Healthy eating is one of the best things you can do to prevent and control health problems such as heart disease, high blood pressure, type 2 diabetes, and some types of cancer. The low-carb, whole-food diet is perfect for people who need to lose weight, optimize health, and lower their risk of disease. It’s flexible, allowing you to fine-tune your carb intake depending on your goals. This diet is high in vegetables, meat, fish, eggs, fruits, nuts, and fats but low in starches, sugars, and processed foods. The Mediterranean diet is an excellent diet that has been thoroughly studied. It’s particularly effective for heart disease prevention. It emphasizes foods that were commonly eaten around the Mediterranean region during the 20th century and earlier. As such, it includes plenty of vegetables, fruits, fish, poultry, whole grains, legumes, dairy products, and extra virgin olive oil.
