Human beings grow their food or hunt. We buy our food at the market, local grocery, or supermarket. Most humans follow an omnivorous diet (a diet where the source of food is from both pants and animals).

Most of our food originate from plants. The animals used as food sources are raised by feeding them food derived from plants.

A Healthy Plate

A good method to help you eat healthy is the “Healthy Plate“. This method is very easy and helps you control your serving sizes when you place food on your plate. There is no need to count the calories.

Place your food in a 7-inch plate. For your parents, they will have to use a 9-inch plate.

First, divide the plate in half. Then fill that half with vegetables.

There are two types of vegetables starchy like potatoes, corn, peas or plantains, and non starchy like zucchini, broccoli, cucumbers, carrots, or
salad. If you have diabetes, fill this side of the plate with non-starchy vegetables.

Then the other half will comprise of a quarter whole grains or starchy vegetables. If you are diabetic, you should choose starches with more fiber such as brown rice, corn, beans, or wholewheat pasta. In the other quarter add some lean protein like tofu, grilled fish or chicken.

Finally, add a drink like unsweetened coffee, tea, or a glass of millk, but remember that 8 ounces of milk affects your blood sugar just as another tortilla or slice of bread would. You can choose water with a squeeze of lemon or lime.
