The most important things about Nutrition and diets

Why is a high level of LDL cholesterol a sign of excess Omega-6 in the diet?

LDL particles serve as transport for Omega-6 fats. After transportation, LDL particles are converted into LDL. Therefore, the increase of low-density lipoproteins in the body is merely a consequence of an excess of Omega-6 fats in the diet. More precisely, it is an imbalance between Omega-6 and Omega-3 fats.

Why fish is not only unhealthy but even harmful after being refrozen.

When fish is frozen once, Omega-3 is not completely destroyed. About 75% of Omega-3 remains. Even oxidation due to the presence of oxygen does not significantly spoil Omega-3. However, if the fish is thawed and refrozen multiple times or stored frozen for a very long time, then one can forget about the presence of Omega-3 in it. Moreover, the processes that occur in fish oil make it pro-inflammatory and harmful.

Why is the ratio of Omega-6 to Omega-3 important in the diet?

The higher the ratio of Omega-6 to Omega-3 in the diet, the greater the risk of various diseases. For example, if the ratio is less than or equal to 4, it improves brain function. With a ratio greater than 10 to 1, the risk of developing asthma increases. With a ratio greater than 4 to 1, the risk of osteoporosis and bone fragility increases. If the ratio is less than 2 to 1, the risk of developing breast cancer decreases. At a ratio of 4 to 1 or less, the risk of cardiovascular diseases is reduced by 70%. Also, at 4 to 1 and above, the risk of Alzheimer's disease increases. With a ratio of 1 to 1 or less, collagen synthesis significantly increases. A ratio of 2 to 1 or less suppresses the development of autoimmune diseases, including rheumatoid arthritis. A ratio of 4 to 1 or less significantly improves sleep quality and reduces stress levels. With a ratio of 2 to 1 or less, the risk of developing diabetes decreases (animal study).

Why is it better to buy grass-fed meat?

The most dangerous Omega-6 fatty acid is considered to be arachidonic acid.
It is found in large quantities in animals that were fed with compound feed.
This is particularly why it is recommended to buy grass-fed meat.
In addition, Omega-3 from plant sources is easily converted into arachidonic acid.

Is there evidence of harm from Omega-6 vegetable oils?

According to statistics, in countries that refuse saturated fats in favor of Omega-6 plant fats, there are more cases of cardiovascular diseases and allergies.

For example, Israel is considered the worst country in terms of cardiovascular diseases.

Another example is India.

The worst and best oils in terms of the Omega-6 to Omega-3 ratio.

The worst Omega-6 to Omega-3 ratio is found in cottonseed oil and sunflower oil.
Cottonseed oil has a ratio of more than 200 to 1, while sunflower oil has a ratio of 171 to 1.
The best is flaxseed oil, which has a ratio of 0.7 to 1.
Also, chia oil, perilla oil, and various saturated fats: lard, butter, or beef fat.

How to use turmeric for health benefits.

Curcumin is the main beneficial substance in turmeric. However, the bioavailability of curcumin is very low – about 3%. The most bioavailable form is considered to be a mixture of curcumin with piperine. In this form, the bioavailability increases hundreds of times. Therefore, if you add turmeric to a dish, it is essential to also add black pepper.

How to choose black cumin oil correctly?

If you are buying black cumin oil, make sure it is standardized and contains 3% thymoquinone. Otherwise, it will not have therapeutic effects.

Why are fats beneficial in a low-carbohydrate diet and harmful in a high-carbohydrate diet?

In a low-carbohydrate diet, the ratio of proteins to fats should be maintained at 1 to 2.
In a high-carbohydrate diet, this ratio will lead to atherosclerosis and obesity.
In this case, the only source of fuel for the body is carbohydrates.
Fats are not burned but accumulate.

Why does a low-protein diet lead to blood acidosis?

Low-protein diet leads to blood acidification due to the secretion of the gastrointestinal tract.

Why a carbohydrate breakfast is the path to obesity.

Due to high cortisol levels and high insulin levels in the morning hours, carbohydrate breakfasts are guaranteed to lead to abdominal obesity.

Why does animal protein not acidify, while plant protein does not alkalize the body?

Certain amino acids from protein oxidize the body, while others alkalize it. This does not depend on whether you eat plant or animal protein. Any protein simultaneously oxidizes and alkalizes the body. However, complete protein helps maintain the acid-base balance without shifting to one side.

Why is more ammonia produced from a deficiency of protein in the diet rather than from its excess?

Are you afraid to consume a large amount of protein because the body produces ammonia? When you consume a lot of carbohydrates and little protein, much more ammonia is produced. Due to the protein deficiency, the body starts to break down its own protein, resulting in ammonia being produced twice. The first time it is produced in the tissues, where there is no one to process it. The second time it is produced in the intestines.

Why does the keto diet improve detoxification?

For detoxification, a large amount of protein and alpha-ketoglutarate is needed – a product that is produced during ketosis. Therefore, the ketogenic diet enhances detoxification processes.

Why shouldn't fats be restricted in the diet of a healthy child?

