Medical researchers have long asked the question: Is there a connection between one’s blood type and autoimmune disease?
Clinical studies have had varied results, mostly due to the small sample sizes of each study. Though this area needs more research, this blog post will cover some of the research that has been published so far.
The researchers assessed 823 patients, with the following distribution of blood types: 42.5% patients had type A blood, 33.2% had type O blood, 15.4% had type B, and 8.9% had type AB. Each patient in the study had at least one of the following nine rheumatic diseases:
Familial Mediterranean fever (FMF)
Rheumatoid arthritis (RA)
Systemic lupus erythematosus (SLE)
Systemic sclerosis (SSc)
Sjogren’s syndrome (SjS)
Undifferentiated connective tissue disease
Their study found that there was a significant difference in the distribution of blood types among those with rheumatic diseases. The most common autoimmune diseases among those with type A blood were: rheumatoid arthritis, spondyloarthropathy, vasculitis, Behçet’s disease, and undifferentiated connective tissue disease.
The most common autoimmune diseases among those with type O blood were: systemic lupus erythematosus, systemic sclerosis, and Sjogren’s syndrome. The researchers also noted that SLE, SSc and SjS are the connective tissue disorders frequently observed with antinuclear antibodies (ANA). The rheumatic disease familial Mediterranean fever was also found to be most common in those with type O blood.
Those with blood type AB were observed to be the least likely to suffer from rheumatic disease. However, it should be noted that type AB blood is also the most rare blood type in general, and represented the smallest amount of patients studied.
In addition, it was found that there was a significant difference in the distribution of Rh factor in rheumatic diseases. Of those with rheumatic diseases, 92.2% patients were Rh positive and only 7.8% patients were Rh negative. However, it should once again be noted that a positive Rhesus Factor (Rh+) is also more common among the general population than a negative Rhesus Factor (Rh-).
Is there a link between autoimmune disease and blood type?
So, if you have blood types A or O, does this mean you are more likely to get an autoimmune disease? The researchers who conducted this study concluded: “…we believe that the higher incidence of different rheumatic diseases in different blood types is associated with different genetic predispositions.”
In other words, since blood type is inherited (i.e. genetic), the results of the study point to a likely connection between certain genes and the increased predisposition for developing an autoimmune or rheumatic disease.
Do you know your blood type?
I, for one, do not know my own blood type. This is somewhat ironic, since I’ve undergone many blood tests as part of my Sjogren’s syndrome diagnosis, as well as for monitoring my liver enzyme levels while taking certain medications to control my autoimmune symptoms.
I actually did ask my primary care doctor what my blood type was the last time he ordered a test, and he advised that finding out your blood type is not a common part of the blood testing routine, and thus, he didn’t know what mine was.
If you have an autoimmune disease (or multiple diseases), and you know your blood type, comment below and let us know, are your condition and blood type consistent with the results of this study?
Carrie Ann Inaba, TV host on CBS’ The Talk and judge on ABC’s hit show Dancing with the Stars opened up about her struggle living with autoimmune diseases and chronic illnesses on her blog, Carrie Ann Conversations.
The Emmy award-nominated TV personality said that she has been diagnosed with several different autoimmune diseases and chronic conditions over the years, including Sjogren’s Syndrome, Systemic Lupus Erythematosus (SLE) and Rheumatoid Arthritis (RA), and she also has the markers for Antiphospholipid Syndrome (APS), which causes blood clots. The 53-year-old dancer and choreographer says she also struggles with fibromyalgia and spinal stenosis.
As a result of her various autoimmune conditions, Inaba has taken a leave of absence from her role on The Talk so that she can focus on her health, reports MedPage Today.
Talking about her health journey, Inaba said: “Even if we are fortunate enough to get a diagnosis, we can quickly end up with more questions than answers. Often when it comes to autoimmune conditions there is no perfect solution or clear path forward.”
Inaba continued, explaining: “Coping with autoimmune conditions can sometimes feel quite lonely. When I first got diagnosed, some encouraged me to keep my struggles to myself, but I’ve found that it’s always been better to be honest about my needs and realities than to stay silent. I believe strongly in sharing my journey, my solutions, and the things that have helped me.”
In this spirit, Inaba has shared on her blog the products that have helped her cope with her autoimmune disease symptoms – including eye dryness, mouth dryness, joint pain, fatigue, brain fog and more – so that others can benefit from these products and see if they work for them.
