Is Dark Chocolate Anti-Inflammatory? What Research Shows

by Mo Mandegar, PhD on Jul 18 2026
Dark chocolate keeps showing up on anti-inflammatory food lists, and it is not wishful thinking. Cocoa is one of the most polyphenol-dense foods there is, and recent trials link its flavanols to lower inflammatory markers, with high-sensitivity C-reactive protein falling about 8.4% a year on a daily cocoa flavanol dose. Here is what the research shows and how much to eat.

Is Dark Chocolate Good for Your Skin?

by Mo Mandegar, PhD on Jun 29 2026
"Eat dark chocolate for glowing skin" is part true and part wishful. Real randomized trials found that about 320 milligrams of cocoa flavanols a day improved skin elasticity and cut ultraviolet (UV) induced redness by roughly 25 percent over 12 weeks. The catch is dose: a single square delivers far less. Here is what the research actually shows, and how chocolate fits into skin health.

Dark Chocolate and Brain Function: The Flavanol Link

by Mo Mandegar, PhD on Jun 22 2026
Cocoa flavanols connect dark chocolate to brain function by raising cerebral blood flow to the hippocampus. In a 2023 trial, 500 milligrams of cocoa flavanols a day improved memory in older adults who ate few flavanols to begin with. The catch: those flavanols survive only in minimally processed, high-cacao chocolate. Here is the mechanism, what the research shows, and how to choose a bar that still has flavanols left in it.

Can You Eat Dark Chocolate Every Day? A Practical Guide

by Mo Mandegar, PhD on May 17 2026
Can you eat dark chocolate every day? Recent research from Harvard, the COSMOS trial, and the European Food Safety Authority (EFSA) points to a clear daily-habit recipe: 20 to 30 grams of 60 to 80 percent cacao, eaten consistently rather than in big servings. Here is the dose-response data, the flavanol math, and how the daily evening square compares to its competitors for the same slot.

How Much Dark Chocolate Do You Need for Flavanols?

by Mo Mandegar, PhD on May 11 2026
The 2023 Food and Drug Administration (FDA) qualified health claim for cocoa flavanols set a daily target of 200 milligrams. Translated into chocolate, the answer depends almost entirely on how the cocoa was processed: 1 to 2 ounces of premium non-alkalized dark chocolate gets you there from food alone; heavily Dutch-processed bars cannot.
