Home cooking may not be as healthy as you think. The longer people spend preparing meals, the worse their health becomes, a study found. And it shows that food isn’t healthy just because it is cooked at home. 

Possible reasons are home cooks being generous with unhealthy ingredients such as butter and salt and feeling they have to eat more because of the time and work that they have spent. 

It is also possible, say the researchers, that convenience foods have become healthier. 

The researchers, from Rush University in Chicago, studied more than 2,755 women in their 40s, 50s and 60s for 14years. It is about how long they spent cooking and the results of annual health checks for something called metabolic syndrome. Metabolic syndrome will raise the possibility of heart disease and strokes. 

The women who spent the longest cooking and clearing up meals were more likely to develop metabolic syndrome. Similarly, if a woman started to spend more time cooking, her possibility of metabolic syndrome rose more quickly than average. However, women who did less cooking as time went on cut their possibilities of health problems. 

Researcher Dr Brad Appelhans said that it is important to cook healthily, not just often.
