Can peanuts lower blood lipids?

Peanuts have a dual effect on blood lipids and cannot simply be considered as a food that lowers blood lipids.

Peanuts are rich in unsaturated fatty acids, especially monounsaturated fatty acids, which help reduce levels of low-density lipoprotein cholesterol in the blood while maintaining stable levels of high-density lipoprotein cholesterol. From this perspective, moderate consumption of peanuts is beneficial for regulating blood lipids. Additionally, plant sterols in peanuts can competitively inhibit cholesterol absorption, and dietary fiber helps reduce fat absorption, both of which have positive effects on lipid metabolism.

However, peanuts are high in calories and fat. Excessive consumption, leading to an intake of calories and fat beyond the body's needs, may actually cause an increase in blood lipid levels. In particular, processed forms such as fried or salted peanuts add extra fats and sodium, increasing the burden on the cardiovascular system.

It is recommended to consume no more than 15 grams of plain peanuts per day, along with low-fat, high-fiber foods, to potentially assist in blood lipid control. Relying solely on peanuts to lower blood lipids is not scientifically sound; comprehensive management including physical activity, a balanced diet, and medical treatment is also necessary.

Can people with high blood sugar smoke?

People with high blood sugar should not smoke. Harmful substances in tobacco, such as nicotine and tar, can exacerbate the dangers of high blood sugar in multiple ways.

From a metabolic perspective, nicotine stimulates the secretion of adrenaline, promoting the breakdown of liver glycogen, which leads to elevated blood sugar levels. At the same time, it also inhibits insulin secretion and reduces insulin sensitivity, interfering with blood sugar regulation. Long-term smoking weakens the body's response to insulin and worsens diabetes.

In terms of vascular health, high blood sugar itself can damage vascular endothelial cells, and the harmful substances produced by smoking further accelerate vascular damage, increasing the risk of complications such as atherosclerosis, coronary heart disease, and stroke. This causes cardiovascular diseases to develop earlier and progress more severely. In addition, smoking can impair blood circulation, leading to peripheral vascular disease and nerve damage, which may result in serious complications such as diabetic foot.

To control blood sugar and prevent complications, individuals with high blood sugar must quit smoking. They should also adopt healthy eating habits, engage in regular physical activity, and follow medical treatment plans to effectively reduce health risks and improve quality of life.

How often should a healthy person get tested for hyperthyroidism?

The frequency of hyperthyroidism screening for the general population should be determined according to factors such as age and family history. Generally, it is recommended that healthy adults undergo thyroid function tests every 2–3 years, including indicators such as serum thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3), to facilitate early detection of abnormalities.

For high-risk individuals, the screening frequency should be increased: those with a family history of hyperthyroidism, patients with autoimmune diseases (e.g., systemic lupus erythematosus), individuals experiencing prolonged mental stress or significant emotional fluctuations, and those who have previously received neck radiation therapy are advised to have annual thyroid function tests to detect thyroid dysfunction promptly. Additionally, due to hormonal changes during pregnancy, pregnant women face increased risk of thyroid disorders and should undergo at least 2–3 thyroid function tests during gestation to ensure maternal and fetal health.

Regular hyperthyroidism screening aids in early diagnosis and helps prevent disease progression that could lead to symptoms such as palpitations, weight loss, and exophthalmos (bulging eyes). If symptoms suggestive of hyperthyroidism, such as unexplained palpitations, excessive sweating, or weight loss occur, individuals should seek timely medical evaluation and testing regardless of their scheduled screening cycle, to enable prompt intervention and treatment.

Why is my face yellow even though I don't have hepatitis A, B, or C?

Pale yellowish complexion may result from various factors. Although viral hepatitis such as hepatitis A, B, and C have been ruled out, other potential causes still need to be considered. A yellowish complexion might be physiological, such as from chronic lack of sleep, excessive fatigue, dietary effects, sun exposure, or oily skin. It could also be pathological, such as malnutrition, anemia, depression, liver dysfunction, jaundice, gallstones, or hookworm disease—these conditions may cause metabolic disturbances in the body, thereby affecting skin appearance.

