Review Warns of Antioxidants

A new review published in the British Journal of Pharmacology reinforces an emerging explanation for why vitamins E and C, along with other antioxidant supplements, don’t prevent disease and may sometimes even cause harm. Oxygen free radicals – the molecules that antioxidants neutralise – aren’t all bad. Although they can trigger disease, they’re also essential to immune defence and hormone synthesis. The amount of antioxidants found in a balanced diet appears beneficial, but getting a surplus from a supplement risks interfering with helpful free radicals.

The Upside of a Little Butter

A meta-analysis of nine studies involving a total of more than 600,000 subjects in 15 countries found that a modest daily amount of butter – one tablespoon (14g) – was associated with a four per cent decrease in diabetes risk. Meanwhile, this same amount of butter didn’t seem to increase the risk of cardiovascular disease or stroke. Moderation is a good strategy when it comes to high-fat foods such as butter, and the review implied that there’s no need to avoid them altogether.

Health Affected by Work

Having a job suited to our personality and skills is nice, but it’s not only what we do at work that affects our wellbeing. It’s also how we relate to the people there. An analysis of 58 studies in 15 countries found that people who experience a strong sense of belonging at the workplace tend to have better overall health and a lower risk of burnout. We derive purpose and meaning from membership in groups, and the benefit is more pronounced when our colleagues also identify with the organisation or team.
