The article talks about what types of peanuts exist and what benefits they bring to the body. Despite the calorie content of this product, it is relevant for consumption during the period of weight loss.
In the article we will tell:
Peanuts are a popular product that has become widespread due to its taste and composition, rich in useful substances.
In stores and grocery catalogs, peanuts are often placed in the “nuts” category, but from a biological point of view, this is not correct. Peanuts are legumes, and their closest relatives are peas and beans, although they are completely different from them. The name "peanut" is much more suitable for peanuts, because its fruits, which we used to call "nuts", like potatoes, ripen underground.
The peanut culture originated in South America and then spread throughout the world.
In the United States, peanuts became widespread in the late 19th century, primarily due to the research of Dr. George Washington Carver, who is called the father of the peanut industry. He discovered and studied the beneficial properties of peanuts:
The ability to restore the quality of depleted soil without the use of fertilizers. Peanuts saturate the soil with nitrogen, while other crops deplete it. This discovery saved many farmers of that time from ruin.
High protein content. This allowed the poor to diversify and enrich their diet, replacing expensive meat with peanuts, which contain high-quality protein.
Now peanuts are cultivated in many agricultural regions of the world, and its largest producer is China, which accounts for more than 38% of the global harvest of unshelled nuts. In Russia, peanuts used to be grown in the southern regions, but now they are not cultivated in our country.
Peanuts have always been widely used in cooking. The bulk of the crop is processed into oil - an excellent odorless product, with its pleasant taste almost as good as the popular olive oil. Nuts are also eaten as an independent dish, added to confectionery in crushed form, creams and pastes, drinks, halva are prepared with it. In the US, peanuts and peanut butter are the most popular nut products. Their consumption is 67% of the consumption of all nuts. And this is not surprising, because peanuts combine an affordable price, high nutritional value and a long shelf life.
But are peanuts so useful and versatile? Are peanuts harmful? Let's figure it out!

Peanuts are very high in calories, you need to remember this. Always balance the health benefits of peanuts against their potential harm.
ProteinYou may hear that peanuts are a high molecular weight protein. This means that peanuts contain more protein than any other nut and are superior to many other plant and animal foods. For comparison, the protein in peas is only 5 g per 100 g, in a chicken egg - 13 g per 100 g, and in cow's milk - 3.4 g per 100 g. Peanuts will be useful for both people who do not consume animal protein and adherents traditional food system.
Fats
Peanuts are a rich source of healthy monounsaturated fats. But why are they useful? And what other fats are there? Let's figure it out!
Fats are divided into unsaturated and saturated. Unsaturated fats are either monounsaturated or polyunsaturated. Monounsaturated fats remain liquid at room temperature and are found in plant foods such as peanuts, olive oil, and avocados. Monounsaturated fats have been shown to lower total cholesterol and “bad” LDL cholesterol while maintaining “good” HDL cholesterol. This is the kind of fat that peanuts are rich in.
Polyunsaturated fats are found in oily fish - salmon and mackerel. Polyunsaturated fats also lower total cholesterol and “bad” LDL cholesterol, but may not have the same beneficial effect on “good” HDL cholesterol.
Saturated fat is found mainly in animal products such as butter, meat, milk, and cheese. At room temperature, it remains solid.

Trans fats tend to increase total cholesterol and “bad” LDL cholesterol, and can also lower “good” HDL cholesterol. There are no trans fats in peanuts and peanut products.
Cholesterol is a fatty compound found only in certain animal products such as meat, eggs, and full-fat dairy products. Peanuts and peanut butter are plant products that do not contain cholesterol.
To sum up, peanuts are a rich source of healthy unsaturated fats and are free of cholesterol and trans fats, which can be harmful to health if consumed in excess.
CarbohydratesPeanuts are a very low-carb food, containing only 9.9 g of carbohydrates per 100 g.
CelluloseGiven that peanuts contain almost no carbohydrates, 100 grams of the product contains 27% of the daily intake of fiber, and this is more than 100 grams of oatmeal! This fact makes peanuts an excellent source of fiber, which is necessary for the proper functioning of the digestive tract and the formation of a feeling of satiety.

