Selenium Consumption: The Importance for Human Health

Best Known Functions of Selenium Consumption: Where and Why Would Selenium Be of Use?

Selenium is one of the various trace minerals that are critical and necessary for human beings.

• Antioxidant Properties: Mostly this mineral is known for its antioxidant properties in that, selenium is incorporated with other vitamins to strengthen the antioxidant defense of the body against harmful free radicals.
• Thyroid Health: This is essential for the normal smooth operation of the triangular thyroid gland, as well the making of the hormonal production of the thyroid gland.

The Possible Benefits from the Selenium Supplement:

Selenium is an essential trace element that has a great impact on human health. Selenium has a function similar to that of vitamin E, by which it protects the cells from stress by acting as an antioxidant. Other important functions of selenium include:

• Immune System Support: Selenium augments immune response and safeguards against various infectious diseases.
• Thyroid Function: That is responsible for the production of thyroid hormones that help control the body’s metabolism.
• Antioxidant Properties: The enzymatic activity of selenium on some biologically active compounds is anti-oxidative, thus preventing cellular oxidation injury.

• Cognitive Decline: Increased chances of cognitive dysfunction which predisposes to neurodegenerative disorders.
• Reproductive Health: Can prove to be a challenge for many women who aspire for conception and reproductive health.
• Oxidative Stress: August, 2004 Lack of selenium may increase oxidative stress as well as inflammation in the body.

Benefits of Foods Rich With Selenium Consumption:

Selenium is classified as one of the essential trace elements and is important in many processes within the body. Satisfaction of the required Selenium levels in the diet leads to such advantages like:

• Antioxidants: Activity of selenium helps to eradicate free radicals and prevents further oxidative damages to cells.
• Thyroid Function: The appropriate production and functioning of this hormone are critical in metabolic activities of the body.
• Immune System Support Benefits: Selenium has been established to increase immunity and hence the body’s ability to combat infections.
• Heart Health: It can minimize inflammation and reduce the chances of developing heart related illnesses.
• Cognitive Function: The intake of selenium in model organisms has been linked to reduction in cognitive decline and enhancement of brain.

However, potential risks and toxicity of selenium over intake:

On the other hand, taking too much of selenium may lead to other health risks and toxicities. An overdose of selenium is liable to induce a variety of symptoms and conditions such symptoms and some other marketed conditions include:

• Gastrointestinal Notes: Nausea, vomiting and diarrhea.
• Neurological Notes: Dizziness, nervous and nervous shaking.
• Dermatological Notes: Thinning hair, pliant nails and rashes on the skin.
• Breath Odor: Auritus, resembling that of garlic, is also a feature of selenium poisoning.
• Severe Toxicity: High level toxicity may lead to breathing problems, renal failure, heart disease, and in some cases death.

Thus, sequential adjustment of selenium intake while diagnosing reasons of selenium toxicity can eliminate any health risks to arise from excessive.

Outcomes of Selenium Supplementation: When, How and why?

The term selenium supplementation may be uttered under certain conditions:

• Low Selenium Levels: Which can be established by the means of blood tests normally done by health care provider.
• Dietary Restrictions: People who strictly adhere to vegan or vegetarian lifestyles may be in position to need supplementation.
• Health Conditions: Suffering from Hashimoto’s or the Grave’s disease may require some additional preparations with selenium.
• Environmental Factors: Areas with lower selenium provision in the soil may require supplementation.

Administration Guidelines:

• Dosage: In adults, 55mg is the more common recommended dosage to take every day. More accurate than those have been provided from healthcare personnel.
• Form: Some of these forms of selenium include selenomethionine, sodium selenite, and Methionine.
• Timing: Taken with/just after meals in most cases to facilitate absorption into the body.
• Potential Interactions: Note, however, the latter should not be excessive especially when combined with other medicines e.g. anticoagulants.

Equal Proportion of Selenium Consumption: What is Proper Level of Selenium Intake for Each Person?

And finally, it helps to attain an optimal health where the level of selenium is well regulated.

• Include more types of foods: Such include selenium food sources such as Brazil nuts, seafood, chicken,-grains and other more.
• Avoid Large Quantity: Be aware of portion sizes, and especially on those particular foods high in selenium such as Brazil nuts.
• Keep Track of the Daily Values: Use labels to be certain that the recommended daily values are met.
• Selenium with Other Nutrients: Take selenium while eating vitamins E and C for better retention.
• Use Dietary Supplement Prudently: Never use a dietary supplement of selenium unless dietary intake is less, and seek medical consultation.

Selenium Consumption in Plant-Based vs. Animal Sources:

Sustainability of nutrition including selenium in both plant-based foods and animal-based foods is in differences of their concentration in soil and ability of the body to utilize it.

Plant-Based Sources:

• Whole grains: Brown rice, oats, and barley are also whole grains.

• Nuts and seeds: Brazil nuts are more relevant than sunflower or chia seeds
• Vegetables: Cooked spinach is especially useful, as well as broccoli garlic and mushrooms.

Animal-Based Sources:

• Seafood: Tuna sardines and are shrimp cereals.
• Meat: Beef, chicken, turkey, and pork are familiar to all especially children.
• Dairy products: Cheese yogurt and milk could be called fonem.
• Eggs: Yolk is the main one in this group and among dietary sources.

Compared to plant-based sources, uptake of selenium from animal foods may be more efficient.

Cooking and Storing Ways to Maintain Integrated Selenium in Foods:

• Reduce Cooking Times: In cooking foods rich in selenium, proper cooking time should be maintained so as not to battle the selenium level in the food. Steaming or microwaving is preferable to boiling.
• Minimize Water Use: In boiling, you should use only a minimal quantity of water as selenium can be lost in the water. Reuse broth or other liquid in cooking to avoid discarding nutrients.
• Store Properly: For nuts and seeds or selenium rich foods, pack them in a container with air tight seal to reduce oxidation and loss of selenium.
• Store at LowTemperature: Store some of these foods to cool and dark places. Some sources of selenium can be lost by prolonged exposure to heat and light.
• Eat Fresh: It is important to eat fresh fruit and vegetables as soon as they are obtained.

Common Myths About The Use Of Selenium:

There are many myths regarding health and the consumption of selenium:

• Thyroid is the only target organ for selenium: It is needed for normal functioning of the thyroid gland and more importantly, immunity and oxidative stress.
• Selenium has toxicity as its only characteristic: Only toxic in higher than recommended amounts, otherwise S.A.D T.D is helpful.
• All sources of selenium are similar: Organic ones e.g. selenomethionine, selenocysteine have greater bio-availability than inorganic.
• Selenium has to be supplemented always: Most times, adequate selenium intake can be obtained with proper diet.
• Selenium can fertilize illnesses: It is helpful but does not treat; to treat the condition or disease, one needs to exercise appropriate medical care.
• No selenium can be reached by vegetarians or vegans: There are such sources but they are more subdued.
