Abstract

Background Different foods can modulate cardiometabolic risk factors in persons already affected by metabolic alterations. The objective of this study was to assess, in healthy overweight individuals, the impact of a diet combining multiple functional concepts on risk markers associated with cardiometabolic diseases (CMD).
Methods Fourty-four healthy women and men (50–73 y.o, BMI 25–33, fasting glycemia ≤ 6.1 mmol/L) participated in a randomized crossover intervention comparing a multifunctional (active) diet (AD) with a control diet (CD) devoid of the "active" components. Each diet was consumed during 4 wk with a 4 wk washout period. AD included the following functional concepts: low glycemic impact meals, antioxidant-rich foods, oily fish as source of long-chain omega-3 fatty acids, viscous dietary fibers, soybean and whole barley kernel products, almonds, stanols and a probiotic strain (Lactobacillus plantarum Heal19/DSM15313).
Results Although the aim was to improve metabolic markers without promoting body weight loss, minor weight reductions were observed with both diets (0.9–1.8 ± 0.2%; P < 0.05). CD did not modify the metabolic variables measured. AD promoted significant changes in total serum cholesterol (−26 ± 1% vs baseline; P < 0.0001), LDL-cholesterol (−34 ± 1%; P < 0.0001), triglycerides (−19 ± 3%; P = 0.0056), LDL/HDL (−27 ± 2%; P < 0.0001), apoB/apoA1 (−10 ± 2%; P < 0.0001), HbA1c (−2 ± 0.4%; P = 0.0013), hs-CRP (−29 ± 9%; P = 0.0497) and systolic blood pressure (−8 ± 1%, P = 0.0123). The differences remained significant after adjustment for weight change. After AD, the Framingham cardiovascular risk estimate was 30 ± 4% (P < 0.0001) lower and the Reynolds cardiovascular risk score, which considers CRP values, decreased by 35 ± 3% (P < 0.0001).
Conclusion The improved biomarker levels recorded in healthy individuals following the multifunctional regime suggest preventive potential of this dietary approach against CMD.
