I'm eating Purple Sweet Potatoes. Why are purple foods so magical for statistically helping to reduce the risk of disease.?
A few days ago, I listened to a podcast episode of Mel Robbins featuring Dr. Dawn Mussallem — and I honestly haven’t stopped thinking about it since. If you like podcasts, Mel Robbins has incredible podcasts and I learn so much.
Dr. Mussallem is both a cancer survivor and a respected oncologist at the Mayo Clinic, and throughout the interview she shared medical statistic after statistic about how we need to eat foods that protect our bodies from disease… and eliminate or reduce foods that potentially increase disease risk over time.
Shocking Statistics
The podcast was fascinating, educational, and honestly a little shocking. Dr. Mussallem shared facts that were hard to ignore. She explained that studies now suggest that the foods we eat every single day may either help lower our risk of getting cancer… or quietly increase our risk of getting cancer it over time
Foods That may help lower the risk of developing cancer :
1. Berries especially blueberries (which can be purchased frozen)
Rich in antioxidants that help protect cells from damage and inflammation.
2. Purple Sweet Potatoes
Loaded with anthocyanins — the same powerful antioxidants found in blueberries and purple cabbage that give these foods their deep purple color.
3. Soy Foods — Especially Edamame
Dr. Mussallem explained that minimally processed soy foods are actually linked to protective benefits, despite years of confusion and misinformation surrounding soy.
4. Cruciferous Vegetables - a daily must
Broccoli, cauliflower, cabbage, arugula, Brussels sprouts, and similar vegetables contain compounds associated with cancer protection.
5. Kiwi
Very helpful for digestion and elimination so toxins and waste do not sit in the body as long.
6. Beans and Lentils
Dr. Mussallem stressed the vital importance of a high fiber diet. Beans and lentils provide vital fiber, antioxidants, and plant protein that help support gut and metabolic health and proper elimination of waste in the body.
7. Leafy Greens- generous amounts
Spinach, kale, romaine, sprouts, arugula and other greens are loaded with nutrients and protective plant compounds.
Watch Out For Bad Foods That May Turn On Disease Promoting Pathways
Dr. Mussallem explained that many foods may actually help “turn on” inflammation and disease-promoting pathways in the body. That is honestly hard to ignore.
Avoid or Eliminate- these foods may increase the risk of cancer
1. Processed Meats
Lunch meats, bacon, sausage, hot dogs, and many processed chicken products. Lox and cured fish are classified as processed meats as well.
2. Ultra-Processed Foods
Packaged foods made in factories that contain preservatives, artificial ingredients, food dyes, carrageenan, mono and diglycerides, and other destructive chemical additives.
3. Artificial Sweeteners
This was another major warning. Many sugar-free products contain artificial sweeteners or sugar alcohols such as sucralose, erythritol, aspartame, and others. Emerging research continues to raise concerns about how these additives may negatively affect gut bacteria, insulin response, inflammation, cravings, and overall metabolic health.
I use stevia packets all the time.- sure enough, I checked the package and the first ingredient was erythritol- GEEZ !!! Who Knew??? I just purchased pure stevia online. (why is erythritol scary? scroll down to read under my notes.

My Notes:
Some of the statistics she shared were startling:
- Ultra-processed foods now make up roughly 63% of the average American diet.
- Diets high in refined grains, ultra-processed foods, and added sugars may increase breast cancer risk by approximately 20%.
- Women with the highest levels of insulin resistance were found to have a 34–78% higher breast cancer risk.
- Processed meats such as bacon, sausage, hot dogs, and deli meats are classified as Group 1 carcinogens — the same category as smoking and asbestos. Meaning there is enough convincing scientific evidence proving processed meats may cause cancer in humans.
Erythritol: The major concern from erythritol is blood clotting
Several studies from researchers at the Cleveland Clinic found that erythritol may make platelets more “sticky,” increasing clot formation potential. In studies, people consuming a typical serving had erythritol blood levels rise dramatically, along with increased platelet activity.
Researchers warned this could raise the risk of:
- Stroke
- Heart attack
- Blood clots
**: erythritol is often hidden inside products labeled “stevia” or “monk fruit.” The front label may highlight the natural sweetener, but erythritol is often the first ingredient in the ingredient list. I had no idea-


Very interesting. I try to make sure we eat a 'rainbow' of fruit and vegetables regularly.
ReplyDeleteThat makes sense...
DeleteI enjoy purple sweet potatoes, but in my area they're harder to find and substantially more expensive.
ReplyDeleteThey are expensive
DeleteI plan on getting one from the market and sprouting some starts, I hope to grow them!
ReplyDeleteyes, I read sweet potatoes are easy to grow.
DeleteI used purple sweet potatoes once in a while because it's pretty.
ReplyDeleteYes, they do look nice and pretty and good for you too.
DeleteI read up on this some years back and followed the suggestions. Several years ago I had a medical problem which required major surgery. My diet has been slightly off since then and I need to re-organize it. Thanks for sharing!
ReplyDeleteI go on tangents - I start a regime and then get off track.
DeleteIt is a bit worrying that products marked as sugar free actually contain artificial sweeteners. These have their own negative impacts.
ReplyDeleteI agree. I have been buying stevia for a year now and had no idea it was mixed with artificial sweetener.
DeleteI have never seen purple sweet potatoes but I would definitely eat them if I did. I used to LOVE the purple Puruvian potatoes when we could find them locally but I don't think I've seen those in 15 or so years.
