Cancer is undoubtedly the most serious threat one will face on the road to longevity. Over the course of a lifetime, one in two people will get it (yes! that’s no mistake), and one in four will die. Lazy people and fatalists will probably say “eh, genes, nothing can be done about it”, but the truth is that the vast majority of illnesses can be easily avoided.

In the introduction, I mentioned a study showing that adopted children inherit cancer risk not from their biological parents, but from their adoptive parents:

It’s clear that it’s not only the “genes” we got from our parents that determine what kind of health we’ll have, but also – and perhaps even more importantly – the eating habits we learned in our youth. This is not talked about too loudly because… people don’t want to hear it. We prefer to live in blissful ignorance, convinced that nothing depends on us, that we can quietly munch on unhealthy but tasty snacks, some have perfected this and repeat the mantra about “accidental illnesses” between one cigarette drag and another. Of course, there are varieties of cancer that originate mainly in genes, but even in these cases the risk of disease activation can be significantly reduced.

This should be absolutely obvious to anyone who even thinks for a second. An example that even jumps to mind is cigarettes and lung cancer. No one in their right mind would argue that it is “genes” that are responsible for a smoker getting sick, while a non-smoker is healthy?

A very good example is Japan, where the risk of breast and prostate cancer is 3 to 5 times lower than in the U.S., but the same “Japanese with good genes”, when they go to America and adopt the habits there, already have a risk identical to Americans. Apparently, the genes must have changed for them….

There is no way out, you have to change your diet. There is not, has not and will not arise a more effective way to prevent diseases of civilization. I guess, however, there is no point in elaborating on this topic, as everything has already been discussed in the “diet” section. Here I will only list the supplements that affect the degree of risk.

First, what was mentioned in the topic of diet, but it is worth emphasizing again: iodine and selenium. Many studies show that a high supply of iodine protects against the two most popular cancers, breast and prostate, killing one in thirty. At the same time, as many as 80% of inhabitants of my country were deficient in some studies. It has also been shown that those with the lowest levels of selenium have as much as several times higher risk of death from various cancers. Admittedly, clinical trials with supplementation have not yielded such good results, however, the deficiency is certainly harmful, and in some areas soils have very little of it. However, one should not overdo it in the other direction and lead to an excess.

Some herbs have very strong protective properties, especially turmeric, cayenne or ginger. It is worth including them in our kitchen. Of those available in tablets, ginkgo biloba and gotu kola have shown strong properties, but it’s not certain whether this can be taken “just in case”, or whether by chance some side effects will show up after many years. For that, green tea is almost completely safe.

Vitamin D3 is discussed in a separate section, as is K2, here I’ll just mention that it’s worth a look there, in case someone is only interested in the issue of anti-cancer protection and doesn’t want to read the rest of the site.

Zinc is another element whose low levels have been linked to a much higher risk of disease and death. Here it is enough not to have a deficiency, an excess is just as harmful as its absence. Unfortunately, it is very difficult to check how much of it someone has in the body, the tests are imperfect. As a rule, most people have too little of it in their diet, so it’s worth adding those 5-10 mg a day in supplements, or, for example, a larger portion once a week. If a high deficiency is suspected (when, for example, there is a very big improvement after starting supplementation), take very high doses, on the order of 50 mg a day, for a couple of months, taking a break every few weeks and instead taking 2-4 mg of copper a day for a while, as it is flushed out of the body during aggressive supplementation and if you didn’t do this, a deficiency would appear.

An article devoted entirely to zinc:

Some studies suggest that the gym has a fairly pronounced protective effect.

Conjugated linoleic acid had a very strong effect in some studies, but, as usual, it is an open question whether it will not harm healthy people with very long-term use. Similar doubts have been raised about a substance called indole-3-carbinol. Unfortunately, with the current state of medical knowledge, no one can give a definite answer.

Gamma linolenic acid, present in borage oil, had a very powerful effect; in one study, people eating borage had a three times lower risk of stomach cancer. A teaspoon of oil a day should be enough.

A substance called MSM, methylsulfonylmethane, has very promising initial studies, to the point that doses suggested as a supplement to improve overall health, in animal studies, destroyed some tumors with chemotherapy-like potency. It’s hard to judge what the long-term effects of use will be; among friends, the effects have been very positive, but until there are solid clinical trials, there’s no 100% certainty that there won’t be some side effects. The suggested dose is about 1 gram per day.

Vitamin C does not work:
