Selenium is a powerful mineral that plays a crucial role in maintaining your overall health. Selenium rich foods should be one of your main goals to providing a healthy, balanced diet. From supporting a healthy immune system to promoting thyroid function (to boost your metabolism) and aiding in antioxidant defense, selenium is a nutrient you don’t want to miss out on. Originally, this post was to be the Top 10 Selenium Rich Foods. To help you make the most of this essential mineral, I’ve extended the search and scoured the web to compile a list of the Top 20 selenium rich foods that are wheat free, primarily low-carb and commonly available in a variety of countries (not all sources are widely available), complete with their respective selenium content. Including these delicious options in your diet can lead to a more vibrant and balanced life.
Individual nutritional values may vary. This depends on the geographic location and environmental conditions of the food source and cannot be 100% consistent. Scientific analysis / detection of nutrients in food sources may also have slight variances in the nutritional values.
Additionally, I have categorised the Sources of Selenium into the following groups :
- Nuts and Seeds
- Fish and Shellfish
- Meat
- Additional Sources
Selenium Rich Foods : Nuts and Seeds
1. Brazil Nuts
Brazil nuts are the reigning champions of selenium. Just 1 Brazil Nut provides your recommended daily intake of 55mcg selenium [1]. 100g of Brazil nuts provide 1920mcg Selenium / 100g. This equates to : 3491% Daily Value
“A small-scale 2014 study looked at the health effects of eating one Brazil nut per day in people with chronic kidney disease. After 3 months, the researchers noticed a reduction
in inflammation and markers of oxidative stress.” [1]
A study in the European Journal of Nutrition reported that eating one Brazil nut per day for 8 weeks lowered total cholesterol and fasting glucose levels in healthy adults.
The findings of another 8-week-long study showed that taking a 200-mcg selenium supplement reduced insulin levels and improved insulin sensitivity in people with type 2 diabetes and coronary heart disease. The researchers also reported increased antioxidant capacity in the body. Enjoy them as a snack or sprinkle them on salads for a delicious and nutritious boost.
2. Sunflower Seeds
Not just delicious, sunflower seeds are also rich in selenium. 1 oz Sunflower seeds provide 32% of the RDI [3]. 100g Sunflower seeds provide 80.4mcg Selenium (146% Daily Value)

Roast, grill, or include it a fried rice dish or chow-mein for a versatile and nourishing option.
Tip: When roasting any poultry, place in roasting tin resting on the breast fro 30 – 40 minutes. This allows the fats in the back to soften and run down through the meat into the breast with other juices. Rotate the bird onto its back after 45 minutes (30-40% total cooking time) and continue cooking until the juices run colourless form the thickest part of the joint / breast and the skin is brown and crispy. Cooking the bird this way creates a succulent moist breast full of flavour and prevents food poisoning from raw white meat.

Additional Selenium Rich Foods
While the above list represents 20 top sources of selenium, there are additional sources we must also consider. While these may have reduced selenium content, they can provide additional nutrients and so are included in this additional list of selenium rich foods.
Tofu
Tofu is a food prepared by coagulating soy milk and then pressing the resulting curds into solid white blocks of varying softness: silken, soft, firm, extra (or super) firm. Tofu is also known as bean curd in English [11].
When prepared with calcium sulfate, Tofu provides 17.4 mcg Selenium per 100g equating to 32% DV.
However, while rich in selenium and being vegetarian, Tofu is made with soy milk. Soy milk (as with many soy based products) is not good for weight loss.
Scramble, boil, or poach them for a delightful addition to your meals. Alternatively, try a delicious French styled cheese omelette. Delicious and with a gooey centre of molten cheese and soft, lightly cooked egg!!
Brown Rice (1 cup cooked – 19 mcg)
Whilst many of us are used to seeing and consuming the refined and polished white rice, brown rice is a whole grain. It contains more overall nutrition than its paler counterpart. Due to the varying processes through different manufacturers, the levels of nutrition in brown rice vary more than in other foods. White rice typically provides 14% of the DV Selenium vs 27.3% of the DV for selenium in 1cup of Brown Rice [10].
A nutritious whole grain, brown rice is a valuable source of selenium. Use it as a base for stir-fries, salads, or as a side dish to complement your meals.
However, caution needs to be taken as brown rice is also rich in complex carbohydrates. Carbohydrates in all forms contribute to weight gain unless strictly regulated.
“Nuts, seeds, and whole grains like brown rice also contain phytic acid, a substance that can bind to the minerals calcium, iron, and zinc. Some whole grains contain enough phytase, the enzyme required to break down phytic acid, while others like oats, brown rice, and legumes don’t” [9].
Research has also shown phytic acid to have health benefits like antioxidant activity, and cancer and kidney stone prevention, so it’s not necessarily something to completely avoid.
Selenium in Chia Seeds
Chia seeds are a noteworthy inclusion in a weight loss-centered diet, offering a versatile and nutrient-dense option that’s particularly rich in fiber and healthy fats. These tiny seeds provide a feeling of fullness and sustained energy, making them an excellent addition to support weight management.

Chia seeds, a healthful alternative to bread, are also a good source of selenium. These tiny powerhouses can be added to smoothies, yogurt, or used as a topping for oatmeal.
To incorporate chia seeds into your weight loss plan, try creating a nutritious chia pudding by soaking them in almond milk overnight and topping with fresh berries. This approach delivers a satisfying and nourishing choice that aligns well with your weight loss objectives.
Shiitake Mushrooms
Incorporating these selenium-rich foods into your daily intake can help you meet your selenium needs, fostering a strong immune system, healthy thyroid function, and overall well-being. Shiitake mushrooms are a popular mushroom variety that offers a good source of selenium providing 65% of the daily value per 145-gram cup serving.
Shiitake Mushrooms can incorporated into many dishes and provide 24.8 mcg (45% DV) per 100g serving for Selenium.
Remember to seek a diverse range of nutrient-dense foods to ensure a balanced diet that covers all essential vitamins and minerals.
Individual selenium requirements may vary based on factors such as age, gender, and activity level. Consult with a registered dietitian or healthcare professional to determine the ideal selenium intake for your specific needs.
