Overview of Selenium Intake and Why It is Useful:
Selenium is a trace mineral which is present in different foods which are very essential in the functioning of the body. It is also the major component which helps in:
- The process of excretion of free radicals causing cell damage: The process removes harmful cells due to free radicals.
- Selenium in Thyroid hormone regulation:It controls the production of hormones that are most important in metabolism.
- Immune system enhancement: These factors help the body to fight diseases and infections.
Although the human body uses Selenium in very little amounts, its lack of sufficient saturation may result in the body suffering from health challenges such as low immunity and hypothyroidism. But too much of it may result in toxicity. It is important defining ideal selenium levels to be achieved through diet.
Understanding the Daily Allowance of Selenium:
One of the things that ought to be considered is understanding the daily recommended intake of selenium as this helps in preventing one from suffering health related complications. The current recommendations are as follows:
- Infants (0-6 months): 15 micrograms (mcg) per day.
- Infants (7-12 months): 20 mcg per day.
- Children (1-3 years): 20 mcg per day.
- Children (4-8 years): 30 mcg per day.
- Children (9-13 years): 40 mcg per day.
- Teenagers (14-18 years): 55 mcg per day.
- Adults (19 years and older): 55 mcg per day.
- Pregnant women: 60 mcg per day.
- Women feeding with breast milk: 70 mcg per day.
Nevertheless, most of these numbers depend so much on average requirements and because of that they will differ from individual health status. In this case, seeking alternative recommendations with the aid of a specialist is a very good idea.
Finding Foods Rich in Selenium:
Following a diet consisting the selenium containing foods is critical in ensuring the health of a person. These foods cover a wide collection among others both animal and plant.
Animal Based Sources:

- Meat: Beef, lamb, pork, and poultry are good sources and provide varying amounts of selenium in each of the meats.
- Organ meats: Selenium levels are very high in kidney, liver, and heart.
- Dairy products: Milk and cheese and protein foods of eggs supply selenium, but in rather smaller amounts.
- Shellfish: Include shrimp, oysters, clams… They contain selenium and meet the dietary needs.
Plant-Based Sources of Selenium:
These dietary sources of selenium are important for people who practice vegetarian and vegan diets.
- Brazil Nuts: They are one of the highest selenium source from plant origin. Just two nuts may be able to fulfil or exceed the daily required selenium level.
- Sunflower Seeds: A fair choice. They contain a reasonable dose of selenium interestingly with other nutrients.
- Brown Rice: This is another type of food that contains selenium and it is a common food in most countries.
- Beans and Lentils: Provide selenium of plant origin but to a varying degree by type.
- Spinach and Broccoli: Especially leafy vegetables with selenium. A supplement is essential for a healthy diet.
The Role of Soil Quality in Plant Selenium Content:
Of all the factors that determine the amount of selenium in plants, soil quality seems to matter most. The following factors control the amount of selenium available in the soil:
- Soil pH: It is known that severely acidic or alkaline soils will increase selenium excretion from the plants.
- Organic Matter: A high level of organic matter will promote the uptake of selenium.
- Soil Type: Sandy soils tend to have a lower selenium content than clay soils.
- Moisture: Appropriate soil moisture conditions can improve the movement and uptake of selenium by plants.
- Microbial Activity: Soil microorganisms are instrumental in bioconverting selenium into a form that plants may absorb.
To have desirable levels of selenium in their crops, farmers as well as gardeners have such variables to…
Selenium Content in Nuts and Seeds:
Nuts and seeds are remarkable in that they contain selenium and as such go a long way in meeting daily requirements.
- Brazil Nuts: These are among the nuts which contain high seleno, it is average to provide 96 micrograms of selenium per nut, which is higher than the daily dose reference.
- Sunflower Seeds: It should come as no surprise to anyone that such seeds are also a very healthy option as the amount of selenium available in them is roughly 79 micrograms per serving (100 grams).
- Chia Seeds: Each 100 grams serving of these seeds provides close to 55 micrograms of selenium, fortifying diet with virtues of selenium.
- Sesame Seeds: These seeds add about 34 micrograms of serving (100 grams) selenium, increasing the concentration of the mineral.
- Flaxseeds: These quantities contribute approximately 25 micrograms of selenium per head per 100 keratomes making for healthy eating.
Incorporating Fish And Seafood Rich in Selenium into the Diet:
To achieve the optimal selenium level, selenium-rich foods such as fish and seafood should be added to the diet. These foods provide plenty of selenium as well as other vital nutrients. Some of the important options include:
- Salmon: Contains a lot of selenium, good for the heart.
- Sardines: Replete with selenium, omega-3s.
- Tuna: Quite a healthy option, it is useful for the brain.
- Halibut: Contains a lot of selenium; helps to build bones.
- Shrimp: Contains a reasonable proportion of selenium as well as protein.
Including these foods regularly helps to increase the intake of selenium in the body without forgetting the requirements of fatty acids and the vitamins for health.
Optimising the Selenium Rich Content of Fruits and Vegetables:
It is important to appreciate how to make use of the high selenium content of some violaceous fruits and vegetables. Although these edible crops may not be high in selenium, several factors may increase their selenium content.
- Soil Quality: Fruits and vegetables that are grown in selenium-enriched soil have more selenium.
- Organic Fertilizers: Making use of organic fertilizers helps in biofortifying vegetables.
- Crop Rotation: Increasing soil selenium by planting crops that accumulate selenium.
- Food Preparation: How food is cooked has an effect on how much selenium will be retained. Steaming and stir-frying is better than boiling.

In the most extreme cases, selenium deficiency can result in even more serious conditions:
- Keshan Disease: Potentially fatal type of cardiomyopathy (rare).
- Kashin-Beck Disease: A disease of chronic degeneration of bones and joints.
Balancing Selenium Intake and Avoiding Toxicity:
To ensure proper selenium intake, titration must be enforced.
Recommended Dietary Allowance (RDA):
- Adults: 55 micrograms/day.
- Pregnant women: 60 micrograms/day.
- Lactating women: 70 micrograms/day.
Excessive intake of selenium may lead to its toxicity and clinical challenges include headaches, nausea and vomiting.
Symptoms of Toxicity:
- Nausea
- Hair loss
- Fatigue
- Irritability
Toxicity can be prevented by having selenium-rich alternatives and these include:
