When these research results first came out, scholars didn't quite understand it. Just because something is good for your body, does it mean you should eat a lot of it? It doesn't make sense that the risk increases. However, looking at it the other way around, it makes sense. One of the things used to fight inductive reasoning is reactive oxygen. Reactive oxygen species, which are always seen as harmful in our bodies, actually do good things too. When the inductive system is working, it can actually be disrupted. Is it true that you can get cancer if you take medicine incorrectly? It's still a fact. If you take medicine incorrectly, the risk of cancer increases. It's not that there are many substances that can cause cancer by eating too much of something in our daily lives. There aren't many, but they exist. The most representative ones are beta-carotene for vitamin A and vitamin 2.

I mentioned earlier, so let's also look at Vitamin E. For example, the daily intake varies depending on the research. For example, some indicate 400 International Units (IU) a day, others show 800 IU. If someone consumes 800 IU daily, there could be a higher risk of prostate cancer for some individuals. Observing such effects is challenging to determine if they are directly related to Vitamin E or just a correlation. It's not easy to distinguish. Even if there are research results, one might question the necessity of deliberately consuming such supplements every day. In terms of antioxidants, water-soluble antioxidants are easier to excrete through urine compared to fat-soluble antioxidants.

In the case of fat-soluble vitamins like vitamin A and vitamin E, these substances are well-accumulated, so when consumed in excessively high doses for a long time, the risk of inflammation may increase. When these research results first came out, scientists didn't quite understand it. Just because sulfuric acid is good for the body, it doesn't mean that consuming a lot of it is safe. It may seem unreasonable or even absurd to think that there are risks associated with it, but when you look at it from a different perspective, it makes sense. When our bodies are infected with viruses or when cancer cells develop, they need to fight against bacteria, viruses, and cancer cells. One of the substances used to fight in the immune system is reactive oxygen species. These reactive oxygen species are not always harmful in our bodies; they also do good things. However, if something like an antioxidant is introduced from outside our bodies, it can combine with these reactive oxygen species.

When you put substances in, even if you put in a large amount at once, if that large amount of antioxidants does not come out and continues to act in our body for too long, it can actually interfere with the system that works the reasoning. For example, when we think of oxidants, we often think of substances that rust our bodies, but it's not that they rust our bodies. For example, they may be trying to rust colors or viruses, but they can also interfere. In simpler terms, that's what it means. So, in fact, one interesting research about antioxidants is that when you exercise and go out, you should eat antioxidants to recover quickly. However, in research, it has been shown that if you eat too many antioxidants after exercising, the effects of exercise can be offset. There are research results like this from several studies in the past. Why is that so? Because when you exercise, you exercise.

Using energy, cells like muscle cells, go through a process where they experience slight damage, light damage, and as a result, stress in our bodies increases, oxidative stress increases, inflammation occurs. However, when we exercise moderately and provide such light stress, that light stress acts as a signal, leading to the body undergoing various processes to recover and become healthier. If antioxidant supplements are taken at that time, the signal is turned off by the antioxidants, so the effects of exercise decrease. This is a possible speculation. When considering this, the fact is that antioxidants themselves are not always beneficial; this too can be excessive. Just like with protein, is it always better to eat a lot of protein? For proteins as well, some people, for example

Oh, there are people who focus their diet mainly on protein and fat. For example, some people think that eating only meat is the best for them. There are people who really only consume high-protein foods. In that case, it can put a burden on the kidneys. In the past, the concern was that consuming too many high-protein foods for a long time could lead to the production of a lot of waste and toxins during the process of protein metabolism. The most representative example is that when protein is metabolized, ammonia is formed, which is then converted into urea and excreted. However, it was thought that such processes could burden the kidneys over the course of a year. Now, even theoretical concerns are being raised. If you consume a lot of protein, it is broken down into amino acids and absorbed into the bloodstream, circulating in our bodies.

Stress itself. Yes, so when the concentration of certain amino acids or proteins in the blood increases, it can actually put some burden on the kidneys. In this situation, it doesn't seem very good to continue a high-protein diet for too long. Some people may say they are fine, but in reality, when it comes to health issues, whether it's been 10 years or 20 years, it's hard to know if it's beneficial for health. So, when it comes to diets, no matter what kind of diet you follow, a diet that is truly beneficial for health is not tiresome no matter how long you do it. You can continue without getting tired of it and can eat it again tomorrow. It's a balanced diet. However, for example, if you try a high-protein diet, some people can endure it exceptionally. But in most cases,

After a few months, when you crave sweets or want to eat, when you want to eat rice, when you want to eat carbohydrates, if you end up looking for them, why do you think it's better to ignore those natural signals of the body and not think of them as natural signals? In fact, it's because it's not a proper diet that these phenomena occur, and that's why you end up looking for them. It's like a sweet taste. If you eat something like that in the middle, there are certainly reasons for it. There are outstanding people who only eat protein and endure, but the fact that you can't endure eating high-fat and high-protein for a long time is because humans are omnivores and should eat a variety of foods. And it's not good for the body. If it's good, you can continue, but if it's not as good as you think, it's probably better to think that way. The effects of supplements vary from person to person.

What is the reason for this? There may be cases like this, right? Some people are sensitive, and some are insensitive, so that can happen, right? In my case, for example, when I eat something, the effects don't show well, but side effects easily appear. If I eat something wrong, I might feel itchy. Some people say it's good to eat it, but most of it is not scientifically proven. It's more common to have side effects after eating it. So, the immediate reaction of eating it is not very scientific. Also, some say there are lingering effects, but I don't feel the effects when I eat it. However, persistently eating it for a year or two doesn't really make a big difference. Exercise also, like, around 6 months, 3 months, 6 months.

Even if others don't know, I know, yes, it's the same for me. Changes in the body, those supplements that are said to be good for the body, actually, if you take them, in the long run, you will know in 3 to 6 months, and even shortly, in just 1 or 2 weeks, you can somewhat tell. So, rather than forcing yourself to take something that has no effect on me, it's better to just throw it away quickly if it's ineffective. Because there are so many other things to take. Yes, so clearly, there are individual differences in that aspect. Another thing is the placebo effect, which clearly exists. So what I'm saying is, there are many research results showing that something doesn't have much effect. Someone gave me a gift, but it's expensive, so I eat it, I feel good. I feel good, and I feel like something will change. But if you think about it, when do you feel good? About 30 minutes to an hour after eating.

It's not that I feel good afterwards, but I start feeling good right when I swallow. What I'm talking about is the placebo effect. I don't think everything works, but that's the placebo effect. Because it hasn't even passed through my mouth yet, it hasn't been absorbed yet, but I already feel good. That's the placebo effect. But there are more cases like that than you think. So, it's better to be a bit skeptical about that. That's why it's important to find the right supplements that work for you. Still, despite that, there are some research results that say, Well, this is okay. The most research is on multivitamins. Research on multivitamins doesn't mean that multivitamins prevent cancer. Because multivitamins can increase or decrease the risk of cancer.

It's not very effective, but just taking a general multivitamin seems to help delay the decline in cognitive function a bit. This is because it is related to vitamin B12. Vitamin B12 is essential for maintaining the health of our nervous system, including the brain and the central nervous system. As we age, the absorption of vitamin B1 may not be as effective, especially for those who do not eat a balanced diet, including enough meat. So, for those who lack vitamin B12, taking a multivitamin can help delay the decline in cognitive function due to the presence of vitamin B in it.

Some researchers think it's not true. So, those who are not confident that they eat a well-balanced diet, taking a multivitamin or something like that could be helpful. And if you take it, you might think that it could help a little bit in terms of functions. Actually, is it better if it's expensive? Expensive things are not always good. That's right. Because if it's expensive, the placebo effect is more significant. For example, in the case of drugs that affect the brain, if the drug is expensive, the effect is better. For example, if you give a Parkinson's disease drug secretly, let's say it costs 1,000 won a month, but you say it costs 10,000 won, then the symptoms improve. There are things related to the brain. But not everything expensive is good. However, in a capitalist society, more expensive things are always.

It's better, right? For example, food is generally better when it's more expensive. So, unless it's a scam, expensive items are made with better quality ingredients. Therefore, even for something like vitamin C, there might be differences in the ingredients. Usually, more expensive ones are better, but in some cases, for example, with vitamin C, personally, I recommend the best one is the 1000mg vitamin C made by a pharmacy or pharmaceutical company. But for other vitamin C products that are marketed as health supplements, they might be more expensive. However, I don't think you necessarily need to consume those because the ones produced by pharmaceutical companies are already priced reasonably, and reputable pharmaceutical companies like UN or other well-known companies produce them properly.

When you look at it this way, what I mean is, for example, British raw materials may make the product more expensive, but the reality is quite vague. It's really ambiguous and gives a bit of this feeling. For example, things like robot vacuum cleaners are often better when made in China. It seems like they don't even produce robot vacuum cleaners in the UK. So, it's necessary to look into which company produces what. In some cases, well-known brands charge higher prices just because of their brand value. Therefore, you need to be selective in these cases. Generally, if something is too cheap or too expensive, you should be a bit suspicious. It's better to find something at a moderate price range and purchase it. For example, in the case of health functional foods, if I talk about prices, in most cases, it doesn't exceed 100,000 won per month.

The amount of money that goes in per month, so, for example, some products, it's not just for a month, it's for two or three months. If you break it down by month, it's generally between 20,000 to 50,000 won. It's mostly around 20,000 to 50,000 won.
