Many people believe that reducing fat in their diet can benefit their health. However, this misconception can lead to deficiencies in one of the three crucial nutrient groups, affecting cell structure and metabolism processes. In this article, let's explore what fat is and its significance for human health.
What is Fat?
'What is fat' is a commonly asked question. In nutrition, biology, and chemistry, fat (lipid) typically refers to any ester of fatty acids or a mixture of such compounds. It's one of the three essential nutrient groups for human health, along with carbohydrates and proteins.
Lipids can be found in various products and foods such as butter, milk, animal fat, lard, and bacon. This nutrient not only provides energy for bodily functions but also plays a crucial role in cell structure and promotes metabolic processes, including energy storage and thermoregulation.

In addition to understanding what fat is, controlling this group of nutrients also depends on categorizing foods containing good and bad fatty acids, defined as follows:
Healthy Fats
This group consists of unsaturated fatty acids. They remain liquid at room temperature and exist in two forms: monounsaturated and polyunsaturated, which need to be absorbed into the body through diet. They are classified as healthy fats because they have the ability to reduce cholesterol in the blood, limit the risk of arterial plaque buildup, produce good cholesterol for the body, and prevent heart-related issues.

This group comprises two types: saturated fatty acids and trans fatty acids, which solidify at room temperature and lead to the production of bad cholesterol (LDL), increasing the risk of arterial plaque buildup. This is also the main cause of issues such as angina, coronary artery disease, posing dangers to health.

Many people believe that to lose weight, they just need to cut down on this group of nutrients in their diet. However, this is a misconception stemming from a lack of understanding of what fat is and the importance of this nutrient group. Overall, fats consist of two types with both positive and negative impacts on health. In particular, healthy fatty acids should be supplemented through healthy foods to:
Energy Provision
Statistics show that 1g of lipid equals 9 kcal, providing ample energy for the body. Lipid-rich foods play a crucial role in supplying energy for heavy laborers, as well as in replenishing nutrients for the sick, pregnant women, those in postpartum period, and young children. When external energy sources, mainly through temporary food intake, are interrupted or reduced, lipids also support the body's activities by utilizing energy stored in adipose tissue.

Fat serves to help the body transport and absorb essential vitamins such as vitamin A, D, E, K... This enhances health, boosts immune function, fights aging, and protects vision. Consequently, reducing this nutrient group in the diet makes it harder for the body to absorb vitamins than usual.

The composition of fat contains various essential fatty acids that the body cannot synthesize on its own, such as alpha-linolenic acid (in omega-3), linoleic acid (Omega-6)... Therefore, through healthy foods, you can supplement these fatty acids for the body.
In general, omega-3 is often found in seafood, flaxseeds, walnuts, green leafy vegetables, legumes... Omega-6, on the other hand, is abundant in foods such as sunflower seeds, soybeans, peanuts, and rapeseed oil.

As mentioned earlier, unhealthy fats consist of two types: saturated and trans fats. Consuming unhealthy foods can lead to high LDL levels in the blood, which can negatively impact health.
- Saturated Fats: Fatty acids in this group are the cause of increased levels of bad cholesterol (LDL) in the body, leading to heart issues. They are often found in familiar foods such as fatty meats, eggs, skin, dairy products, coconut, cocoa butter, french fries, cookies...
- Trans Fats: These are fats that are hydrogenated during processing, capable of reducing good cholesterol (HDL), increasing bad cholesterol (LDL), and triglyceride levels in the blood. Foods rich in these fats include cookies, pastries, snacks, frozen foods...

Understanding what fat is can help you build a healthy diet, effectively control lipid levels in the body, and minimize the diseases caused by this nutrient group. In general, you should proactively replace foods high in saturated fats with unsaturated fats. This way, the level of good cholesterol in the blood will be maintained stable.
Here are some tips for building a diet and effectively controlling lipids:
- Limit the consumption of red meat per day or per week, opting instead for foods rich in good fatty acids such as fish, plant-based protein, skinless poultry...
- Avoid fast food as they often contain high levels of trans fatty acids.
- For grilled dishes, you can use vegetable oil like rapeseed oil, soybean oil. Additionally, olive oil can be used for cooking or salad dressing.
- Prefer vegetable-based spreads over solid butter.
- Choose healthy snacks, avoiding those high in saturated fats like cookies, french fries...
You should pay attention to limiting the amount of red meat in your diet to avoid introducing harmful fatty acids into your body (Source: Internet)Alongside harmful fatty acids are groups of substances that help produce good cholesterol, preventing heart issues. Therefore, after understanding what fat is and its role, you can control the amount introduced into your body.
