Which Diets Are Best For Your Health?

Author: Dr. Stephen Chaney

Is it hot enough yet? I’m not going to take a stand in the global warming debate. But I will say this summer has been extraordinarily hot – even for North Carolina.

So, what can we do about it? I will list some options below. But with “tongue in cheek” I will give voice to both sides of each option.

We can elect politicians of our choice and hope they have the wisdom to balance reductions in global warming with the energy needs of our country – but there has been little evidence of that wisdom from either end of the political spectrum.

We can purchase electric cars – despite their cost, limited range, and long refueling times.

We can recycle – even though most of what we recycle ends up in regular trash.

We can turn up our thermostats in summer and down in winter – and choose to swelter in summer and shiver in winter.

We can change our diet – but wait. Could this be a win no matter what our views are on climate change? Could the same diets that are better for the planet also be better for our health?

That is the hypothesis today’s study (K. O’Malley et al, The American Journal of Clinical Nutrition, 117: 701-708, 2023) set out to test.

How Was The Study Done?

The investigators analyzed 24-hour dietary recall data from 16,412 participants from the 2005 – 2010 NHANES survey. NHANES (National Health and Nutrition Examination Survey) is an ongoing, nationally representative, survey to measure the health and nutrition status of the US population. This investigation used data collected between 2005 and 2010.

The dietary data were used to categorize the intake of individual participants into different diets as follows:

Vegan – plant foods only.
Vegetarian – includes eggs and dairy but excludes meat.
Pescatarian – includes fish as the major source of meat.
Paleo – excludes grains, legumes, and dairy.
Keto – excludes grains, legumes, fruits, and starchy vegetables.
Omnivore – Any diet not included in the categories above.

The omnivore diet was further divided to identify people following the DASH and Mediterranean diets.

The environmental impact of each diet was calculated based on the amount of CO₂ and methane produced in the production of the foods included in the diet.

The impact on our health of each diet was calculated based on the Alternative Healthy Eating Index.

The Healthy Eating Index was first developed in 1995 as tool to gauge how well a diet followed the Dietary Guidelines for Americans established by the Department of Health & Human Services and the USDA.

The Alternative Healthy Eating Index was first developed in 2002 to include a wider range of foods and to better predict the effect of diet on chronic diseases based on clinical studies of health outcomes.

Each of these indices are regularly updated as more data become available.

Which Diets Are Best For the Planet?

I have put the data in a graphical format, so it is easier to visualize.The vertical axis is greenhouse gas emissions expressed as kg of CO₂ equivalents per 1,000 calories (The term CO₂ equivalents is used because cows and sheep produce methane which is a much more potent greenhouse gas than CO₂). Lower is better.

On the horizontal axis the diets from left to right are vegan, vegetarian, pescatarian, paleo, keto, omnivore, DASH, and Mediterranean. The diets with the least greenhouse gas emissions are shown in green (the greener the better), and the diets with the most greenhouse gas emissions are shown in orange and red.

Which Diets Are Best For Your Health?

Once again, I have chosen a graphical representation.

The vertical axis is the Alternative Healthy Eating Index. In this case, higher is better.

The color score is the same as above. However, I would note that:

Fish is the main animal protein source in the pescatarian diet. I suspect that the vegan and vegetarian diets would score just as high as the pescatarian diet in the Alternative Healthy Eating Index if an omega-3 supplement was taken along with the diets.

The Alternative Healthy Eating Index is weighted heavily on clinical studies showing that a particular diet reduces the risk of heart disease, diabetes, and/or cancer. That is likely why the DASH diet ranks so high. It was designed to decrease the risk of hypertension. Because of that there have been dozens of studies showing it reduces the risk of strokes and heart attacks.

The available evidence suggests that the Mediterranean diet is just as effective as the DASH diet at reducing the risk of strokes, heart attacks, and diabetes. But we do not yet have as many studies looking at the effect of the Mediterranean diet on those diseases. Based on the currently available evidence, I consider the Mediterranean diet to be just as healthy as the DASH diet.

Finally, I would like to point out the obvious. This and other studies show that the same diets that are good for the planet are good for our health.

For example, the authors estimated:

For any given day, if a third of omnivores in the United States switched to a vegetarian diet, it would be equivalent to eliminating 340 million passenger miles in gas-powered vehicles.

If this change were implemented year-round, it would amount to almost 5% of the reductions in greenhouse gas emissions needed to meet the original US targets in the Paris accords.

For those omnivores who made the switch to a vegetarian diet, it would improve diet quality by 6%.

Of course, if all omnivores in the United States switched to a vegetarian diet, these percentages would be tripled, but that is wildly unrealistic.

What Does This Study Mean For You?

The take home lesson from this study is clear.

If your primary concern is climate change, choose the planet-healthy diet that best fits your food preferences and lifestyle. [The ones with the lowest greenhouse gas emissions are shown in green in the first graph above – the greener, the better.] Any of these diets will also be good for your health.

If your primary concern is health, choose the healthy diet that best fits your food preferences and lifestyle. [The ones with the highest Alternate Healthy Eating Index are shown in green in the second graph above – the greener, the better.] Any of these diets will also be good for the planet.

