二. 成分分析 在SWISSE的官网上,很轻送的找到了成分 EACH CAPSULECONTAINS: CRANBERRY(Vaccinium macrocarpon) powder equiv. fresh fruit
25 g No addedlactose, gluten, yeast, egg or artificial
flavours. 也就是说,成分很简单,就是蔓越梅粉(每粒胶囊包含相当于25g的新鲜蔓越梅),不含乳糖,面筋,酵母,鸡蛋或人工香料等。 我们来看看蔓越梅长什么样儿 这么一个小小的水果,每天吃相当于25g新鲜果的果粉,就能预防尿路感染?能治疗妇科病?。。。这太难让人相信了,如果真有这样的效果,蔓越梅岂不成了神药?
三.能预防尿路感染?能治妇科病? SWISSE的产品网页上,列举了蔓越梅的如下好处: ClinicallyTested: Contains PACran(r), a clinically
trialled high-potency cranberry thatis a unique powdered form of
the whole cranberry fruit to help support urinarytract
health. SymptomaticRelief: PACran(r) may help provide symptomatic
relief from the discomfortassociated with recurrent cystitis such
as itching, burning and frequenturination. AntioxidantSupport: Cranberries are high in antioxidants,
which help protect againstpotential free radical
damage. Cranberriespossess anti-adhesion qualities, which help
reduce the adhesion of bacteria tothe urinary tract.
Swisse UltiboostHigh Strength Cranberry has been
formulated based on scientific evidence toprovide a high strength
dose of cranberry in a convenient one-a-day dose. 大意是:蔓越莓对泌尿道健康有帮助;能帮助缓解复发性膀胱炎的一些症状如烧灼感、瘙痒、尿频等;含抗氧化成分,能缓解自由基损伤;能减少细菌对尿道的粘附。。。 哇~这么多的功效,有没有科学依据呢?SWISSE列举了一些已经发表的论文来支持,如下: 1. Howell, A.(2009) Bacterial anti-adhesion activity of
human urine: PACran capsule vsTheracran capsule consumption Marucci
Center for Blueberry and CranberryResearch and
Extension 2. Vidlar, D.(2011) A randomized double blind placebo

可是,经过仔细查找资料,发现,这些研究只是单一的、没有经过临床验证。 先来看维基百科上,对蔓越梅的描述 Urinary tractinfections[edit] Twocomprehensive reviews of available research concluded
that there is no evidencethat cranberry compounds are effective in
preventing urinary tractinfections.[16][17] Phytochemicals[edit] Raw cranberriesare a source of phytochemicals,
particularly polyphenols which are under activeresearch for
possible effects on the cardiovascular system, immune systemand
cancer.[17][18][19] However, there is no confirmation from
humanstudies that consuming cranberry polyphenols provides
anti-cancer or any healthbenefits.[17][19] Ps:以上引用来自https://en.wikipedia.org/wiki/Cranberry 大意是:对现有蔓越梅研究的两个全面审查的结论是: 1)
没有证据表明蔓越莓化合物可以有效地预防尿路感染。[16] [17]
2)
也没有证据表明蔓越莓多酚能抗癌或对其他健康有益。[17]
[19] 世界上的各种研究有很多,就好比,今天有个专家说吃西红柿对身体怎么怎么好,明天又有个专家出来说,西红柿吃多了对身体怎么怎么不好。。。 有些研究站的角度不同,得出来的结论是完全相反的,但是有一点,对于人体使用的产品,一定要经过临床验证有效才行,很遗憾,蔓越梅的功效并没有通过临床有效性测试,因为所谓的功效只能是宣传出来的。
SWISSE列举的科学证据中,提到了一点:蔓越梅中含有丰富的原花青素,对预防尿路感染有效。那么,事实究竟如何呢,继续看资料 Urinary tract infections[edit] Cranberries haveA2-type proanthocyanidins (PACs) and the
less common B-type.[24] A-typelinkages may be important for the
ability of PACs to bind to proteins, such asthe adhesins
present on E. coli fimbriae and were thought to prevent
bacterialinfections, such as urinary tract infections (UTIs).[29]
However, clinicaltrials failed to confirm that PACs,
particularly from cranberries, were analternative to antibiotic
prophylaxis for UTIs. A 2014 scientific opinion bythe European Food
Safety Authority rejected physiological evidence
thatcranberry PACs have a role in inhibiting bacterial pathogens
involved inUTIs.[2] Also, a 2012 Cochrane Collaboration review
concluded that 'cranberry juice cannot currently be
recommended for the prevention ofUTIs'.[30][31] Ps:以上引用来自https://en.wikipedia.org/wiki/Proanthocyanidin 大意是:临床试验未能证实,原花青素(蔓越梅),能作为尿路感染预防性使用抗生素的替代品。另外,2012年Cochrane协作审查的结论是“酸果蔓汁目前不能推荐为预防尿路感染”。[30]
[31] ok,现在尘埃落定了,SWISSE的蔓越梅并没有预防尿路感染的功能,也没有治疗妇科疾病的功效。。。它,只是个蔓越梅果粉而已。按照营养的标准,它只是包含下列营养成分:
