Essential Vitamin Questions: Do You Need Vitamin D and Breakfast? - Nutrition

About vitamins?


Hello, I would like to ask three questions:
1.
Since I work indoors at home and hardly get any sunlight exposure, do I need to take vitamin D?
2.
Is it okay to take a multivitamin like Centrum long-term, or is it better to take it every few days?
3.
I often hear that breakfast is essential, but sometimes I wake up not feeling hungry at all and only start to feel hungry 3-4 hours later, closer to noon.
Should I force myself to eat in the morning, or is it acceptable to wait until I feel hungry? Thank you very much for your answers.

Hello,
1.
Vitamin D is found in many foods, such as eggs, mushrooms, milk, fish, papaya, mango, carrots, spinach, and tomatoes.
It is recommended to maintain a balanced diet, so there is no need for additional supplementation.

2.
If your diet is not well-balanced, it is acceptable to choose a multivitamin that meets the Dietary Reference Intake Standards (DRIS) for the population.
Daily intake is fine as long as it does not exceed the recommended amounts.

3.
Each individual's gastrointestinal condition varies.
The general recommendation to eat breakfast is due to increased activity levels during the day, which requires adequate nutrients for energy.
If you do not experience any gastrointestinal discomfort and your posture is normal, the timing of breakfast should not have a significant short-term impact.
However, regular meals and normal activity are beneficial for overall health.

This response is provided by Dietitian Tsai Hsiu-Wen from Nantou Hospital, Ministry of Health and Welfare.
Wishing you peace and health.

Hello! Thank you for your questions regarding vitamin D intake, multivitamins, and breakfast habits. Let’s address each of your concerns in detail.

1. Vitamin D and Sun Exposure: Vitamin D is crucial for bone health, immune function, and overall well-being. The primary source of vitamin D for most people is sunlight; when your skin is exposed to UV rays, it synthesizes vitamin D. If you are working from home and not getting any sunlight exposure, you may indeed be at risk for vitamin D deficiency. The recommended daily allowance (RDA) for adults is generally around 600 to 800 IU, but some individuals may require more, especially if they have low blood levels of vitamin D. Foods rich in vitamin D include fatty fish (like salmon and mackerel), fortified dairy products, and egg yolks. If dietary sources and sunlight exposure are insufficient, a vitamin D supplement may be beneficial. It’s advisable to consult with a healthcare provider for a blood test to determine your vitamin D levels before starting any supplementation.

2. Long-term Use of Multivitamins: Taking a multivitamin like Centrum (善存) can be beneficial if your diet lacks certain nutrients. However, it’s important to note that while multivitamins can help fill nutritional gaps, they should not replace a balanced diet. If your diet is generally healthy and varied, you may not need to take a multivitamin daily. Some people choose to take them every other day or a few times a week, depending on their dietary intake. It’s essential to follow the recommended dosage on the label and consult with a healthcare professional if you have specific health concerns or dietary restrictions.

3. Breakfast Habits: The idea that breakfast is the most important meal of the day is widely accepted, as it can provide energy and nutrients to kickstart your day. However, individual needs can vary significantly. If you wake up and do not feel hungry for several hours, it’s perfectly fine to listen to your body and eat when you feel ready. Forcing yourself to eat breakfast when you’re not hungry may lead to discomfort or a negative association with eating. That said, if you find that you often skip breakfast and then overeat later in the day, it might be worth experimenting with lighter options in the morning, such as a piece of fruit or yogurt, to see if that helps regulate your appetite.

In summary, if you’re not getting enough sunlight, consider a vitamin D supplement after consulting with a healthcare provider. Multivitamins can be useful, but they should complement a balanced diet rather than replace it. Lastly, listen to your body regarding breakfast; it’s okay to eat when you feel hungry rather than adhering strictly to the conventional wisdom of eating first thing in the morning.
Maintaining a balanced diet rich in fruits, vegetables, whole grains, and lean proteins will provide you with the necessary nutrients to support your health. If you have further questions or specific health concerns, it’s always best to consult with a healthcare professional or a registered dietitian. Thank you for your questions, and I wish you good health!
