Food Is Medicine—And Science Is Catching Up
In an age of over-supplementation, sometimes the most powerful medicine is already sitting in your fruit bowl.
In Chinese medicine, food and herbal medicine are never separate. They exist on a continuum. They’re different expressions of the same thing: Nourishment and health
What could be better than a sweet treat that’s therapeutic?
Let’s talk about three simple, sweet fruits that are healing: prunes for bone health, dates for labor, and pineapple for inflammation and recovery.
🦴 Prunes for Stronger Bones
Here’s some research that recently grabbed my attention. Turns out that prunes help more that only digestion; They are one of the most researched foods for preventing bone loss, especially in postmenopausal women. The research is surprisingly solid:
- Women who ate 5–6 prunes daily (≈50 g) for a year preserved hip bone density compared to controls【pubmed.ncbi.nlm.nih.gov/35798020】.
- Another 12-month study found prunes maintained tibial bone structure and strength【pubmed.ncbi.nlm.nih.gov/38349471】.
- Reviews conclude that prunes reduce inflammation and oxidative stress—key factors in bone breakdown【pubmed.ncbi.nlm.nih.gov/34978320】
Why and how it works:
First: It’s important to clarify that prunes don’t increase bone density. That’s accomplished by lifting weights. But preserving bone density with a food
A cornerstone of Western nutrition advice for bone health is the consumption of calcium rich foods. See Cara’s Personal Bone Building Plan.
Bone matrix is influenced by numerous nutrients. Prunes are rich in polyphenols, vitamin K,magnesium, and potassium—nutrients essential for bone metabolism. They calm inflammation, support osteoblast activity, and slow bone resorption. Osteoblasts are cells that build bone tissue. Osteoclasts break down bone matrix.
In East Asian theory, the connection makes perfect sense: their dark, sweet, moist nature resonates with the Kidney system, which are said to governs the bones.
How to use them:
It’s recommended to 5–6 prunes daily. This is approximately 50 gas, which is slightly less than two ounces. Eat them plain. Soak them overnight, blend into a smoothie, or pair with yogurt. In the studies, the comparison group that ate 100 gms of prunes mostly dropped out. Presumably they got diarrhea.
Caution:
They’re sweet—so if you’re managing blood sugar, adjust your portion. Also Remember to brush and floss after! They are sticky and can cause cavities.
🤰 Dates: The Ancient Midwife’s Knowledge
Dates have been used in traditional medicine for centuries to prepare women for childbirth. Research agrees however it seems nuanced. I found a couple of studies on the topic:
- Women who ate 6 dates daily in the last 4 weeks of pregnancy were less likely to need induction or augmentation【pubmed.ncbi.nlm.nih.gov/21280989】
- A meta-analysis found better cervical ripening and shorter labors overall【bmcpregnancychildbirth.biomedcentral.com/articles/10.1186/s12884-023-06196-y】.
What’s happening:
Dates may boost prostaglandin activity, helping soften the cervix naturally. They’re rich in iron, potassium, and fiber
The dates we use in herbal medicine are not the sweet dates you’re used to eating. Ours, Da Zao are smaller, red and somewhat starchy jujube. They are sweet and warm, and nourish Qi and Blood. We also use a black date called Hei Zao. It’s the same fruit, but processed differently.
How to use:
4–6 Medjool dates daily starting around week 36.
Caution:
If you have gestational diabetes, tt would be prudent to limit them. Dates, even though it’s a natural sweet, have a high glycemic index, meaning they can increase blood sugar. Even if They support labor progression but won’t “flip the switch.”

🍍 Pineapple and Bromelain: Cooling Heat and Calming Inflammation
Pineapple’s super power lies in bromelain, a group of enzymes concentrated in the fruit’s core. It’s well-studied for its anti-inflammatory, digestive, and recovery benefits. There’s a lot of data on them. Here’s a few highlights:
- Pineapple reduces pain and swelling after surgery or injury【pmc.ncbi.nlm.nih.gov/articles/PMC4998156】At Six Fishes, we use a well researched bromelain product, Wobynzym for patients after surgery to reduce scarring.
- Helps mild arthritis symptoms by lowering inflammatory cytokines【pmc.ncbi.nlm.nih.gov/articles/PMC538506】.
- Aids digestion by breaking down proteins.
From a Chinese medicine perspective, pineapple’s slightly cooling, moving quality helps clear heat and resolve stasis, making it perfect for muscle and joint pain, or post-injury recovery.
How to use:
Eat one cup of fresh pineapple (include a little of the core if tolerated).
Caution:
Ignore the labor-induction myth—there’s no reliable evidence for that. The amount of bromelain in pineapple is too small to be clinically meaningful【verywellfamily.com/does-pineapple-induce-labor-experts-weigh-in-7254572】.
Also, bromelain supplements can interact with blood thinners or antibiotics—stick to food doses unless advised otherwise.

🌿 Bringing It All Together
I love therapies that are simple, affordable, and accessible. Three fruits. Three distinct healing actions:
- Prunes: Strengthen bones and nourish Kidney essence.
- Dates: Support late pregnancy and labor readiness.
- Pineapple: Calm inflammation and promote recovery.

Chicken Marbella from the Silver Palate Cookbook
I’m really dating myself with this recipe but in the early 80’s this was the dish. The classic Chicken Marbella recipe was a cult favorite from The Silver Palate Cookbook (1982). It’s savory, tangy, sweet, and ridiculously easy to make ahead. It tastes better the next day. And, in keeping on topic, it contains prunes. Here’s the original, from the NY Times.
I’m sharing a somewhat more heart-healthy version, with less fat and less sugar
Ingredients
- 4 bone-in, skin-on chicken thighs (remove skin after baking if desired)
- 4 cloves garlic, minced
- 2 tsp dried oregano
- ½ tsp sea salt
- ¼ tsp freshly ground black pepper
- 3 Tbsp red wine vinegar
- 3 Tbsp extra-virgin olive oil
- ½ cup pitted prunes, halved
- ⅓ cup pitted green olives (Castelvetrano or manzanilla)
- 2 Tbsp capers + 1 tsp caper brine
- 2 bay leaves
- ½ cup dry white wine
- 1 Tbsp honey (instead of ½ cup brown sugar)
- 2 Tbsp chopped fresh parsley
Instructions
- Marinate
In a large glass bowl, combine garlic, oregano, salt, pepper, vinegar, olive oil, prunes, olives, capers, brine, and bay leaves.
Add the chicken and turn to coat well.
Cover and refrigerate 4–8 hours (overnight is ideal). Stir once or twice. - Roast
Preheat oven to 375°F (190°C).
Arrange chicken and all marinade in a single layer in a baking dish.
Drizzle the honey evenly over the top and pour wine around (not over) the chicken. - Bake
Roast for 45–50 minutes, basting once halfway through.
Chicken is done when juices run clear and internal temp hits 165°F (74°C). - Serve
Transfer chicken to a platter and top with the olives, prunes, and capers from the pan.
Spoon a little pan juice over and sprinkle with parsley.
Make it healthier:
- Remove the skin before serving to reduce saturated fat.
- Add fiber: serve over farro, barley, or quinoa instead of rice.
- Add greens: pair with a side of garlic sautéed spinach or roasted broccoli.
- Use less salt: the olives and capers are plenty salty.
