The Importance of Selenium for Diabetics

Selenium is a powerful mineral that plays an essential role in supporting the healthy functioning of your body. It helps neutralize excess free radicals and protects cells from damage caused by oxidative stress, which can contribute to various chronic diseases. Selenium-rich foods are especially beneficial for diabetics as they can bolster immune health and enhance thyroid functioning.


Neutralizing Excess Free Radicals

Free radicals are unstable molecules that can cause damage to our cells when their levels become too high. This process is known as oxidative stress, and it has been linked to numerous health issues such as inflammation, heart disease, cancer, and diabetes complications. Selenium can help combat oxidative stress by neutralizing free radicals, thus protecting our cells from damage and supporting the immune system.


Protecting Cells from Oxidative Stress

Oxidative stress not only damages cells but also weakens the immune system – something diabetics should be wary of since they often have compromised immunity due to their condition. By incorporating selenium-rich foods into your diet, you’ll provide your body with this essential mineral needed for optimal cellular protection against oxidative stress-related damage while simultaneously boosting overall immune health.


  • Selenium content: Ensure you consume enough selenium through dietary sources like Brazil nuts or fish.
  • Dietary sources: Choose whole foods over processed ones whenever possible for better nutrient absorption.
  • Selenium’s role: Remember its crucial role in maintaining proper thyroid function and immune health, especially for diabetics.
  • Essential mineral: Don’t overlook the importance of selenium in your daily diet – it’s vital for optimal well-being.

Now that you understand the significance of selenium in a diabetic’s life, let’s dive deeper into how this mighty mineral supports thyroid health and diabetes management.

Key Lesson: Selenium is a mineral with powerful antioxidant properties that can help diabetics protect their cells from oxidative stress and boost immune health. Diabetics should consume foods high in selenium to support healthy thyroid function and optimize their overall health.

Thyroid Health and Diabetes Management

Maintaining thyroid health is essential for overall wellness, especially in those with diabetes. As the maestro of hormones and metabolism regulation, this little butterfly-shaped organ is crucial for overall well-being. For individuals with diabetes, keeping the thyroid in tip-top shape is especially vital since hormone imbalances can exacerbate diabetic symptoms.


Selenium enters the scene as our trusty sidekick by aiding in optimal thyroid function and preventing conditions like Hashimoto’s disease, an autoimmune disorder affecting the gland. Let’s dive into how selenium supports thyroid health and helps manage diabetes more effectively:


Hormone Regulation Through Proper Thyroid Function

  • T4 Conversion: Selenium plays a key role in converting thyroxine (T4) to its active form triiodothyronine (T3), which is essential for regulating metabolism.
  • Antioxidant Protection: The essential mineral also acts as an antioxidant that protects your thyroid from damage caused by free radicals – those pesky molecules responsible for cellular deterioration.
  • Blood Sugar Balance: A well-functioning thyroid ensures proper insulin production and utilization, helping maintain stable blood sugar levels – something every diabetic strives for.

Preventing Hashimoto’s Disease With Selenium Intake

The relationship between selenium content and Hashimoto’s disease has been extensively studied. Research suggests that adequate dietary sources of selenium may help reduce inflammation within the gland itself while promoting normal immune response against potential threats – all leading to a healthier thyroid.


One study found that selenium supplementation significantly reduced thyroid antibodies in patients with Hashimoto’s disease, suggesting the mineral may play a therapeutic role in managing this autoimmune condition. For diabetics, keeping Hashimoto’s at bay means better hormone regulation and improved blood sugar control.


Adding selenium-containing foods to your diet may help regulate hormones and support better blood sugar control in those with diabetes and Hashimoto’s disease. So go ahead – give your body the essential minerals it needs to thrive.


Selenium is a key element for preserving thyroid and diabetic balance, as it facilitates the regulation of hormones in the organism. Additionally, selenium can provide a variety of other benefits such as reducing cancer risks and inflammation related to heart health.

Key Lesson: Selenium is a vital mineral for optimal thyroid health and diabetes management, as it helps convert T4 to its active form of T3, provides antioxidant protection from free radicals and maintains insulin production. Adding selenium-packed edibles to your eating regimen can be a viable approach to furnish the body with what it needs for enhanced hormone balance and better blood sugar management.

