Food- one of the most important ways to nourish your piggy! Guinea pigs need 75% timothy hay in their diet. Alfalfa is only to be used for pigs under six months of age. Very few guinea pig foods are timothy based. The only two I know of are Kaytee Timothy Complete and Oxbow Cavy Cuisine. I ONLY recommend Oxbow. Oxbow is a favorite among rescues and shelters, too. Oxbow, as pictured below, is LOVED by all my pigs! They squeal all day until they hear me scooping out their "yum yum's." Feed each of your piggies no more than 1/8 cup of Oxbow Cavy Cuisine once a day.
Vitamins- Because guinea pigs cannot manufacture their own Vitamin C it's extremely important they receive enough supplements of Vitamin C! Oxbow carries GTN-50C chewable tablets to be given to your piggies everyday (one per guinea pig).
Fruits/Vegetables- Your piggies MUST HAVE plenty of fruits and vegetables everyday! Do not feed any iceberg lettuce, nuts, or chocolate to your piggies. What to give them? Bananas, cucumbers, kale, oranges, apples, cantalope, and green leaf lettuce everyday.

Because I have so many Pigs to care for I use a feeding chart. I recommend making a feeding chart so you don't forget any vegetables! Here's some veggies I have on my chart: (in the Spring I use my garden to grow all my veggies, just be sure to have an organic garden with no pesticides)
Bell Peppers
Cucumbers
Celery and Carrots
Green Leaf Lettuce
Green Beans
Tomatoes (I use Better Boy tomatoes)
Parsley
Corn
Kale
Stay Away from Gas-forming vegetables such as broccoli and cauliflower.
Fruits to give your Piggy:
Pears
Apples
Cantalope
Oranges
Bananas
Blueberries
Berries (Blueberries, strawberries, blackberries in small amounts)
Don't give too much fruit! Fruits and vegetables also make good training treats, too. My Piggies are very picky so I have to rotate vegetables/fruit to keep them interested. Don't Forget! Your Piggy depends on you for life!*
