What Is the Dr. Sebi Alkaline Diet, and Is It Beneficial?
It's claimed to rejuvenate your cells by eliminating toxic waste through alkalizing your blood.
The diet relies on eating a short list of approved foods along with many supplements.
This article reviews the benefits and downsides of the Dr. Sebi diet and whether scientific evidence backs up its health claims.
What is the Dr. Sebi Diet?
This diet is based on the African Bio-Mineral Balance theory and was developed by the self-educated herbalist Alfredo Darrington Bowman — better known as Dr. Sebi. Despite his name, Dr. Sebi was not a medical doctor and did not hold a PhD.
He designed this diet for anyone who wishes to naturally cure or prevent disease and improve their overall health without relying on conventional Western medicine.
According to Dr. Sebi, disease is a result of mucus build-up in an area of your body. For example, a build-up of mucus in the lungs is pneumonia, while excess mucus in the pancreas is diabetes.
He argues that diseases cannot exist in an alkaline environment and begin to occur when your body becomes too acidic.
By strictly following his diet and using his proprietary costly supplements, he promises to restore your body's natural alkaline state and detoxify your diseased body.
Originally, Dr. Sebi claimed that this diet could cure conditions like AIDS, sickle cell anemia, leukemia, and lupus. However, after a 1993 lawsuit, he was ordered to discontinue making such claims.
The diet consists of a specific list of approved vegetables, fruits, grains, nuts, seeds, oils, and herbs. As animal products are not permitted, the Dr. Sebi diet is considered a vegan diet.
Sebi claimed that for your body to heal itself, you must follow the diet consistently for the rest of your life.
Finally, while many people insist that the program has healed them, no scientific studies support these claims.
The Dr. Sebi diet emphasizes consuming foods and supplements that supposedly decrease disease-causing mucus by achieving an alkaline state in your body.
How to Follow the Dr. Sebi Diet
The rules of the Dr. Sebi diet are very strict and outlined on his website.
According to Dr. Sebi's nutritional guide, you must follow these key rules:
- Rule 1. You must only eat foods listed in the nutritional guide.
- Rule 2. Drink 1 gallon (3.8 liters) of water every day.
- Rule 3. Take Dr. Sebi's supplements an hour before medications.
- Rule 4. No animal products are permitted.
- Rule 5. No alcohol is allowed.
- Rule 6. Avoid wheat products and only consume the "natural-growing grains" listed in the guide.
- Rule 7. Avoid using a microwave to prevent killing your food.
- Rule 8. Avoid canned or seedless fruits.
There are no specific nutrient guidelines. However, this diet is low in protein, as it prohibits beans, lentils, and animal and soy products. Protein is an important nutrient needed for strong muscles, skin, and joints (1Trusted Source, 2Trusted Source).
Additionally, you're expected to purchase Dr. Sebi's cell food products, which are supplements that promise to cleanse your body and nourish your cells.
It's recommended to buy the "all-inclusive" package, which contains 20 different products that are claimed to cleanse and restore your entire body at the fastest rate possible.
Besides this, no specific supplement recommendations are provided. Instead, you're expected to order any supplement that matches your health concerns.
For example, the "Bio Ferro" capsules claim to treat liver issues, cleanse your blood, boost immunity, promote weight loss, aid digestive issues, and increase overall well-being.
Furthermore, the supplements don't contain a complete list of nutrients or their quantities, making it difficult to know whether they will meet your daily needs.
The Dr. Sebi diet has eight main rules that must be followed. They mainly focus on avoiding animal products, ultra-processed food, and taking his proprietary supplements.
Can It Help You Lose Weight?
While Dr. Sebi's diet is not designed for weight loss, you may lose weight if you follow it.
The diet discourages eating a Western diet, which is high in ultra-processed foods and loaded with salt, sugar, fat, and calories (3Trusted Source).
A 12-month study in 65 people found that those who followed an unlimited whole-food, low-fat, plant-based diet lost significantly more weight than people who did not follow the diet (5Trusted Source).
