We believe in hygiene just like everyone else.
(Only on Shabbat are there certain restrictions. Though standing under running water on Shabbat is not prohibited, taking a shower is usually seen as impractical on Shabbat because some other things such as heating the water or drying one's hair with a towel are prohibited. As a result, most religious Jews take a shower right before Shabbat begins so that they are clean and presentable on Shabbat. During the rest of the week, most religious Jews take daily showers as is appropriate.)
Religiously observant Jews say a blessing for the food they're about to eat, before every meal and snack.
For example, if the food being eaten is a salad, a blessing to God is said for food from the ground. If the meal includes a drink such as water, a different blessing is said. These blessings are short, one sentence long. There are much longer blessings recited after a meal is eaten.
Rules for eating around the daily prayers
Religiously observant Jews say their morning prayer before eating anything each morning. The reason is that one should fulfill one's spiritual needs and obligations towards God before one's physical needs. If because of weakness it is difficult for one to concentrate on the prayers without having some food beforehand, it is permissible to have some food beforehand.
Similar practices are kept at other times as well. For instance, Jews will say Friday night prayers before eating the Friday night supper in honor of the Shabbat.
Some Hasidic Jews bathe in a mikvah, a ritual bath, before the morning prayers. However, it is not Halakhically required.

All God religions; including Judaism, Christianity, and Islam; call their followers to be thankful to God (Allah) and to request His blessings and forgiveness. This call includes praying for God before eating and after eating. Muslims used also before eating or drinking to say "In the name of Allah the All-Merciful the All-Glorious" and pray Him to forgive them and bless them. After drinking or eating, they say " Thank to God " and they pray him to bless them with good health.
Christians and Jews believe that there is one true God. Christians and Jews pray to the same God.
Jews pray facing the east-in the direction of Jerusalem
Normally, we pray in Hebrew. But if one reads the blessings in English, that word ("blessed") would be found. For example, "Blessed are you, Lord our God, King of the universe, who brings forth bread from the earth" (before eating bread).
