Love them or hate them Brussels sprouts are a very healthy low carb vegetable. It is a cruciferous vegetable and as such is good for your liver.

As well as containing fiber, Vitamins C, K and E, folate, beta-carotene, they contain glucosinolates, a phytochemical. They get broken down by cooking and digestion to isothiocyanates which are thought to have anti-cancer properties.

Balsamic Vinegar

If you’ve never used balsamic vinegar before it is a dark, slightly sweet vinegar used for salad dressings, sauces and marinades.

Traditional balsamic vinegar is made from juice of freshly pressed sweet Italian grapes.  They will always be labelled Aceto Balsamico Tradizionale.

The grape juice known as “must” is boiled to make a concentrate then fermented and acidified. After this it’s aged for 12 to 25 years or longer in wood barrels. This is why it is so expensive.

Modern commercial balsamic vinegars which you will find in supermarkets or grocery stores combine concentrated grape must with wine vinegar to speed up the acidification process. This vinegar is typically aged from 2 months to 3 years in large oak barrels.

Most balsamic vinegars are keto-friendly but check the label to make sure there is no  added sugar. Some are higher in carbs than others. Make sure also there are no additives.

Spelling – Brussels with an “S”or without? 

I’ve spelt Brussels with an “S” on the end in the heading above. You may have noticed that in the title there is no “S” on the end of Brussel. There is some debate about which is the correct spelling but they are named after Brussels, a city in Belgium. It has an “S” on the end so that is the correct spelling.