At the 6-month mark, those on the diet had lost an average of 26.6 pounds (12.1 kg), compared with 3.5 pounds (1.6 kg) in the control group (5Trusted Source).
Furthermore, most foods on this diet are low in calories, except for nuts, seeds, avocados, and oils. Therefore, even if you ate a large volume of approved foods, it's unlikely that it would result in a surplus of calories and lead to weight gain.
However, very-low-calorie diets usually cannot be maintained long term. Most people who follow these diets regain the weight once they resume a normal eating pattern (6Trusted Source).
Since this diet does not specify quantities and portions, it's difficult to say whether it will provide enough calories for sustainable weight loss.
The Dr. Sebi diet is not designed for weight loss but is very low in calories and limits processed food. Therefore, you may lose some weight if you follow this diet.
Potential Benefits of the Dr. Sebi Diet
One benefit of the Dr. Sebi diet is its strong emphasis on plant-based foods.
The diet promotes eating a large number of vegetables and fruit, which are high in fiber, vitamins, minerals, and plant compounds.
Furthermore, most people are not eating enough produce. In a 2017 report, 9.3% and 12.2% of people met the recommendations for vegetables and fruit, respectively (10Trusted Source).
Moreover, the Dr. Sebi diet promotes eating fiber-rich whole grains and healthy fats, such as nuts, seeds, and plant oils. These foods have been linked to a lower risk of heart disease (11Trusted Source).
Finally, diets that limit ultra-processed foods are associated with better overall diet quality (12Trusted Source).
The Dr. Sebi diet emphasizes eating nutrient-rich vegetables, fruits, whole grains, and healthy fats, which may decrease your risk of heart disease, cancer, and inflammation.
Downsides of the Dr. Sebi Diet
Keep in mind that there are several drawbacks to this diet.
A major downside of Dr. Sebi's diet is that it restricts large groups of food, such as all animal products, wheat, beans, lentils, and many types of vegetables and fruit.
In fact, it's so strict that it only allows specific types of fruit. For example, you're allowed to eat cherry or plum tomatoes but not other varieties like beefsteak or roma tomatoes.
Moreover, following such a restrictive diet is not enjoyable and may lead to a negative relationship with food, especially since this diet vilifies foods that are not listed in the nutrition guide (13Trusted Source).
Finally, this diet encourages other negative behaviors, such as using supplements to achieve fullness. Given that supplements are not a major source of calories, this claim further drives unhealthy eating patterns (13Trusted Source).
Lacks Protein and Other Essential Nutrients
The foods listed in Dr. Sebi's nutrition guide can be an excellent source of nutrition.
However, none of the permitted foods are good sources of protein, an essential nutrient for skin structure, muscle growth, and the production of enzymes and hormones (2Trusted Source, 14Trusted Source, 15Trusted Source).
Only walnuts, Brazil nuts, sesame seeds, and hemp seeds are permitted, which aren't great sources of protein. For example, 1/4 cup (25 grams) of walnuts and 3 tbsp (30 grams) of hemp seeds provide 4 grams and 9 grams of protein, respectively (16, 17).
To meet your daily protein needs, you would need to eat extremely large portions of these foods.
Though foods in this diet are high in certain nutrients, such as beta carotene, potassium, and vitamins C and E, they're low in omega-3, iron, calcium, and vitamins D and B12, which are common nutrients of concern for those following a strictly plant-based diet (18Trusted Source).
Dr. Sebi's website states that certain ingredients in his supplements are proprietary and not listed. This is concerning, as it's unclear which nutrients you're getting and how much, making it difficult to know whether you'll meet your daily nutrient needs.
Not Based on Real Science
One of the biggest concerns with Dr. Sebi's diet approach is the lack of scientific evidence to support it.
He states that the foods and supplements in his diet control acid production in your body. However, the human body strictly regulates acid-base balance to keep blood pH levels between 7.36 and 7.44, naturally making your body slightly alkaline (19Trusted Source).
