Nutritional consideration | Dietary Reference Intake (United States and Canada) [25, 26]/Dietary Guidelines for Americans (United States) [27] | UL (United States and Canada) [25, 26] | Indicator of nutritional risk | Potential role in the prevention of metabolic, physical, and psychological dysfunction |

(i) Physical dysfunction prevention (ii) Depressive symptom prevention (iii) Cognitive impairment prevention (a) Reduced homocysteine |
(iii) Vitamin B12 |

Omega 3 |
AI (α-linolenic acid) Males: 1.6 g/d Females: 1.1 g/d |
ND |
Omega 3 index ([sum of 3 omega 3 fatty acids ÷ total phospholipid fatty acids] × 100) Reference range: 1.4–4.9% Increased Risk: <3.2% Omega 6/omega 3 (sum of 6 omega 6 fatty acids ÷ sum of 3 omega 3 fatty acids) Reference range: 5.7–21.3 Increased risk: >5 |
(i) Physical dysfunction prevention (a) Maintenance of muscle mass (b) Reduced inflammation and oxidative stress (ii) Depressive symptom prevention (iii) Cognitive impairment prevention |
RDA = Recommended Dietary Allowance, AI = Adequate Intake, UL = Tolerable Upper Intake Level, AMDR = Acceptable Macronutrient Distribution Range, and ND = not determinable. aBecause older people may malabsorb food-bound B12, it is advisable to meet RDA through foods fortified with vitamin B12 or supplements containing B12.
