Sikhs have their own laws and code of conduct. In those laws it states that they cannot eat "Kuttha" meat, ie.e that which has been ritually killed (halal or Kosher).
In the Rehit Marayada (http://www.sgpc.net/rehat_maryada/section_six.html), Section Six, it states:
The undermentioned four transgressions (tabooed practices) must be avoided
1. Dishonouring the hair;
2. Eating the meat of an animal slaughtered the Muslim way(Kutha);
3. Cohabiting with a person other than one's spouse
4. Using tobacco.

Sikhs do not believe in ritual killing and are told to refrain from eating meat killed by such rites as halal and kosher. Most Sikhs are vegetarian
Sikhs that are "full Sikh's" (Baptist Sikh) can not eat any kind of meat nor eggs. Sikhs that are normal can eat meat and eggs but they can not eat halal nor beef.
No Sikhs are not vegetarian although many choose to be. One a Sikh has taken the Amrit ceremony (a form of Sikh baptism) they are not allowed to eat Kutha meat (meat which is ritually prepared like Halal or Kosher).
Sikhs can eat rice and wheat products. They also eat milk products but some Sikhs do not eat meat
In Sikhism food that is good for your mind and body is acceptable. This includes vegetables, meat and fish. Sikhs however, cannot eat ritually sanctified meat (i.e. Kuttha = Halal, Kosher etc). Many Sikhs out of respect for their Hindu neighbours do not eat beef, because the Hindu deems the cow to be sacred.
Yes it is halal.
Islam is a religion so a religion cant eat but i think you mean Muslims. Muslims can eat anything that is halal like chicken pizza chips cake ect
yes Muslim can eat hotdogs only if they are halal. There are all kinds of hotdogs chicken, beef and pig but muslims cant eat pig.
To drink (control) anger is halal but to eat it is haram.
their is noting that can be harame when you eat it if it is halal when you drink it or if it is haram to eat it it is haram to drink it to
Sikhs eat sweets on Diwali. the sweets include laddoos, barfi etc.
Muslims do not eat halal for scientific reasons; they do it because God commanded that they eat this way.
