Can I have a healthy immune system without minerals supplement?

To build the immune system up, minerals supplements are necessary, since our bodies can’t produce minerals independently on their own.
Zinc and Selenium are two minerals that strengthen the immune system, and keeps our bodies from sickness or disease.

Minerals supplement: Zinc Zinc is an essential mineral that is found in almost every cell.
It stimulates the activity of approximately 100 enzymes, which are substances that promote biochemical reactions in your body.

This valuable mineral increases the production of white blood cells that fight infection and helps them fight more aggressively. It also increases killer cells that fight against cancer and helps white cells release more antibodies. Zinc minerals supplement have been shown to slow the growth of cancer.

Zinc also increases the number of infection-fighting T-cells, especially in elderly people who are often deficient in zinc, and whose immune system often weakens with age. When zinc supplements are given to individuals with low zinc levels, the numbers of T-cell lymphocytes circulating in the blood increase and the ability of lymphocytes to fight infection improves.

Zinc is found in a wide variety of foods. Oysters contain more zinc per serving than any other food, but red meat and poultry provide the majority of zinc in the American diet. Other good food sources include beans, nuts, certain seafood, whole grains, fortified breakfast cereals, and dairy products.

A word of caution: too much zinc in the form of supplements (more than 75 milligrams a day) can inhibit immune function. It's safest to stick to getting zinc from your diet and aim for 15 to 25 milligrams a day.

Minerals supplement: Selenium
This mineral increases natural killer cells and mobilizes cancer-fighting cells. As an anti-oxidant, selenium can help protect the body from damaging effects of free radicals. Selenium may also prevent or slow tumor growth. Certain breakdown products of selenium are believed to prevent tumor growth by enhancing immune cell activity and suppressing development of blood vessels to the tumor. Antioxidant nutrients such as selenium help protect cells from oxidative stress, thus potentially slowing progression of diseases.

Best food sources of selenium are tuna, red snapper, lobster, shrimp, whole grains, vegetables (depending on the selenium content of the soil they're grown in), brown rice, egg yolks, cottage cheese, chicken (white meat), sunflower seeds, garlic, Brazil nuts, and lamb chops.

Severe zinc and selenium deficiency depresses immune function and may lead to sickness or disease.Minerals supplements like zinc and selenium supports a healthy immune system and is needed to fight infections and wound healing.
