A bright, airy overhead flat-lay on a pale oak wooden table in soft morning daylight. At the center, three matching ceramic glasses in a neat row, each holding a creamy shake in a slightly different tone: one warm golden-yellow, one soft sage green-beige, one pure milky white. Beside the glasses, small shallow ceramic bowls hold the raw sources: dried yellow corn kernels, split green peas, and a small pitcher of fresh milk. A few fresh corn husks and a single ear of corn with pale green leaves are arranged diagonally across the left side of the frame, while a sprig of fresh herbs adds a touch of green. On the right, a pair of matte sage-green dumbbells and a rolled linen towel suggest light resistance exercise, placed with calm, editorial restraint. A linen napkin, a wooden scoop dusted with fine powder, and a few scattered kernels add natural texture. The color palette is warm cream, butter yellow, muted sage, and soft white, with gentle natural shadows falling to the lower right. Shallow depth of field, clean negative space at the top for headline overlay, minimalist modern magazine styling, crisp food-photography look, subtle film-like grain, wide landscape composition.

植物性タンパク質が乳由来タンパクと同等の筋肉合成効果を示す

BY DR. GYMBRO · 2026年11月3日

筋肉をつくる際、植物性タンパク質は乳に劣ると考えられてきましたが、高齢者を対象とした新たな臨床試験で、トウモロコシ由来のタンパク質がその常識に挑んでいます。48名の健康な68歳前後の被験者を対象にしたランダム化比較試験では、20 gのトウモロコシタンパク、エンドウ‑トウモロコシブレンド、乳タンパクのいずれもプラセボを大きく上回る筋タンパク質合成（MPS）を促進しました。3つのタンパク質群間に有意差は認められませんでした。レジスタンス運動は全群でMPS応答をさらに増幅させました。投与量や具体的数値、適応対象、利用時の注意点を以下にまとめます。

A landscape editorial photograph of a sunlit kitchen table in soft morning light, styled like a modern wellness journal cover. In the center sits a simple white ceramic bowl of plain Greek yogurt topped with walnuts and blueberries. Beside it are a small glass of water and a matte stone scoop holding a pale powder, with a few loose grains scattered on a light oak surface. To the left, a pair of weathered hands, clearly an older man's with silver hair on the wrist, rests near a neatly folded linen napkin and a slim stainless steel wristwatch. To the right, a pair of modest hex dumbbells in muted sage green sits on a woven rug at the edge of the frame, slightly out of focus, hinting at strength training. In the background, a tall window with sheer curtains lets in warm golden light, and a small potted olive plant stands on the sill. A minimalist analog clock on the wall is softly blurred, suggesting fasting windows without being literal. The palette is calm and earthy: warm cream, oatmeal, sage green, soft terracotta, and pale wood tones. The composition uses generous negative space on the upper left for headline overlay, shallow depth of field, and gentle natural shadows. The style is clean, contemporary, and slightly muted, like a lifestyle magazine or health journal feature, shot on a 50mm lens with soft film-like grain. Calm, thoughtful, and quietly authoritative, with no text, logos, or futuristic elements.

絶食ダイエットにおけるロイシン対タンパク質：高齢男性の意外な結果

BY DR. GYMBRO · 2026年11月2日

ロイシンは「筋肉のマスタースイッチ」と呼ばれ、絶食ダイエット中の高齢者の筋肉維持に有効と期待されています。28日間の交互断食（ADF）を行った61人の高齢男性を対象に、ロイシンとタンパク質のサプリメントを対照群と比較したランダム化試験の結果、全群で筋力・機能・血圧・脂質は改善したものの、サプリメント群はほとんどのアウトカムで有意な優位性を示しませんでした。投与量や対象者、研究の限界について解説します。
