1. She Enjoys Plant-Based Milks

Galvin loves to take her coffee with plant-based options such as coconut, oat, or almond milk. “There’s really no downside to drinking plant-based milk instead of cow’s milk,” says Dana Ellis Hunnes, PhD, MPH, UCLA Health senior dietitian. “Although milk is only one small part of a person’s diet, plant-based milk along with a plant-forward diet offers many benefits for your health and the environment.”

2. She Follows a Vegan Diet

Galvin sticks to vegan foods, a diet experts say has many health benefits. “Plants give your body what it needs to help fight off infection,” says Andrea Murray, MD Anderson health education specialist. “A plant-based diet strengthens your immune system to protect you against germs and microorganisms. Antioxidants in plants grab all these so-called free radicals that can throw your body off balance. To reduce inflammation, it’s important to eat plant-based and to listen to your body’s signals for how foods work for you.”

3. She Loves Fruit

Galvin enjoys snacking on fruit, especially strawberries and raspberries. “Strawberries are rich in colorful pigments which have a protective effect – these anthocyanidins are thought to have a number of potential health benefits, including prevention of inflammatory conditions and heart disease,” says registered nutritionist Jo Lewin. “Observational studies appear to link regular berry consumption with fewer heart-related deaths.”

4. She Enjoys Cycling

Galvin loves to cycle, especially at the beach. “Exercise, and physical activity more generally, can prevent or help manage a number of chronic conditions, and participating in regular activity can also strengthen bones, improve cognitive function and help people lose weight,” says Jennifer Gay, an associate professor in the University of Georgia’s College of Public Health. “Being active outdoors can be good for our health in different ways. Spending time in green or blue spaces like parks, forests or lakes contribute to improved mental well-being.”

5. She Takes Her Vitamins

Galvin likes to supplement her diet with vitamins. “Vitamins play background roles in our bodies,” says registered dietitian Kate Patton, MEd, RD, CCSD, LD. “We need vitamins to break down macronutrients like carbohydrates, fat and protein and help the body function. People might take supplements if they know they’re missing a certain food group. Others might take supplements for the antioxidant benefits or because they know they don’t eat fruits and vegetables. Some people may have a true deficiency.”
