Dr. Shi Guimei reply Nutrition

Hello Ms.
Li! Regarding your concerns about hyperopia, astigmatism, and hereditary color vision differences, it is recommended that you consult a qualified ophthalmologist.
Improving these conditions through diet may not yield significant results.
As for your persistent cough, it would be best to see a pulmonologist to determine the underlying cause.
In the meantime, try to avoid irritants such as spicy foods (like chili and pepper), nuts (such as peanuts, sunflower seeds, cashews, and walnuts), and cold foods to reduce irritation to your airways.
Additionally, if you smoke, it is advisable to quit.
Wishing you and your family safety and happiness.
Best regards, Dietitian Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

When it comes to maintaining eye health and addressing issues like farsightedness, astigmatism, and hereditary color vision deficiencies, nutrition plays a supportive role, but it is essential to understand its limitations. Here are some nutrition tips for eye health and cough relief based on your questions.

Nutrition for Eye Health
1. Vitamin A: This vitamin is crucial for maintaining good vision, particularly in low-light conditions. Foods rich in Vitamin A include carrots, sweet potatoes, spinach, and kale. Carrots, in particular, are high in beta-carotene, which the body converts into Vitamin A. While consuming carrot juice can be beneficial, moderation is key to avoid excessive intake.

2. Vitamin B2 (Riboflavin): This vitamin helps in maintaining healthy eyes and can prevent conditions like cataracts. Good sources include dairy products, eggs, lean meats, and green leafy vegetables. A balanced diet that includes these foods can help support your nephew's eye health.

3. Lutein and Zeaxanthin: These antioxidants are found in green leafy vegetables and are known to protect the eyes from harmful light. Foods like kale, spinach, and broccoli are excellent sources.

4. Omega-3 Fatty Acids: Found in fish like salmon and sardines, omega-3s are beneficial for eye health and may help reduce the risk of dry eyes and macular degeneration.

5. Hydration: Adequate water intake is essential for overall health, including eye health. Staying hydrated helps maintain moisture in the eyes.

While these dietary changes can support eye health, it is crucial to consult with an eye care professional for specific conditions like farsightedness and astigmatism. These conditions often require corrective lenses or other medical interventions.

Nutrition for Cough Relief
For your persistent cough, dietary adjustments can help soothe your throat and support your immune system:
1. Stay Hydrated: Drinking plenty of fluids, such as water, herbal teas, and broths, can help thin mucus and keep your throat moist.

2. Honey: Known for its soothing properties, honey can help relieve coughs. It can be taken alone or mixed into warm tea.

3. Ginger: This root has anti-inflammatory properties and can help soothe a sore throat. Ginger tea or adding fresh ginger to meals can be beneficial.

4. Avoid Irritants: Certain foods can exacerbate coughing, such as spicy foods, dairy products, and processed foods. It’s best to avoid these if you notice they trigger your cough.

5. Warm Soups: Chicken soup or vegetable broth can be comforting and help keep you hydrated while providing nutrients.

6. Avoid Cold Foods: Cold foods and drinks can sometimes irritate the throat, so opting for warm or room-temperature options may be more soothing.

7. Limit Caffeine and Alcohol: Both can lead to dehydration, which may worsen your cough.

Conclusion
In summary, while nutrition can play a supportive role in eye health and cough relief, it is essential to consult with healthcare professionals for specific conditions. For your nephew, a diet rich in vitamins A, B2, lutein, zeaxanthin, and omega-3 fatty acids can be beneficial, but professional guidance is crucial for managing his eye conditions. For your cough, staying hydrated, consuming soothing foods, and avoiding irritants can help alleviate symptoms. Always remember that dietary changes should complement medical advice and treatment.
