a. True
b. False

Hint: It includes fruit, vegetables, grains, dairy products, and protein. It doesn't include an excessive amount of or deficient of any reasonable food.

Complete answer:
A healthy diet or diet may be a diet (what you eat) that contains the proper amounts of all the food groups. Eating wrong amounts of a food group, whether it's an excessive amount of or deficient, is called an imbalanced diet. A healthy diet is one that has more foods that come from plants and fewer convenience foods.
Basic nutrition:
• Basic nutrition begins with a diet supporting the most important food groups that has vegetables, whole grains, low-fat dairy products. It should also contain lean protein like beans, legumes, nuts and seeds plus healthy fats.
• A basic nutrition plan should include guidelines for the way much food from each group to eat.
• A basic food plan should support a person's budget, lifestyle and (healthy) preferences.
• Drink water. Drink fewer Soft drinks, energy drinks and sports drinks, which usually contain sugar.
• Read the food labels to determine what's within the foods. As an example, labels usually show what foods are lower in sodium like in soup, bread, and frozen meals.
• A healthy diet should include seafood (such as salmon, tuna, and trout) and shellfish (such as crab, mussels, and oysters). Seafood has protein, minerals, and omega-3 fatty acids which are heart-healthy.
• Basic nutrition should contain balanced amounts of carbohydrates for energy. Carbohydrates are one in all the three macronutrients within the human diet (fat and protein are the opposite two).
• A healthy diet can replace dieting for weight loss. Eating healthy, together with physical exertion and practicing moderation, can result in better health within the future.

Therefore, the answer is a, true!
