00:00 Hi friends, there are a lot of questions about kidney regularly.
00:03 You ask me questions when you have a kidney disease or if you want to avoid it to know what foods to eat or not to eat.
00:09 I will answer your questions. Welcome to the Jean-Michel Cohen channel, the channel where we only talk about nutrition and where we never tell you about salads.

00:26 The kidney is one of the two large waste factories of the body.
00:30 That means it's those who are supposed to detoxify our body, assuming that there are toxic substances.
00:35 These toxic substances are either those produced by the forts, or those that we absorb through pollutants and other metals that we consume,
00:43 either by drugs, or when the liver is sick, or when one of our organs is sick.
00:48 But the kidney is a waste factory.
00:51 A kidney, you know, filters about 24 liters a day.
00:56 So it's liquid that gets to the kidney.
00:58 There's a kind of little basin, we call it a basin, with a filter underneath.
01:03 And the filter will hold the water, let the waste through, and then it goes through a little pipe called the urethra,
01:11 and it goes down to the urethra.
01:15 And so it will be eliminated in the form of liquid.
01:19 After the coloration, it is very decisive to know if you are sick with the kidney or not.
01:23 When you drink normally, if you have a too concentrated urine, you can have a kidney disease.
01:28 In short, there are many diseases that can affect the kidney because it is a very fragile tissue.
01:32 The most common diseases on the kidney, of course, there is the kidney calculus.
01:35 It is said to be the most violent pain.
01:37 And it is also said that there is kidney failure, that is, when the kidney is not working well,
01:41 either because it is invaded by a tumor, or because it is destroyed,
01:44 or because we eat so badly that we have "shot" the kidney.
01:48 So we're going to start with the foods that can harm our kidney.
01:51 Everything that will give us arterial hypertension.
01:53 For example, someone who has a very salty diet,
01:56 so salt, but salt through food, not at the seasoning salt level,
02:00 is someone who will end up damaging his kidney because the kidney will filter so much,
02:03 because you will drink a lot, a lot, that you will "use" the machine.
02:07 And so, in the end, the kidney can be damaged.
02:09 Salt, you know where you can find it.
02:11 You find it in the seasoning salt, of course.
02:13 You can find it in cheese.
02:15 You can find it in products like canned foods,
02:18 like industrial soups, like prepared dishes, like meat, like smoked fish,
02:24 and basically all the seasoning.
02:26 So be careful, not too much salt consumption.
02:28 The second thing that is extremely important is an excess of protein consumption.
02:32 Because there are a lot of athletes who consume a lot of protein.
02:36 Proteins are large molecules.
02:41 And the kidney is a filter, like a thread, like what we use when we filter something.
02:47 When you eat too much protein, which are large molecules,
02:50 you will damage the filter.
02:52 So an excess of protein damages the kidney tissue.
02:57 So what are proteins?
02:58 Well, there are proteins, mainly animal proteins.
03:01 In priority, meat, fish, crustaceans,
03:06 poultry, eggs, ham, even dairy products, possibly.
03:11 That means you have to consume it in the allowed dose,
03:14 1 to 1.2 grams per kilo of weight per day.
03:16 When you consume too much, you damage the kidney.
03:18 This was the famous problem of hyperprotein diets.
03:21 So that doesn't mean you don't eat it.
03:22 It means you eat it reasonably.
03:24 But it's a food that needs to be controlled.
03:26 And if you have kidney failure, and that happens,
03:30 I answer the question of those who asked me,
03:32 you have to reduce this amount by two.
03:35 That is, instead of eating 1 to 1.2 grams of protein per kilo of weight per day,
03:39 you have to eat 0.5 to 0.6 grams.
03:42 That means you reduce all your proteins by two.
03:44 The most interesting thing is phosphorus.
03:47 I'll explain why.
03:48 It was actually because when your kidney starts to get sick,
03:53 if you ever eat too much phosphorus-rich food,
03:57 phosphorus will increase in your blood,
04:00 and it will prevent the bones from calcifying.
04:02 So that means you'll have two problems instead of one.
