Sweetspire (Itea) is the only plant that accumulates rare sugars d-allulose and allitol. However, no reports have indicated that sweetspire has a beneficial physiological activity in mammalians. We have examined the effect of dietary dried sweetspire powder (SP) on body fat accumulation in rats fed with a high-fat diet. Twenty-four male Wistar rats were randomized into three groups, the control (C), SP, and rare sugar (RS) groups. The SP diet contained 5% SP (contained 0.4% d-allulose and 0.6% allitol in the diet), and the RS diet contained the same amount of rare sugars as the SP diet. All rats were given free access to the experimental diets for 8 weeks. The percentages of intra-abdominal adipose tissue and total body fat were significantly lower in the SP group than in the C group, suggesting that SP has an anti-obesity effect. Furthermore, this anti-obesity effect may be attributed to the rare sugars in SP.
