A new study from Harvard T.H. Chan School of Public Health reveals that what you eat in your 40s and 50s can greatly impact how you age.
Researchers followed over 105,000 adults for three decades and found that those who followed plant-rich diets—like the Mediterranean, DASH, or AHEI—had up to an 86% higher chance of reaching age 70 in good physical, cognitive, and mental health. Key components of these diets included plenty of fruits, vegetables, whole grains, nuts, and legumes, along with minimal ultra-processed foods like sugary drinks and processed meats.

Your brain is mostly fat, and it runs best on quality fuel. Bulletproof Brain Octane Oil is apure C8 MCT oil derived from coconut oil that converts quickly into ketones—an efficient energy source for your brain. Adding it to your daily routine can support clearer thinking, better focus, and steady energy without the jitters or crash of caffeine.
A recent study published in Clinical Psychological Science suggests that strong verbal fluency—the ability to quickly and effectively use language—may be linked to longer life spans. Researchers analyzed data from the Berlin Aging Study, which followed 516 individuals aged 70 to 105 over nearly two decades. Among various cognitive skills tested, verbal fluency stood out as a significant predictor of longevity.
The study involved tasks like naming as many animals as possible within 90 seconds to assess verbal fluency. While the exact reason for the connection remains unclear, one theory is that verbal fluency reflects overall brain health, integrating memory, vocabulary, and processing speed. This research highlights the potential importance of maintaining language skills as we age.

A new review published in Frontiers in Nutrition draws a clear line between vitamin deficiencies and depression risk in later life. Researchers found that low levels of key nutrients—especially B12, vitamin D, folate, and B6—may disrupt brain functions that regulate mood. These deficiencies appear to interfere with neurotransmitter production, increase inflammation, and add oxidative stress to the brain, all of which can contribute to the onset of depression in older adults.
For those who prioritize long-term mental well-being, the message is clear: keeping an eye on micronutrient intake could be just as vital as regular exercise or sleep.

A new study published in European Journal of Pharmacology suggests that the connection between your gut bacteria and mitochondria—the tiny engines inside your cells—could play a key role in cardiovascular health. Scientists are discovering that these two systems don’t work in isolation. Instead, they appear to “talk” to each other, and when that communication breaks down, it may contribute to heart disease.
What makes this research particularly interesting is how diet and lifestyle could influence this gut–mitochondria relationship. Since both gut bacteria and mitochondria are sensitive to what we eat and how we live, future treatments might focus on improving heart health by supporting this internal network.

We're living in an age where wellness is no longer about fads—it's about precision. Australians aren't just popping pills anymore; we're demanding clean, proven compounds that actually shift the dial. Discover why sulforaphane is becoming Australia’s go-to supplement for inflammation, detox, energy, and cognitive clarity.
The idea of improving one’s microbiome to slow ageing has gained attention. Dr. Kara Fitzgerald, a functional medicine physician and epigenetics researcher, has laudedUrolithin A as a “postbiotic rockstar” in the longevity space. She notes that Urolithin A(UA) has studies published in top-tier journals such as Nature and Cell – with 11 compelling human clinical trials and calls it a nutrient that should be on the radar for mitochondrial health.
Recent 2025 research confirms sulforaphane’s broad therapeutic potential across cancer prevention, neuroprotection, metabolic health, and inflammation—driven largely by its activation of Nrf2 and modulation of cellular stress responses. Human and animal studies increasingly support its use as a safe, multi-target compound with applications in chronic disease prevention, aging, and adjunctive treatment strategies.
