If i go to mexico, will having lots of spices or tequila help prevent food poisoning?

Negative!: Drink bottled water (or tequila). Eat well cooked foods from reliable places. Don't drink tap water. Avoid street vendors. Eat vegetable and fruits that you can peel (like bananas or oranges). That said, bring some pepto bismal. See:http://www.Medicinenet.Com/travelers_diarrhea/article.Htm consider taking some Cipro (ciprofloxacin) with you.