In rare cases, such as ketoacidosis from diabetes, blood pH can go out of this range. This can be fatal without immediate medical attention (20Trusted Source).
The Dr. Sebi diet may promote weight loss but is very restrictive and low in many essential nutrients, such as protein, omega-3, iron, calcium, and vitamins D and B12. It also ignores your body's natural ability to regulate blood pH levels.
Foods to Eat
Dr. Sebi's nutrition guide details specific foods allowed on the diet, including:
- Fruits: apples, cantaloupe, currants, dates, figs, elderberries, papayas, berries, peaches, soft jelly coconuts, pears, plums, seeded key limes, mangoes, prickly pears, seeded melons, Latin or West Indies soursop, tamarind.
- Vegetables: avocado, bell peppers, cactus flower, chickpeas, cucumber, dandelion greens, kale, lettuce (except iceberg), mushrooms (except shiitake), okra, olives, sea vegetables, squash, tomatoes (only cherry and plum), zucchini.
- Grains: fonio, amaranth, Khorasan wheat (kamut), rye, wild rice, spelt, teff, quinoa.
- Nuts and Seeds: Brazil nuts, hemp seeds, raw sesame seeds, raw tahini butter, walnuts.
- Oils: avocado oil, coconut oil (uncooked), grapeseed oil, hempseed oil, olive oil (uncooked), sesame oil.
- Herbal teas: elderberry, chamomile, fennel, tila, burdock, ginger, raspberry.
- Spices: oregano, basil, cloves, bay leaf, dill, sweet basil, achiote, cayenne, habanero, tarragon, onion powder, sage, pure sea salt, thyme, powdered granulated seaweed, pure agave syrup, date sugar.
In addition to tea, you are allowed to drink water.
Plus, you may eat permitted grains in the form of pasta, cereal, bread or flour. However, any food leavened with yeast or baking powder is banned.
This diet has a very strict list of allowed foods. Foods that are not included in this list should be avoided.
Foods to Avoid
Any foods that are not included in the Dr. Sebi nutrition guide are not permitted, such as:
- canned fruit or vegetables
- seedless fruit
- red meat
- soy products
- processed food, including take-out or restaurant food
- fortified foods
- sugar (besides date sugar and agave syrup)
- yeast or foods risen with yeast
- foods made with baking powder
Furthermore, many vegetables, fruits, grains, nuts, and seeds are banned on the diet.
Only foods listed in the guide may be eaten.
The diet limits any food that is processed, animal-based, or made with leavening agents. Certain vegetables, fruits, grains, nuts, and seeds are not allowed.
Here is a three-day sample menu on the Dr. Sebi diet.
- Breakfast: 2 banana-spelt pancakes with agave syrup
- Snack: 1 cup (240 ml) of green juice smoothie made with cucumbers, kale, apples, and ginger
- Lunch: kale salad with tomatoes, onions, avocado, dandelion greens, and chickpeas with olive oil and basil dressing
- Snack: herbal tea with fruit
- Dinner: vegetable and wild-rice stir-fry
- Breakfast: shake made with water, hemp seeds, bananas, and strawberries
- Snack: blueberry muffins made with blueberries, pure coconut milk, agave syrup, sea salt, oil, and teff and spelt flour
- Lunch: homemade pizza using a spelt-flour crust, Brazil-nut cheese, and your choice of vegetables
- Snack: tahini butter on rye bread with sliced red peppers on the side
- Dinner: chickpea burger with tomato, onion, and kale on spelt-flour flatbread
- Breakfast: cooked quinoa with agave syrup, peaches, and pure coconut milk
- Snack: chamomile tea, seeded grapes, and sesame seeds
- Lunch: spelt-pasta salad with chopped vegetables and an olive oil and key lime dressing
- Snack: a smoothie made with mango, banana, and pure coconut milk
- Dinner: hearty vegetable soup using mushrooms, red peppers, zucchini, onions, kale, spices, water, and powdered seaweed
This sample meal plan focuses on the approved ingredients included in the diet's nutritional guide. Meals on this plan emphasize vegetables and fruits with small amounts of the other food groups.
