Twelve months in a year, vitamin B12

The quantity of Vitamin B12 required for a healthy diet is measured in micrograms, but the impact on human health is far greater than these tiny amounts would suggest.

Understanding the basics of nutrition

The importance of proper nutrition is often underestimated. The nutrients in food provide energy, contribute to tissue growth and repair, and regulate physiological processes. Nutritional needs vary depending on age and physical condition.

Remember to rest

Sunday afternoons were a sacrosanct time when I was growing up in Argentina. Everything seemed to quiet and slow down between 2:00 and 5:00 pm, during siesta. Even shops would shut. All you could hear was the sound of the cicadas as the whole neighbourhood took a nap. Young and old, rich and poor were unified by this wonderful tradition. At least, I...

The war with Bacchus

On 17 January 1920, America officially "dried up". It wasn't a shortage of water or a prolonged drought, but a law banning the sale, transport, and commercial production of alcohol.

Genetic inheritance cannot be altered. True or false?

Grandpa’s eyes, mother’s wide hips, aunt’s serene gaze, father’s ambition, great-grandmother’s rheumatism—all the little traits that define us seem to come from ancestral parents who, together, should have all the genes that anyone can have today, all the possible ingredients for the recipe from which we were made.

Hope in the storm

This coronavirus crisis has, for me, some perplexing parallels with a well-known incident narrated in the Gospel of Matthew (14:22-33). The disciples are confined in a little boat in the middle of a terrible storm, almost as we are confined at home today by the emergency laws of our countries.

One habit healthier. What we need to know about change

Understanding breast cancer

COVID-19: When time no longer means money
