Gut & Sleep Reset – 腸と睡眠の深い関係 日本語版を読む... English Gut & Sleep Reset – Why a Healthy Gut Improves Your Sleep Many people try melatonin, supplements, or sleep apps — but still wake up tired. One overlooked reason is the gut. The connection between your digestive system and sleep quality is stronger than most people imagine. In this article, you’ll learn how the gut–brain axis affects your sleep and practical ways to improve both at the same time. How Your Gut Affects Your Sleep Your gut produces up to 90% of the body’s serotonin — a hormone that regulates mood and becomes melatonin, the “sleep hormone.” When the gut is inflamed or unbalanced, serotonin production drops, making it harder to fall asleep or stay asleep. The Gut–Brain Axis Explained The gut and brain communicate constantly through the vagus nerve. If your gut microbiome is imbalanced, it sends stress signals to the brain, increasing anxiety and disrupting sleep cycles. What Co...

What’s New in AI (2025) — Major Trends to Watch Right Now Artificial Intelligence is evolving faster than ever. In 2025, breakthroughs across generative AI, multimodal models, video generation, and local-AI are reshaping how we live, work, and create. Here’s a clear, easy-to-understand overview of the biggest AI trends you should know about now. 1. Generative AI Goes Mainstream — Text, Images, Video, and Beyond Generative AI is no longer limited to text. Latest tools and models now produce high-quality images, illustrations, even full motion video. This makes content creation faster and more accessible. Creators, marketers, educators — everyone is using AI to generate visuals, scripts, and multimedia. 2. Multimodal Models Are Taking Over 2025 marks the rise of multimodal AI — models that understand and generate across text, image, audio, video, and even motion. These models aren’t just versatile — they’re becoming a new standard fo...

Apples + Carrots: A Surprisingly Poor Food Pairing Apples + Carrots: A Surprisingly Poor Food Pairing Both apples and carrots are healthy and nutrient-rich. However, when eaten together, they can create an unexpected nutrient conflict — especially involving vitamin C and certain enzymes. Why This Combination Is Not Recommended Carrots contain an enzyme called ascorbic acid oxidase . This enzyme can break down vitamin C found in apples. Meaning: • Vitamin C from apples becomes less effective • The antioxidant benefits decrease • The pairing offers fewer immune-support advantages Vitamin C Breakdown The enzyme in carrots actively neutralizes vitamin C when both foods are mixed or digested together. This makes the combination less nutritionally efficient. Who Should Avoid This Pairing? • People focusing on improving immunity • Those who rely on vitamin C–rich fruits • Anyone drinking apple-carrot juice daily Better W...

Papaya + Lemon: A Nutrient-Blocking Combination You Should Avoid Papaya + Lemon: A Nutrient-Blocking Combination You Should Avoid Papaya is rich in enzymes and vitamins, while lemon is high in acidity and vitamin C. Both are healthy on their own — but when mixed together, this pairing may actually reduce nutrient absorption and irritate the stomach. Why This Combination Isn’t Ideal Papaya contains papain , a digestive enzyme that helps break down proteins. However, the strong acidity of lemon can weaken the activity of papain. This means: • Nutrients from papaya may not be absorbed efficiently • Digestion may slow down • Sensitive individuals may feel mild acidity or discomfort Enzyme Neutralization Papain works best in a mildly alkaline environment. But lemon shifts the stomach toward an acidic state, reducing the natural benefits of papaya’s enzymes. Risk of Stomach Irritation The combination becomes especially irrit...

Watermelon + Dairy: Why This Refreshing Combo Can Upset Your Stomach Watermelon + Dairy: Why This Refreshing Combo Can Upset Your Stomach Watermelon is hydrating, sweet, and perfect on hot days. Dairy products like milk and yogurt are smooth and nutrient-rich. But when eaten together, this combination can cause digestive discomfort—especially for people with sensitive stomachs. High Water Content vs. Slow Digestion Watermelon is almost 90% water , which means it digests very quickly. Dairy, on the other hand, takes longer to break down. When these two are eaten together: • The stomach struggles with different digestion speeds • It may lead to bloating • Some people experience gas or mild cramping • Sensitive individuals may feel nausea The Cooling–Heating Conflict In traditional food science (especially Ayurveda), watermelon is considered a “cooling” fruit, while dairy is slightly “heating.” This opposite nature ca...

Pineapple + Dairy: Why This Combination Can Be Hard on Digestion Pineapple + Dairy: Why This Combination Can Be Hard on Digestion Pineapple is sweet, refreshing, and rich in enzymes. Dairy products like milk, yogurt, and cream are smooth and satisfying. But when combined, they can cause digestive discomfort for many people. The reason lies in the unique enzyme found in pineapple— bromelain . The Role of Bromelain Pineapple contains bromelain, an enzyme that breaks down protein. When bromelain reacts with dairy (a protein-rich food), it can cause: • Curdling in the stomach • Slower digestion • Bloating for sensitive individuals • A mild irritation in the digestive tract While not dangerous for most people, the combination is uncomfortable for many. Why the Combination Feels Heavy Pineapple is acidic. Dairy is neutral to slightly alkaline. When these two meet, the body needs extra time to process the mixture, leading to ...

Melon + Other Fruits: Why This Combination Can Upset Digestion Melon + Other Fruits: Why This Combination Can Upset Digestion Melons are refreshing, hydrating, and delicious—but they come with one special rule: “Eat melon alone or leave it alone.” This traditional nutrition principle exists for a reason. When melon is eaten together with other fruits like grapes or bananas, many people experience bloating, indigestion, or discomfort. Why Melon Doesn't Mix Well Melon digests very quickly—faster than most fruits. When you combine melon with slower-digesting fruits such as grapes or bananas , it tends to ferment in the stomach, leading to gas or bloating. The Digestion Speed Mismatch Melon : high water content, breaks down rapidly. Grapes & bananas : contain more fiber, sugar, and starch, which slows digestion. When these are eaten together, the melon may stay longer in the stomach than intended, causing discomfort for s...

Papaya + Lemon: A Surprising Combination You Should Know About Papaya + Lemon — A Fruit Pairing That Isn’t Always Gentle on Your Stomach Papaya is known as a digestion-friendly fruit thanks to the enzyme papain . Lemon is refreshing and acidic, rich in vitamin C. But when eaten together, this “healthy-looking combo” may actually cause discomfort for some people. Here’s what happens in your stomach — and how to enjoy both safely. Why Papaya + Lemon Can Be a Problem Papaya digests best in a low-acid environment because papain works optimally at mild pH levels. When you add lemon, its strong acidity can: reduce papain activity slow digestion instead of supporting it increase stomach acidity in people prone to reflux This mismatch may lead to mild heartburn, nausea, or a heavy stomach feeling. Who Should Be Cautious? Consider avoiding this combination if you: have acid reflux or gastritis easily get heartburn from acidic foods ea...
