Do you sometimes feel sad, lonely, or heavy for no reason? Do you feel like everything is boring? Many of us have had this experience at some point in our lives. This is normal. But did you know that some of the foods we eat can improve our mental health? Today we are talking about something like that. That is the connection between the nutrient Omega-3 and our happiness.
What is Omega-3? Why is it important for our brain?
Simply put, Omega-3s are a type of fatty acid that our bodies need. "Essential" means that our bodies cannot make them on their own and must get them from the foods we eat. These are considered "good" fats.
60% of our brain is made up of fat. So, good fats like Omega-3 are essential for brain cells to be healthy and function properly. Think about it, the nerve cells in our brain exchange messages with each other. For this message exchange (neurotransmission) to happen properly, these cells need to be in good health. Omega-3 helps a lot with this.
Recent studies have found that people in countries that eat a lot of fish have lower rates of depression. This has led doctors to focus more on the link between Omega-3 and mental health. There is now growing evidence that a diet rich in Omega-3 can be particularly beneficial for those suffering from mental health conditions such as depression and bipolar disorder.
What does the research really say?
There have been several studies on this. In one major study, patients with bipolar disorder were given omega-3 supplements. Bipolar is a condition in which the mood alternates between extremes of happiness (mania) and extremes of sadness (depression). After this study, it was seen that the patients who took omega-3 had a significantly reduced frequency of depressive episodes.
American psychiatrist Professor Andrew Stoll, MD, has done extensive research on this. In a study he conducted in 1999, he gave 30 bipolar patients 10 grams of Omega-3 per day. This is the amount found in about 30 cans of tuna! The other group was given olive oil capsules (placebo).
After four months, the results were amazing. Half of the people who took olive oil had relapsed. But of the 15 people who took Omega-3, only two had relapsed . These results are so promising that he is now conducting a larger four-year study with 120 patients to confirm this further.
"We used a very high dose in the original study, but now it seems that 1 to 2 grams of EPA, the main active ingredient in fish oil, per day is sufficient," says Professor Stoll.
What foods are most rich in Omega-3?
Okay, now you're probably thinking, "So what foods contain Omega-3?" Luckily for us, these are easily available and inexpensive foods in Sri Lanka.
| Food type | Special points and tips |
|---|---|
| Oily sea fish | Fish like salmon, mackerel, sardines, and anchovies are the best sources. Try to include one of these fish in your diet at least twice a week. |
| Flaxseed | You can grind these up and add them to your yogurt, salad, or oatmeal. The body absorbs them better when they are ground up than when they are eaten whole. |
| Walnuts | Eating about a handful of walnuts a day is very good. You can eat them plain or add them to salads. |
| Omega-3 rich eggs | Some eggs are made from specially-fed hens and contain more Omega-3. These can be found in supermarkets. |
If you take fish oil supplements...
Sometimes we may not be able to get enough Omega-3 from food alone. In such cases, some people use fish oil capsules. But there is something to be very careful about here.
Not all fish oil capsules on the market are created equal. So it's important to read the label carefully and look at the EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) content. The EPA component is especially important for mental health. Choose a supplement that provides 1-2 grams of EPA per day.
The most important things to keep in mind
With all of this, there are several very important things we need to understand.
1. Omega-3 is not a substitute: If you are already taking medication for depression or another mental illness, Omega-3 is never a substitute for that medication. It can be helpful, but it is not a reason to stop your main treatment. Be sure to talk to your doctor before starting any supplements. These can interact with some medications.
2. Other health benefits: Omega-3s have many benefits not only for the mind, but also for the body. They have been found to help protect against heart disease. It is so proven that even the American Heart Association recommends eating fish like salmon or tuna at least twice a week. Studies have also shown that they can provide some relief from joint diseases like rheumatoid arthritis, intestinal diseases, and some types of cancer.
3. No side effects: There are no major side effects to eating a diet rich in Omega-3. This means that it is very safe. However, some people may experience minor stomach upset and a fishy taste when taking fish oil capsules.
So, if you're feeling a little down and depressed, try adding some Omega-3-rich foods to your diet. It's a good investment for your mind and body. But remember, if your stress is severe and difficult to control, it's best to see a qualified doctor and seek advice rather than suffer alone.