This isn’t the first time that Carrie Ann Inaba has opened up about her health struggles. The starlet previously posted on Instagram about how she felt ashamed of her autoimmune diseases, and wanting “…to be what people see. And people see a healthy person, from the outside.” However, confronting her health problems made Inaba reflect on who she is as a person, besides just her identity as a “sexy dancer chick.”
From all of us at Autoimmune Warrior, we want to thank Carrie Ann for opening up about her health journey as an #AutoimmuneWarrior, and raising awareness about the 80+ autoimmune diseases affecting over 23 million Americans. Because of celebrities like her, more people among the general population are learning about autoimmune conditions, and why extensive research is needed to find better treatments, and eventually, a cure.
According to the US National Library of Medicine, inflammation is your body’s normal physiological defense against pathogen infection. In normal circumstances, the inflammatory process ends quickly; but, with many chronic conditions, the immune system’s response continues well after an infection is present, leading to significant tissue and organ damage. This is the case with many autoimmune diseases, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), type 1 diabetes, and more.
Many autoimmune disease patients are forced to turn to pharmaceutical drugs to calm their overactive immune systems. Unfortunately, many of these immunosuppressant drugs are not without significant side effects. Plus, by decreasing your body’s ability to fight infections, patients may find that they’re vulnerable to bacteria and viruses, something that’s especially of concern now during the COVID-19 pandemic.
But, what if there was a way to fight inflammation naturally, without having to turn to prescription medications with difficult side effects? According to Harvard Health Publishing, some of the best anti-inflammatory compounds can be found not in your local pharmacy, but in the grocery aisle.
“Many experimental studies have shown that components of foods or beverages may have anti-inflammatory effects,” explains Dr. Frank Hu, Professor of Nutrition and Epidemiology at Harvard’s School of Public Health. Anti-inflammatory food also helps individuals to maintain a healthy weight – something important, since weight gain is a risk factor for inflammation. However, even when studies controlled for obesity, the effects of inflammation remained: “Some of the food components or ingredients may have independent effects on inflammation over and above increased caloric intake,” Dr. Hu says.
So, what are these anti-inflammatory foods that you can grow at home? Check out the full list, below!
Tomatoes were first on Harvard Health Publishing‘s list of anti-inflammatory foods. According to Healthline, tomatoes are an excellent source of lycopene, an antioxidant with anti-inflammatory properties. Studies have also shown that lycopene may be beneficial for reducing pro-inflammatory compounds related to several types of cancer. Another study found that women with excess weight who drank tomato juice significantly decreased their inflammatory markers.
Tomatoes are also some of the easiest plants to grow. I grew up in Southwestern Canada, an area that isn’t exactly known for warm weather or sunshine. Despite the climate, our family was able to easily grow cherry tomatoes on our small, north-facing balcony during the spring and summer. Now that I live in Southern California, tomatoes grow even more abundantly, and we’re growing both cherry and heirloom varieties.
Pro tip- if you’re looking to increase lycopene absorption, consider cooking your tomatoes in olive oil. This is because lycopene is a carotenoid, which is a nutrient that is better absorbed in combination with a fat.
This leads us to the next item on our list…
Olives are rich in monounsaturated fats, which are heart-healthy fats that combat damaging inflammation. It’s no wonder then, that olives and olive oil are staples in the mediterranean diet, a healthy eating lifestyle followed by many supercentenarian communities.
Olives and olive oil also contain oleocanthal, an antioxidant that has been compared by scientists to ibuprofen, the nonsteroidal anti-inflammatory drug (NSAID) commonly taken to combat pain and inflammation. Extra virgin olive oil has even more anti-inflammatory benefits compared to more refined types of olive oil.
Olive trees grow best in a subtropical, mediterranean climate in which winters are mild and summers are long, dry and warm. The best climate for olive trees would be zones 10 and 11, though certain varieties of olive trees can tolerate zones 8 or 9. Then, once you’ve grown olives, you can use an oil press machine to extract the oils from the pitted fruit. We live in zone 10a and are currently growing an olea europaea, which is the European variety.
Of course, if you don’t live in an ideal climate for growing olives, then not to worry – olives and extra virgin olive oil are commonly found in grocery stores all over the world.
3. Leafy Greens
Green, leafy vegetables are next up on the list. Spinach, kale and collard greens are all easy-to-grow vegetables that possess powerful, anti-inflammatory properties. According to the Arthritis Foundation, these vegetables are high in vitamins like A, C and K which protect your cells against damaging free radicals. They are also high in calcium, which helps promote bone health.
