Introduction and objectives: In-depth study is presented of the relationship between dietary intake
habits, physical activity (PA), food allergy (FA) and type 2 Diabetes mellitus (T2DM) in physically
active elderlies. Methods: Forty-two elderlies (Mean age: 74.5 ± 4.4 years; Females: 64.3 %),
diagnosed with T2DM and living in Madrid (Spain) participated in the study. Body composition
was measured by dual energy X-ray absorptiometry (Prodigy, General Electric, USA) and
bioelectric impedance (TANITA-BC-418, Japan). Serum IgE against 78 specific European
allergens (sIgE) with 3 food allergy levels (FAL) were determined through line immunoassay
(HELIA, AESKU Group, Germany). PA was measured using the validated long form of the IPAQ.
Dietary intake habits were recorded by means of 24-hour dietary recall interviews. Energy and
nutrients intakes were estimated with the DIAL® software (Alce Ingeniería, Madrid, Spain: 2016).
Results: Average height: 1.56 ± 8.6 m; Average weight: 71.4 ± 10.6 kg; Average BMI: 29.4 ± 4.1
kg/m²; Average body fat: 36.4 ± 7.4 %; Average fat mass: 26.2 ± 7.7 kg; Average bone mineral
density: 1.141 ± 0.1 g/cm². Severe FA were found in 9.5 % of the participants (sIgE ≥ 50.0 kU/L)
corresponding to salmon, tuna, rice and peanut. On the other hand, 45.2 % of the elderlies showed
moderate FA (3.0 < sIgE < 50.0kU/L) including wheat, barley, corn, soy, sesame, egg white,
shrimp, lamb, chicken, onion and orange. Saturated and monounsaturated fatty acids intakes
reflected positive correlations with high and moderate FA including cod, salmon and lamb sIgE
(all p < 0.05). Furthermore, self-declared moderate PA (433.3 MET metabolic equivalent min/day;
IQR interquartile range: 283.4 - 754.1 MET min/day) correlated with moderate and low FA of
tomato, cow's milk and shrimp sIgE (all p < 0.05). Positive correlations were also found for males
with strawberry and chicken sIgE (both p < 0.05). Age correlated positively with peach sIgE but
negatively with shrimp sIgE (both p < 0.05). Conclusions: FA found in Spanish elderlies and
physically active T2DM adults were mostly related to moderate FA of wheat, barley, corn, soy,
sesame, egg white, shrimp, lamb, chicken, onion and orange.

Introducción: El nopal es un alimento ampliamente utilizado en México, debido a sus propiedades
nutricionales, para el tratamiento de enfermedades crónicas. Sin embargo, las pencas grandes y de
alta maduración son difíciles de consumir a pesar de su alto valor nutricional. Una alternativa para
facilitar su consumo es la deshidratación del nopal para la obtención de harina. La harina de nopal
ha sido empleada como fuente de fibra, y tiene efecto hipolipemiante. Objetivo: Evaluar el efecto