The Bottom Line

A recent study compared 8 popular diets (vegan, vegetarian, pescatarian, paleo, keto, omnivore, DASH, and Mediterranean) with respect to their impact on the environment and on your health.

The results were clear-cut. The diets that were best for the planet were best for your health and vice-versa.

For example, the authors estimated:

For any given day, if a third of omnivores in the United States switched to a vegetarian diet, it would be equivalent to eliminating 340 million passenger miles in gas-powered vehicles.

If this change were implemented year-round, it would amount to almost 5% of the reductions in greenhouse gas emissions needed to meet the original US targets in the Paris accords.

For those omnivores who made the switch to a vegetarian diet, it would improve diet quality by 6%.

My posts and “Health Tips From the Professor” articles carefully avoid claims about any brand of supplement or manufacturer of supplements. However, I am often asked by representatives of supplement companies if they can share them with their customers.

My answer is, “Yes, as long as you share only the article without any additions or alterations. In particular, you should avoid adding any mention of your company or your company’s products. If you were to do that, you could be making what the FTC and FDA consider a “misleading health claim” that could result in legal action against you and the company you represent.

Can Diet Affect The Health Of Our Planet?

Author: Dr. Stephen Chaney

Earth Day was yesterday. So, it is time for my annual reminder that what you eat affects a lot more than just your health. It affects the health of our planet. Once again, it’s time to ask yourself, “Is my diet destroying the planet?

The commission carefully evaluated diet and food production methods and asked three questions:

Are they good for us?

Are they good for the planet?

Are they sustainable? Will they be able to meet the needs of the projected population of 10 billion people in 2050 without degrading our environment.

The commission described the typical American diet as a “lose-lose-lose diet”. It is bad for our health. It is bad for the planet. And it is not sustainable.

In its place they carefully designed their version of a primarily plant-based diet they called a “win-win-win diet”. It is good for our health. It is good for the planet. And it is sustainable.

In their publication they refer to their diet as the “universal healthy reference diet” (What else would you expect from a committee?). However, it has become popularly known as the “Planetary Diet”.

I have spoken before about the importance of a primarily plant-based diet for our health. In that context it is a personal choice. It is optional.

However, this report is a wake-up call. It puts a primarily plant-based diet in an entirely different context. It is essential for the survival of our planet. It is no longer optional.

If you care about our environment…If you care about saving our planet, there is no other choice.

How Was The Study Done?

The publication (W. Willet et al, The Lancet, 393, issue 10170, 447-492, 2019) was the report of the EAT-Lancet Commission on Healthy Diets from Sustainable Food Systems. This Commission convened 30 of the top experts from across the globe to prepare a science-based evaluation of the effect of diet on both health and sustainable food production through the year 2050. The Commission included world class experts on healthy diets, agricultural methods, climate change, and earth sciences. The Commission reviewed 356 published studies in preparing their report.

Can Diet Affect The Health Of Our Planet?

When they looked at the effect of food production on the environment, the Commission concluded:

“Strong evidence indicates that food production is among the largest drivers of global environmental change.” Specifically, the commission reported:

- Agriculture occupies 40% of global land (58% of that is for pasture use).

- Food production is responsible for 30% of global greenhouse gas emissions and 70% of freshwater use.

- Conversion of natural ecosystems to croplands and pastures is the largest factor causing species to be threatened with extinction. Specifically, 80% of extinction threats to mammals and bird species are due to agricultural practices.

- Overuse and misuse of nitrogen and phosphorous in fertilizers causes eutrophication. In case you are wondering, eutrophication is defined as the process by which a body of water becomes enriched in dissolved nutrients (such as phosphates from commercial fertilizer) that stimulate the growth of algae and other aquatic plant life, usually resulting in the depletion of dissolved oxygen. This creates dead zones in lakes and coastal regions where fish and other marine organisms cannot survive.

About 60% of world fish stocks are fully fished and more than 30% are overfished. Because of this, catch by global marine fisheries has been declining since 1996.

“Reaching the Paris Agreement of limiting global warming…is not possible by only decarbonizing the global energy systems. Transformation to healthy diets from sustainable food systems is essential to achieving the Paris Agreement.”

The world’s population is expected to increase to 10 billion by 2050. The current system of food production is unsustainable.

When they looked at the effect of the foods we eat on the environment, the Commission concluded:

Beef and lamb are the biggest contributors to greenhouse gas emissions and land use.

- The concern about land use is obvious because of the large amount of pastureland required to raise cattle and sheep.

- The concern about greenhouse gas emissions is because cattle and sheep are ruminants. They not only breathe out CO₂, but they also release methane into the atmosphere from fermentation in their rumens of the food they eat. Methane is a potent greenhouse gas, and it persists in the atmosphere 25 times longer than CO₂.

The single most important thing we can do as individuals to reduce greenhouse gas emissions is to eat less beef and lamb. [Note: grass fed cattle produce more greenhouse gas emissions than cattle raised on corn because they require 3 years to bring to market rather than 2 years.]

- In contrast, plant crops reduce greenhouse gas emissions by removing CO₂ from the atmosphere.