In our garden, we’re currently growing spinach and red chard. Not only do these vegetables grow extremely fast, they also are quite hardy across different climates, and produce an abundant, constant harvest. Plus, leafy greens aren’t just for salads – you can throw them in your smoothie or protein shake, in soups and stews, stirfries, and even scramble them up with eggs. The possibilities are endless!
3. Cruciferous Vegetables
Cruciferous veggies include broccoli, cauliflower, cabbage, brussels sprouts, radishes, rutabaga, turnips, kohlrabi, watercress and bok choy. These vegetables have many of the vitamins and minerals found in other leafy greens, plus the added benefit of a phytochemical called sulphoraphane, which has been shown to block the inflammatory process, and may slow cartilage damage in osteoarthritis (OA), according to studies done on mice.
In lab studies, sulphoraphane has also been shown to stimulate enzymes in the body that detoxify carcinogens before they can damage one’s cells. Two other compounds found in cruciferous vegetables called indole 3-carbinol and crambene are also believed to activate detoxifying enzymes.
Cruciferous vegetables belong to the brassica family, and are best suited to regions with mild summers, cool springs and fall temperatures. This means that you don’t have to live in a tropical or subtropical area to be able to grow these anti-inflammatory foods.
Berries contain antioxidants called anthocyanins, which are compounds that have anti-inflammatory effects and may reduce your risk of disease. Studies have shown that people who ate berries consistently had lower levels of certain inflammatory markers in their blood. Other studies have shown that individuals who consume berries also had higher levels of natural killer (NK) cells that kept their immune system functioning properly.
Though many different varieties of berries exist, the most common are strawberries, raspberries, blueberries and blackberries. While many berry varieties are native to the wet Pacific Northwest, berries like strawberries can be successfully grown in drier climates like California and Mexico when given enough water. Here in Southern California, we have been able to successfully grow both strawberries and blueberries during the wetter winter months, and recently planted raspberry and blackberry bushes as well.
Mushrooms contain a property called phenols, which have been shown to provide protection against damaging inflammation. Other anti-inflammatory properties found in mushrooms include polysaccharides, terpenoids, phenolic compounds, and many other low molecular weight molecules. Lion’s mane mushrooms have also been found to reduce low-grade, chronic inflammation linked to metabolic disorders like obesity. Thanks to its healing properties, fungi has often been used in traditional medicine across different parts of Asia and Africa.
Some easy-to-cook mushroom varieties include white button, crimini, portabella, oyster, lion’s mane, shiitake, morels and truffles. Though you may be thinking, ‘how can I grow mushrooms in my home garden?’ It’s actually easier than you think! We have used a mushroom grow kit from Back to the Roots to grow both oyster mushrooms and lion’s mane mushrooms at home in as little as two weeks!
Grapes, like berries, also contain high levels of anthocyanins, which have anti-inflammatory effects. Consumption of grapes has been shown to reduce the risk of many conditions, including diabetes, heart disease, Alzheimer’s, and eye disorders. Grapes are also a staple in the mediterranean diet, as well as moderate levels of heart-healthy red wine. In fact, cannonau red wine has touted for its antioxidant benefits by supercentenarian researchers in the blue zones of Italy and Greece, due to its artery-scrubbing flavonoids.
Grapevines grow best in areas with long, warm summers and rainy winters. This is why only certain parts of the world are known for producing the best grapes for wine-making: the Bordeaux region of France, Tuscany, Italy, the Napa Valley in California, La Rioja in Spain, the Colchuaga Valley in Chile, and the Okanagan Valley in British Columbia, Canada. While I don’t anticipate that we’ll be making any wine at home, we are growing both a red and green grapevine in our California garden, and so far, both have taken off quite well.
Last but certainly not least, turmeric is one of the best plants to combat inflammation. This is because turmeric contains a property called curcumin, a powerful, anti-inflammatory nutrient found to help those suffering from arthritis, diabetes, and other conditions causing joint pain.
Turmeric resembles a root vegetable, and once harvested, it can be dried out and ground to make a spice. Turmeric is commonly used in South Asian and Middle Eastern cuisines. Being part East Indian myself, I know that it’s a staple in Indian curries, as well as in Ayurvedic medicine, which has been practiced for thousands of years in India.
However, many individuals with joint pain opt to take curcumin supplements, rather than grow turmeric at home or buying the spice at the grocery store. This is because it can be challenging to get enough curcumin through eating turmeric, unless you consume a lot of it. Plus, curcumin has been found to be more easily absorbed when taken in combination with piperine, a compound found in black pepper. So the benefit of taking a curcumin supplement is that it often has piperine added to aid absorption.
