Secret of a longer, fertile life
AN AMINO acid in fish, meat and wheat may hold the key to living a long, healthy life, say scientists.
They found that balancing the intake of the amino acid methionine in fruit flies can extend lifespan without reducing fertility. Methionine is one of the building blocks of the proteins that make up all cells and tissues.
Studies in animals ranging from flies to monkeys have shown that reducing food intake can benefit health and increase lifespan. However, calorie restriction also tends to reduce fertility.
The research, from the Institute of Healthy Ageing at University College London, is published in the journal Nature.
