3 Takeaways from Dr. Dharma Singh Khalsa’s Brain Longevity Diet
From the Dr. Dharma team · David Coryat

If you want to care for your memory and keep your mind sharp as you age, you’re in the right place. Dr. Dharma Singh Khalsa, a physician, has spent his career helping people care for their brains. His book, Brain Longevity, is a plain approach to caring for the mind, and one of its longest sections is about food. In this post, we look at three principles from Dr. Dharma’s Brain Longevity Diet.
His philosophy is clear
“A rigid, denial-based diet cedes all power and control to whoever created the diet. I don’t believe in that at all. I don’t want to control my patients. I want them to learn self-control, the only kind of control that ever really works, and the only kind that lasts.”
Dharma Singh Khalsa, M.D., Brain Longevity, 1997
With the right knowledge, you can make informed decisions about your health, giving you more control over your well-being.
Instead of simply labeling foods as “good” or “bad,” Dr. Dharma guides us through a series of dietary principles designed to support brain health. Here are three takeaways:
1. Eat a Balanced, Low-Fat Diet
A healthy heart equals a healthy brain. Good circulation is critical for both heart and brain health. As he writes in Brain Longevity (1997), it is good to “clean your blood” in order to “clear your head.”
Cerebral circulation is key for brain function. It delivers oxygen, glucose, and micronutrients to neurons, aids in cleaning up cellular debris, and helps protect brain cells from oxidative stress caused by free radicals. Excessive fat intake can impair circulation, reducing the brain’s access to these essential nutrients.
Saturated fats, found in foods like fatty meats, butter, and cheese, can thicken the blood and don’t dissolve well in the bloodstream. Unsaturated fats, like those in avocados, olive oil, and fatty fish, are the better choice for brain health.
Dr. Dharma suggests limiting fat intake to 15-20% of daily calories, focusing on monounsaturated fats, such as olive oil, nuts, and flaxseed oil. You still need some fat for brain and body function, but keeping it modest gives your brain its best chance as you age.
2. Avoid Low Blood Sugar
Is your brain running on empty? Low blood sugar can leave your brain without the energy it needs. It can cause dizziness, irritability, brain fog, and difficulty focusing or remembering.
Dips can come from skipping meals or eating too much sugar, which triggers a surge of insulin followed by a crash. To avoid them, Dr. Dharma recommends a balanced diet full of complex carbohydrates and protein.
Foods like soy help keep energy steady. For those interested in intermittent fasting, talk with your doctor first, since fasting can lead to low blood sugar. A simple habit: eat your last meal at least 3-4 hours before bed.
3. Take Supplements
A good diet is foundational. But modern agriculture and fast-paced lifestyles often mean Dr. Dharma adds supplements to his, and here is what he takes.
He takes a multivitamin (his is Gold Multi-Vitamin), CoQ10 and resveratrol (both in Super Rejuvenation), ginkgo biloba (in Brain Caps) and milk thistle (in Inner Healing). Always consult your doctor before starting any new supplement, especially if you take medication or have a health condition.

Taking the right steps toward brain longevity doesn’t require drastic measures. It’s about informed choices. When you combine a balanced diet, mindful supplementation, and simple lifestyle adjustments, you are giving your brain a fair chance.
