Every person's immune system defends it against disease-causing microorganisms. This is everybody's first line of defense against any sickness or infection.

According to a Harvard study, every part of the human body, including the immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies. This is achieved by exercising regularly, getting adequate sleep, minimizing stress, and eating a balanced and nutritious meal.

But a lesser-known fact is how iron is important in building immunity.

To further boost one's immunity, one can start the day by taking iron in every bowl of oatmeal. Oats are a natural source of iron and it helps the body generate white blood cells to fight against infection. In a way, immune cells serve as the body's 'frontliners' against bacteria and viruses. Furthermore, oats contain other vitamins and minerals necessary to maintain good health.

An iron deficiency can make the body more prone to diseases. With a bowl of oatmeal such as Quaker Oats for breakfast, you are starting your day with iron. It is the first meal of the day, so it is the perfect opportunity to gear up for the day's activities.

Take it from the Villaroel-Legaspi family, who boosts their immune system with an active lifestyle and a bowl of nutritious oatmeal daily.

''We try our best to eat healthy, to eat right,'' said Carmina Villaroel-Legaspi. ''And then, of course, we exercise a lot, we drink lots of water, and then take vitamins.''

''I am a true oatmeal lover,'' daughter Cassy Legaspi said. ''I eat it whether it is breakfast, lunch, merienda… actually even dinner.''

''And boosting your immunity is so important nowadays, especially with the health crisis,'' son Mavy Legaspi added.

Zoren Legaspi, who does cycling every morning, lauds oatmeal because it is easily prepared.

''Dati kasi, gumigising ako ng 4 am to cook breakfast. It would take so long,'' he said. ''Then I discovered Quaker Instant Oats… [it] makes you feel full throughout the day. And you have energy.''

[Before, I used to wake up at 4 am to cook breakfast. It would take so long.]

Quaker Oats does not only contain iron to help boost immunity, it also has magnesium, protein, fiber, and beta-glucan.

Any serving of Quaker Oats is easy to prepare and versatile enough that you can add fruits for a sweet bowl or savory elements with hints of spice.

There is more than one way to build your immunity and there is more than one delicious way to enjoy it. So, find which oatmeal recipe will work for you and start the day strong.
