The common understanding of what is good for our bodies is becoming more sophisticated, with new longitudinal research and meta-reviews bringing us closer to the truth.
In one of the largest ever sleep studies, which was initiated in 2017, participants who reported sleeping the doctor-recommended seven to eight hours outperformed those who slept more or less. Lack of sleep can also influence testosterone production in young men, according to a review of studies published in 2010. Here are some commonly held ideas, as well as what research says now, so you may make informed health decisions this year.

2. ‘Breakfast is the most important meal of the day’
3. ‘You should walk 10,000 steps a day’
