New Autism Research & Brain BreakthroughNov 26, 2025Your brain responds to every meal, every night of sleep and every walk you take. Dr. Colbert shares the latest research on focus, mood and memory, and practical ways to care for the mind God gave you.
Simple ways to protect your memory
Memory loss is not an automatic part of aging. Research points to a handful of habits that help keep the brain sharp for decades.
- Feed your brain. Omega-3 rich fish, leafy greens, berries and olive oil appear again and again in brain research, as in this Mediterranean diet study.
- Guard your sleep. Deep sleep is when the brain clears waste and stores memories.
- Keep moving. Regular exercise increases blood flow to the brain and supports mood.
- Watch your gut. The gut and brain talk constantly. Read why brain fog can start in the gut.
- Renew your mind. Gratitude, prayer and calming chronic stress all support a healthier brain.
Start with these guides: the best habits for brain health, a brain-healthy diet to help lower Alzheimer’s risk, what studies say about magnesium and memory and why your homocysteine number matters for your brain.
For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind. (2 Timothy 1:7, KJV)
