Is coffee good for you?


Is coffee good for you?

Most of us will have seen the research this week that store-bought coffees can contain a whopping 25 spoonfuls of sugar. Obviously that amount of sugar is not going to boost your but if you take the syrup out, is coffee good for you?

For those who missed the report, it was done by Action on Sugar, the pressure group trying to get the government to reduce the amount of sugar in our food.

It’s easy to say they have a vested interest in showing the drinks to have a lot of sugar, but it’s still obviously shocking to find that some coffee shop coffees have more sugar than three cans of Coke – and I’ve discussed the dangers of too much sugar in the past.

It wasn’t a week full of bad news for coffee drinkers though. Although it gained fewer headlines, another coffee-related report made the papers on Friday. It showed drinking two cups of coffee a day can help reduce the health risks associated with drinking too much alcohol (1)

It looked at nine previous studies with more than 430,000 participants and revealed that risk was reduced by 22 per cent with one cup of coffee and 43 per cent with two cups, compared to drinking no coffee at all.

Obviously drinking coffee to alleviate the symptoms of a bad lifestyle seems rather counterproductive, not going in for the alcohol abuse in the first place would seem a better option.

The benefits of moderate coffee consumption stretch further than helping those with alcohol-induced liver disease though. Coffee is now recognised as a good source of antioxidants (2,3) – the chemicals that can help slow down ageing and prevent certain diseases.

Recent studies have shown that it can help with conditions such as skin cancer, cataracts and bone health (4–6). One even suggests moderate consumption is not a risk factor for high blood pressure (7), while another showed it can be beneficial for those involved in resistance (weight) training (8).

If you’re rushing to the Nespresso machine as you read, you might want to hold on. Coffee remains a diuretic, meaning it makes you go to the toilet more affecting your hydration levels.

Another study has linked high levels of consumption with gastric cancer (9) while it can be a predictor of future cardiovascular events (read strokes and heart attacks) in younger people who are already suffering from high blood pressure (10).

It also stimulates the adrenal glands and is thought to increase the amount of cortisol (the stress hormone) in the body (11) which can link to increased agitation.
If you’re thinking by now that even the scientists can’t agree whether it is good for you or not, you’re probably right.

If you do drink coffee, follow these tips

  • Drink in moderation, no more than three cups per day,
  • Drink the best quality of coffee you can afford,
  • Avoid over-processed coffees such as instant where possible,
  • Drink the freshest ground coffee you can with beans from a sustainable, free-trade source,
  • Reduce sugar in coffee over time to none,
  • Don’t add sugary syrups, whipped creams etc to coffee shop coffee,
  • Increase your water consumption with coffee. In the Mediterranean, it is almost exclusively served with a glass of water on the side, you should follow suit,
  • Reduce your coffee intake if you suffer from high blood pressure.
