Plant-based diets (PBD) are characterized by a high intake of foods of plant origin and the partial or total avoidance of animal products. The objective of the current study was to compile the evidence on types of PBD and its effect on the main modifiable cardio-metabolic risk factors (CMRF). Healthy and unhealthy PBD were found to exist. Some healthy PBDs were: vegetarian, mediterranean and DASH (Dietary Approaches to Stop Hypertension). These promote the intake of “healthy” plant-based foods (fruits, vegetables, legumes, seeds, nuts, whole grains, avocado, olive oil and / or canola) and a gradual reduction of all foods of animal origin, especially red and processed meats; avoiding “less healthy” plant-based foods (refined, fried cereals, pastry products, foods with added sugar). Unhealthy PBDs were characterized by a high intake of these “less healthy” foods, and are associated with greater cardiovascular risk, due to the low contribution of antioxidants, micronutrients, dietary fiber and unsaturated fats. Healthy PBDs can lower the risk of type 2 diabetes, high blood pressure, being overweight, and obesity. They have shown greater cardiovascular benefits compared to traditional diets, significantly reducing: HbA1c and fasting glycemia in diabetics; systolic and diastolic blood pressure in hypertensive and prehypertensive patients; body mass index in overweight / obese subjects and improves lipid profile in subjects with dyslipidemia. Healthy PBD patterns, such as vegetarian, Mediterranean, and DASH are recommended to prevent and treat CMRF.