In terms of energy use beef, lamb, pork, chicken, dairy, and eggs all require much more energy to produce than any of the plant foods.

In terms of eutrophication of our lakes and oceans, beef, lamb, and pork all cause much more eutrophication than any plant food. Dairy and eggs cause more eutrophication than any plant food except fruits.

Eat Green

In the words of the Commission: “[The Planetary Diet] largely consists of vegetables, fruits, whole grains, legumes, nuts, and unsaturated oils. It includes a low to moderate amount of seafood, poultry, and eggs. It includes no or a very low amount of red meat, processed meat, sugar, refined grains, and starchy vegetables.”

When described in that fashion it sounds very much like other healthy diets such as semi-vegetarian, Mediterranean, DASH, and Flexitarian. However, what truly distinguishes it from the other diets is the restrictions placed on the non-plant portion of the diet to make it both environmentally friendly and sustainable. Here is a more detailed description of the diet:

It starts with a vegetarian diet. Vegetables, fruits, beans, nuts, soy foods, and whole grains are the foundation of the diet.

It allows the option of adding one serving of dairy a day (It turns out that cows produce much less greenhouse emissions per serving of dairy than per serving of beef. That’s because cows take several years to mature before they can be converted to meat, and they are emitting greenhouse gases the entire time).

It allows the option of adding one 3 oz serving of fish or poultry or one egg per day.

It allows the option of swapping seafood, poultry, or egg for a 3 oz serving of red meat no more than once a week. If you want a 12 oz steak, that would be no more than once a month.

This is obviously very different from the way most Americans currently eat. According to the Commission:

“This would require greater than 50% reduction in consumption of unhealthy foods, such as red meat and sugar, and greater than 100% increase in the consumption of healthy foods, such as nuts, fruits, vegetables, and legumes”.

“In addition to the benefits for the environment, “dietary changes from current diets to healthy diets are likely to substantially benefit human health, averting about 10.8-11.6 million deaths per year globally.”

What Else Did The Commission Recommend?

In addition to changes in our diets, the Commission also recommended several changes in the way food is produced. Here are a few of them.

Reduce greenhouse gas emissions from the fuel used to transport food to market.

2) Reduce food losses and waste by at least 50%.

3) Make radical improvements in the efficiency of fertilizer and water use. In terms of fertilizer, the change would be two-fold:

- In developed countries, reduce fertilizer use and put in place systems to capture runoff and recycle the phosphorous.

- In third world countries, make fertilizer more available so that crop yields can be increased, something the Commission refer to as eliminating the “yield gap” between third world and developed countries.

4) Stop the expansion of new agricultural land use into natural ecosystems and put in place policies aimed at restoring and re-foresting degraded land.

5) Manage the world’s oceans effectively to ensure that fish stocks are used responsibly and global aquaculture (fish farm) production is expanded sustainability.

What we can do: While most of these are government level policies, we can contribute to the first three by reducing personal food waste and purchasing organic produce locally whenever possible.

What Does This Mean For You?

If you are a vegan, you are probably asking why the Commission did not recommend a completely plant-based diet. The answer is that a vegan diet is perfect for the health of our planet. However, the Commission wanted to make a diet that was as consumer friendly as possible and still meet their goals of a healthy, environmentally friendly, and sustainable diet.

If you are eating a typical American diet or one of the fad diets that encourage meat consumption, you are probably wondering how you can ever make such drastic changes to your diet. The answer is “one step at a time”. If you have read the Forward to my books “Slaying The Food Myths” or “Slaying the Supplement Myths”, you know that my wife and I did not change our diet overnight. Our diet evolved to something very close to the Planetary Diet over a period of years.

The Commission also purposely designed the Planetary Diet so that you “never have to say never” to your favorite foods. Three ounces of red meat a week does not sound like much, but it allows you a juicy steak once a month.

Sometimes you just need to develop a new mindset. As I shared in my books, my father prided himself on grilling the perfect steak. I love steaks, but I decided to set a few parameters. I don’t waste my red meat calories on anything besides filet mignon at a fine restaurant. It must be a special occasion, and someone else must be buying. That limits it to 2-3 times a year. I still get to enjoy good steak, and I stay well within the parameters of the Planetary diet.

Develop your strategy for enjoying some of your favorite foods within the parameters of the Planetary Diet and have fun with it.

The Bottom Line

Is your diet destroying the planet? This is not a new question, but a recent commission of international scientists has conducted a comprehensive study into our diet and its effect on our health and our environment. Their report serves as a dire warning of what will happen to us and our planet if we don’t change our ways.

The Commission carefully evaluated diet and food production methods and asked three questions:

What Is The Planetary Diet?

Author: Dr. Stephen Chaney

Earth Day was last Thursday. You have recommitted to saving the planet. You plan to recycle, conserve energy, and turn in your gas guzzler for an energy efficient car. But what about your diet? Is your diet destroying the planet?

This is not a new question, but a recent commission of international scientists has conducted a comprehensive study into our diet and its effect on our health and our environment. Their report (W. Willet et al, The Lancet, 393, issue 10170, 447-492, 2019) serves as a dire warning of what will happen if we don’t change our ways.
