If you're searching for foods to avoid with ITP, you've probably seen lists telling you to eliminate garlic, ginger, turmeric, blueberries, and other healthy foods. While these recommendations are often well-intentioned, the scientific evidence is more nuanced than many people realize. Understanding the difference between platelet count and platelet function can help you make informed decisions without unnecessary fear. Many ITP warriors have been taught to avoid these foods out of fear that they may "thin the blood" or "lower platelets,"
But is the fear justified?
The answer is more complex than a simple yes or no.
Let's look at what the research actually says.
Understanding Platelet Count vs. Platelet Function
Before discussing individual foods, it's important to understand one of the biggest misconceptions in the ITP community.
Platelet count and platelet function are not the same thing.
- Platelet count refers to how many platelets are circulating in your blood.
- Platelet function, also called "aggregation", refers to how well those platelets stick together to form a clot when needed.
Some foods have demonstrated mild effects on platelet aggregation (how sticky platelets are) in laboratory studies. That does not necessarily mean they lower platelet counts.
Most of the research often cited online involves laboratory experiments, animal studies, or concentrated supplements—not people with ITP eating normal amounts of these foods as part of a healthy diet.
That distinction matters.
Are Blueberries Bad for ITP?
Blueberries are sometimes criticized because they naturally contain salicylates and powerful plant compounds called polyphenols. Some laboratory studies suggest these compounds may have mild anti-platelet activity. However, blueberries are also one of the richest sources of anthocyanins—antioxidants known to reduce oxidative stress and inflammation.
For people living with autoimmune conditions, reducing chronic inflammation may be far more beneficial than worrying about a mild laboratory effect on platelet aggregation.
There is currently no strong clinical evidence that eating normal servings of blueberries lowers platelet counts in people with ITP.
Is Turmeric Safe for People with Low Platelets?
Turmeric is probably one of the most misunderstood spices in the autoimmune world. Curcumin, the active compound in turmeric, has demonstrated anti-inflammatory and mild anti-platelet effects in laboratory studies. High-dose curcumin supplements may also interact with blood-thinning medications. However, there's an important difference between using turmeric as a cooking spice and taking several grams of concentrated curcumin every day.
Most of the studies showing anti-platelet effects use purified extracts at doses far beyond what someone would consume in food. Meanwhile, turmeric is well known for supporting healthy inflammatory pathways and providing powerful antioxidant benefits.
Does Ginger Lower Platelets?
Ginger has been used for centuries in both cooking and traditional herbal medicine. Like turmeric, ginger has demonstrated mild anti-platelet effects in some studies, particularly when used in concentrated extracts or large supplemental doses.
Fresh ginger used in tea, soups, stir-fries, or other recipes provides far lower amounts. Ginger also offers numerous health benefits, including supporting digestion, reducing nausea, promoting healthy blood sugar regulation, and helping reduce inflammation.
For many people, those benefits outweigh theoretical concerns associated with normal culinary use.
Should People with ITP Avoid Garlic?
Garlic may be the food that creates the most fear within the ITP community. Garlic contains sulfur compounds such as allicin that may reduce platelet aggregation. Again, reducing platelet aggregation is not the same as lowering platelet count.
Garlic is also associated with cardiovascular health, immune support, antimicrobial properties, and anti-inflammatory effects. Most concerns involve garlic supplements or consuming unusually large quantities—not using garlic to season everyday meals.
The Bigger Picture: Don't Let Fear Replace Nutrition
One of the biggest mistakes I see is people becoming so focused on avoiding a few healthy foods that they overlook the foods most likely to contribute to chronic inflammation.
In my opinion, I'd be much more concerned about regularly consuming:
- Ultra-processed foods
- Refined sugars
- Highly processed carbohydrates
- Industrial seed oils (especially repeatedly heated oils)
- Artificial food additives
- Excess alcohol
These foods are much more consistently associated with increased inflammation, oxidative stress, and metabolic dysfunction.
Meanwhile, whole foods like berries, leafy greens, herbs, spices, nuts, healthy fats, and wild-caught fish provide vitamins, minerals, antioxidants, fiber, and phytonutrients that support overall wellness.
My Philosophy on Nutrition and ITP
I was diagnosed with ITP in 2003 with a platelet count of just 2,000. After years of conventional treatments—including steroids, IVIG, Rituxan, and a splenectomy—I eventually entered remission in 2006. Since then, I've spent nearly two decades studying nutrition, inflammation, and lifestyle approaches that support whole-body health. I believe our daily choices influence the environment in which healing takes place. It's about nourishing your body consistently.
Rather than asking whether one food has a tiny effect on platelet function in a laboratory study, I encourage people to ask a bigger question:
Does this food help create an environment where my body can thrive?
Food isn't magic, and no single food will cure ITP. (Which is most likely why doctors make the statement that "food doesn't matter.) But our daily food choices absolutely influence inflammation, gut health, immune function, oxidative stress, blood sugar regulation, and overall health.
Those are all areas worth supporting.
Instead of demonizing nutritious whole foods, I encourage an evidence-informed approach that focuses on the overall dietary pattern rather than isolated ingredients.
Choose wisdom over fear.
What foods should people with ITP focus on?
A nutrient-dense diet emphasizing whole foods, fruits, vegetables, healthy fats, lean protein, and anti-inflammatory eating patterns may support overall wellness while reducing chronic inflammation.

If you're ready to go beyond Google searches and dive deeper into the science of nutrition, inflammation, autoimmune health, and natural wellness, I'd love to invite you to join the Faith & Wellness Collective.
Each month we explore practical, evidence-informed topics designed to help you care for your body, strengthen your faith, and build a healthier lifestyle. Members receive exclusive classes, a growing resource library, live Q&A sessions, healthy recipes, wellness education, and a supportive community committed to pursuing healing with hope—not fear.
If you've ever wished someone would explain the "why" behind nutrition instead of simply handing you another list of foods to avoid, the Faith & Wellness Collective was created for you.
I hope you'll join us as we continue learning, growing, and pursuing wellness together.
