Why is vitamin B1 lacking? ——Analysis of causes of deficiency and preventive measures
Vitamin B1 (thiamine) is one of the essential nutrients for the human body and is involved in energy metabolism and nervous system function. However, cases of vitamin B1 deficiency have increased globally in recent years, especially among certain groups of people. This article will combine the hot health topics of the past 10 days, analyze the main causes of vitamin B1 deficiency, and provide scientific suggestions.
1. Common causes of vitamin B1 deficiency
According to recent medical research and health reports, the main causes of vitamin B1 deficiency can be summarized into the following categories:
| Reason type | Specific performance | high risk groups |
|---|---|---|
| Unbalanced diet | Refined grains are the staple food, and there is a lack of B1-rich foods such as whole grains, beans, and lean meats. | Long-term dependence on fast food, picky eaters |
| alcohol dependence | Alcohol interferes with B1 absorption and utilization and increases renal excretion | alcoholics |
| Digestive system diseases | Chronic diarrhea, gastric surgery, etc. affect absorption | Crohn's disease, gastrectomy patients |
| Increased metabolic demands | Pregnancy, breastfeeding, high-intensity exercise, etc. | Pregnant women, athletes |
2. Correlation analysis of recent hot events
In the past 10 days, the following hot topics have been closely related to vitamin B1 deficiency:
1.“Internet celebrity weight loss method” causes malnutrition: An extreme low-carbohydrate diet popular on a social platform was exposed as causing beriberi (vitamin B1 deficiency) in many users, triggering a warning from the medical community.
2.Increasing cases of alcoholic neuritis: Statistics from a tertiary hospital show that after the increase in alcohol consumption in summer, the number of cases of Wernicke's encephalopathy caused by vitamin B1 deficiency increased by 40% from the previous month.
3.Whole grain consumption continues to decline: The latest "White Paper on Chinese Residents' Diet" points out that urban residents' whole grain intake is only 1/3 of the recommended amount, and polished rice and white flour account for too high a proportion of their staple food.
3. Early warning signs of vitamin B1 deficiency
| system | Early symptoms | severe symptoms |
|---|---|---|
| nervous system | Inattention, irritability | Peripheral neuritis, ataxia |
| cardiovascular system | Palpitations after activity | Heart failure (wet beriberi) |
| digestive system | Loss of appetite | Severe weight loss |
4. Prevention and supplementary suggestions
1.dietary modification: You should consume at least 3 foods rich in vitamin B1 every day, such as:
| food | Content per 100g (mg) |
|---|---|
| yeast powder | 6.56 |
| sunflower seeds | 1.48 |
| lean pork | 0.54 |
| whole wheat flour | 0.45 |
2.special population intervention: Pregnant women are recommended to take a daily supplement of 1.4mg. Alcoholics need to inject supplements under the guidance of a doctor.
3.Cooking Notes: Avoid soaking food for a long time, and promote low-temperature cooking methods such as steaming and boiling to reduce the loss of B1 (high-temperature frying will destroy more than 50% of B1).
5. Latest opinions of experts
A recent position paper issued by the Chinese Nutrition Society pointed out that vitamin B1 deficiency in modern people is showing an "invisible" trend, and many sub-health conditions (such as chronic fatigue) may be related to long-term borderline deficiency. It is recommended to increase whole grain intake to 50-150g per day and conduct regular nutritional assessments.
From the above analysis, it can be seen that vitamin B1 deficiency is the result of multiple factors. Today, with the prevalence of highly processed foods and the accelerated pace of life, we need to consciously pay attention to this "low-key" but vital nutrient.
