Keto and Bolero drinks?

[WNationalist]

Bolero drinks are highly popular as they claim to have 0 calories, but given their content:

ACIDS: CITRIC ACID, MALIC ACID

BULKING AGENT: MALTODEXTRINE

NATURAL FLAVOURINGS; SWEETENERS: ACESULFAME K, SUCRALOSE, STEVIOL GLYCOSIDES (STEVIA EXTRACTS)

ACIDITY REGULATOR: TRISODIUM CITRATE

ANTI-CAKING AGENT: TRICALCIUM PHOSPHATE; THICKENERS: GUAR GUM, GUM ARABIC (ACACIA GUM); L-ASCORBIC ACID (VITAMIN C)

COLOUR: COLOURING CONCENTRATE FROM CARROT.

It still says that the carb content is zero per packet, but it does contain maltodextrine...are the drinks safe for a keto-diet?

It seems that cereals is the most commonly listed food in breakfast, but do you know what ingredients are used in cereals? You may have read the ingredients label and noticed some ingredients that do not look like they belong in the cereal we eat, and one of them is the trisodium phosphate.
