Safety and Clinical Viability
Maintaining pH stability and avoiding tissue overheating are critical for the clinical application of direct current. The Lab on a Chip research ensured safety by keeping the current in the microamp to milliamp range and using high-capacity charge-storing electrodes. This helped prevent Joule heating and harmful pH shifts—protecting surrounding tissue and allowing the body’s natural repair systems to function without interference.
Conclusion
Advancements in microfluidic technology and biocompatible conductive materials have enabled the safe use of electricity to accelerate wound healing in cellular models. The study clearly demonstrated that a direct electric field of about 200 mV/mm significantly enhances keratinocyte migration—reducing wound closure time by up to 3 times.
This effect holds even in models simulating impaired healing, such as diabetic wounds. The use of non-metallic electrodes and precisely calibrated current doses supports the feasibility, effectiveness, and safety of electrostimulation as a powerful new tool in regenerative medicine.
Harvard Reveals the Optimal Diet for Healthy Aging, Backed by 30 Years of Scientific Research
Healthy aging has become one of the main public health goals around the world. More and more people are seeking evidence-based strategies not only to increase lifespan but also to maintain physical and mental quality of life as they age. In this context, Harvard University conducted a comprehensive study over 30 years to identify dietary guidelines that can promote healthy aging.
According to research published in the journal Nature Medicine, the findings reveal that a balanced diet rich in plant-based foods and low in unhealthy fats and added sugars is a key factor in aging well. This article provides an overview of the study’s main findings.
The Importance of Nutrition in Healthy Aging
As life expectancy increases globally, new health challenges emerge. Experts emphasize that longevity alone is not enough; the goal should be to reach old age with a lower risk of chronic diseases, high energy levels, and strong physical function. The Harvard study evaluated the diets of thousands of participants over three decades, analyzing variables such as fat intake, protein sources, fruits, vegetables, whole grains, and sugary drinks.
The results showed that a diet high in fruits, vegetables, whole grains, nuts, and legumes significantly reduces the risk of chronic illnesses. Additionally, moderate intake of healthy fats—such as olive oil or avocado—provided extra benefits for heart and brain health. Conversely, a high intake of processed meats, sugary beverages, and ultra-processed foods was associated with an increased risk of metabolic disorders.
Essential Components of the Optimal Diet According to Harvard
Harvard’s optimal diet for healthy aging is based on variety and balance. Key components include:
✅ Plenty of fruits and vegetables: High intake is linked to better cognitive function, reduced inflammation, and lower cardiovascular disease risk. Leafy greens (spinach, kale, chard) and yellow/orange vegetables (carrots, pumpkin) are especially important.
✅ Whole grains: Examples include oats, whole wheat bread, brown rice, and quinoa. They help regulate blood sugar and maintain healthy cholesterol levels.
✅ Healthy plant and animal proteins: Legumes (lentils, chickpeas, peas) and nuts provide valuable protein and support heart health. Fatty fish like salmon—rich in omega-3s—should be eaten at least twice a week. Choose lean meats like chicken and turkey, while limiting processed meats.
✅ Healthy fats: Olive oil and nuts (walnuts, almonds) provide unsaturated fats that protect the heart. Limit butter and margarine containing trans fats.
✅ Low-fat dairy: Opt for skim or partially skim milk and plain yogurt without artificial sweeteners.
✅ Hydration: Prioritize water and unsweetened teas. Limit coffee, sugary drinks, and energy beverages.