ReplyDeleteThe purple sweet potato is called a stokes sweet potato. They can be expensive
DeleteI've never seen purple sweet potatoes before. I've read about many of these foods, and I eat broccoli often. I need to lighten up the sugar, as sweets are my weakness. I knew about blueberries and just had them in my cereal. I've heard that aspartame is so bad for us, and I stay away from artificial sweeteners. Thank you for this post filled with good information. : )
ReplyDeleteSweets are my weakness too.
DeleteExcellent tips. Other than the purple sweet potato I already try to incorporate all of these into our weekly meals.
ReplyDeleteI try too but sometimes we start to eat out to much and start to eat processed foods again.
DeleteI prepare baked sweet potatoes in batches and serve these every night. I also use frozen blueberries in my oatmeal every morning and in my smoothie at lunch. But the wonderful benefits of the purple sweet potato are definitely something I need to consider. They certainly would be a delicious way to help me improve my weekly mix of fruits and veggies!
ReplyDeleteWow Heidi- sounds like you have your bases covered
DeleteWhat we eat is so important for gut health. To me, ultra processed foods are to be left on the shelf! We eat cured meat and fish, but in moderation. I think that's a key note as well.
ReplyDeleteThat's what she said- eat less of the more inflammatory foods.
DeleteInteresting post and information. I have never tried the purple sweet potato.
ReplyDeleteTake care, Happy Tuesday! Enjoy your day!
purple sweet potato is excellent but so is purple cabbage, purple grapes, and blueberries. Eat the rainbow for color
DeleteIt’s always good to get advice from reliable sources. We eat sweet potatoes regularly although I have never specifically sought the purple ones. I will keep an eye open when I shop for vegetables later today. I eat blueberries almost every day, too.
ReplyDeleteIt sounds like you are eating a lot of health giving foods
DeleteI love purple sweet potatoes more than orange. My grandparents always grew Japanese sweet potatoes, and I can still find them around here most of the time. We talk all of the time abut eating the rainbow.
ReplyDeleteI have never tried to grow sweet potatoes but I understand it is very easy
DeleteOh this is a wonderful post. I will look this podcast up. I can't find purple sweet potatoes here. We eat red garnet sweet potatoes several times a week. Thank you for this post.
ReplyDeleteThank you
DeleteTotally with you on the sweeteners, they are so very bad for you. I avoid them like the plague and am lucky I don't have a sweet tooth either thankfully! I swear by garlic, I eat a raw clove everyday.
ReplyDeleteI was also reading about the countless benefits of tofu and miso. I am so glad I love tofu in every shape or form haha! And love a good tofu miso soup too :-D
I never used to use them and then about a year ago I wanted to loose weight so I started using stevia = who knew it was mixed with even worse ones.
Deletei have eaten these purple sweet potatoes. not because i "knew" they were good for me, just because i like them. i also love the colored fingerling potatoes...if you read my "about me" on my blog, i talk about my obsession with potatoes!!
ReplyDeleteI never ate them and they are sometimes difficult to find But now I'm eating them
DeleteGreat post Judee ... eat the colours of the rainbow :)
ReplyDeleteAll the best Jan
Thanks Jan..
DeleteVery interesting!
ReplyDeleteAround here, I like to think of dragon fruit as part of my “rainbow plate” 🌈
Its bright pink skin and speckled white flesh are packed with antioxidants too.
I think fruit of any kind is part of a health promoting diet.
ReplyDeleteI'm also into purple sweet potatoes and am trying to grow some in the garden. I also listen to the Mel podcast and can recommend the Zoe podcast, I've learned so much from them.
ReplyDeleteAmalia
xo
Wow that would be great to grow them in the garden. I'll check out Zoe - thanks.
DeleteThanks for this interesting post with this useful information. I had no idea about the benefits of sweet potatoe.
ReplyDeleteYour book looks interesting. Good luck with the sales.
DeleteWe need to get back to eating whole foods. We're seeing an alarming rate of younger people getting diagnosed with colon cancer, which used to be considered an "old man disease". They can't figure out why the increase. I'm betting it has to do with all of the processed offerings that's really been on the rise since the 80's. I do like Mel's podcast. She really gets me thinking after tuning in.
ReplyDeleteIt's all very scary and we are not educated on how our food supply is changing and the consequences. How would a young person know any differently.
DeleteInteresting read, especially the way you connected what you heard on the podcast with everyday food choices. Colorful whole foods like berries, beans, and purple sweet potatoes have long been part of traditional diets for a reason, especially when it comes to fiber and plant compounds. The part about ultra-processed foods and reading labels closely feels particularly relevant, since so much gets hidden in plain sight these days. It also raises a bigger question about how modern convenience foods have shifted what many people now consider a normal diet.
ReplyDeleteYes, we can't take for granted that the food in the markets is healthy. Gotta read labels
DeleteI can’t have soy, and I’m not a fan of sweet potatoes, but I can totally get on board with everything else. Cruciferous vegetables are particular favorites, and I am never without them. I also love radishes, if you can believe that. I think I have those every day. I find it disturbing all of the things that are being sprayed on the food that we eat, so every year I grow more and more. This year I have added celery to my little deck garden. I’m looking forward to trying homegrown celery.
ReplyDeleteI actually like the purple better than the orange ones. I agree the way our food is being sprayed and many times we are not even aware. It's scary- even organic can be sprayed.
DeleteI've never seen purple sweet potatoes before, but I'm gonna keep my eye out for them now. And I'm also checking my stevia package!
