What Does Living Plant-Based Really Mean?

The term plant-based might be interpreted to be a diet that is centered on plants but perhaps not exclusively plants. In actuality, the ideal is eating only foods gathered from plant sources. Added to the basic tenet of plant-sourced foods is the goal of eating only whole plant foods or minimally processed plant foods. Processing robs foods of vital nutrients and adds unhealthy ingredients such as sugar, fat and oil. Plant oils themselves, extracted from their natural and healthy high nutrient, high fiber whole food “packages” are highly processed foods. A whole-foods plant-based diet is naturally low in UNHEALTHY oils and fats and refined sugars. Added plant oils are to be avoided completely or at least minimized. Though a whole-food plant-based diet is low in ADDED fat it still includes more than enough HEALTHY fat through the consumption of nuts and seeds and vegetables themselves. A plant-based diet is all about eating as much health-promoting food as you can while eliminating or at least minimizing those foods that can sabotage your health.

Just a simple change….
The change to a whole-food plant-based lifestyle is a simple choice that makes it easy to eat to feel vigorous and energetic, to lose weight, to lower cholesterol, to enhance athletic performance, to have less impact on the environment and to prevent and even reverse many of our common “lifestyle diseases”. At the same time you will discover a world full of delicious and satisfying food that is nutrient-dense, not calorie dense (more on this later). You can enjoy eating without guilt until you are full. You can continue to enjoy many of the favourite foods that you enjoy on your present diet while at the same time discovering delectable new tastes to savour. Most importantly, you will avoid putting food in your body that, by its very nature, contains nutrients that not only do not promote health in humans, but also can cause harm.

So, what does this mean in practical terms?

Do eat vegetables, fruits, legumes, whole grains, nuts, seeds and herbs and spices.

Do not eat all foods from animal sources including;
– all meat including beef, pork, deer, moose, poultry, seafood, processed meats
– dairy products including milk, cheese, yogurt
– eggs

Do not eat processed foods including;
– conventional cakes, pastries, cookies, sugary cereals and any other food made with refined flour or sugar, so-called “convenience foods”, savoury snacks such as potato chips
– sugary carbonated drinks
– all added fats including oils in liquid form (all vegetable oils – corn oil, peanut oil, safflower oil, olive oil) and oils in solid form (butter, margarine, coconut oil)

Limit the consumption of added sugar. (Sugar that is a part of a fruit or vegetable is healthy and can be eaten liberally.)

Extras for ensured health….
To ensure that your body is receiving everything it needs for robust health there are three recommended supplements. The first is B12 which is difficult to get if you don’t eat animals. Many meat-eaters are also low in B12 due to issues with absorption. It is a good idea for everyone, no matter what their diet, to get their B12 levels checked and to have a known source of B12. A recommended dose is 1500 to 2500 mcg once a week or 100 to 250 mcg daily (4). Omega-3s are at a controversial stage in research right now. Though they seem to have no beneficial effect on heart disease, they do play a role in brain cognition. People vary in their ability to convert omega-3s found in plants to the essential long-chain fatty acids, DHA and EPA. It is a good idea to take a low dose omega-3 supplement. Try to find an algae source of omega 3 which will prevent exposure to contaminants found in many fish sources. A dose of 250 mg of DHA and/or EPA daily or at least 3 or 4 times a week is advised (5). Last but not least, those of us living in Canada and the northern United States tend to have low Vitamin D levels. At higher latitudes we do not experience enough sunlight year round to allow our bodies to produce sufficient vitamin D. No matter what our diet, we northerners should ingest a supplemental source of Vitamin D at least during the winter months. A safe dose of Vitamin D is 1000 units daily (6). These nutrients will be discussed in more detail in later blogs.

In the real world….
Kaiser Permanente is the largest managed health care organization in the United States whose large umbrella includes over 18,000 physicians, 51,000 nurses, forty medical centers and over 600 medical offices. In 2013 they published a guide for their patients called “The Plant-Based Diet: A Healthier Way to Eat” in which they state “If you find you cannot do a plant-based diet 100% of the time, then aim for 80%. Any movement toward more plants and fewer animal products can improve your health” (1). In a nutshell, the fewer animal products and processed foods in the diet the better. (2)

You may hear other terms for this healthy lifestyle. Plant-strong, plant-pure, plant-based – they all mean the same thing. Eat to enjoy vibrant health throughout life.

A word of caution….
If you are taking medication, especially for hypertension (high blood pressure) or type 2 diabetes, please make your eating changes in partnership with your physician. It is easy to underestimate the power of plant-based eating but changes in your health can be dramatic. Within two weeks of adopting a plant-based diet, the insulin needs of a type 2 diabetic can drop in half and the same can happen with oral medications. If you continue taking insulin at the same dose while your body is reviving you could experience extremely low blood sugar. Blood pressure also can decrease quickly. Close monitoring in conjunction with your doctor may be needed to detect low blood sugar levels and low blood pressure (3).

Why I don’t like the term “vegan”…
A whole-food plant-based diet can be vegan but not all vegan diets are necessarily healthy. The term vegan was created in 1944 by the Vegan Society with an abiding creed to eat nothing that originates from an animal source. Some vegans also refuse to use products from animal sources such as leather, fur, honey, rennet, some cosmetics and any products tested on animals. Veganism places no particular importance on the consumption of healthy whole foods. Processed foods could constitute a major part of an essentially unhealthy vegan diet.
