Final answer:
The statement is false; essential trace minerals, while needed in small quantities, can cause health problems when consumed excessively. Consuming too much of a trace mineral can result in toxicity and related health issues.
Step-by-step explanation:
The statement, "Even though trace minerals are needed in very small quantities, they cannot cause health problems," is false. Trace minerals are indeed required in very small quantities for various bodily functions, but consuming them in excessive amounts can lead to health problems. For example, exposure to too much chromium can cause skin irritation, and high levels of arsenic, although essential at very low levels, can be toxic at concentrations around 7,000 parts per billion or higher. The key point is that the dose makes the poison, and this applies to all nutrients and minerals.
It is important that a balanced diet is maintained to get the necessary minerals which are included in whole grains, seafood, fruits, vegetables, nuts, and legumes. Overuse of dietary supplements or overconsumption of processed foods can add potentially toxic levels of minerals to the body. Therefore, while a properly balanced diet should naturally contain all the requisite trace minerals, taking additional supplements without due care can lead to health issues related to mineral toxicity.
