Hello! The Department of Health, Executive Yuan, commissioned the Academia Sinica to conduct the "Second National Nutrition and Health Status Change Survey" from 1998 to 2002, which has now been completed.
The survey targeted individuals aged 65 and older and school-aged children between 6 to 12 years.
The results of the nutrition survey conducted on elderly individuals aged 65 and above in Taiwan (1,937 participants from household questionnaires; 2,437 participants from physical examinations) indicated that the average intake of Vitamin B1 among older adults has reached the recommended dietary allowance set by the Department of Health, although there is considerable individual variation, particularly among elderly men in central Taiwan who showed less than ideal intake.
Unrefined grains are the primary source of Vitamin B1, and it is recommended that the public choose whole grain foods such as brown rice, germinated rice, and wheat germ as staple food sources.

In the national nutrition surveys over the years, the average intake of Vitamin B2 has consistently been insufficient.
In the surveys conducted from 1993 to 1996 among adults aged 19-64 and the current survey on older adults, the average intake of Vitamin B2 has reached the recommended levels, but individual differences remain.
Notably, the nutritional status of Vitamin B2 is less ideal among men in central Taiwan and the northern municipalities, as well as among women in rural areas of northern and central Taiwan and in the Penghu region.
Smokers also exhibited poorer Vitamin B2 nutritional status compared to non-smokers.
This survey found a correlation between the intake frequency of Vitamin B2 and dairy products, suggesting that the public should increase their consumption of dairy products and milk.

Vitamin B deficiency is a significant public health concern in many regions, including Taiwan. Several factors contribute to this issue, and understanding these can help address the nutritional needs of the population.

1. Dietary Habits: One of the primary reasons for Vitamin B deficiency in Taiwan is related to dietary habits. Traditional Taiwanese diets may lack sufficient amounts of whole grains, lean meats, dairy products, and vegetables, which are rich sources of various B vitamins. For instance, Vitamin B1 (thiamine) is predominantly found in unrefined grains, while Vitamin B2 (riboflavin) is abundant in dairy products. The consumption of processed foods, which often lack these essential nutrients, has increased, leading to a decline in the intake of natural sources of B vitamins.

2. Age and Gender Differences: Nutritional surveys indicate that certain demographics, particularly older adults and specific gender groups, are more prone to deficiencies. For example, studies have shown that older men in central Taiwan have lower intakes of Vitamin B1 compared to their counterparts in other regions. Similarly, women in rural areas often have inadequate Vitamin B2 levels. This disparity can be attributed to varying dietary practices, socioeconomic status, and access to nutritious foods.

3. Lifestyle Factors: Lifestyle choices, such as smoking and alcohol consumption, can also impact Vitamin B levels. Smokers tend to have lower Vitamin B2 levels, which can exacerbate deficiencies. Additionally, high alcohol consumption can interfere with the absorption and metabolism of B vitamins, leading to deficiencies.

4. Health Conditions: Certain health conditions can affect the absorption of B vitamins. For instance, gastrointestinal disorders, such as celiac disease or Crohn's disease, can impair nutrient absorption. Moreover, individuals with chronic illnesses may have increased nutritional needs that are not being met through their diet.

5. Public Awareness and Education: There is often a lack of awareness regarding the importance of B vitamins and their sources. Educational initiatives focusing on nutrition can help improve dietary choices among the population. Many people may not understand the significance of including a variety of foods in their diet to ensure adequate intake of all essential nutrients.

6. Supplementation: While dietary sources are crucial, supplementation can play a role in preventing deficiencies, especially for vulnerable populations. However, reliance on supplements without addressing dietary habits may not be a sustainable solution. Encouraging a balanced diet rich in whole foods should be the primary focus.

In conclusion, the deficiency of Vitamin B in Taiwan is a multifaceted issue influenced by dietary habits, demographic factors, lifestyle choices, health conditions, and public awareness. Addressing this deficiency requires a comprehensive approach that includes promoting healthy eating habits, increasing access to nutritious foods, and providing education on the importance of B vitamins. By fostering a better understanding of nutrition and its impact on health, we can work towards reducing Vitamin B deficiencies in the population.
