Kefir Plus Fiber Beat Omega-3 for Inflammation in New Trial

Can Fermented Foods and Fiber Really Fight Inflammation?

Yes. A six-week randomized trial found that combining fermented kefir with prebiotic fiber reduced more inflammation markers than omega-3 supplements or fiber alone. The synbiotic group, those taking both kefir and fiber together, showed the broadest and strongest drops in key proteins tied to chronic inflammation.

Chronic inflammation is a quiet driver of many serious health problems. It plays a role in heart disease, diabetes, and even certain cancers. Most people cannot feel it happening, but it shows up in blood tests as elevated proteins like IL-6 and TNF-alpha. Researchers at the University of Nottingham wanted to know which common dietary supplements do the best job of lowering these markers. They compared three options: omega-3 fatty acids, inulin fiber, and a synbiotic combination of fermented kefir with a diverse prebiotic fiber mix. The results suggest that the simplest kitchen staples may pack the most anti-inflammatory punch.

Ultra-Processed Foods Linked to 47% Higher Heart Disease Risk

Do Ultra-Processed Foods Raise Your Risk of Heart Disease?

Yes. A study of nearly 4,800 U.S. adults found that people who ate the most ultra-processed foods had a 47% higher risk of heart attack or stroke compared to those who ate the least. This held true even after researchers accounted for age, sex, race, smoking, and income.

Ultra-processed foods are everywhere in modern diets. Sodas, packaged snacks, frozen meals, and processed meats fall into this category. On average, participants in this study got 26% of their total daily calories from these foods. That is roughly one out of every four calories coming from items that have been heavily changed from their original form, often loaded with added sugar, salt, unhealthy fats, and artificial ingredients.

2-3 Cups of Coffee a Day Linked to 18% Lower Dementia Risk in 43-Year Study

Can Your Morning Coffee Actually Protect Your Brain?

Quite possibly. A landmark study published in JAMA followed 131,821 people for up to 43 years and found that those who drank 2 to 3 cups of caffeinated coffee per day had an 18% lower risk of developing dementia compared to people who drank little or none. Tea drinkers saw similar benefits at 1 to 2 cups daily. But here is the catch: decaffeinated coffee showed no protective effect at all, suggesting that caffeine itself may be doing something meaningful for the brain.

Hidden Gut Bacteria Linked to Better Health Worldwide

Could a Hidden Gut Bacterium Be the Key to Better Health?

Yes. A massive global study of over 11,000 gut microbiome samples from 39 countries found that a little-known group of bacteria called CAG-170 shows up consistently in healthy people, and at lower levels in people with chronic diseases like inflammatory bowel disease, obesity, and chronic fatigue syndrome. This is the first time a single bacterial group has emerged as a universal marker of gut health across so many different populations and conditions.

How Diet Controls Your Serotonin: The Complete Nutritional Guide

Which Nutrients Have the Biggest Impact on Your Serotonin Levels?

The most critical nutritional factors for serotonin production are the tryptophan-to-large neutral amino acid ratio (controlled by protein and carbohydrate balance), essential cofactor vitamins (B6, folate, vitamin D), minerals (iron, magnesium), and gut microbiota composition shaped by dietary fiber and probiotics. These nutrients work together to optimize both serotonin synthesis and the metabolic pathways that determine how effectively your body uses this crucial neurotransmitter.

Protein Before Sleep Increases Overnight Muscle Protein Synthesis in Older Men

Does Eating Protein Before Bed Actually Build Muscle Overnight?

Consuming 40 grams of casein protein before bedtime significantly increases overnight muscle protein synthesis rates in healthy older men, this randomized controlled trial demonstrates. The study found that pre-sleep protein ingestion elevated muscle protein synthesis by 22% during overnight sleep compared to placebo, with the effect sustained throughout the 7.5-hour sleep period. The protein was effectively digested and absorbed during sleep, with amino acid levels remaining elevated throughout the night. This research challenges the traditional view that muscle building only occurs during waking hours and suggests that the overnight period represents an important opportunity for muscle protein synthesis, particularly in older adults who may have reduced anabolic sensitivity.

US Caffeine Consumption: Coffee, Tea & Energy Drink Intake Statistics

Dr. Kumar’s Take

National dietary data show that caffeine consumption in the U.S. is stable over time, with coffee as the dominant source. These data provide context for interpreting population-level caffeine exposure and related health outcomes.

Key Takeaways

• Coffee contributes about 65–70% of total caffeine intake.
• Tea accounts for ~15%, sodas for ~10%, and energy drinks <5%.
• Average adult intake is around 150–300 mg/day, below EFSA safety thresholds.
• Intakes are higher in adults than adolescents and lowest in children.

Actionable Tip

Most adults consume caffeine well within safety limits. Energy drinks contribute a small but concentrated portion and should be monitored for total dose.

Can Eating Cherries Really Prevent Gout Attacks?

Dr. Kumar’s Take

This study gives solid evidence to something many patients have suspected for years: cherries can help lower the risk of painful gout flares. Both fresh cherries and cherry extract were linked to fewer attacks, with the best protection seen when patients also took allopurinol. While cherries are not a replacement for medication, they can be a simple and natural addition to a gout-friendly lifestyle.

Key Takeaways

✔ Cherry intake was linked to a 35% lower risk of gout attacks.
✔ Cherry extract showed similar protection, reducing risk by 45%.
✔ Combining cherries with allopurinol cut gout attack risk by 75%.
✔ Benefits appeared at about 2–3 servings in a 2-day period.
✔ Effects were consistent across men, women, obese and non-obese groups.

Coffee and Uric Acid: How Your Morning Cup Impacts Gout Risk

Dr. Kumar’s Take

This study shows that coffee drinkers may have lower uric acid levels and reduced risk of hyperuricemia, a condition that often leads to gout. Interestingly, it was not caffeine but other compounds in coffee, like antioxidants such as chlorogenic acid, that seemed to drive the benefit. Tea and overall caffeine intake had no effect. For patients at risk of gout, adding coffee to the diet could be a safe, simple lifestyle change.

Vitamin C in Human Health: Getting the Balance Just Right

Dr. Kumar’s Take:

This comprehensive review highlights that vitamin C is essential for human health because we cannot make it ourselves. The best approach is to get vitamin C from a balanced diet and thoughful supplementation during times of stress. People who eat plenty of fruits and vegetables will get enough vitamin C from food, but certain groups—like smokers or those with poor diets—should pay extra attention to their intake.

How All Forms of Vitamin K Become MK-4 in Your Body

Dr. Kumar’s Take:

This study from The Journal of Nutrition helps explain a big mystery in nutrition: why MK-4 is the dominant form of vitamin K found in our tissues, even though we eat mostly vitamin K1 (from greens) and other K2s (from fermented foods). Researchers fed mice different types of vitamin K and tracked how their bodies used it. No matter what kind of K they ate—K1, MK-4, MK-7, or MK-9—their tissues mostly converted it to MK-4. That means MK-4 might be the key “active” form used by our organs, and your body knows how to make it—if it gets enough of the raw materials.

Vitamin K2 May Help Protect Against Heart Disease, Study Finds

Dr. Kumar’s Take:

This large study from the Netherlands found that people who ate more vitamin K2 (menaquinone)—mostly from fermented foods like cheese—had fewer heart attacks, lower risk of dying from heart disease, and less calcium buildup in their arteries. Interestingly, vitamin K1, which comes from leafy greens, didn’t show the same benefits. This tells us that vitamin K2 may play a special role in keeping our blood vessels healthy and flexible.