The Bottom Line
The Dr. Sebi diet promotes eating whole, unprocessed, plant-based food.
It may aid weight loss if you do not normally eat this way.
However, it heavily relies on taking the creator's expensive supplements, is very restrictive, lacks certain nutrients, and inaccurately promises to change your body to an alkaline state.
If you're looking to follow a more plant-based eating pattern, many healthy diets are more flexible and sustainable.

When hurricanes and other extreme storms unleash downpours like Tropical Storm Beta has been doing in the South, the floodwater doesn't always stay within the government's flood risk zones.
New research suggests that nearly twice as many properties are at risk from a 100-year flood today than the Federal Emergency Management Agency's flood maps indicate.
Flooding Outside the Zones<p>About <a href="https://furmancenter.org/files/Floodplain_PopulationBrief_12DEC2017.pdf" target="_blank">15 million</a> Americans live in FEMA's current 100-year flood zones. The designation warns them that their properties face a 1% risk of flooding in any given year. They must obtain flood insurance if they want a federally ensured loan – insurance that helps them recover from flooding.</p><p>In Greater Houston, however, <a href="https://doi.org/10.1111/j.1539-6924.2012.01840.x" target="_blank">47% of claims</a> made to FEMA across three decades before Hurricane Harvey were outside of the 100-year flood zones. Harris County, recognizing that FEMA flood maps don't capture the full risk, now <a href="https://www.hcfcd.org/floodinsurance" target="_blank" rel="noopener noreferrer">recommends that every household</a> in Houston and the rest of the county have flood insurance.</p><p>New risk models point to a similar conclusion: Flood risk in these areas outstrips expectations in the current FEMA flood maps.</p><p>One of those models, from the <a href="https://firststreet.org/flood-lab/research/2020-national-flood-risk-assessment-highlights/" target="_blank">First Street Foundation</a>, estimates that the number of properties at risk in a 100-year storm is 1.7 times higher than the FEMA maps suggest. Other <a href="https://doi.org/10.1088/1748-9326/aaac65" target="_blank" rel="noopener noreferrer">researchers</a> find an even higher margin, with 2.6 to 3.1 times more people exposed to serious flooding in a 100-year storm than FEMA estimates.</p>
What FEMA’s Flood Maps Miss<p>Understanding why areas outside the 100-year flood zones are flooding more often than the FEMA maps suggest involves larger social and environmental issues. Three reasons stand out.</p><p>First, some places rely on relatively old FEMA maps that don't account for recent urbanization.</p><p>Urbanization matters because impervious surfaces – think pavement and buildings – are not effective sponges like natural landscapes can be. Moreover, the process for updating floodplain maps is locally variable and can take years to complete. Famously, New York City was updating its maps when Hurricane Sandy hit in 2012 but hadn't finished, meaning flood maps in effect <a href="https://projects.propublica.org/nyc-flood/" target="_blank">were from 1983</a>. FEMA is required to assess whether updates are needed every five years, but the <a href="https://www.fema.gov/cis/nation.html" target="_blank" rel="noopener noreferrer">majority of maps</a> <a href="https://www.oig.dhs.gov/sites/default/files/assets/2017/OIG-17-110-Sep17.pdf" target="_blank" rel="noopener noreferrer">are older</a>.</p><p>Second, binary thinking can lead people to an underaccounting of risk, and that can mean communities fail to take steps that could protect a neighborhood from flooding. The logic goes: if I'm not in the 100-year floodplain, then I'm not at risk. Risk perception <a href="https://doi.org/10.1088/1748-9326/ab195a" target="_blank" rel="noopener noreferrer">research</a> backs this up. FEMA-delineated flood zones are the major factor shaping flood mitigation behaviors.</p><p>Third, the era of climate change scuttles conventional assumptions.