The Pegan Diet: Eating the Rainbow

The Pegan diet is a plant-rich approach to nutrition that incorporates quality animal protein and fats. However, the foundation of the diet is plant foods, which are nutrient-dense and loaded with beneficial chemicals linked to disease prevention. To eat a healthy diet, it is essential to consume plant foods from every color group, as different colors offer various health benefits. Red plant foods protect cells, orange foods boost fertility and mood control, yellow foods aid digestion, green foods protect blood vessels, and blue foods promote mood balance and neural health. By following the rainbow, you can give your body all the nutrients it needs to stay healthy.

Food for a Better Mood

In the midst of a global pandemic, eating well can help improve mental health. Researchers in nutritional psychology have found that a balanced diet rich in “brain foods” can enhance mood. A 2017 study showed that swapping processed, sugary, and starchy foods for whole foods can be up to 400% more effective in treating depression. To boost mood, reduce intake of refined sugars and carbohydrates, cut out late meals, and eat regularly during the day. Plant-based meals and brain foods like oily fish, seafood, and fermented foods can help support brain health.

In the face of a challenging and unprecedented year, millions of people around the world have experienced job loss, business closures, illness, and death. These headline-grabbing tragedies have understandably taken a toll on people’s mental health, with worry, boredom, and isolation contributing to a growing crisis. In fact, depression is now the fourth most common disease worldwide and the leading cause of disability.

However, a new discipline called nutritional psychology has shed light on a powerful tool for enhancing mental health: food. Research from universities like Harvard and Stanford have confirmed the link between diet and brain health, showing that a balanced diet rich in “brain foods” can enhance mood.

One 2017 study published in BMC Medicine found that swapping processed, sugary, and starchy foods for whole foods can be up to 400% more effective in treating depression. To improve mood, it’s important to reduce intake of refined sugars and carbohydrates, as these cause blood sugar levels to spike, impairing cognitive functioning. Additionally, late meals should be avoided, as they lead to calories being stored as fat rather than burned for energy. Eating regularly throughout the day is also important, as skipping meals can divert resources away from the brain.

The basis of a brain-boosting diet should consist of plant-based meals, with additional brain foods added in. Foods rich in omega-3s, magnesium, vitamin D, antioxidants, and B vitamins can all support brain health. Oily fish like sardines and mackerel, B12-loaded seafood such as oysters, and fermented foods like pickles, kimchi, and sauerkraut are all excellent choices.

By incorporating brain foods into their diets and adopting healthy eating habits, individuals can improve both their physical and mental health during these trying times.

The 75 Percent Rule

Learn the difference between slow and refined carbs, their impact on blood sugar, and how to balance their intake to maintain cognitive health.

Carbohydrates are essential for our body’s energy needs. However, not all carbs are created equal. Refined carbs such as white bread and pasta contain little to no nutritional value, causing blood sugar levels to rise rapidly and leading to weight gain and diabetes. Slow carbs, on the other hand, are essential for nourishing our body, and they help in releasing energy slowly without disrupting blood sugar levels.

To maintain a healthy cognitive state, it is imperative to know and understand the difference between slow and refined carbs. Slow carbs are plant-based foods, packed with essential vitamins, minerals, fiber, phytochemicals, and other nutrients essential for nourishing our body. Non-starchy slow carbs such as broccoli, bok choy, tomatoes, cauliflower, mushrooms, zucchini, carrots, and onions are excellent examples that can be consumed in abundance.

Starchy slow carbs such as sweet potato, yams, squash, and pumpkins should be included in the remaining 25% of our meals. As per the 75 percent rule, slow carbs should constitute three-quarters of the food we eat, which reduces the risk of blood sugar spikes and other related health issues.

Overall, the key takeaway is that it is not necessary to avoid carbohydrates, but the focus should be on consuming more slow carbs than refined carbs. By following the 75 percent rule, one can effortlessly maintain cognitive health and, at the same time, enjoy a balanced and healthy diet.

Ethical and Healthy Meat Consumption

Ethics and health are two crucial factors to consider when it comes to consuming meat. While vegans are against meat consumption, pegans believe it’s not a black-and-white issue. However, the kind of meat one consumes matters. Factory-farmed red meat is ethically and environmentally disastrous. The solution lies in regenerative farming, which is a science-based approach to producing nutrient-rich food while restoring damaged ecosystems. This results in lower carbon emissions, better soil, and ecosystem health. Furthermore, providing animals with space and time in natural meadows and improved diets reduces their methane emissions. According to the UN, converting damaged agricultural lands to regenerative farming globally would halt climate change for two decades. This means there are good ethical arguments for including certain kinds of meat in our diets.

The Benefits of High-Quality Meat

Not all meat is created equal, similar to tomatoes. The quality of the meat you consume is crucial to its health effects. Grass-fed meat contains a wide range of health-promoting nutrients like phytochemicals, omega-3 profiles, and CLA, shown to boost metabolism and fight cancer. Similarly, consuming meat as part of a whole foods-based diet rather than a sugary, carb-based diet provides better health outcomes. This makes context a crucial factor in determining the health impacts of meat consumption.
