 It is nitrates that are the main form in which mineral nitrogen is absorbed by plants from the soil. After absorption, nitrates are included in reduction reactions, the purpose of which is to obtain ammonium ions (NH4 +). A simplified diagram of this process is as follows:

 Why precisely ammonium? It’s simple. Recall that proteins, one of the most important classes of organic compounds, are composed of amino acids. Amino acids, in turn, are nitrogen-containing molecules. To build an amino acid and, accordingly, protein, the body needs nitrogen. It so happens that nitrates containing nitrogen cannot be involved in the synthesis of amino acids, but ammonium can. So the plant has to first absorb the nitrates and then turn them into ammonium. Alas, this transformation is not an instantaneous matter; therefore, nitrates can accumulate in the plant’s body, and we, in turn, eat them.

 Approximately 70% of all nitrates enter the human body from food composed of plants (fresh or canned vegetables) and about 20% with water (especially water rich in nitrates from wells; deep-well drilled water contains much fewer nitrates). The remaining 10% of nitrates a person receives is from animal products and pharmacological preparations. The permissible daily intake of nitrates for a person is set at 5 mg per 1 kg of body weight.

 Once in the human body, nitrates are converted into nitrites – particularly dangerous anions that oxidize hemoglobin iron. Oxidized hemoglobin (methemoglobin) is unable to transport oxygen. As a result, oxygen deficiency of tissues and organs (hypoxia) develops and in particular, pernicious hypoxic state for cells of the nervous tissue and heart muscle. The accumulation of 20% methemoglobin in the blood is dangerous to our life. A prolonged continuous flow of nitrates into the human body can cause destructive changes in the heart, kidney damage, and an increase in the thyroid gland can be observed (nitrates reduce iodine). Nitrates contribute to the development of pathogenic intestinal microflora, as a result of which intoxication states develop. Particularly dangerous is the conversion of nitrates and nitrites to nitroso compounds, which are characterized by a strong hepatotoxic and carcinogenic effect and can provoke the development of cancer of the liver, mammary glands, stomach and even leukemia.

 After the information above, it is somehow even scary to eat any products that are plant-based. But still, plants remain the most important suppliers of vitamins, minerals and bioflavonoids, so excluding them from our daily diet is very unwise. What then should we do?

 It should be noted that plants, according to the localization of the nitrate reduction reaction, are divided into three main groups. Representatives of the first group of the process of nitrate recovery almost completely takes place in the root system, and ammonium or ready-made amino acids are transported to the part above the ground. These plants are the safest to eat. These include peas, blueberries and some other species. The second group is the complete opposite of the first: they accumulate and restore nitrates in the aboveground part, and ammonium and amino acids (sugar beet) are transported to the roots. Finally, the third group is plants in which the reduction of nitrates occurs equally in both the roots and the leaves. These include cereals and vegetables.

 It is also important to note that plants, depending on the species, accumulate nitrates in different quantities. In this case, there is also a three-level classification. Representatives of the first group are species with a high content of nitrates (up to 5 g per kg of plant mass). These include lettuce, cabbage, beets, dill, onion leaves, cantaloupe and watermelon. The second group accumulates nitrates in medium quantities – up to 300-500 mg / kg. This group includes horseradish, cucumbers, carrots, cauliflower, and zucchini. The third group is our favorite because these vegetables accumulate nitrates in minimal quantities (up to 100 mg / kg). They include peas, sorrel, potatoes, tomatoes, and fruit.

 Now that we have become familiar with the basics of the metabolism of nitrates in plants, let’s look at the specific methods of dealing with these “pests”.

 1. The very first and most important thing: before use, plants should be soaked in water for 0.5-2 hours. This is especially true of the vegetables that accumulate nitrates in large and medium quantities. Due to this, plants lose about 30% of all nitrates accumulated in them. Do not forget to drain the “nitrate water” after this procedure.

 2. In deciduous forms (dill, parsley) the degree of accumulation of nitrates decreases from the center to the periphery. Therefore, it is better to throw away the stems of these plants and to use only the leaves.

 3. Nitrates in significant quantities accumulate in the surface membranes of the fruit. Therefore, cucumbers and radishes should be cleaned before use. As for carrots, nitrates are concentrated in the core.

 4. It is not recommended to collect fruit or vegetative parts of plants in the morning or evening. This is due to the reduced activity of nitrate reductase – an enzyme that reduces nitrates. Accordingly, at this time of day, the level of nitrates in plants is especially high. Therefore, it is recommended to collect them in the afternoon (approximately from 11:00 to 18:00 in the summer).

 5. Canning, boiling, pickling, or salting also reduces the number of nitrates in fruit. It is strictly forbidden to eat fresh salted vegetables, as during the first days there is an intensified process of nitrate formation. In this case, vegetables should be kept for about two weeks until ready. It is also not recommended to use brine.

 6. Salads and other vegetable dishes are best consumed freshly prepared: over time, microflora appears in the plant tissues and begins to restore nitrates to nitrites, which we risk eating.

