While underlying mechanisms remain elusive, immune factors and lifestyle components, such as diet and physical activity, could play a role in shaping disea...

Food security is an immensely complex issue connected to global food production and supply systems. One of the key challenges is to provide sufficient, safe, and nutritionally balanced food for everyone on the planet. It is closely linked to many factors including population growth, poverty, economic stability, and environmental sustainability. Cur...

Cardiovascular disease (CVD) is a leading cause of death in women and risk of development is greatly increased following menopause. Menopause occurs over several years and is associated with hormonal changes, including a reduction in estradiol and an increase in follicle-stimulating hormone. This hormonal shift may result in an increased risk of de...

Rooibos tea, traditionally consumed by Indigenous populations, is naturally caffeine-free and contains unique polyphenols with strong antioxidant, anti-inflammatory and anti-hyperglycaemic properties.
