Gia makes a point to always join her family for Sunday dinner, which usually consists of a lavish Italian spread cooked by mom Teresa. "I mean, my food is pretty fabulous. Pretty delicious," Teresa says. "Usually everybody that comes over is like, 'Oh, my God, this is so good.' You know? It's good to hear." "Family meals provide an opportunity to sit and be present with each other after busy days," says Wendy Jo Peterson, MS, RDN. "The mealtimes reinforce values, traditions and cultural connectivity. A report from CASAColumbia (CASA*) at Columbia University says that families who shared meals 5 to 7 times per week were less likely to use drugs, smoke or consume alcohol. Yes, positive family relationships and open communication around the table are that powerful!"

Gia loves big salads, especially with fish and avocado. "Avocados have been commended as an example of a nutrient-dense food, with one half of the fruit counting towards your five-a-day," says registered nutritionist Jo Lewin. "Avocados are an excellent source of monounsaturated fat and vitamin E, and are a good source of folate. They also supply more soluble fiber than other fruit and contain a number of useful minerals including iron, copper and potassium."

Gia enjoys eating seafood, especially conch fritters on the beach. "Typically, all shellfish is low in calories and a good source of protein and healthy fats, as well as a good array of nutrients, including zinc, B12, iron and selenium," says registered nutritionist Nicola Shubrook. "They are also more nutritious if they are steamed or baked rather than breaded or fried."

Gia loves pancakes, eggs, and potatoes for breakfast. "Much of the research just makes good common sense," says Christy C. Tangney, PhD. "If you start with a healthy, satisfying meal in the morning you're less apt to nibble on less nutritious things during the day, which we often do out of hunger — you grab the first or easiest thing in front of you."

Gia frequently incorporates sushi as part of her diet. "Sushi can contain a lot of the different food groups wrapped up in one," says Maxine Smith, RD, LD. "As in many cases, simplicity is best. A simple roll is very low in calories. It could be equal to a light meal, so you're talking about 300 calories or so. You can easily double that when you get into some of the fancier rolls and larger supreme rolls."
