Welcome back to the latest edition of Longevity News! In this issue, we explore four compelling studies that bring new insights into health, wellness, and longevity. From nutrition during pregnancy to innovative diabetes treatments and the powerful mental health benefits of nature, these findings could be key in how we approach our daily health choices.
1. Fish During Pregnancy
A groundbreaking study has found that pregnant women who consume fish may reduce the risk of their child developing autism by 20%. This study highlights the importance of omega-3 fatty acids, which are abundant in fish, in brain development and overall neurological health. Autism spectrum disorder (ASD) affects millions of children worldwide, and this discovery could offer an easy dietary change that provides real benefits.
The key factor is omega-3, particularly docosahexaenoic acid (DHA), which plays a vital role in the development of the fetal brain. It has long been known that DHA and other omega-3 fatty acids contribute to cognitive function and neural growth. This new research goes further, suggesting a direct link between fish consumption and a lower risk of ASD. But while the benefits are evident, pregnant women are often advised to be cautious with fish consumption due to the risk of mercury exposure, which can negatively affect the baby’s development.
So, what’s the solution? Experts suggest focusing on low-mercury fish like salmon, sardines, and mackerel. These fish are packed with omega-3s and other nutrients essential for both mother and baby, without the risk of high mercury levels. Balancing fish intake during pregnancy could provide a natural boost to both prenatal health and long-term development in children.
2. Insulin-Metformin Combo
Managing type 2 diabetes has always been a complex task, especially when it comes to preventing complications like diabetic foot ulcers. However, a recent study highlights the potential benefits of combining insulin with metformin, offering a new approach for controlling blood sugar levels and reducing the risk of complications, including foot issues, which are a major concern for many diabetics.
Diabetic foot ulcers, a common and serious complication of poorly controlled diabetes, can lead to infections and even amputations if left untreated. The study found that patients using the insulin-metformin combination experienced fewer foot-related complications compared to those on insulin alone. This discovery is particularly significant, as foot ulcers contribute to a major portion of diabetes-related hospitalizations and healthcare costs.
Metformin, a widely-used oral diabetes medication, reduces glucose production in the liver, while insulin helps the body use glucose more effectively. Together, these treatments not only improved overall glycemic control but also had a protective effect on the vascular system. Diabetic foot ulcers are often linked to poor circulation and nerve damage, both of which are worsened by high blood sugar levels. The combination therapy’s ability to enhance insulin sensitivity and improve blood flow likely plays a role in lowering the risk of these foot-related issues.
- Nature’s Power
A cross-governmental project has recently demonstrated the powerful impact of expanding access to Green Social Prescribing, an innovative approach that uses nature-based activities to support mental health and well-being. Green Social Prescribing connects individuals, particularly those experiencing mental health challenges like anxiety, depression, or loneliness, to outdoor activities such as gardening, walking, and conservation efforts.
The study highlighted that increased access to nature through social prescribing can significantly enhance mental health outcomes. Participants in the program experienced reduced levels of anxiety, lower stress, and improved overall well-being. These effects are largely attributed to the calming properties of nature, which has been shown to lower cortisol levels and promote relaxation.
What makes Green Social Prescribing particularly valuable is its accessibility. It provides an alternative or complementary treatment to traditional mental health interventions such as medication or therapy. For many, it offers a non-medical pathway to recovery. Plus, the initiative promotes social interaction and physical activity, both of which are known to improve mental health.
Governments are increasingly recognizing the importance of integrating nature-based activities into public health strategies. The success of this project has inspired calls to expand Green Social Prescribing, ensuring that more people can access these mental health benefits. As urbanisation rises and green spaces become more limited, demonstrating that nature is not just a luxury, but an essential component of a healthy, balanced life is key.
- NMN to Prevent Cellular Breakdown
NMN has been studied for its ability to boost NAD+ levels, a crucial molecule that supports cellular energy, DNA repair, and overall vitality. As we age, our NAD+ levels decline, leading to reduced cellular function and an increase in age-related diseases.
However, a recent study has uncovered that NMN might help prevent a specific kind of cell death called lysosomal ferroptosis, linked to ageing and diseases like cancer and neurodegeneration.
So, what is ferroptosis? Unlike apoptosis (a process of programmed cell death that occurs naturally to remove damaged cells), ferroptosis is driven by the buildup of iron within cells, which leads to oxidative damage of cell membranes. This damages the structure of the cell and ultimately causes it to die. Ferroptosis has been increasingly linked to many chronic diseases, and it’s considered a contributor to the ageing process itself. The problem is that this kind of damage, once it starts, can spread like a wildfire, damaging cells that are crucial to our health and longevity.
The new study shows that NMN might help regulate this destructive process. NMN, by boosting NAD+ levels and promoting healthier lysosomal function, appears to help regulate iron within the cells, reducing the likelihood of ferroptosis taking place.
This means that NMN may do more than just boost your body’s energy levels and support DNA repair, it could actively protect your cells from the kind of damage that speeds up ageing. By preventing ferroptosis, NMN might be slowing down one of the cellular processes that contribute to diseases like Alzheimer's, Parkinson’s, and even certain cancers. And it’s this dual benefit of both boosting energy and preventing damage that makes NMN such a powerful contender in the quest for longer, healthier lives.
