• A diet revolving around meat and dairy will take a greater toll on global resources than a diet revolving around unrefined grains, nuts, fruits, and vegetables, which is a significant concern given the global population is expected to reach nine billion by 2050.
• The 'paleo diet' recommends consuming meat, fish, fruits, vegetables, eggs, and nuts, while excluding cereal grains, dairy products, legumes, refined sugar, and processed foods.
• The Mediterranean-Style Dietary Pattern Score (MSDPS) assigns points based on daily or weekly servings of specific food groups, including whole grains (8 servings/day), fruits (3 servings/day), vegetables (6 servings/day), dairy (2 servings/day), wine (1.5 servings/day for women, 3 servings/day for men), fish/seafood (6 servings/week), poultry (4 servings/week), olives/legumes/nuts (4 servings/week), potatoes/starchy roots (3 servings/week), eggs (3 servings/week), sweets (3 servings/week), and meat (1 serving/week).
• The Mediterranean Diet Score (MDS) ranges from 0 (minimal adherence) to 9 (maximal adherence) and is calculated based on nine components: vegetables, legumes, fruits and nuts, cereal, fish, the ratio of monounsaturated to saturated lipids, meat, dairy products, and alcohol.