Additional Health Benefits of Selenium

Selenium is not only beneficial for immune system and diabetes control, but also offers a range of other health advantages that make it an indispensable mineral. Let’s dive into some of these impressive perks:


Lowering Cancer Risks

Selenium plays a crucial role in reducing the risk of certain cancers, including lung, prostate, and colorectal cancer. This mighty mineral aids in DNA repair and prevents the formation of harmful free radicals within cells. Selenium’s apoptotic effects selectively target cancerous cells, leaving healthy ones unscathed.


Reducing Inflammation Related to Heart Health

Your heart will thank you for incorporating more selenium-rich foods into your diet. Research has shown that higher dietary intake or supplementation with this essential mineral can help reduce inflammation markers associated with cardiovascular disease. As we know, chronic inflammation is one major factor contributing to heart problems; thus, consuming adequate amounts of selenium may contribute significantly towards maintaining a healthy ticker.


Asthma Relief & Slowing Age-Related Mental Decline

  • Asthma relief: Studies have found that individuals with asthma tend to have lower levels of selenium than those without the condition. Increasing your daily intake could potentially help reduce asthma-related symptoms by boosting antioxidant activity within the body.
  • Mental decline prevention: Alzheimer’s disease is often linked to oxidative stress and inflammation – two factors where our friend selenium comes into play. Consuming enough dietary sources of selenium may help slow age-related mental decline and protect against neurodegenerative diseases like Alzheimer’s.

As you can see, the benefits of incorporating more selenium into your diet go far beyond just supporting immune health for diabetics. This essential mineral is a true powerhouse that should be included in everyone’s daily nutritional intake to promote overall well-being.


Selenium, a potent nutrient, can bring about numerous health benefits when ingested as part of one’s diet. Ensuring adequate daily intake of selenium through food sources is an important step towards improving overall immune health for diabetics.

Key Lesson: Selenium is a powerhouse of health benefits, from reducing cancer risks to slowing age-related mental decline. Diabetics can enhance their immunity by including selenium-rich fare in their daily meals to promote wellness.

How much selenium do I need?

The amount of selenium that you need each day depends on your age. Average daily recommended amounts are listed below in micrograms (mcg).


Life StageRecommended Amount
Birth to 6 months15 mcg
Infants 7–12 months20 mcg
Children 1–3 years20 mcg
Children 4–8 years30 mcg
Children 9–13 years40 mcg
Teens 14–18 years55 mcg
Adults 19–50 years55 mcg
Adults 51–70 years55 mcg
Adults 71 years and older55 mcg
Pregnant teens and women60 mcg
Breastfeeding teens and women70 mcg


Now it’s just a matter of finding the right food to get your selenium from. You don’t need a lot at all – around 50-60 micrograms per day is fine. As long as you stay under around 300 micrograms you’ll be fine, but you shouldn’t go over that amount. Long-term intake of too much selenium can have harmful effects, including hair and nail loss, gastrointestinal symptoms, and nervous system abnormalities.

Ensuring Adequate Daily Intake Through Diet

If you’re looking to boost your selenium intake without going overboard or risking deficiency, the key is incorporating a variety of dietary sources into your meals. Not only will this ensure that you’re getting enough of this essential mineral, but it’ll also make for some tasty and nutritious dishes.


Brazil Nuts as a Top Source of Selenium

Brazil nuts are hands down one of the best sources of selenium out there. Just one nut can provide more than 100% of your daily recommended value. So go ahead and snack on these delicious treats – just remember that moderation is key since too much selenium can have adverse effects.


Incorporating Fish, Meat, Eggs, and Whole Grains into Your Diet

  • Fish: Tuna and sardines are excellent options when it comes to upping your selenium content. Try adding them to salads or enjoying them in sandwiches for an easy meal packed with nutrients.
  • Meat: Organ meats like liver boast high levels of selenium. Why not experiment with organ meats and add a nutritious twist to your cooking repertoire?
  • Eggs: An eggcellent (pun intended) source of protein and other vital nutrients like vitamin D and choline; eggs also contain decent amounts of selenium. Whip up an omelet or scramble some eggs for breakfast – yum.
  • Whole grains: Foods such as brown rice, quinoa, barley, and whole wheat bread are not only high in fiber but also contain a good amount of selenium. Incorporate these grains into your meals for an extra nutritional boost.

Of course, if you’re struggling to get enough selenium through diet alone, it’s worth considering multivitamins or dietary supplements. However, always consult with your healthcare provider before starting any supplementation program to ensure it’s safe and appropriate for your individual needs.

