By mod­u­lat­ing a key marker of in­flam­ma­tion, a daily glass of tomato juice may re­duce waist size, among healthy women. Chronic in­flam­ma­tion of fat tis­sue is a com­mon as­pect of obe­sity. Pre­vi­ous stud­ies have sug­gested that ly­copene, found abun­dantly in toma­toes and tomato prod­ucts, can ben­e­fi­cially af­fect the cel­lu­lar path­way in­volved in the in­flam­ma­tory process. Pei­Min Chao, from China Med­i­cal Univer­sity (Tai­wan), and col­leagues en­rolled 30 women, ages 20­30 years, with a body mass in­dex (BMI) at or over 20, to par­tic­i­pate in a study in which sub­jects ate a nor­mal diet and ex­er­cised as usual, but were given 280 mL of tomato juice (con­tain­ing 32.5 mg of ly­copene) daily for 2 months. Tomato juice con­sump­tion as­so­ci­ated with a 22% de­crease in mono­cyte chemoat­trac­tant pro­tein (MCP­1) – a key marker of adi­pose tis­sue in­flam­ma­tion, as well as a 25% in­crease in adiponectin – a hor­mone that reg­u­lates in­sulin sen­si­tiv­ity. Ob­serv­ing that daily tomato juice sup­ple­men­ta­tion shifted the adipokine pro­file into anti­in­flam­ma­tory, the study au­thors write that: “Th­ese re­sults show that daily tomato juice sup­ple­men­ta­tion re­duces waist cir­cum­fer­ence, as well as serum choles­terol and in­flam­ma­tory adipokine lev­els in young healthy women and that th­ese ef­fects are un­re­lated to body fat changes.” Ref­er­ence Yu-Fen Li, Ya-Yuan Chang, Hui-Chi Hu­nag, Yi-Chen Wu, Mei-Due Yang, Pei-Min Chao. “Tomato juice sup­ple­men­ta­tion in young women re­duces in­flam­ma­tory adipokine lev­els in­de­pen­dently of body fat re­duc­tion.” Nu­tri­tion, De­cem­ber 12, 2014.
