まとめ
高血糖負荷 (GL) のような食生活要因は,細菌性陰道炎 (BV) のリスクを高め,高い食生活繊維の摂取は保護的かもしれない. 証拠の質が限られているため,さらなる研究が必要である.
科学分野:
- 婦人科
- 栄養学
- 微生物学
背景:
- 細菌性陰道炎 (BV) は,生殖年齢の女性における一般的な陰道感染症です.
- BVの原因は完全に理解されていませんが,陰性の婦人科の健康結果と関連しています.
- 食中の炭水化物の摂取は腸内および内微生物群に影響し,潜在的にBVリスクに影響する可能性があります.
研究 の 目的:
- バクテリア性陰道炎 (BV) と食事要因との関連を体系的に検討する.
- 具体的には,BVと食中の炭水化物摂取量,糖質指数 (GI),糖質負荷 (GL),総糖質,および食中の繊維との関連を調べる.
主な方法:
- MEDLINE,CINAHL,およびScopusで2022年4月に体系的な文献検索が行われました.
- 含有基準は,女性,栄養摂取量,食事,マクロ栄養素,BV,陰道不活性症に関する研究に焦点を当てた.
- バイアスのリスクは,AXISとCASPツールを使用して,横断的および症例対照研究で評価されました.
主要な成果:
- 4件の研究 (3件は横断的,1件は対照的) が含める基準を満たした.
- 高いGL摂取量とBVとの間で正の関連性が見られた.
- 食物繊維の摂取量とBVとの間には逆の関連性が見られた.
結論:
- 高いGL摂取量はBVのリスクを高め,高い食物繊維摂取量は保護効果がある可能性があります.
- バイアスのリスクは中等から高かった.
- 限られた低品質の証拠は,BVに対するこれらの食事関連性を確認するために注意とさらなる研究を必要とします.

Carbohydrate Digestion
117.3K
Carbohydrate digestion and metabolism break down simple and complex carbohydrates from food into saccharides (i.e., sugars) for the body to use as energy. Carbohydrate digestion starts in the mouth during mastication, or chewing. The masticated carbohydrates remain intact in the stomach. Digestion resumes in the duodenum of the small intestine, where pancreatic alpha-amylase and brush border enzymes of the microvilli convert complex carbohydrates to monosaccharides. Finally, the monosaccharides...

Carbohydrate Metabolism
11.7K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Carbohydrates: Dietary Sources and Requirements
666
Carbohydrates are predominantly obtained from plant sources. With the exception of lactose found in milk and insignificant glycogen amounts in meat, most consumed carbohydrates have plant origins. Monosaccharides and disaccharides, or sugars, can be sourced from fruits, honey, milk, sugar cane, and sugar beets. Grains and vegetables are rich in the polysaccharide starch. Two types of polysaccharides provide fiber: cellulose, which is abundant in many vegetables, forms undigestible roughage or...

Bacterial Flora of the Large Intestine
641
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
413
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
