseases. Today’s diet of processed foods, additives, chemicals and fad weight-loss plans are all contributing to the inability of our body to process the necessary and vital nutrients efficiently. I have worked with many people who decide that they are going to become vegetarian and have done so without finding appropriate substitutes for animal products that previously provided nutrients such as iron and the B vitamins. If you wish to become vegetarian then make sure that you are getting sufficient wholegrains, fermented soy products like miso or Tempeh and plenty of fresh fruit and green vegetables. There is plenty of advice online on how to change your diet safely so please take advantage of that.
In some anaemic patients it is the result of a disease or condition that prevents absorption of nutrients in general – such as Candida – Crohns disease or if someone is celiac. Anything that affects the small intestine will cause mal-absorption of nutrients and result in possible anaemia
Also, long-term medication, use of the pill, HRT and chemotherapy can have an effect on the way we absorb iron, B6, B12 and Folate. As I mentioned earlier, any blood-loss means that the iron that is normally recycled when cells die off naturally is not available. It is important that anyone who has been through an intensive a treatment for a disease such as cancer receives nutritional support afterwards to ensure that their diet is absolutely optimum for regaining healthy red blood cells.
What symptoms would someone experience if they were anaemic?
People will vary with the symptoms depending on the severity of the problem.
- Generally people will begin to feel very tired. As we have said the body is being deprived of one of its main energy sources – oxygen.
- Some may experience rapid heartbeats – perhaps find themselves getting breathless when they have not really over exerted themselves.
- There might be some chest pain associated with the symptoms – headaches or dizziness.
- Hands and feet can become numb and very cold.
- Nausea, causing loss of appetite and weight loss.
- Bleeding gums and a yellowish tinge to the skin and around the eyes.
What should you do if you feel that you might be anaemic?
If anyone is suffering from any of the symptoms above and is worried they should go and see their doctor and ask them to do a blood test. It would certainly either put their mind at rest or establish that there is a problem which can be easily treated – if necessary with a short term course of iron supplements or, if the problem is more serious, with injections.
For dietary based anaemia or where it is only a temporary problem with absorption of B12 – diet and supplementation might be appropriate.
If the problem is a long term issue, as with pernicious anaemia, then the treatment usually consists of injections – daily to begin with, for a week or so, until the condition as stabilised and then as required, which might be monthly or three-monthly. If B12 is given orally it requires much higher dosages to ensure absorption but there is currently experimentation with sublingual supplementation.
Both these types of anaemia can be supported with a healthy diet and next time a look at the nutrients that are needed to support the health of the red blood cells and the foods you need to obtain them.

Although I write a lot of fiction, I actually wrote my first two books on health, the first one, Size Matters, a weight loss programme 20 years ago, based on my own weight loss of 154lbs. My first clinic was in Ireland, the Cronin Diet Advisory Centre and my second book, Just Food for Health was written as my client’s workbook. Since then I have written a men’s health manual, and anti-aging programme, articles for magazines, radio programmes and posts here on Smorgasbord.