It is recommended that the patient seek medical attention promptly and undergo detailed liver function tests, including serum bilirubin, liver enzymes, alkaline phosphatase, and gamma-glutamyl transferase (GGT) levels, as well as imaging examinations such as ultrasound, CT scan, or MRI to evaluate the liver, biliary tract, and pancreas. Additionally, physicians may recommend more specialized tests, such as liver biopsy or endoscopic retrograde cholangiopancreatography (ERCP), to further clarify the diagnosis.

Multiple gallbladder polyps were found during the physical examination, one of which is approximately 4mm-3mm in size. Is treatment necessary?

Multiples polyps were found in the gallbladder during a physical examination, one of which measures approximately 4mm-3mm. Whether treatment is needed cannot be generalized and must be determined through comprehensive evaluation. In terms of size, this polyp is currently less than 5mm, which is considered small, and carries a relatively low risk of malignancy. Generally, observation is usually recommended initially.

If the polyp grows rapidly—for example, increasing in size by more than 2mm within six months—or if gallstones, cholecystitis are present, along with frequent symptoms such as right upper abdominal pain, nausea, or vomiting, surgical removal is recommended to prevent deterioration. Additionally, if the patient is older than 50 years or has a family history of gallbladder cancer, even small polyps should be treated cautiously with close follow-up and surgical intervention if necessary.

If no aforementioned risk factors exist, it is recommended to undergo ultrasound examination every 6-12 months to monitor changes in the polyps. If the polyps remain stable over time without significant growth, continued observation is appropriate. However, if any abnormal changes occur, prompt medical consultation is advised for the development of an appropriate treatment plan.

Can I eat mung beans during pregnancy?

In general, it is acceptable for pregnant women to consume mung beans in moderation.

Mung beans are rich in protein, dietary fiber, B-complex vitamins, and minerals such as potassium and magnesium. They have effects of clearing heat, detoxifying the body, promoting diuresis, and reducing edema. They are particularly suitable for pregnant women in the second and third trimesters who experience symptoms such as dry mouth and swelling due to internal heat. However, mung beans are relatively cold in nature, and excessive consumption may irritate the gastrointestinal tract, causing abdominal pain or diarrhea. Pregnant women in the early stages of pregnancy, especially those with unstable embryos or a cold constitution, should consume them cautiously.

It is also important to consume mung beans in moderation, as excessive intake may lead to indigestion or bloating. Some individuals may be allergic to mung beans, experiencing symptoms such as rashes and itching. If a pregnant woman experiences any adverse reactions after consumption, she should stop eating them immediately and consult a doctor. If a pregnant woman is taking medications, especially certain tonic medicines that nourish the body with warmth, she should avoid consuming mung beans simultaneously, as this may reduce the effectiveness of the medication.

Pregnant women can safely consume mung beans, but they should ensure moderate intake, thoroughly cook them, and pay attention to their individual constitution and health condition. If there are any questions or special circumstances, it is recommended to consult a healthcare professional for personalized dietary advice.

Can pregnant women eat instant noodles?

Generally speaking, pregnant women are not absolutely prohibited from eating instant noodles, but they should not be considered a regular dietary choice.

Instant noodles are processed foods that are high in calories and salt but low in nutritional value. The noodle cakes are mostly fried, and the seasoning packets contain large amounts of sodium and additives. Long-term consumption not only fails to meet the nutritional needs of pregnancy, such as proteins and vitamins, but may also increase the risks of edema, hypertension, and gestational diabetes. However, if consumed occasionally due to severe morning sickness, poor appetite, or emergency situations, and when consumed with balanced ingredients, they generally will not cause significant harm to the fetus.

If pregnant women choose to eat instant noodles, they should strictly control the frequency and quantity consumed, avoiding eating them for multiple consecutive days. They should modify their consumption methods by prioritizing non-fried noodle cakes, using less or no seasoning packets when cooking, and enhancing nutritional value by adding low-sodium soy sauce, fresh vegetables, lean meat, eggs, and other nutritious ingredients. Pregnant women should also monitor their health conditions and those with gestational hypertension, kidney disease, or weak gastrointestinal function should avoid consuming instant noodles as much as possible to prevent additional strain on the body.

