We all need nutrients to lead a healthy life. A balanced diet usually requires all the necessary food components like carbohydrates, proteins,
fats, vitamins and minerals. Maintaining a balanced diet with various
nutrient-rich foods helps you get the essential minerals your body needs
to function optimally.
Besides other food components minerals also play a crucial role in
various bodily functions, from bone health to immune support. Deficiencies or
imbalances in these minerals can lead to health issues, so it's
important to include sources of these nutrients in your daily diet.
Essential
Minerals needed by our body
A few essential minerals that you can easily get from your food and are important for your body are:
Calcium:
Calcium is found
in dairy products, leafy green vegetables, and fortified plant-based milks. A calcium deficiency can lead to weakened bones (osteoporosis),
muscle cramps, and problems with nerve and heart function. On the other hand,
excessive calcium intake can lead to kidney stones and impaired
absorption of other essential minerals. It's important to get an adequate amount
of calcium through diet or supplements
Iron:
Iron is present in red meat, beans, lentils,
and spinach. Iron balance in the body is carefully regulated, as both
deficiency and excess can lead to health problems. Iron deficiency can result
in anaemia, characterized by fatigue, weakness, and impaired cognitive function.
On the other hand, too much iron can lead to conditions like hemochromatosis,
which can damage organs such as the liver and heart.
Iron is obtained from dietary sources, with heme iron (found in animal
products like red meat) being more easily absorbed than non-heme iron (found in
plant-based foods like beans and spinach). Vitamin C can enhance the absorption
of non-heme iron, while substances like calcium and certain polyphenols can
inhibit it.
Magnesium:
Magnesium is available in nuts, seeds, whole
grains, and green leafy vegetables. Often magnesium deficiency can lead to
symptoms such as muscle cramps, fatigue, irritability, and irregular heartbeat.
Chronic deficiency can also contribute to more serious health issues like
osteoporosis, cardiovascular disease, and diabetes.
You can easily get sufficient magnesium from a balanced diet that
includes foods like nuts, seeds, whole grains, leafy green vegetables, and
legumes. In some cases, supplements may help you to recover from deficiencies
or meet specific health needs.
Potassium:
Potassium is
found in bananas, oranges, potatoes, avocados and spinach. Potassium deficiency
can lead to symptoms such as muscle cramps, weakness, fatigue, and irregular
heartbeats. Severe deficiencies can result in more serious health issues, such
as kidney dysfunction and abnormal heart rhythms.
On the other hand, excessive potassium levels can also be harmful and
potentially dangerous leading to irregular heart rhythms and other
complications.
You can fulfil potassium needs through a diet rich in fruits,
vegetables, legumes, and whole grains.
Zinc:
Zinc is found
in meat, shellfish, dairy products, and legumes. If you are deficient in zinc, it
can lead to a range of health issues, including impaired immune function,
delayed wound healing, growth retardation in children, loss of appetite, and
hair loss. On the other hand, excessive zinc intake can interfere with the
absorption of other essential minerals like copper and iron and can lead to
gastrointestinal issues and other health problems.
Zinc can be obtained from dietary sources such as meat, shellfish, dairy
products, nuts, seeds, and whole grains. Supplements may be
needed to address deficiencies or meet specific health needs.
Role of Minerals in Health
Minerals play
a crucial role in maintaining health by supporting various physiological
functions and processes. Here are some key functions and roles of minerals in
the body:
1. Bone
Health:
Minerals like calcium, phosphorus, and magnesium are essential for
the development and maintenance of strong bones and teeth. Calcium, in
particular, is crucial for bone density and strength. It is essential for the
development and maintenance of strong bones and teeth. Adequate calcium intake
helps prevent osteoporosis. Similarly, phosphorus works along with calcium to
build and maintain healthy bones and teeth.
2. Electrolyte
Balance:
Sodium, potassium, and chloride help maintain fluid balance,
regulate blood pressure, and support proper nerve and muscle function. They are
essential for maintaining the body's electrolyte balance and ensuring proper
cellular function.
3. Muscle
Function:
Minerals like calcium, potassium, and magnesium are involved in
muscle contraction and relaxation. For example, calcium is needed for muscle
contraction, while magnesium helps muscles relax and function. Potassium helps to
regulate muscle contractions and nerve signals. Low potassium levels can lead
to muscle cramps and weakness.
4. Nerve
Function:
Calcium, potassium, and sodium are essential for nerve impulse
transmission. They help generate and transmit electrical signals between nerve
cells, which is critical for proper brain and nervous system function. Sodium regulates
nerve function and fluid balance. It's crucial for transmitting nerve impulses.
While calcium facilitates nerve signal transmission and muscle contractions.
5. Blood
Health:
Iron is a key component of haemoglobin, the protein in red blood
cells that carries oxygen from the lungs to the rest of the body. Zinc and
copper are also important for maintaining healthy blood and supporting the
immune system.
6. Immune
System:
Zinc, selenium, and copper play roles in maintaining a healthy
immune system. They help regulate immune responses and protect cells from
oxidative damage. Zinc is vital for maintaining a healthy immune system and
wound healing. Selenium acts as an antioxidant and supports immune function.
7. Energy
Production:
Magnesium, iron, and other minerals are involved in the body's
energy production processes. For instance, magnesium is a cofactor in numerous
enzymatic reactions that help convert food into energy. Iodine is necessary for
the production of thyroid hormones, which regulate metabolism, energy
production, and overall growth.
8. Hormone
Production:
Certain minerals, like iodine, are essential for the production of
hormones. Iodine is crucial for the synthesis of thyroid hormones, which
regulate metabolism and growth. Calcium plays a role in hormone secretion and
regulation.
9.
Antioxidant Protection:
Selenium and zinc
have antioxidant properties, helping to protect cells from damage caused by
free radicals. This can reduce oxidative stress and lower the risk of chronic
diseases.
Mineral
Deficiency
A deficiency in essential minerals can lead to various health issues,
depending on which mineral is lacking. Here’s a look at some common mineral