The mineral composition of peanuts is amazing!
The smallest content of sodium is 2% of the daily dose. The remaining minerals are present in much higher concentrations and their importance for the body is difficult to overestimate:
Potassium - essential for maintaining water balance, normal blood pressure and blood sugar
Calcium is an essential element for bone formation
Magnesium is an element necessary for all processes in the body, the consumption of which is especially important during stress
Phosphorus - the main material for the structure of brain cells, is necessary for the absorption of calcium
Iron - is involved in the production of red blood cells, in energy generation, is part of many proteins
Zinc - necessary for local immunity of the skin, mucous membranes, accelerates wound healing, prevents skin inflammatory diseases (acne, eczema, neurodermatitis, psoriasis, etc.)
Selenium is necessary for the normal functioning of the immune system and thyroid gland.
Copper - an assistant to enzymes, proteins, is part of a large number of different substances
Manganese - contributes to the normal growth and development of young organisms, is involved in the growth of bones, connective tissue, blood formation, the synthesis of vitamin C, insulin
And all these nutrients are in peanuts!

Peanuts contain all the essential amino acids that cannot be synthesized by the body and must be obtained from food.
One of the most commonly isolated amino acids found in peanuts is the conditionally essential amino acid arginine, which dilates blood vessels, helps lower blood pressure and the risk of chronic disease, and is involved in insulin production.
What else?Phytosterols are a group of natural compounds found in plant cell membranes. Structurally similar to cholesterol, when eaten, they compete with it for absorption in the digestive system, thereby blocking its absorption and lowering the level of cholesterol in the blood. It is believed that the consumption of phytosterols in the recommended amounts reduces total cholesterol by up to 10%, and “bad” LDL cholesterol by up to 14%.
Resveratrol is an antioxidant best known for its anti-aging effects, but also helps with weight loss and reduces the risk of cancer, diabetes, and kidney disease.
Oleic acid (omega-9) and linoleic acid (omega-6) are important for protecting blood vessels from the formation of cholesterol plaques, preventing atherosclerosis and regulating lipid metabolism.
But as with everything, balance is important. For all the benefits of omega-6, its excess is dangerous for health, in particular due to the pro-inflammatory effect that it has on the body.
According to dietary guidelines, a healthy ratio of omega-6 to omega-3 is 5-10/1, but current trends suggest an overabundance of omega-6 in the diet. This is due to insufficient consumption of fish, with a passion for convenience foods, industrial baking, fast food and other sources of fat.
One, even the smallest change in nutrition can significantly affect a person's health.
So, according to research, daily consumption of 30 grams of peanuts or peanut butter can reduce the risk of developing many chronic diseases.
This effect is achieved due to the combined action of beneficial substances that make up peanuts - unsaturated fats, fiber, antioxidants, arginine and magnesium, which play an important role in disease prevention. And all these substances can be obtained by simply adding a handful of peanuts to the diet.
Consider the benefits of peanuts in more detail.

Thus, a clinical study conducted at Purdue University showed that eating about three ounces (80 grams) of peanuts per day significantly increased the intake of magnesium, fiber, folic acid, vitamin E, copper and arginine, which are important for heart health and phytosterols, which contribute to the reduction cholesterol.
Adherence to a Mediterranean diet supplemented with olive oil or various nuts for 5 years has been shown to result in a 30% reduction in CVD risk and a significant reduction in blood pressure compared to controls.

What properties of peanuts help your heart?
Reducing saturated fats and replacing them with monounsaturated fats helps lower cholesterol levels and thereby prevent atherosclerosis. Moreover, this strategy has been shown to help reduce the risk of coronary heart disease. One easy way to implement this strategy is to use peanut butter on toast instead of butter or margarine spreads.
Magnesium, potassium, resveratrol, arginine have a positive effect on lowering blood pressure. But cardiologists recommend eating unsalted peanuts, because with an excess of salt, the harm of roasted peanuts will outweigh the benefits.
Antioxidants (such as vitamin E) help protect cells from the effects of free radicals, one of the causes of cardiovascular disease.
Arginine helps prevent damage to the arteries.
The action of magnesium, vitamin E, arginine, phenolic compounds and fiber help reduce inflammation, and therefore the risk of developing cardiovascular disease.
It is extremely important for people with diabetes to track the glycemic index of foods. Peanuts are a low glycemic index food (level - only 14), which is about half that of other legumes. Low glycemic index foods have also been shown to significantly improve glucose control in patients with type 2 diabetes. Eating peanuts and peanut butter with breakfast has been shown to prevent blood sugar spikes and help suppress appetite during lunch.
This is enough to safely include peanuts in the diet for diabetes.
Peanuts, Alzheimer's and DementiaPeanuts are an excellent source of niacin and a good source of vitamin E, two nutrients that have been shown to prevent Alzheimer's disease and age-related cognitive decline.
One study found that in almost 4,000 people aged 65 and over, dietary niacin slowed the rate of cognitive decline. In another study, 815 people over 65 without Alzheimer's were followed up for almost four years. Those who ate the most vitamin E from foods were found to have reduced their risk of Alzheimer's by 70%.