Compared to instant noodles, there are many healthier fast-food alternatives during pregnancy. For example, whole-wheat vermicelli paired with fresh vegetables and lean meat can provide quality carbohydrates while being rich in dietary fiber and protein. Frozen dumplings or wontons with minimal or no additives can be consumed together with leafy vegetables. Instant oatmeal combined with milk, nuts, and fruits can quickly supply nutrients and is easily digested. Pregnancy diets should primarily focus on balanced nutrition and natural, healthy foods. Instant noodles can be consumed occasionally as a temporary alternative but should not replace well-balanced regular meals. When necessary, pregnant women can consult a nutritionist for personalized dietary advice.

Can I eat ice cream during pregnancy?

Generally speaking, it is acceptable to eat ice cream during pregnancy, but consumption should be moderate.

The low temperature and sugar content of ice cream may irritate the stomach or cause blood sugar fluctuations. Extra caution is especially necessary for pregnant women with sensitive digestive systems, high blood sugar levels, or a history of miscarriage. However, during early pregnancy when severe morning sickness occurs, or during the middle to late stages when body heat increases, consuming small amounts of ice cream may temporarily relieve discomfort. The milk content in ice cream can also provide some energy and calcium.

There are three key principles for eating ice cream during pregnancy. First, control the quantity and frequency—each serving should be no more than half a portion, and ice cream should not be eaten on an empty stomach. Second, choose healthier options—opt for low-sugar, low-fat products with simple ingredients, or make homemade fruit yogurt popsicles to reduce the risk of additives. Third, pay attention to physical reactions—if abdominal pain, diarrhea, or abnormal fetal movement occurs, stop consumption immediately and seek medical advice.

Compared to ice cream, there are healthier ways to stay cool during pregnancy. Fresh fruits at room temperature, such as watermelon and strawberries, can provide hydration and vitamins. Homemade sugar-free yogurt or fruit smoothies offer balanced nutrition, and chilled mung bean soup can help relieve summer heat. Pregnancy nutrition should focus on safety and balance; eating ice cream should only be an occasional treat, not a substitute for regular meals or essential nutrients. Pregnant women with special physical conditions should consult their doctors in advance.

Can patients with gallstones eat eggs?

In general, patients with gallstones can eat eggs, but they should do so in moderation.

Eggs are a nutrient-rich food, containing high-quality protein, amino acids, trace elements, and other nutrients. Moderate consumption is beneficial for nutritional supplementation and enhancing immunity in patients with gallstones. However, the yolk contains high levels of cholesterol and lecithin, which may increase the frequency and intensity of gallbladder contractions when consumed in excess, potentially triggering biliary colic or cholecystitis.

Patients with gallstones should also avoid high-fat, high-sugar, and high-salt foods, and instead consume more fiber-rich vegetables, fruits, and whole grains. Maintaining regular eating habits and avoiding overeating are helpful for managing the condition. If the gallbladder has already been removed, eggs have a minimal impact on digestion, but overall fat intake should still be monitored.

In terms of diet, patients should follow the principles of low fat, low cholesterol, and high fiber to maintain good health. If discomfort occurs after eating, consumption should be stopped immediately and dietary adjustments made. Consulting a hepatobiliary surgeon or nutritionist is recommended when necessary.

Can pregnant women eat apricots?

Generally, pregnant women can eat apricots, but should consume them in moderation.

Apricots are fruits rich in vitamin A, vitamin C, vitamin E, potassium, iron, and dietary fiber. Consuming them in appropriate amounts can help supplement nutrients needed during pregnancy. However, they contain organic acids and fructose, excessive intake of which may stimulate gastric acid secretion, causing stomach discomfort or worsening morning sickness. Additionally, apricot kernels contain cyanogenic glycosides. Although the risk is low under normal consumption, one should avoid accidentally ingesting the kernels or consuming excessive amounts that could lead to toxin accumulation.

It is important to eat apricots in moderation because they are warming in nature and contain significant amounts of plant acids and sugars. Overconsumption may lead to heatiness, oral ulcers, dry mouth and tongue, abdominal pain, diarrhea, and potentially elevated blood sugar levels. Pregnant women with special health conditions, such as diabetes or allergic constitutions, should consult their doctors before consuming apricots to ensure safety.

During pregnancy, it is important to maintain a balanced diet, avoid excessively cold, spicy, or irritating foods, and maintain healthy lifestyle habits to support the healthy development of the fetus. Additionally, care should be taken to choose fresh and safe food sources and to follow dietary recommendations provided by healthcare professionals.
