(HealthDay News) -- Older people are particularly prone to malnutrition because of chronic disease, having to live on a fixed income, or the unmet need to provide their aging bodies with the proper vitamins and nutrients.

Some 3.7 million American seniors are malnourished, the American Academy of Family Physicians estimates. The academy mentions some of the potential side effects:

• Feeling fatigued.
• Losing weight without trying.
• Losing muscle strength.
• Feeling depressed.
• Having memory loss.
• Getting sick frequently.
• Developing anemia.
