I have bolded the part at the start and again at the finish. These are the two areas that would answer your question.
The general welfare clause right at the start of Section 8 is broad giving Congress the power to provide for the general welfare of citizens of the USA. The term general welfare is not defined within the document and is rather broad but its scope is up to the interpretation of the Supreme Court in the end. At the end of Article 8 is the clause called The Necessary and Proper Clause or sometimes The Elastic Clause. This gives Congress the power to carry out all the powers given to it in the previous clauses. When you combine those two together you get rather wide powers that Congress has to do many things. Health care would come under that.

So I'm curious what others would say to those who argue that government healthcare can't be allowed because the constitution doesn't say it's allowed?
You may have noticed that the debate surrounding the Health Care bill pretty much centers around the practical questions regarding it... the cost, how to pay for it, its impact on the quality of care, the role of the government in health care, private sector versus public, a public option, keeping costs down and other such issues. We have not really seen any serious mainstream Constitutional objections to such a program... yet. Although should such a law pass, it could be challenged in the courts and eventually the Supreme Court could indeed examine if it is Constitutional.
