[12:14.90]Minerals
[12:16.58]Minerals are non-organic substances
[12:19.48]which contain the element carbon.
[12:22.47]But they are vital for good health
[12:24.60]and have many key roles to play in the body.
[12:29.53]Minerals needed daily are present
[12:31.31]in almost all cells of the body.
[12:34.46]They can ensure our internal systems function efficiently.
[12:39.25]Without minerals,
[12:40.53]the body would not be able to build new tissues,
[12:43.37]regulate body processes or release energy from food.

[12:48.92]Acute imbalances of the daily needed minerals
[12:52.59]can be potentially fatal.
[12:54.73]On one hand,
[12:56.40]mineral shortages may lead to health problems
[12:59.70]such as failure to thrive in babies
[13:02.30]and an increased risk of heart disease.
[13:05.40]On the other hand,
[13:06.62]taking in too many dietary minerals
[13:09.41]can also harm the body.
[13:11.71]For example, too much calcium in the blood
[13:14.96]may cause vomiting, loss of appetite
[13:17.65]and irregular heart rate.

[13:20.45]Thus mineral shortages or taking excessive minerals
[13:24.05]should be carefully avoided
[13:26.08]through a balanced diet in our daily life.
