Food supply in the Mediterranean area has been recently modified by big retail distribution; for instance, industrial retail has favored shipments of groceries from regions that are intensive producers of mass food, generating a long supply chain (LSC) of food that opposes short supply chains (SSCs) that promote local food markets. However, the actual functional role of food retail and distribution in the determination of the risk of developing metabolic syndrome (MetS) has not been studied hitherto. The main aim of this study was to test the effects of food chain length on the prevalence of MetS in a population accustomed to the Mediterranean diet. We conducted an observational study in Southern Italy on individuals adhering to the Mediterranean diet. We examined a total of 407 subjects (41% females) with an average age of 56 ± 14.5 years (as standard deviation) and found that being on the Mediterranean diet with a SSC significantly reduces the prevalence of MetS compared with the LSC (SSC: 19.65%, LSC: 31.46%; p: 0.007). Our data indicate for the first time that the length of food supply chain plays a key role in determining the risk of MetS in a population adhering to the Mediterranean diet.

It is known that patients with rheumatoid arthritis (RA) have a higher risk of coronary heart disease and sudden cardiac death. Abnormalities in cardiac geometry appear to be involved in the setting of the cardiovascular risk, but it has never been specifically investigated in RA. We enrolled 44 patients with RA compared to 131 subjects without RA (normal, N): The RA aged between 18 and 70 years (mean 48.3 ± 2.1), 25 females, BMI 27.6 ± 0.9; N, of equal age (48.6 ± 1.2, n.s.), included 80 females (BMI 26.7 ± 0.2, ns). Cardiac Ultrasounds showed an increase of the diameter of the left ventricle but not in the septum with reduction of relative wall thickness (RWT) in the RA population compared to N. Relative wall thickness inversely correlates with biochemical parameters of inflammatory response (gamma globulin, p < 0.03; F = 5,660) and anti citrullinated peptides antibody (anti-CCP Ab) (p < 0.02; F = 7,1620) We conclude that unfavorable cardiac remodeling can increase cardiovascular risk in patients with RA.