Fuel for a child's growth is fats. If a child eats too little fat, growth slows down, the formation of the nervous system is disrupted, immunity decreases, and problems with cognitive development arise.
There is no need to be afraid that the little one has gained weight - the body is accumulating fat for the next growth spurt.
However, if the child is already insulin resistant due to a high-carbohydrate diet, then instead of growing, they will gain weight.

Why do low-fat high-carbohydrate diets lead to hypoxemia?

A low-fat high-carbohydrate diet leads to disturbances in fat metabolism, a decrease in surfactant production, impaired oxygen utilization, and disrupted gas exchange. All of this results in hypoxemia — a deficiency of oxygen in the blood.

Why does a high-carbohydrate diet increase the risks of COVID-19?

Low-fat high-carbohydrate diet is the main cause of lung diseases and respiratory illnesses, including COVID-19.
It disrupts lung biochemistry and structure, reduces breathing efficiency, creates systemic inflammation, and impairs immune defense. The body becomes more vulnerable to respiratory infections, including severe cases of COVID-19.

Why do low-salt and salt-free diets lead to edema and cardiovascular diseases?

Salt-free diets or the consumption of up to 3.5 g of salt per day lead to sodium deficiency in the body.
As a result, the kidneys have to reabsorb sodium that should have been excreted.
And along with it, excess water is added to the body.
For every 1 gram of reabsorbed sodium, there is 1 liter of water.
This leads to edema and cardiovascular diseases.

Why do sugary drinks lead to dehydration and mineral deficiencies?

The more sugar you consume, the more water is expelled from the body.
Therefore, any sugary drink is a diuretic and leads to the loss of water and minerals.
Hence the recommendation not to drink sweet beverages in heat or during physical exertion.

How to make hydrolyzed protein at home

Hydrolyzed protein can be prepared at home. To do this, it is enough to boil broth from chicken or rooster. However, it should be boiled for at least 8 hours or 3 hours under pressure in a pressure cooker.

Why is breastfeeding better than formula?

According to statistics, breastfed children have higher IQs and better results in cognitive tests than children on formula.

Why does bad cholesterol increase due to a carbohydrate diet?

Bad cholesterol is very low-density lipoproteins and intermediate-density lipoproteins. Good cholesterol is low-density and high-density lipoproteins.
However, if we look at the composition of very low-density, intermediate, and low-density lipoproteins, the only thing that distinguishes them is the amount of triglycerides. The lower the triglycerides, the better the cholesterol.
In other words, if you remove triglycerides from very low-density and intermediate-density lipoproteins, they will turn into low-density lipoproteins, which is good cholesterol.
Thus, it is the excess of triglycerides that makes cholesterol bad. Triglycerides in the body increase due to a carbohydrate diet. On a keto diet, for example, there is always a very low amount of triglycerides in the blood.

Why does an anti-atherogenic diet lead to cardiovascular diseases?

The anti-atherogenic diet prescribed against atherosclerosis is the worst thing that can be.
It restricts cholesterol in the diet but wholeheartedly welcomes vegetable oils rich in omega-6.
And it is omega-6 that leads to cardiovascular diseases and atherosclerosis.

Why is regular consumption of soy harmful?

According to studies on animals, regular consumption of large amounts of soy leads to infertility in the second or third generation. This does not refer to fermented products.

How do Omega-3 fats help with weight loss?

The consumption of omega-3 in large quantities turns off the gene responsible for fat accumulation. That is, it is a natural weight loss. Moreover, our body does not use omega-3 fats for energy at all. It is a structural fat that is not metabolized like saturated fats or carbohydrates.

Why is the intake of only bran pointless?

To increase the number of beneficial bacteria, consuming only bran does not work. Along with bran, a large amount of fats and protein should be consumed. Otherwise, the bran will pass through quickly.

Why is industrial baking harmful?

Commercial baking, semi-finished products, spreads, restaurant cuisine – margarine is used everywhere. Margarine contains nickel, as it is necessary for the hydrogenation process, that is, the production of margarine. Accumulation of nickel in the body leads to severe consequences.

Why does protein nutrition NOT acidify the body?

The belief that all proteins and protein nutrition acidify the body is erroneous because only a portion of amino acids acidifies the body. Only sulfur- and phosphorus-containing amino acids acidify. The other part, amino acids with nitrogen and alkaline groups, alkalize the body. Thus, if one consumes complete protein, the balance of acidifying and alkalizing amino acids is maintained in the body.

Why is it beneficial to drink plenty of water?

The more you drink, the more beneficial it is for the kidneys.
It helps to dilute the blood, reduce plasma osmolality, and lower the risks of hypertension and edema.

Why are complex carbohydrates harmful?

Everyone is already saying that sugar is very bad and harmful.
However, if you compare sugar, for example, with rice, then rice turns out to be worse.
Sugar has a glycemic index of around 58.
Rice, on the other hand, has a glycemic index of 70 and above.
At the same time, if you consume no more than 20-30 grams of sugar, then you eat much more rice – 100 grams or more.
