Avocados help slow the progression of Alzheimer's disease and also improve oxygen supply to the brain.

While their benefits for heart health and diabetes are well-documented, recent research shows that they are just as good for maintaining cognitive functions or your ability to process thoughts, memory, improving focus and potentially warding off neurological decline.
Avocados are rich in monounsaturated fats or healthy fats that ensure blood flow and an adequate supply of oxygen and nutrients to the brain. They sharpen cognitive abilities and prevent mental fatigue. Studies have shown that diets high in monounsaturated fats can enhance memory as we age.
Another brain-friendly nutrient in avocados is lutein, a carotenoid that accumulates in the brain. Lutein is known to improve cognitive performance, including processing speed and memory. In older adults, higher levels of lutein have been linked to mental sharpness and a slower rate of cognitive decline. What sets avocados apart is their ability to deliver lutein effectively by making it easier for the body to absorb and use them.
The fruit also contains folate, a B-vitamin that helps produce neurotransmitters like serotonin and dopamine, which regulate moods and emotional well-being. A deficiency in folate has been associated with an increased risk of depression and other mood disorders.
Chronic inflammation and oxidative stress (when free radicals damage cells) are two major contributors to brain ageing and diseases like Alzheimer’s. Avocados are packed with antioxidants, including vitamin E and vitamin C, which combat free radicals in the brain. Vitamin E, in particular, has been studied for its potential to slow the progression of Alzheimer’s disease. These antioxidants synergise themselves to protect neurons. Avocados contain potassium, which balances electrolyte levels in the body and is crucial for nerve functioning and cutting brain fog.
Avocados are a natural source of magnesium, a mineral crucial for mood regulation. Low levels of magnesium are often linked to anxiety and depression. Furthermore, the combination of healthy fats and dietary fibre in avocados provides a steady release of energy, keeping you focussed throughout the day.
Adding avocados to your daily meals is simple and versatile. Blend them into smoothies, mash them onto whole-grain toast, or dice them into salads. Turn them into a creamy guacamole or use as a butter substitute while baking. Pairing avocados with other brain-boosting foods like leafy greens and nuts can amplify their benefits.
It is healthy fat, but it’s still fat. Don’t overdo it. Half of a whole fruit is 120 calories, a third, 80 calories and a few thin slices, 65 calories. Choose what works for you.
