avje starostnikov | health of the elderly 220 /kg bw/d were 19% and 57% for sarcopenic and non-sarcopenic older adults, re-
spectively. Intakes lower than 1.2 g/kg bw/d amounted to 69% for the sarco-
penic and 89% for the non-sarcopenic group. Greater daily protein intake in
the sarcopenic group was not reflected in the differences in branch chain ami-
no acid (BCAA) (p = .981) or leucine (p = .931) intake between the two groups.

There were no significant differences in daily intake of carbohydrate (p =
.229), fat (p= .583), and saturated fatty acid (p ≥ .24). Other nutrients like n-3 fatty
acid (U = 544, z = -4.099, p < .001), vitamin D (U = 750, z = -2.721, p = .007), vita-
min K (U = 691, z = -3.116, p = .002), vitamin C (U = 843, z = -2.099, p = .036), vi-
tamin B1 (U = 690, z = -3.112, p = .002), vitamin B7 (U = 680, z = -3.189, p = .001),
and vitamin B9 (U = 589, z = -3.798, p < .001) were all lower in the sarcopenic
compared to the non-sarcopenic group. Intakes of all other nutrients did not dif-
fer between the two groups (p ≥ .062). The proportion of individuals whose usu-
al intake of n-3 fatty acid was below the RDA (Reference dietary values DACH,
2004) was 100% in the sarcopenic group and 83.1% in the nonsarcopenic group.
Vitamin D intake was lower than the RDA in both the sarcopenic and nonsar-
copenic group (in 100% and 87.6% of individuals, respectively). Folic acid in-
take was substantially lower than the RDA in the sarcopenic and nonsarcopenic
group (in 100% and 89.9% of individuals, respectively). Thiamine intake was al-
so lower than the RDA in both the sarcopenic and nonsarcopenic group (92.3%
and 53.9%, respectively). Dietary supplement users in nonsarcopenic group was
9 % (supplement: 9 % vitamin D, 4 % n-3 fatty acid, 2 % vitamin C and 1 % vita-
min B), while none of the sarcopenic participants used supplements.