04:04 You'll have, of course, the kidney problem, which starts to get sick,
04:09 and then you'll have a dosing problem.
04:12 The fourth element is much more perverse, it's sugar.
04:15 Why don't we eat too much sugar?
04:17 It's because when you eat sugar, at some point, you clog your arteries,
04:21 because it's a bit like sugar in your pipes.
04:24 If you put sugar in, after a while, it will clog your arteries,
04:27 but it also clogs the pipes.
04:29 Because the first blood vessels that are affected by excessive sugar consumption
04:34 are the very small vessels.
04:36 And in particular, two organs that are easily affected,
04:39 three more precisely, one, the eyes, two, the kidneys,
04:43 that is, there are very small vessels that circulate around the kidneys,
04:47 and thirdly, the extremities of the body, that is, the hands and feet,
04:50 which explains why diabetics, for example, have real pain
04:53 and can have a kind of gangrene, the foot that turns black,
04:57 because the small vessels start to clog.
04:59 Two things that are not food are iodine products.
05:04 When you have medical exams where iodine is injected,
05:07 it's toxic for the kidneys.
05:09 And the second thing is all the anti-inflammatory drugs
05:14 that will also damage the kidneys.
05:16 So be careful with this type of product.
05:18 There are two products that should be avoided,
05:20 it's beans and lentils.
05:22 These are interesting products in the case of a normal diet,
05:24 but if you are afraid for your kidneys, you should eliminate beans and lentils.
05:27 Once I've told you the horrors,
05:29 what are the foods that I tend to favor for my kidneys?
05:33 I'm going to favor drinking, that is, I'm going to try to drink water.
05:37 I'm going to take unsodden water.
05:39 Often, I quote Contre-Xéville, in unsodden water,
05:42 you have to try to take water that is not too rich in sodium,
05:44 precisely to counterbalance what I'm telling you,
05:47 that is, a high-sodium diet is not good for your kidneys.
05:51 The second thing, it's getting closer, is fruits and vegetables.
05:54 There are two things that are interesting in fruits and vegetables.
05:56 The first thing is hydration, as usual,
05:58 but it's also our main suppliers in minerals and vitamins.
06:02 So, to prevent a kidney from getting sick,
06:04 you have to give it enough vitamins and minerals
06:06 without necessarily taking them in other products,
06:09 such as solid products.
06:11 When they are in water in the form of fruits and vegetables,
06:14 it's really interesting.
06:16 I know that we put fruits and vegetables in all the sauces,
06:18 but it's really interesting.
06:20 And on top of that, they have an anti-inflammatory effect,
06:22 since only proteins are inflammatory.
06:24 The third category of products is fats, good fats, omega-3s.
06:29 They have two functions in these cases.
06:31 The first function is that they nourish all the cells.
06:33 And the second function is that they prevent the arteries from getting saturated.
06:37 So, the good fats, you know them,
06:39 are salmon, oleagins,
06:43 so it's worth consuming a little more of them.
06:45 And the fourth thing is what I just told you,
06:48 certain seeds.
06:49 For example, to limit blood hypertension,
06:51 we know that a 20 to 30 gram ration of nuts per day,
06:54 even if I know it's a richer product,
06:56 it limits the risks of hypertension.
06:58 So, taking a little bit of it every day,
07:01 it can help improve kidney function.
07:03 For omega-3s, there's a product I love,
07:05 because it's rich in omega-3s,
07:07 but at the same time it's tasty in terms of consistency and taste,
07:11 it's avocados, of course.
07:12 So, that means, here's a little example of a diet.
07:15 I eat fatty fish, I take a little bit of avocado,
07:18 I eat 20 grams of nuts per day, that's enough for me.
07:20 I drink at least 2 liters of water per day,
07:22 non-sodium water, and I eat a lot of fruits and vegetables.
07:24 That's what I had to tell you.
07:26 But be careful with everything we're going to tell you.
07:28 There are two situations.
07:29 There's the one I described to improve kidney function,
07:31 and where the precautions are not quite the same.
07:34 You shouldn't mix the two.
07:35 We're doing prevention today,
07:37 so that's why I wanted to make this video.