Key Lesson: Selenium is an essential mineral that can be easily incorporated into your diet through brazil nuts, fish, meat, eggs and whole grains. Consult your doctor before taking selenium supplements, as excessive intake may cause harm. Make sure you’re getting the most bang for your buck by eating a variety of selenium-rich foods.

Functional Medicine Approaches to Selenium Deficiency

As a busy professional, you may be wondering how to ensure your selenium intake is on point. That’s where functional medicine comes in. This holistic approach addresses selenium deficiency by focusing on personalized nutrition plans that incorporate appropriate amounts of this vital mineral. By doing so, it helps improve thyroid health in diabetics while also supporting their immune system defenses against various infections or chronic diseases associated with compromised immunity status.


Personalized Nutrition Plans for Diabetics

A key aspect of functional medicine is its emphasis on individuality. No two people are the same, and neither should their diets be. A personalized nutrition plan takes into account factors such as lifestyle habits, medical history, genetic predispositions, and environmental exposures – all of which can impact overall nutrient requirements differently from person-to-person depending on unique circumstances involved.


  • Lifestyle habits: Your daily routine plays a significant role in determining your nutritional needs. For example, someone who exercises regularly may require more protein than someone who leads a sedentary lifestyle.
  • Medical history: If you have diabetes or other health conditions that affect nutrient absorption or metabolism (such as celiac disease), your dietary requirements will differ from those without these issues.
  • Genetic predispositions: Your genes play an essential part in determining how well your body absorbs certain nutrients like selenium; thus making sure you consume enough becomes even more critical if there’s any family history related to deficiencies within this area.
  • Environmental exposures: Pollution levels surrounding living areas could potentially influence nutrient absorption rates due to various factors involved within such situations; hence why it’s crucial to consider these aspects when creating personalized plans tailored specifically towards each individual case scenario.

Addressing Deficiencies Through Targeted Supplementation

Despite eating a healthy diet, individuals may still not get enough selenium, necessitating targeted supplementation under medical supervision. In cases like these, targeted supplementation under medical supervision can help bridge the gap and ensure optimal health. A study published in Nutrients found that selenium supplements effectively increased blood levels of this essential mineral in individuals with low baseline concentrations.


Incorporating a well-rounded diet rich in selenium content is an excellent first step for diabetics looking to improve their immune health and thyroid function. However, if deficiencies persist despite conscious dietary choices or other confounding factors are present, functional medicine offers personalized solutions through targeted supplementation programs – ensuring you maintain optimal well-being while minimizing reliance on medications.

Key Lesson: With functional medicine, diabetics can improve their immune health and thyroid function by consuming selenium-rich foods or taking targeted supplements. This approach is an effective way to bridge any nutritional gaps without having to rely heavily on medications.

I wanted to talk about this topic because it is absolutely possible to prevent and even reverse Type 2 Diabetes (but you cannot reverse Type 1).  Yes, it’s possible! and emerging studies looking at lifestyle medicine and prevention support this! But I always tell my patients that you must be dedicated and diligent in adopting a healthy lifestyle to get the best results. You can create certain behaviors and practices that will not only enrich your life, but that you can pass on to your family, friends, and community, to help break the cycle of this chronic disease so that you can leave a legacy of health to your loved ones.


I use functional medicine and lifestyle medicine as the first line of treatment, before medications, to treat lifestyle-related chronic diseases. Lifestyle-related chronic diseases include diabetes, hypertension, obesity, and some cancers, just to name a few. Lifestyle practices, such as eating a low glycemic, whole-food plant-based diet and regular physical activity, can help you improve your blood sugar levels, maybe reverse type 2 diabetes. In certain cases, these approaches may even outperform pharmaceutical therapy.


But I always tell my patients that conventional medications may be appropriate at this time to prevent catastrophic illness, but over time, you can work to make the necessary lifestyle changes to possibly reduce and/or eliminate medications. Please remember to always consult your physician for your particular needs and circumstances prior to making any decisions whatsoever.


Is Dietary Supplementation Right For You?

When it comes to managing your blood sugars (in general), pre-diabetes, and diabetes, there are many things that you can do to help control your blood sugar levels. One important aspect is diet. What you eat affects your blood sugar, so it’s important to be mindful of what goes into your body.


