It's time to crawl up on the couch and embrace the autumn darkness.

For many, autumn also means a fresh start in terms of diet and health.

One of the biggest dietary trends ahead of the autumn is drinkable vinegar, which is said to help keep blood sugar down and improve the feeling of satiety.

Those who want to catch up with the trend can, for example, start with apple cider vinegar.

But as always with dietary trends, there are two sides to the coin.

Professor critical of drinking vinegar

Mai-Lis Hellénius is a professor and chief physician at Karolinska Institutet and researches lifestyle issues and diet.

She is skeptical about drinking vinegar.   

- No, you should not drink so much vinegar.

It lowers the glycemic index in the body, which means that you get a slightly lower blood sugar rise.

So what you can say is that it is good to have vinegar on the salad, but to drink it is not recommended.

Phenomenon on Instagram - smurflatten

Another trend that has become big in several countries, after inspiration from a vegan café in Australia, is the vegan super drink called smurflatte.

It is a blue latte made from blue algae powder and spirulina, among other things.

Smurflatten has become a phenomenon on Instagram and is said to be a real vitamin bomb that strengthens the immune system. 

- In most trends like this that come, there is something good and wise.

But what I advocate in front of quick and easy solutions is that you look at your whole lifestyle.

The risk is that it will be 'now I do something healthy', but nothing is done about the real problems, says Mai-Lis Hellénius.

More and more people are becoming flexitarians

Two other trends that are coming strong, according to nutrition and exercise expert Martin Kreutzer, employed at the University of Copenhagen, are the interest in fat and the interest in becoming a so-called flexitarian.

- The trend to eat less meat is growing more and more.

This means that there are many new products on the market, vegetarian alternatives with protein.

But it is a cultural development that takes time.

Even though more and more people are choosing that path, it is a trend that we have only seen the start of, he says.
