When you talk about vitamins, you probably always hear about vitamins A, B, C, and D. But have you ever heard of 'Vitamin F'? Although many people don't know, this is something that is essential for the healthy functioning of our body. But the surprising thing is, even though it is called 'Vitamin F', it is not actually a vitamin. So what is this? Let's talk about it in detail and simply.
What exactly is 'Vitamin F'?
Simply put, vitamin F is not a vitamin, but a combination of two types of fats. These are alpha-linolenic acid (ALA) and linoleic acid (LA). Both of these fatty acids are essential for our bodies. This means that our bodies cannot make them on their own, and we must obtain them from the foods we eat.
Both of these fatty acids belong to a group called polyunsaturated fatty acids. They perform many important functions in our bodies. They protect nerves, help blood clot, and are essential for our muscle function.
So why did these two types of fats get the name 'vitamins'? The story begins in 1923. When these two substances were first discovered, scientists mistakenly identified them as vitamins. Even though it was proven a few years later that they were actually fats, the old name 'vitamin F' persisted among people.
Nowadays, doctors refer to both ALA and LA under the general name 'essential fatty acids.' These are divided into two main families.
- Omega-3 fatty acids: ALA belongs to this group.
- Omega-6 fatty acids: LA belongs to this group.
What are the health benefits of vitamin F (that is, these fatty acids)?
These essential fatty acids are important for everything from our body's cells to our brains. Let's take a look at some of the main benefits.
1. Brain and nervous system health
Our brain contains a large amount of polyunsaturated fatty acids. These help generate the energy needed to think and work every day. These essential fatty acids are especially important for the development of the brain of a fetus and a small baby. Without enough of these, the brain's nerve cells (neurons) and the connections between them (synapses) do not develop properly.
2. Heart health
Research has found that eating a diet rich in ALA and LA can reduce the risk of coronary heart disease and death from heart disease. Also, replacing saturated fatty acids like animal oils with these polyunsaturated fatty acids can reduce bad cholesterol levels in the blood. Imagine how good it would be for your heart if you used something like canola oil instead of butter when cooking.
3. To preserve memory and intelligence
It's normal for memory to decline as we age, but there's strong evidence that eating a diet rich in omega-3 fatty acids (like ALA) can help prevent this age-related memory loss and cognitive decline.
4. Relief from Rheumatoid Arthritis
Rheumatoid arthritis is a condition that causes swelling, stiffness, and pain in the joints. Some research has shown that a diet rich in omega-3 fatty acids can reduce inflammation in the body of these patients. This may reduce joint pain and stiffness.
How much of these do we need? How can we get them?
A healthy person usually gets the required amount of these fatty acids from their daily diet. Therefore, there is no upper limit on how much they should be taken. However, if you have a health problem, such as heart disease, your doctor may recommend a specific dose.
The most important thing is that since our bodies cannot produce these fatty acids on their own, we must definitely include foods that contain them in our diet.
There are many foods that contain omega-3 (ALA) and omega-6 (LA) fatty acids. ALA is found mostly in plant foods. LA is found in vegetable oils, nuts, meat, and eggs.
See the table below to see which foods are rich in these essential fatty acids.
| Food category | Examples |
|---|---|
| Vegetable oils | Soybean oil, canola oil, flaxseed oil, safflower oil |
| Types of nuts and seeds | Chia seeds, flax seeds, sunflower seeds, walnuts |
| Green vegetables | Spinach, broccoli, Brussels sprouts |
| Types of fish | Oily fish like salmon and albacore tuna |
| Other | Eggs, meats |
It's not that hard to add these things to your diet. For example, you can add some flax seeds or walnuts to your salad. If you can eat oily fish at least two days a week, that's great too.
Take-Home Message
- 'Vitamin F' is not a vitamin, it is actually a combination of ALA and LA, two essential fatty acids that our body needs.
- Since our bodies cannot produce these fatty acids on their own, we must obtain them from the foods we eat.
- These are very important for brain development, heart health, and overall health.
- These fatty acids are abundant in foods such as vegetable oils, nuts, green vegetables, and oily fish.
- If you have a medical condition, it is very important to consult your doctor about taking these as supplements or changing your diet.
