Effect of brown seaweed on plasma glucose in healthy, at-risk, and type 2 diabetic individuals: systematic review and meta-analysis

“…1). This review included 18 RCTs, from which 12 had a crossover design [27][28][29][30][31][32][33][34][35][36][37][38] and 6 had a parallel design. [39][40][41][42] Of the 18 studies, 10 28,29,32-35 involved an acute intervention as an oral glucose tolerance test (OGTT), measuring the intervention's effect on PPG over 2 to 3 h. Five studies 27,30,[40][41][42] conducted only long-term interventions analyzing the effect on FPG.…”

“…In all the included studies, a placebo was used as a control comparator (Table 2). [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] The study populations ranged from 12 to 97 participants. Ten studies [29][30][31][32][33][34][35][36][37][38] were conducted on healthy participants (n ¼ 256) with a normal FPG (<100 mg/dL) and BMI (18.5 and 24.9 kg/m 2 ).…”

A further 6 were carried out on individuals at risk of developing T2DM (n ¼ 357).…”

“…Only 2 studies, Sakai et al (2019) 27 and Kim et al (2008), 39 were conducted on participants with T2DM (n ¼ 48) (Table 2). [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] Twelve studies 27,[30][31][32]34,37,38,[40][41][42]44 investigated seaweed extracts over whole seaweed, with the most common extract being sodium alginate (n ¼ 6). The dosage varied between studies (ranging from 0.072 g to 70 g), mainly depending on the intervention provided (eg, seaweed extract vs whole seaweed).…”

“…30 The other 9 studies monitored the effect of brown seaweeds on PPG in short-term interventions (2 to 3.5 h). 29,[31][32][33][34][35][36][37][38] Similar to van den Driessche et al (2019), 30 Tanemura et al (2014) 33 used the brown seaweed Undaria pinnatifida (Wakame) and its sporophylls (Mekabu). The Wakame meal had no significant effect when compared against a control, whereas the Mekabu meal significantly lowered PPG (P < 0.05).…”
