大人のチアミンの必要性と,加工穀物の強化の継続的な必要性
Lancet (London, England)
|July 12, 1986
まとめ
新しいフッ素測定法により,成人の26%が異常なチアミン状態であることを明らかにした. 濃度ではなく,絶対的な毎日のチアミンの摂取量が高くなったと,チアミンの状態が改善されることが予測され,強化の重要性を強調した.
科学分野:
- 栄養バイオケミストリー
- 公衆衛生 栄養 栄養について
背景:
- シアミン (ビタミンB1) は細胞代謝に不可欠です.
- シアミン状態の評価は,公衆衛生の介入において極めて重要です.
- チアミン状態を評価するための現在の方法には限界があります.
研究 の 目的:
- 成人のチアミン状態の指標として,赤血球トランケトラーゼ (ETK) 活性を評価する.
- 生化学的なチアミンの状態と食事による摂取を相関させるため.
- チアミン強化による公衆衛生上の影響を評価する.
主な方法:
- 度測定法を用いて,赤血球におけるETK活性を測定した.
- 42人の成人 (年齢層別) が血液サンプルを提供し,7日間の食事の評価を完了しました.
- 生化学的なチアミンの状態は,ETK活動によって定義された.
主要な成果:
- 26%の被験者が異常なチアミン状態を示した.
- 生化学的に正常な個人は,異常な個人に比べて,絶対的な毎日のチアミン摂取量が著しく高かった.
- 絶対的なチアミン摂取量 (mg/日) は,カロリーあたりの摂取量 (mg/1000 kcal) よりもチアミン状態のより良い予測指標でした.
結論:
- 度ETK測定は,チアミン状態を評価するための有効な方法です.
- 十分な絶対的なチアミンの摂取は,生化学的なチアミンの状態を維持するために重要です.
- 加工された穀物からチアミン強化を取り除くことは,公衆衛生に悪影響を及ぼす可能性があります.

Carbohydrate Digestion
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...
Carbohydrates: Dietary Sources and Requirements
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...
Proteins: Dietary Sources and Requirements
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...
Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
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 colonic...

Dosage Regimen: Individualization
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...
