It looks like you might be referring to "tobacco" or "tacos," as "Talkis" isn't a widely recognized term. If you're talking about Takis, the spicy rolled corn snacks, it’s best to consume them in moderation. They are high in sodium, fat, and calories, which means eating them too frequently can contribute to health issues such as high blood pressure, weight gain, and other conditions.
Generally, enjoying Takis occasionally as a treat is fine, but try to balance them with healthier food options. If you meant something else by "Talkis," please provide more context!
