What is the NU-AGE Food Plan?The NU-AGE food plan follows the Mediterranean-style of eating which builds meals around vegetables, fruit, whole grains and legumes; limits saturated fat, trans fats, sodium and added sugars; and includes more fish and lean sources of protein. In this study, the NU-AGE plan included:

• 4-6 servings of whole grain bread, pasta or rice each day
• 2 servings of fruit each day, with fresh fruit given a higher preference over canned fruit or fruit juice
• 2 cups of vegetables each day, either cooked or raw
• 2 cups of cooked legumes (dried beans and peas such as lentils, black beans, pinto beans, and kidney beans) per week
• 2 cups of non-fat or low-fat milk or yogurt per day
• 1 ounce low-fat cheese per day
• fish twice per week
• low-fat meat or poultry four times per week
• ¼ ounce of nuts per day
• 2-4 eggs per week
• 1 tablespoon olive oil per day
• 50 ounces, or about 6.3 cups, of water each day

In addition, the NU-AGE eating plan includes a daily vitamin D supplement, limits any type of alcohol to no more than 2 drinks per day for men and no more than 1 drink per day for women, limits sodium to a maximum of 2000mg per day, and limits sweets.Let’s Make Healthful Choices:Current health guidelines encourage eating more vegetables, fruit, whole grains, legumes and choosing lean sources of protein while limiting sodium and added sugar.In the study published in Gut, the NU-AGE diet led to changes in the microbiome that increased the type of bacteria that produce beneficial short chain fatty acids and decreased the type of bacteria that produce bile acids that are linked to increased risk of chronic disease.This study shows that making changes in our food choices is important as we get older, and can have a positive, healthy, beneficial impact on our physical health and cognitive capabilities.By Lynn Grieger, RDN, CDE, CPT, CHWC References