Oncology is a very complex and extensive topic, and it is impossible to single out any unambiguously anti-cancer products. There are many different studies on the effect of food on the development of cancer, but they are ambiguous.
So, for example, there was no association between the consumption of all types of nuts, peanuts, peanut butter and the risk of developing pancreatic cancer.
However, an analysis of several studies has shown that the highest level of total nut consumption (≥10 g/day) was associated with a 45% reduction in the risk of some subtypes of breast cancer compared to the lowest level of consumption (0 g/day). However, nut consumption was not associated with the incidence of other breast cancer subtypes or the overall risk of this disease.
Thus, despite the presence of antioxidants, healthy fats, phytosterols, and dietary fiber in nuts, a clear relationship between nut consumption and cancer prevention has not yet been established.
Gallstone disease occurs when the gallbladder does not empty properly. One of the risk factors for gallstone disease is being overweight or obese, as well as high triglyceride levels or low levels of “good” HDL cholesterol.
One study of over 80,000 women found that those who ate peanuts and peanut butter five or more times a week reduced their risk of gallbladder disease by 25%.

Of course, this is not about peanuts themselves, but about a full range of useful substances that affect cholesterol levels, which means they help prevent the development of cholelithiasis. Another proof that eating peanuts in moderation has a beneficial effect on the functioning of the whole organism.
Roasted peanuts are considered healthier than raw peanuts. Is it so? Every time, asking the question “what is more useful?” First you need to understand “why?”. What effect do you want?
Salted peanuts are not the healthiest option, especially for those with a high risk of heart disease.
Roasted in a dry frying pan or oil with a high smoke point, peanuts are considered healthier than raw peanuts, but they are higher in calories. However, it contains heat-activated antioxidants and is less likely to harbor pathogens that can be found in raw peanuts.
Raw peanuts have fewer calories than roasted peanuts. And perhaps this is important to you if you are on a diet and control the overall level of caloric content of the diet. But, unroasted kernels are slowly digested and can cause problems with the gastrointestinal tract. Assess the state of your digestive tract if you choose raw nuts.
In addition, the shell of peanut kernels is a strong allergen, and if you are prone to allergies, then you should also give up raw peanuts.
Everything is purely individual, but when assessing the possible risks from eating raw peanuts, we can conclude that for most people, unsalted roasted peanuts are healthier than raw.
Peanuts are very useful, but high in calories, and, like any other products, have contraindications. Therefore, when consuming it, it is important to know the measure.
Regular consumption of peanuts equivalent to 28-30 g (1 serving) 5 times a week is believed to be safe and associated with a significant reduction in the risk of cardiovascular disease.
It is important to remember that since 28-30 g of nuts provides an energy intake of at least 160 kcal, adding this amount to the diet daily without excluding other foods can lead to a calorie surplus and weight gain.
Any benefit from the product is meaningless if you have contraindications to its use. One of the most important contraindications of peanuts is allergy.
Peanuts are one of the most common foods that cause severe allergic reactions. In the case of allergies, the harm of peanuts can be very serious. For years, as a way to prevent food allergies, doctors have recommended not feeding peanuts to younger children. However, new evidence suggests that regularly eating foods containing peanuts in younger children may help prevent the development of peanut allergy. At the same time, there is evidence that higher nut intake in women was associated with a lower risk of allergy in offspring, consistent with the hypothesis that early allergen exposure increases tolerance and reduces the risk of food allergies in children. This topic needs more research, and in any case, you should be careful when eating peanuts. But to exclude it completely for no apparent reason is not worth it.
Peanut allergy is one of the most serious immediate-type hypersensitivity reactions to food in terms of persistence and severity.
According to the American College of Allergy, Asthma and Immunology, peanut allergy symptoms include:
Because peanuts are rich in pro-inflammatory omega-6 fats and low in anti-inflammatory omega-3s, they can cause an imbalanced omega-3 to omega-6 ratio, which is a common problem these days. An imbalance in the intake of these acids increases the level of inflammation in the body and increases the risk of chronic diseases.