But it is very important to note that we are not eating the same foods we ate years ago because the soils have been depleted of critical nutrients through current industrial farming practices. And because the soil is not as good as it used to be, the food supply (grown from the depleted soil) is not as good as it used to be. For example, you are not getting the same levels of chromium and magnesium as you would have gotten 30 or even 50 years ago.


Second, much of the food has been processed and genetically altered, which can impact the inherent and unique nutritional composition that each food possess. For example, ancient einkorn wheat has less gluten, more protein, more Vitamin A, and more beta carotene, than modern genetically modified wheat.


Third, the toxic load in the environment today is much higher than 100 years ago. We can see this with global warming, toxic landfills, polluted oceans and waterways, etc. Toxicity levels interfere with nutrient assimilation and absorption not just into the foods, but into our bodies as well. We often see elevated blood sugar levels with poor nutrition and toxicity.


In addition to diet, there are dietary supplements that can have an impact on blood sugar levels. Dietary supplements for diabetes are becoming increasingly popular as people look for ways to improve their blood sugar control.


For some people, vitamin and mineral supplements offer important health benefits. Supplements are designed to fight deficiencies found in our diet and complement the food we eat regularly. Supplements are basically “helping hands” to our daily food.


If you suspect that you aren’t getting the nutrients you need, consider shifting your focus from supplements to eating better.


And if you are unable to eat better, the supplements in my Blood Sugar Support Bundle may provide the extra boost you need.

Blood Sugar Support Bundle


These are my favorite Diabetes Prevention Supplements to use! This Blood Sugar Support Bundle will ensure you have the intake of the important vitamins, minerals, and probiotics to decrease inflammation and boost your innate wellness day and night. Taken together, it’s a solid plan for increasing your body’s natural resiliency while encouraging healthy blood sugar levels.


For best results make sure you use these supplements with dietary changes including a whole food plant-based diet, regular exercise (at least 2-3x per week), regular sleep (8 hours per night), and intermittent fasting (at least 1-3x per week).


It’s important to note that supplements are NOT a replacement for your regular medication regimen prescribed by your doctor. However, they can be used in addition to help manage your blood sugar levels.


Supplements have the potential to interact with diabetes medications, so it’s important to speak with a healthcare provider before starting any new supplement regimen.  Have you tried any dietary supplements for your diabetes? Share your experience in the comments below!


Tools For Diabetes Prevention and Monitoring

Blood Sugar Monitoring

As you know, I always stress the importance of taking control of your health. Monitoring your blood sugar levels is one of the best ways to do this. To do this, a single drop of blood is collected with disposable lancets and placed on a disposable test strip, which you insert into a home blood-sugar monitoring device, called a glucometer.


The common times for checking your blood sugar are when you first wake up (fasting), before a meal, 2 hours after a meal, and at bedtime; however, you should check your blood sugar as many times a day as your health care team suggests.


Monitoring your blood sugar level provides you and your doctors with important knowledge about how food, activity, medication, stress, and other elements might affect your blood sugar levels. This data will assist you and your doctor in developing a therapy plan that is suited to your demands.


There are several types of blood glucose meters, lancets, and test strips to choose from. I often recommend this glucometer, lancets, and test strips.


Weight Monitoring

Since weight management is very important in combatting chronic diseases such as diabetes, I recommend that you be mindful of your weight and its fluctuations, and that you monitor your weight AT LEAST on a weekly basis. I recommend a scale that includes a body composition monitor (*this scale cannot be used with a pacemaker or other implanted devices).


Physical Activity

Physical activity (or exercise) can improve your health and reduce the risk of developing several chronic diseases like high blood pressure, type 2 diabetes, and cancer, just to name a few. Physical activity actually improves insulin sensitivity. Physical activity can improve your mood, boost your immune system, and even help you maintain a healthy weight.


I often recommend yoga and resistance training for physical activity, but as you are aware, there are plenty of forms of “movement” that you can do! But for the basics, especially if you’re just getting started, yoga and resistance training are where I would start.



Yoga can be a great way to improve your strength and flexibility, manage your stress, improve your heart health, and lose weight! I recommend using this yoga mat to get started with your yoga practice today!


Resistance Training

Resistance training is the mainstay for overall health. It not only has beneficial effects on reducing body fat, it also increases muscle size and strength. Here are some basic resistance bands that I recommend to everyone. They are great for physical therapy, yoga, strength training, and excellent for traveling.
