Malnutrition: Impacts and Nutritional Supplement Recommendations

Malnutrition

Hello, my father-in-law is 65 years old and undergoes an annual health check-up, which always shows normal results.
However, since being diagnosed with diabetes 15 years ago, he has been controlling his diet.
Eight years ago, he started a vegetarian diet and has become even more meticulous.
He wakes up at 4 AM to exercise for half an hour, then drinks milk with oatmeal and one unsweetened steamed bun.
At 10 AM, he eats some fruit (for example, six grapes or half an apple) and skips lunch.
After a nap at 10:30 AM, he wakes up at noon to drink very diluted tea (using only a small amount of tea leaves) and eats ten boiled potatoes (simply cooked without any additives).
Around 4:30 PM, he has dinner, consisting only of blanched vegetables (without salt or oil) and white rice (sometimes paired with the unsweetened steamed bun).
He exercises again at 9 PM (practicing Qigong) and goes to bed at 9:30 PM.
Day by day, although his health check-ups show normal results, he has been diagnosed with "malnutrition" in recent years.
We often hope he can take nutritional supplements like Centrum Silver, but he insists that they contain chemical ingredients.
May I ask: 1.
What are the effects of "malnutrition" on the body? 2.
Is there any medical evidence to support the use of nutritional supplements for him? Thank you!

Hello! You are truly a caring daughter-in-law, showing such concern for your father-in-law's diet.
Regarding his dietary intake, based on the meal times and quantities you mentioned, it seems insufficient.
According to the dietary reference intake published by the Department of Health, individuals over 51 years old should consume approximately 1,750 to 2,300 calories.
Currently, your father-in-law's intake appears to be less than 1,600 calories, which could explain his weight loss.

It is important for a diabetic diet to focus on balanced nutrition, ensuring that all six food groups are adequately represented.
Each meal should ideally include grains, protein sources such as fish, meat, eggs, and legumes, as well as vegetables.
Additionally, it is advisable to incorporate dairy and fruits daily to prevent nutrient deficiencies.

Long-term malnutrition can weaken the immune system, making one more susceptible to infections.
Deficiencies in various nutrients can lead to specific health issues; for example, a lack of vitamin B1 can cause beriberi, a deficiency in B2 can lead to angular cheilitis, and insufficient calcium can result in osteoporosis.

For nutrient supplementation, we recommend focusing on natural foods, as they are cost-effective and less likely to contain additives.
Health supplements should primarily address deficiencies due to inadequate dietary intake or increased needs due to illness.
They can be a convenient option when significant supplementation is required.

When choosing health supplements, it is best to select those that are certified, such as those approved by the Department of Health in Taiwan, indicated by a health mark, or those that have received GMP certification, as these are generally safer.
The market is flooded with various health products, so caution is essential when selecting them.
However, remember that health supplements are still food products, and one should not believe the therapeutic claims made in advertisements.
For your father-in-law's nutritional status, I recommend visiting a hospital's nutrition consultation clinic to discuss his situation in detail with a registered dietitian.
This way, you can receive tailored dietary advice based on his specific health condition.
Especially for diabetic diets, individualization is crucial, as not everyone requires the same diabetic meal plan.
I hope your dedication will help improve your father-in-law's nutrition.

This response is provided by Dietitian Tsai Hsiu-Wen from Nantou Hospital, Department of Health.

More Info

Malnutrition is a significant health concern that can affect individuals of all ages, including older adults like your father-in-law. It occurs when a person's diet does not provide adequate nutrients or when the body cannot absorb the nutrients from food properly. In your father-in-law's case, despite his regular health check-ups showing normal results, the diagnosis of malnutrition indicates that his dietary habits may not be meeting his nutritional needs, which can lead to various health issues.

1. Impacts of Malnutrition
Malnutrition can have several adverse effects on the body, especially in older adults. Some of the potential impacts include:
- Weakened Immune System: Malnutrition can impair the immune response, making individuals more susceptible to infections and illnesses. This is particularly concerning for older adults, who may already have a compromised immune system.

- Muscle Weakness and Loss: Insufficient protein intake can lead to muscle wasting, which can affect mobility and increase the risk of falls and fractures. This is critical for older adults, as maintaining muscle mass is essential for overall strength and balance.

- Cognitive Decline: Nutritional deficiencies, particularly in vitamins and minerals, can affect cognitive function. For example, deficiencies in B vitamins, vitamin D, and omega-3 fatty acids have been linked to cognitive decline and increased risk of dementia.

- Fatigue and Low Energy: A lack of essential nutrients can lead to fatigue and decreased energy levels, impacting daily activities and overall quality of life.

- Delayed Wound Healing: Malnutrition can slow down the healing process, making it harder for the body to recover from injuries or surgeries.

2. Nutritional Supplement Recommendations
Given your father-in-law's dietary restrictions and the diagnosis of malnutrition, it may be beneficial for him to consider nutritional supplements. Here are some recommendations:
- Multivitamins: A high-quality multivitamin can help fill in the gaps in his diet. Look for one that is specifically formulated for seniors, as these often contain the right balance of vitamins and minerals needed for older adults.

- Protein Supplements: If he is not getting enough protein from his diet, protein powders or shakes can be an effective way to increase his intake. Whey protein or plant-based protein powders can be mixed with water or added to smoothies.

- Omega-3 Fatty Acids: These are essential for heart and brain health. If he is not consuming enough fatty fish, consider a fish oil or algae-based omega-3 supplement.

- Vitamin D and Calcium: These nutrients are crucial for bone health, especially in older adults. If he is not getting enough from food or sunlight, a supplement may be necessary.

Medical Evidence for Nutritional Supplements
There is substantial medical evidence supporting the use of nutritional supplements in older adults, particularly those who are at risk of malnutrition. Studies have shown that:
- Multivitamins can improve overall health and reduce the risk of chronic diseases in older adults.

- Protein supplementation has been shown to help maintain muscle mass and strength, which is vital for preventing falls and maintaining independence.

- Omega-3 fatty acids have been linked to improved cognitive function and a lower risk of dementia in older populations.

Conclusion
It is essential for your father-in-law to consult with a healthcare professional, such as a registered dietitian or his primary care physician, before starting any new supplements. They can provide personalized recommendations based on his specific health needs and dietary restrictions. Additionally, addressing his concerns about "chemical ingredients" in supplements can be done by discussing the benefits and safety of reputable brands that prioritize quality and transparency in their formulations.
Encouraging a balanced diet that includes a variety of foods, along with appropriate supplementation, can help improve his nutritional status and overall health, allowing him to enjoy his later years with vitality and well-being.