"Useful properties of avocado: recipes" MoreWhile peanuts are rich in healthy fats, dietary fiber, and essential micronutrients such as vitamin E, magnesium, and selenium, they can also contain significant amounts of aflatoxins, which are produced by microscopic molds. Peanuts grow on the ground and become damp, causing the formation of mycotoxins or mold. Mold on peanuts can cause the growth of a fungus called aflatoxin, which can affect gut health.
Therefore, it is important to carefully check the appearance of nuts and not store them in places with high humidity. Eating such nuts can have serious health consequences. Thus, a relationship was found between the consumption of aflatoxin and the frequency of liver cancer, the second most common cause of cancer death. Peanuts have been linked to food sensitivities, leaky gut syndrome, and slow metabolism. This is because aflatoxin can actually compete with probiotics in the gut and thus harm the health of the digestive system. This is especially true with non-organic peanut butter. The presence of mold may be why many children develop inflammatory immune responses to peanuts.
Contraindications for certain diseasesPeanuts are contraindicated in gout, a chronic disease that progresses with excessive accumulation of uric acid salts. Peanuts dramatically increase the concentration of uric acid and can lead to another exacerbation of the pathological condition.
Also, salted peanuts are contraindicated in high blood pressure.
Peanuts are a very high-calorie product that is often removed from the diet when losing weight, like other nuts and oils.
But is it right?
In fact, it is possible to cut out all high-calorie foods and lose weight thanks to the created deficit. But will it be possible to save the result? And is this weight loss safe for health?
Of course, the most important tool for losing weight is a calorie deficit. But your body will work better and more efficiently when it receives all the necessary nutrients for life and health along with energy. And an adequate intake of nutrients is especially important when there is a shortage of incoming energy.
When losing weight, it is important to understand that not all calories are equal.
This is counterintuitive, but as people consume more calories and gain extra pounds, the body loses nutrients and becomes deficient.
This is just due to an overabundance in the diet of high-calorie foods that are poor in nutrients, the so-called “empty” calories. Which create a surplus of energy, but do not contain the nutrients necessary for the healthy functioning of the body. As a result, in addition to being overweight, people develop deficiency states. This is one of the reasons why being overweight often goes hand in hand with chronic diseases. For example, people who consume less magnesium are more likely to have elevated markers of inflammation and risk of metabolic syndrome, insulin resistance, diabetes, and heart disease.
Daily consumption of peanuts has been proven to significantly increase fiber, magnesium, folic acid, vitamin E, copper, and arginine.
The 2005 U.S. Dietary Guidelines report recommended that most people choose meals and snacks that are high in nutrients but low to moderate in energy. The report says that what we eat is just as important as how much we eat.
The next most important tool for losing weight is to enjoy food. After all, it is often impossible to save the result of the diet due to its insipidity and lack of emotional saturation with food.
Have you ever been so hungry that you were ready to eat anything that caught your eye? Or, conversely, did you have a refrigerator full of food, but nothing from the available food satisfied you? These 2 situations describe 2 different states:
The ability to recognize hunger and appetite is the most important tool for losing weight and maintaining weight after a calorie deficit.
After all, if you find foods that satisfy not only your hunger, but also your appetite, you will naturally reduce the number of calories consumed and easily be able to maintain the desired deficit, without suffering and anguish.
Peanuts, despite their high calorie content, can be a great part of your weight loss meal plan.
In support of the benefits of peanuts for weight loss - both in terms of nutritional value and in terms of emotional satisfaction, there is a ton of research, here are some of them:
Adding peanuts and peanut butter to your daily diet while managing your caloric intake has been shown to help you stay full and satisfied, have less need for empty calories, and thus keep your overall calorie intake at the right level.
Study: Effects of chronic peanut consumption on energy balance and hedonics
It was found that after eating peanuts regularly for 19 weeks, resting energy expenditure was 11% greater than at baseline.
