From Science Might Have Identified The Optimal Human Diet:
“Americans are notoriously unhealthy eaters. The so-called Western diet — one that adores meat, abhors fat, and can’t get enough of processed food — has dominated menus and mealtimes for nearly half a century and has become synonymous with obesity and metabolic dysfunction. Short of swallowing actual poison, it’s hard to imagine a more ruinous approach to eating than the one practiced by many U.S. adults.
If this story has a silver lining, it’s that the dreadful state of the average American’s diet has helped clarify the central role of nutrition in human health. A poor diet like the one popular in the West is strongly associated with an elevated risk for conditions of the gut, organs, joints, brain, and mind — everything from Type 2 diabetes and cancer to rheumatoid arthritis and depression.
“We’ve realized that diet is arguably the most important predictor of long-term health and well-being,” says James O’Keefe, MD, a cardiologist and medical director of the Duboc Cardio Health and Wellness Center at Saint Luke’s Mid America Heart Institute. “Most of the major health problems we deal with in America are connected to the ways we eat.”
From Healthy Eating:
What is a healthy diet?
“Eating a healthy diet is not about strict limitations, staying unrealistically thin, or depriving yourself of the foods you love. Rather, it’s about feeling great, having more energy, improving your health, and boosting your mood.
Healthy eating doesn’t have to be overly complicated. If you feel overwhelmed by all the conflicting nutrition and diet advice out there, you’re not alone. It seems that for every expert who tells you a certain food is good for you, you’ll find another saying exactly the opposite. The truth is that while some specific foods or nutrients have been shown to have a beneficial effect on mood, it’s your overall dietary pattern that is most important. The cornerstone of a healthy diet should be to replace processed food with real food whenever possible. Eating food that is as close as possible to the way nature made it can make a huge difference to the way you think, look, and feel.
By using these simple tips, you can cut through the confusion and learn how to create — and stick to — a tasty, varied, and nutritious diet that is as good for your mind as it is for your body.”
The fundamentals of healthy eating
“While some extreme diets may suggest otherwise, we all need a balance of protein, fat, carbohydrates, fiber, vitamins, and minerals in our diets to sustain a healthy body. You don’t need to eliminate certain categories of food from your diet, but rather select the healthiest options from each category.
Protein gives you the energy to get up and go — and keep going — while also supporting mood and cognitive function. Too much protein can be harmful to people with kidney disease, but the latest research suggests that many of us need more high-quality protein, especially as we age. That doesn’t mean you have to eat more animal products — a variety of plant-based sources of protein each day can ensure your body gets all the essential protein it needs. Learn more »
Fat. Not all fat is the same. While bad fats can wreck your diet and increase your risk of certain diseases, good fats protect your brain and heart. In fact, healthy fats — such as omega-3s — are vital to your physical and emotional health. Including more healthy fat in your diet can help improve your mood, boost your well-being, and even trim your waistline. Learn more »
Fiber. Eating foods high in dietary fiber (grains, fruit, vegetables, nuts, and beans) can help you stay regular and lower your risk for heart disease, stroke, and diabetes. It can also improve your skin and even help you to lose weight. Learn more »
Calcium. As well as leading to osteoporosis, not getting enough calcium in your diet can also contribute to anxiety, depression, and sleep difficulties. Whatever your age or gender, it’s vital to include calcium-rich foods in your diet, limit those that deplete calcium, and get enough magnesium and vitamins D and K to help calcium do its job.

Carbohydrates are one of your body’s main sources of energy. But most should come from complex, unrefined carbs (vegetables, whole grains, fruit) rather than sugars and refined carbs. Cutting back on white bread, pastries, starches, and sugar can prevent rapid spikes in blood sugar, fluctuations in mood and energy, and a build-up of fat, especially around your waistline.

Making the switch to a healthy diet
Switching to a healthy diet doesn’t have to be an all or nothing proposition. You don’t have to be perfect, you don’t have to completely eliminate foods you enjoy, and you don’t have to change everything all at once — that usually only leads to cheating or giving up on your new eating plan.
A better approach is to make a few small changes at a time. Keeping your goals modest can help you achieve more in the long term without feeling deprived or overwhelmed by a major diet overhaul. Think of planning a healthy diet as a number of small, manageable steps — like adding a salad to your diet once a day. As your small changes become habit, you can continue to add more healthy choices.”
From What is a Whole-Foods, Plant-Based Diet?
“There is no clear definition of a what constitutes a whole-foods, plant-based diet (WFPB diet). The WFPB diet is not necessarily a set diet — it’s more of a lifestyle.
This is because plant-based diets can vary greatly depending on the extent to which a person includes animal products in their diet.
Nonetheless, the basic principles of a whole-foods, plant-based diet are as follows:
- Emphasizes whole, minimally processed foods.
- Limits or avoids animal products.
- Focuses on plants, including vegetables, fruits, whole grains, legumes, seeds and nuts, which should make up the majority of what you eat.
- Excludes refined foods, like added sugars, white flour and processed oils.
- Pays special attention to food quality, with many proponents of the WFPB diet promoting locally sourced, organic food whenever possible.
For these reasons, this diet is often confused with vegan or vegetarian diets. Yet although similar in some ways, these diets are not the same.
People who follow vegan diets abstain from consuming any animal products, including dairy, meat, poultry, seafood, eggs and honey. Vegetarians exclude all meat and poultry from their diets, but some vegetarians eat eggs, seafood or dairy.
The WFPB diet, on the other hand, is more flexible. Followers eat mostly plants, but animal products aren’t off limits.
While one person following a WFPB diet may eat no animal products, another may eat small amounts of eggs, poultry, seafood, meat or dairy.”
