What is plant-based nutrition?

A plant-based diet focuses on eating foods that mainly come from plants. It includes vegetables, fruit, whole grains, seeds, nuts, beans, legumes, and oils. However, there are varying interpretations of what’s involved with plant-based eating.

Some define it as a vegetarian or vegan diet, while others see it as including more plant-based nutrition and less meat and dairy in their eating plans. Technically, all these definitions are correct.

The central idea of a plant-based diet and nutrition is to place more emphasis on incorporating plant-based foods into your everyday eating plan while reducing or eliminating foods from animals and fish. There is no rule that meat, dairy, or seafood is completely off-limits as long as you’re focused on consuming a bigger variety and number of plant-based foods.

Although refined sugars, some vegetable fats, and white flour can be considered plant-based, these products along with other processed foods, chemicals, preservatives, and artificial additives should be avoided to achieve a healthy, balanced diet.

Why has it become more popular?

There is a growing awareness around the preservation of animals, the environmental impact, disease prevention, and weight management that is fueling the drive to plant-based diets. Overfishing and mass livestock farming is inhumane and negatively impacts the environment and is depleting the oceans of marine life.

The widespread use of chemicals and animal antibiotics increases the risk of disease in humans. Processed meats contain nitrites and nitrates that are carcinogenic, and animal fats contribute to weight-related disorders when consumed in high quantities.

Additionally, the escalating rates of methane released into the atmosphere by livestock also place a heavy footprint on the environment. Another factor is the affordability as organic and free-range meat and dairy products are becoming more expensive.