Another interesting study is comparing the effect of peanuts and potato chips. Study participants were given either peanuts for a snack, after which they were invited to a buffet and measured the amount and type of food they chose. Participants also reported how hungry or satisfied they felt before and after each snack. Participants reported that they felt equally satisfied after each snack, but they consumed far fewer calories after eating peanuts. They consumed 17-21% fewer calories during the buffet and 9-11% fewer calories for four days after snacking on peanuts compared to snacking on potato chips. Based on the findings, the authors concluded: “peanuts are an ideal high-fiber, high-protein,
Study: Lower energy intake following consumption of Hi-oleic and regular peanuts compared with iso-energetic consumption of potato crisps
Thus, you can safely include peanuts or peanut butter as a nutritious addition to your diet. The main thing to remember about the allowable quantities.
The allowed daily amount of peanuts in the absence of contraindications is a handful of about 30 grams or 2 tablespoons of peanut butter.
It is especially important for children to get enough nutrients for growth and development. But is it true in most cases? Unfortunately no.
Often, children eat without a regimen, may not consume enough protein and snack on “empty calories” that do not carry any benefit at all and contribute to the development of multiple deficiencies and obesity.
But children's love of snacking is a great way for parents to provide a growing body with everything it needs for proper growth and development. It is important for children to roast peanuts because of the risk of allergies.
To do this, you need to make snacking “smart”. It's something delicious, low in empty calories, rich in vital vitamins and minerals, and gives you a good feeling of fullness.
Peanuts are a great example of a “smart snack”, and there are some interesting studies on this:
Children who ate peanuts or peanut butter at least once a week were less likely to be overweight, consumed more vitamins and minerals, and had lower blood cholesterol levels than children who did not eat peanuts.
Adding peanut butter to vegetables encourages children to eat more vegetables. How did you find out? Two classes of 6th grade children were offered fresh carrots, celery, and broccoli during recess and were allowed to eat as much as they wanted. At the same time, one class was given peanut butter as a sauce for vegetables, and children in the second class were given only vegetables. After four months, the researchers measured the amount of vegetables the children were eating. They found that children who ate vegetables with butter increased their vegetable intake by 31%. And the children who were not offered butter ate far fewer vegetables. Are your kids bad at eating vegetables? Offer them a peanut dip!
The combination of protein and healthy fats helps children feel full and satisfied, get a boost of energy, and at the same time maintain stable blood sugar levels.
The 2005 US Dietary Guidelines draw attention to deficiencies in the typical diet of nutrients such as vitamin A, vitamin E, vitamin C, calcium, magnesium, potassium, and fiber.
USDA data shows that eating a daily serving of peanuts or peanut butter can help children and adults meet their needs for these nutrients.
At what age can you eat peanuts? There is no definite answer to this question.
There is an opinion that peanuts will not benefit children under 3 years old, the children's body will not be able to digest and assimilate it.
Previously, it was recommended to introduce peanuts into the diet of a child as late as possible due to the risk of developing allergies, but according to new data, this practice, on the contrary, can lead to its development.
The use of peanuts by children under the age of 3 years should be under the supervision of a physician.
Peanuts can be of different shapes and colors, depending on the variety. The most important thing to pay attention to when buying is not the shape of the kernels, but their freshness and quality.
If you buy peanuts in a package, then choose options in which you can visually evaluate their contents. You should refuse to buy if:

Peanuts are a unique product. Even a small amount of peanuts in a weekly diet can qualitatively enrich its nutritional composition.
When using kernels, the harm of peanuts and its benefits should be correlated. This is especially true of peanuts when losing weight and with any side effects from its consumption. It is important to consume peanuts in a limited amount, because uncontrolled consumption can easily lead to a calorie surplus and weight gain.
Peanuts contain a huge amount of nutrients that help prevent and reduce the risk of many chronic diseases.
Choose a quality walnut and the type of processing that suits you. The harm of roasted peanuts will outweigh the benefits if you have allergies or gout.
With limited use, the absence of allergies and other contraindications, peanuts will be useful to everyone, even children.
