Benefits of Functional Foods

Functional foods that we consume have several benefits for us. Below will be briefly explained the benefits of functional food.

1. Protect Yourself From Disease

It seems that it has become a common thing that functional food is indeed one of our personal protectors in order to avoid various diseases, especially chronic diseases. Not only that, functional food can also be used as medicine when we are affected by an illness.

Apart from medicine, the body needs energy so that our body has the ability to move, so that the disease can be fought well. By protecting yourself from illness, it is the same as making the people closest to you happy.

“Why can functional foods protect us from disease?” That question may often appear for some people, especially those who are not used to consuming functional foods. In functional food there is a substance called “antioxidant”. The molecules in antioxidant substances will protect us from free radicals. Free radicals are substances that can damage cells in the body.

Thus, we should assume that health is the number one thing that needs to be taken care of, so we will try to eat functional food and eat with a regular diet.

2. Keeping the Body Not Deficient in Nutrition

The nutrients in functional foods are very abundant, so that if we consume those foods, the nutrients in the body will be fulfilled. The nutrients found in functional foods, such as vitamins, minerals, fiber, and healthy fats. All these nutrients are beneficial for the body. For example, fiber that can be useful for smoothing the digestion of food, vitamins that are useful as boosters of the body’s immunity, and so on.

If our body suffers from a lack of nutrition, then it is very vulnerable to disease, so it will be difficult to do various daily activities. In fact, some diseases require us to ask for help from others, such as heart, stroke, etc.

Basically, there are many diseases caused by our lack of body nutrition. For example, goiter caused by iodine deficiency, anemia caused by iron deficiency, and many more.

Therefore, if we want to avoid diseases caused by malnutrition, we must get used to consuming functional foods regularly. Even better, we should get used to a healthy lifestyle, such as sports, regulating sleep patterns, etc.

3. Encouraging the Growth and Development of Children

The growth of the child must be observed so as not to experience a delay in growth. If a child experiences growth retardation, then some parts of the body will not function optimally. Body parts that cannot function optimally will make it difficult for a child to do some activities, so they will be “left behind” from children of their age.

Functional foods have nutritional contents that can be beneficial for children’s growth, such as vitamin B12, omega 3, calcium, folic acid, and others. Vitamin B12 and calcium are very good for the growth of children’s bones, the fulfillment of these two nutrients, then the bones will be strong. Omega 3 can improve brain health and intelligence. Folic acid reduces a child’s risk of spinal cord disease, reduces the risk of neural tube defects, etc.

For this reason, every parent should give functional food as soon as they are children, so that the child’s growth will go well. Parents can provide food, such as milk, grains, cereals, etc.

Conclusion

Food or food is the main source in human life because with food, then humans can undergo various kinds of daily activities. Food consumed by humans can be of natural origin or that has gone through the processing process. From wherever the food we consume comes from, we must look at the quality of the food. Not only looking at the quality of food, but the nutrition in a food also needs to be considered.
