Nowadays, more and more people struggle with thyroid problems, and one of the most common autoimmune disorders is Hashimoto’s disease. Many studies indicate that a proper diet can significantly impact the health of patients. One of the most effective nutritional approaches appears to be a low-carb diet and avoiding brominated flour, which may negatively affect thyroid function.
How Does a Low-Carb Diet Affect Hashimoto’s?
A low-carb diet involves reducing carbohydrate intake, especially those with a high glycemic index, and replacing them with healthier fats and protein. In the context of Hashimoto’s, this can bring several benefits:
- Reducing Inflammation – Hashimoto’s is an autoimmune disease in which the immune system attacks the thyroid. Reducing simple sugars and processed foods helps lower inflammation and decreases the autoimmune response.
- Stabilizing Blood Sugar Levels – People with Hashimoto’s often suffer from insulin resistance. A low-carb diet improves insulin sensitivity, which may support thyroid function and metabolism.
- Supporting Gut Health and Microbiota – Leaky gut can be one of the factors exacerbating Hashimoto’s. A diet rich in healthy fats and low-carb vegetables can help rebuild gut microbiota.
- Better Conversion of Thyroid Hormones – Hypothyroidism is often associated with poor conversion of T4 to the active T3 form. A low-carb diet may improve this conversion, especially when rich in healthy fats such as omega-3s.
Brominated Flour and the Thyroid – Why Avoid It?
Bromine is a chemical element that belongs to the same group as iodine, fluorine, and chlorine (halogens). It can compete with iodine, which is essential for producing thyroid hormones. Consuming products containing bromine (e.g., brominated flour) can lead to iodine deficiency and weakened thyroid function.
Negative Effects of Brominated Flour:
- Blocking Iodine Absorption – The thyroid may replace iodine with bromine, leading to disruptions in hormone synthesis.
- Increased Risk of Hypothyroidism – Bromine can weaken thyroid activity, leading to chronic fatigue, weight gain, and hormonal imbalances.
- Neurotoxic Effects – Excess bromine in the body may cause brain fog, concentration problems, and memory impairment.
Pesticides in Flour – A Hidden Threat to the Thyroid
Flour, especially conventional wheat flour, may contain pesticide and herbicide residues used during crop cultivation. Some of these can negatively impact thyroid health:
- Glyphosate – Used as a herbicide, it may disrupt enzymes responsible for thyroid hormone synthesis and weaken gut microbiota, which is crucial for autoimmune thyroid diseases.
- Chlorinated Pesticides – These may act as endocrine disruptors, interfering with the hormonal system, including thyroid function.
- Heavy Metal Residues – Some pesticides may contain trace amounts of heavy metals such as cadmium, which can weaken thyroid function.
For this reason, it is worth choosing organic flour from pesticide-free crops to minimize exposure to these substances.
Is Brominated Flour Everywhere?
- In some countries, such as the USA, brominated flour is still allowed.
- In the European Union, Canada, and China, the use of potassium bromate in food products is banned.
- In the UK, the use of brominated flour is banned, following the Bread and Flour Regulations of 1998. Additionally, mandatory fortification of flour with folic acid is planned to improve public health. People with Hashimoto’s in the UK do not need to worry about brominated flour, but it is still advisable to choose the least processed products that support thyroid health.
What Are the Best Alternatives to Brominated Flour?
To protect thyroid health, it is best to replace processed flour with healthier options:
- Almond, coconut, or flaxseed flour – Ideal for a low-carb diet.
- Chestnut or buckwheat flour – Suitable for those who want a moderate carbohydrate intake.
- Sourdough bread – Fermentation reduces the amount of anti-nutritional substances.
- Organic flour – If you consume wheat flour, choose products from organic crops to avoid pesticides.
Conclusion
A low-carb diet can be an effective support for people with Hashimoto’s disease, helping reduce inflammation, stabilize blood sugar levels, and support gut function. At the same time, avoiding brominated flour and pesticide exposure can prevent iodine deficiency and thyroid dysfunction, positively impacting overall health.
In the UK, the consumption of brominated flour is not a concern, as it is banned. Nevertheless, it is worth paying attention to product composition and choosing those that are the least processed and rich in nutrients that support thyroid health.
People with Hashimoto’s should make conscious food choices and avoid those that may worsen their condition. A healthy diet is key to improving well-being and better body function.
