What is halal food?

حُرِّمَتۡ عَلَيۡكُمُ ٱلۡمَيۡتَةُ وَٱلدَّمُ وَلَحۡمُ ٱلۡخِنزِيرِ وَمَآ أُهِلَّ لِغَيۡرِ ٱللَّهِ بِهِۦ وَٱلۡمُنۡخَنِقَةُ وَٱلۡمَوۡقُوذَةُ وَٱلۡمُتَرَدِّيَةُ وَٱلنَّطِيحَةُ وَمَآ أَكَلَ ٱلسَّبُعُ إِلَّا مَا ذَكَّيۡتُمۡ وَمَا ذُبِحَ عَلَى ٱلنُّصُبِ وَأَن تَسۡتَقۡسِمُواْ بِٱلۡأَزۡلَٰمِۚ ذَٰلِكُمۡ فِسۡقٌۗ ٱلۡيَوۡمَ يَئِسَ ٱلَّذِينَ كَفَرُواْ مِن دِينِكُمۡ فَلَا تَخۡشَوۡهُمۡ وَٱخۡشَوۡنِۚ ٱلۡيَوۡمَ أَكۡمَلۡتُ لَكُمۡ دِينَكُمۡ وَأَتۡمَمۡتُ عَلَيۡكُمۡ نِعۡمَتِي وَرَضِيتُ لَكُمُ ٱلۡإِسۡلَٰمَ دِينٗاۚ فَمَنِ ٱضۡطُرَّ فِي مَخۡمَصَةٍ غَيۡرَ مُتَجَانِفٖ لِّإِثۡمٖ فَإِنَّ ٱللَّهَ غَفُورٞ رَّحِيمٞ

Prohibited to you are dead animals,[241] blood, the flesh of swine, and that which has been dedicated to other than Allāh, and [those animals] killed by strangling or by a violent blow or by a head-long fall or by the goring of horns, and those from which a wild animal has eaten, except what you [are able to] slaughter [before its death], and those which are sacrificed on stone altars,[242] and [prohibited is] that you seek decision through divining arrows. That is grave disobedience. This day those who disbelieve have despaired of [defeating] your religion; so fear them not, but fear Me. This day I have perfected for you your religion and completed My favor upon you and have approved for you Islām as religion. But whoever is forced by severe hunger with no inclination to sin - then indeed, Allāh is Forgiving and Merciful.

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِنَّمَا ٱلۡخَمۡرُ وَٱلۡمَيۡسِرُ وَٱلۡأَنصَابُ وَٱلۡأَزۡلَٰمُ رِجۡسٞ مِّنۡ عَمَلِ ٱلشَّيۡطَٰنِ فَٱجۡتَنِبُوهُ لَعَلَّكُمۡ تُفۡلِحُونَ

O you who have believed, indeed, intoxicants, gambling, [sacrificing on] stone alters [to other than Allāh], and divining arrows are but defilement from the work of Satan, so avoid[282] it that you may be successful.