</p><p>As the planet warms, extreme storms are becoming <a href="https://nca2018.globalchange.gov/" target="_blank">more common and severe</a>. If greenhouse gas emissions continue to increase at a high rate, computer models suggest that the chances of a severe storm dropping 20 inches of rain on Texas in any given year will increase from about 1% at the end of the last century to 18% at the end of this one, a chance of <a href="https://doi.org/10.1073/pnas.1716222114" target="_blank" rel="noopener noreferrer">once every 5.5 years</a>. So far, <a href="https://www.rstreet.org/wp-content/uploads/2020/02/195.pdf" target="_blank" rel="noopener noreferrer">FEMA hasn't taken into account the impact climate change is having</a> on extreme weather and sea level rise.</p>
Racial Disparities in Flooding Outside the Zones<p>So, who is at risk?</p><p>Years of research and evidence from storms have highlighted social inequalities in areas with a high risk of flooding. But most local governments have less understanding of the social and demographic composition of communities that experience flood impacts outside of flood zones.</p><p>In analyzing the damage from Hurricane Harvey in the Houston area, I found that <a href="https://doi.org/10.1088/1748-9326/aba0fe" target="_blank">Black and Hispanic residents disproportionately experienced flooding</a> in areas beyond FEMA's 100-year flood zones.</p><p>With the majority of flooding from Hurricane Harvey occurring outside of 100-year flood zones, this meant that the overall impact of Harvey was racially unequal too.</p><p>Research into where flooding occurs in Baltimore, Chicago and Phoenix points to some of the potential causes. <a href="https://www.nap.edu/read/25381/chapter/4#16" target="_blank" rel="noopener noreferrer">In Baltimore and Chicago</a>, for example, aging storm and sewer infrastructure, poor construction and insufficient efforts to mitigate flooding are part of the flooding problem in some predominantly Black neighborhoods.</p>
What Can Be Done About It<p>Better accounting for those three reasons could substantively improve risk assessments and help cities prioritize infrastructure improvements and flood mitigation projects in these at-risk neighborhoods.</p><p>For example, First Street Foundation's risk maps account for <a href="https://firststreet.org/flood-lab/research/flood-model-methodology_overview/" target="_blank">climate change</a> and present <a href="https://floodfactor.com/" target="_blank" rel="noopener noreferrer">ratings</a> on a scale from 1 to 10. FEMA, which works with communities to update flood maps, is <a href="https://www.fema.gov/media-library-data/1521054297905-ca85d066dddb84c975b165db653c9049/TMAC_2017_Annual_Report_Final508(v8)_03-12-2018.pdf" target="_blank" rel="noopener noreferrer">exploring rating systems</a>. And the National Academies of Sciences, Engineering and Medicine recently <a href="https://www.nationalacademies.org/news/2019/03/new-report-calls-for-different-approaches-to-predict-and-understand-urban-flooding" target="_blank" rel="noopener noreferrer">called for a new generation of flood maps</a> that takes climate change into account.</p><p>Including recent urbanization in those assessments will matter too, especially in fast-growing cities like Houston, where <a href="https://authors.elsevier.com/a/1boBRyDvMFW6W" target="_blank" rel="noopener noreferrer">386 new square miles</a> of impervious surfaces were created in the last 20 years. That's greater than the land area of New York City. New construction in one area can also <a href="https://scalawagmagazine.org/2018/01/city-in-a-swamp-as-houston-booms-its-flood-problems-are-only-getting-worse/" target="_blank" rel="noopener noreferrer">impact older neighborhoods downhill</a> during a flood, as some Houston communities discovered in Hurricane Harvey.</p><p>Improving risk assessments is needed not just to better prepare communities for major flood events, but also to prevent racial inequalities – in housing and beyond – from <a href="https://www.npr.org/2019/03/05/688786177/how-federal-disaster-money-favors-the-rich" target="_blank" rel="noopener noreferrer">growing</a> after the unequal impacts of disasters.</p>
