Recent study reveals intermittent fasting's benefits for cardiovascular health
Moscow - Saba:
A recent study has revealed the effect of intermittent fasting on activating platelets, which may contribute to improving cardiovascular health.
According to the Russia Today website, cardiovascular diseases (CVD) are responsible for more than 20 million deaths annually, most of which result from heart attacks or strokes due to blocked arteries.
The main risk factors for these diseases include atherosclerosis, high blood cholesterol levels, and high glucose levels.
All of these factors increase platelet aggregation, which increases the risk of arterial thrombosis and heart disease. Despite the prevalence of antiplatelet drugs, many patients who take these drugs still suffer from heart attacks caused by coronary vascular thrombosis.
Studies indicate that following certain dietary patterns, such as intermittent fasting, can reduce the risk of heart disease. Intermittent fasting involves reducing energy consumption by 60% for two days a week or on alternate days.
Research has shown that intermittent fasting improves heart health by lowering blood pressure, cholesterol, and insulin resistance.
The current study included patients with coronary artery disease (CAD) who were taking aspirin, who were randomly divided into two groups: an intermittent fasting group and a free-feeding group.
The researchers asked the intermittent fasting group to fast every other day and eat freely on the other days. Platelets were isolated from blood samples collected before and after the 10-day experiment.
The experiments were also conducted on mice carrying the apolipoprotein E (ApoE) gene, which were divided into two groups: a free-feeding group and intermittent fasting.
The researchers found that intermittent fasting reduced platelet activation and clot formation in both humans and mice.
Spectroscopic analyses of gut bacteria showed higher levels of the compounds orotate and 3-indolepropionic acid, or IPA, in the intermittent fasting group.
Experiments have shown that IPA inhibits platelet activation and reduces the time to thrombin formation (a protein with strong clotting activity), which is equivalent to the effectiveness of the anticoagulant drug clopidogrel.
It has also been observed that intermittent fasting increased levels of Clostridium sporogenes bacteria in the intestine, which is the bacteria responsible for producing IPA.
Mice treated with this bacteria showed higher levels of IPA in the digestive tract, plasma, and platelets, which led to a decrease in platelet aggregation and a slower formation of clots.
IPA binds to the pregnen X receptor (PXR) in platelets (a nuclear receptor whose primary function is to sense the presence of foreign toxic substances and in response regulate the expression of proteins involved in detoxification and excretion of these substances from the body), which inhibits platelet activation pathways, such as the Src/Lyn/Syk pathway that prevents clot formation.
Experiments have confirmed that blocking these pathways leads to an increase in platelet aggregation, which supports the role of IPA in inhibiting platelet activation.
The study results indicate that intermittent fasting may reduce platelet activation and clot formation in the arteries, which promotes cardiovascular health by changing intestinal bacteria and increasing blood IPA levels. However, further clinical studies are needed to confirm these results and explore the possibility of using intermittent fasting as a treatment for patients with coronary atherosclerosis.

How to Recognize Concussion in Time
Moscow - (Saba): Russian doctor Georgy Tishkin points out that a concussion requires mandatory medical attention. However, not everyone seeks medical help, especially when the symptoms are not obvious. The Russian doctor, as reported by and cited by Russia Today, explains the signs to watch for and how to avoid complications. According to him, people often underestimate this injury, attributing the symptoms to fatigue or stress. However, failure to diagnose and treat it promptly can lead to serious health consequences. The doctor notes that concussion is not always accompanied by loss of consciousness or obvious external damage, so he advises paying attention to the following signs: headache that does not go away even after rest; nausea or vomiting not related to eating; dizziness, coordination problems, or "fog" in the head; photophobia and phonophobia, where even familiar household sounds or dim light become disturbing; memory impairment—difficulty remembering the moment of injury or concentrating; Emotional changes - unexplained anxiety, crying, and sudden mood swings. He says, "If these symptoms appear after a blow to the head, a fall, or a car accident, don't delay seeing a doctor, because even a mild concussion requires close monitoring." According to him, failure to receive timely treatment can lead to long-term complications that appear months or even years later. These include: post-traumatic encephalopathy - a chronic brain disorder that causes decreased concentration, hand tremors, and slowed thinking; chronic migraines that are difficult to treat; vascular disorders - high blood pressure, weather sensitivity, and insomnia; and psychological disorders - depression, panic attacks, and emotional instability. The Russian doctor points out that the risk of complications is particularly high in children, the elderly, and those who have suffered repeated injuries. Therefore, if someone suspects a concussion, they should consult a neurologist for a proper examination and prescription of appropriate treatment, as a concussion is not just a bruise, but an injury that requires timely treatment to avoid complications.

Most beneficial foods for strong eyesight
Moscow - Saba: Nutrition experts indicate that it is necessary to eat foods and products rich in various types of vitamins that are beneficial to the retina. According to what was reported by the website of the "Russia Today" channel from the Russian doctor Irina Pisariova, a nutrition expert, Vitamin A is one of the most important nutrients for the health of the retina, as its deficiency leads to what is called "night blindness" that is observed with the onset of darkness. She says: "The body must be supplied with foods that contain Vitamin A on an ongoing basis. For example, the yolk of two eggs contains a daily dose of beta-carotene, which can also be obtained from carrots and sweet potatoes." In addition, it is necessary to eat foods containing Vitamin C, which is also necessary for the retina, such as sweet peppers, gooseberries, citrus fruits, and others. As for Vitamin E, it is one of the powerful antioxidants that reduce the risk of premature aging of tissues. It is found in hazelnuts and Brazil nuts. In general, the expert recommends eating about 50 grams of nuts per day. The Russian expert notes that lutein has a positive effect on the walls of blood vessels. Spinach is rich in this substance, and it is easier to digest when heat treated, that is, the product can be lightly fried or scalded with boiling water. According to her, omega-3 fatty acids are useful for preventing dry eye syndrome. Omega-3 fatty acids are found in sea fish - herring, mackerel, salmon. They are also found in flaxseed oil, seeds and nuts, which she recommends eating 2-3 times a week. In general, the condition of vision is affected by genetic characteristics, bad habits, frequent and prolonged time in front of the computer and phone, especially at night. Therefore, it is recommended to use nutrition as a preventive measure against eye diseases.