 7. If you yourself grow vegetables, avoid using nitrate fertilizers and try ammonium based ones instead. In this case, ammonium, once in the body of the plant, is immediately included in the synthesis of amino acids. Light is also an important factor: in the case of light deficiency, the level of nitrates in plants increases.

 Avocado is a fruit that can help restore health. Regular consumption of avocados can play an important role in the treatment of many diseases. This is what my blog is about today.

 Daily avocado consumption is a great way to add vitamins, minerals, phytochemicals and dietary fiber to your daily diet. Here are some ways to use avocado:

 Note: always remember, do not heat or cook avocados. This can lead to the loss of antioxidants and other important nutrients that are sensitive to heat.

 Avocados are “super foods” that contain many nutrients and provide many health benefits. The fruit is usually oval or pear-shaped. Avocado flesh is yellow in the middle and green near the skin. The peel is dark green. Avocados that are very dark, bordering on a brownish or black tint, are usually overripe. Therefore, when buying an avocado, special attention should be paid to its color. In addition to this, smaller avocados are more wholesome and better than large and bright green fruits.

 Avocado has a dark green color with a smooth, pleasant and creamy texture. This natural creamy texture of avocado is due to the presence of fat. The pulp in ripe avocados is very similar to cream cheese. Thus, many dishes can be cooked by replacing cream cheese with avocados. When you eat something oily and creamy, you tend to feel less hungry than usual. In turn, an avocado has an oily and delicate flavor that means it is very filling.

 Avocados are classed as tropical fruits because they are grown mainly in tropical areas, especially in hot, humid tropics and semi-tropics.

 Avocado derives its name from the Aztec word ahuacatl, which means egg (due to the shape of the fruit).

 Avocado, also known as Persea Americana, is a member of the laurel family. Remains of seeds found in ancient settlements suggest that avocado was eaten as early as 8000-7000. BC.

 For several thousand years, avocados were only grown in America. But in the 1970s, the avocado industry became huge. Today, the world production of avocados is more than 3.5 million tons.

 In the last decade, many studies have found a wealth of positive effects that apples have on human health. Apples are not delicious but they are also a great fruit to eat for your health. Adding apples to your daily diet is a very simple way to combat oxidative stress, inflammation, diabetes, heart disease, asthma, Alzheimer’s disease and cancer. This is what my post about today.

 Apples can have a very strong antibacterial impact against gram-positive bacteria, such as staphylococcus, epidermis, subtilis bacilli and gram-negative bacteria, and proteu myrabilis. In addition to the apples themselves, apple tree bark also has antibacterial and antimicrobial properties. It was found that both the fetus itself and the cortex inhibit the activity of various bacteria and thus, prevent the occurrence of diseases caused by bacteria and microbes. This property of apples and the tree bark may be associated with an abundance of polyphenols and flavonoids.

 Apples are effective against diarrhea. Apples reduce stool wateriness and its frequency. Thus, apples can be used as an effective tool in the treatment of diarrhea and dysentery. In addition, apples are also useful in the treatment of hemorrhoids, flatulence and vomiting.

 Apples have a bronchodilar effect, that is, they reduce resistance to the breathing process and expand the bronchi and bronchioles. This effect helps in easing breathing and reduces the overall stress caused by lack of air.

 A recent study showed similar effects when using apple extracts with an anti-asthma drug. The effect caused by the apples is explained by the presence of flavonoids, polyphenols, glycosides, saponins, tannins and alkaloids. Thus, it can be said that apples are just as effective as the medicines used in the treatment of asthma, so people with asthma should eat them.

 Carbon tetrachloride is a harmful substance that causes damage to the liver. It produces a lot of free radicals and increases stress due to oxidative stress, which, in turn, causes liver damage.

 Studies have shown that apple pulp helps reduce the production of free radicals and reduces overall oxidative stress. This beneficial effect of apples is due to their high antioxidant potential. Antioxidants present in this fruit, remove free radicals and reduce lipid peroxidation (a process in which free radicals cause lipid degradation and, therefore, cause damage).

 Apples improve liver function and reduce the level of liver enzymes, which usually increase with liver damage. In addition, apples also showed an increase in antioxidant enzymes and an improvement in the overall condition of the liver cells.

 It was found that apples stimulate the phagocytic activity of macrophages, that is, they increase the absorption of foreign bodies, harmful substances and dangerous microorganisms in tissues and blood and, thus, they protect the body and control infections. In addition, apples also increase the sensitivity of B and T lymphocytes (lymphocytes that are involved in the immune response).

 Apples are also useful for people with impaired immune systems, in particular for cancer, HIV and other diseases. Thus, by consuming apples, you can improve your immune system.

 A direct link between apple consumption and asthma has been found. Eating apples improves overall lung function. Flavonoids in apples reduce asthma. People who consumed 5 or more apples per week had significantly more pulmonary ventilationthan people who did not consume apples. In addition, the presence of catenins in apples improves the condition in chronic obstructive bronchitis. Thus, apple consumption is associated with improved respiration and a reduced incidence of asthma and other lung diseases.
