Thanksgiving is the literal definition of the term "eucharist". However if you are referring to the sacrament, then "eucharist" may be called "The Blessed Sacrament", "The Lord's Supper", "Communion", "Holy Communion", "The Mass".
The Eucharist is also known as the Host, and it is representative of Jesus's body. During the Last Supper, Jesus broke bread and passed out wine to his disciples, highlighting their symbolism of his own flesh and blood, which he would sacrifice for their sins. Catholics receive the Eucharist, in the form of round bread wafers, during Sunday mass gatherings.
To my knowledge, there have yet to be made gluten-free Eucharists.
Holy Eucharist is the most common. There are numerous other ways to refer to it, such as Bread of Angels, Holy of Holies, etc. When referring to the physical object of the Eucharist after it ceases to be bread, the term "Host" is used.
In the earliest writing we have about the Eucharist (from the first century, probably around A.D. 60), the Eucharist is referred to as the "breaking of the bread and giving Thanks". from the Didache.
Eucharist and Sacrament
The Eucharist, also called Holy Communion or Lord's Supper and other names, is a Christian sacrament by which, in a common interpretation, those who celebrate it commemorate the Last Supper by consecrating bread and wine. There are different interpretations of the significance of the Eucharist, but "there is more of a consensus among Christians about the meaning of the Eucharist than would appear from the confessional debates over the sacramental presence, the effects of the Eucharist, and the proper auspices under which it may be celebrated."

Only Catholics celebrate the Eucharist. Catholics believe that Jesus is truly present under the appearances of bread and wine. Other christian denominations may have a 'communion service' in which they reenact the Last supper, but they believe that the Eucharist is a symbol of Jesus, not truly Jesus Himself. As a Lutheran clergyman who celebrates the Eucharist every week, I was surprised to read the above answer. While there may be many different names for the Eucharist ('Holy Communion', 'The Lord's Supper', and so on) they are only names and they do not necessarily indicate the understanding of the particular denomination. Lutheran theology teaches 'the Real Presence' of Christ's body and blood - 'in, with, and under the bread and the wine. Rather than "Consubstantiation" or "Transubstantiation", Lutherans believe in a "sacramental union" - that is we eat both the bread and the flesh, we drink both wine and the blood. Like Roman Catholics, Lutherans certainly do not teach that the Eucharist is nothing more than a symbolic meal, but rather that it is the real reception of the body and blood of our Lord.

Holy Communion (a communion service), and the Eucharist, are different names for the same thing. Holy Communion / the Eucharist was the ceremony instituted by Jesus at the Last Supper, as recorded in Mark 14:22-24: Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, "Take it; this is my body." Then he took the cup, gave thanks and offered it to them, and they all drank from it. "This is my blood of the covenant, which is poured out for many," he said.
