Eating healthy and protecting your body from processed chemicals has been the goal of many people for the past few years. As more and more people are becoming aware of how junk and processed foods affect our health, they are changing their diet and making healthier choices. However, a point of concern for many people lies in their age. Does it make a difference, changing your diet later in life? You can start protecting your brain health through your diet at any point in life, according to a new study. People who improved their healthy eating habits in middle age saw a 25% lower risk of developing dementia, compared to those whose diets got worse over time. These exciting findings were shared at a recent meeting of the American Society for Nutrition (ASN). Researchers stated that the study's results confirm that healthy eating patterns in mid to late life, and improving those patterns over time, can help prevent Alzheimer's and related forms of dementia. This clearly suggests that it's truly never too late to adopt a healthy diet as a way to guard against dementia. How the Study Was Conducted For this important study, researchers looked at information from almost 93,000 adults who were part of a long-term health study. These people were between 45 and 75 years old when the study began in the 1990s. Over the years, more than 21,000 of them developed Alzheimer's disease or other forms of dementia. Everyone in the study filled out food questionnaires, which helped researchers see how closely they followed the MIND diet. The MIND diet is a special eating plan that combines the best parts of two other healthy diets: the Mediterranean diet and the DASH diet (which helps lower blood pressure). Both of these diets are known to make people healthier. According to the Harvard T.H. Chan School of Public Health, the MIND diet focuses on eating more whole grains, vegetables, nuts, beans, berries, chicken, and fish. It also suggests eating less pastries, sweets, red meat, cheese, fried foods, and butter. Significant Drop In Risk And Visible Changes The study found that people who followed the MIND diet from the start had a 9% lower chance of getting dementia. Even better, there was a 13% bigger drop in risk for Black, Hispanic, and white people. The researcher noted that healthy eating helped these groups more, but it wasn't as clear for Asian Americans and Native Hawaiians. This suggests that advice about diet might need to be different for different groups of people. Perhaps the most encouraging discovery was that people whose diets got closer to the MIND diet over 10 years had a huge 25% lower chance of getting dementia. This was true even if they didn't follow the diet perfectly at first. This really shows that making positive changes to your diet later in life can still have a big positive impact on your brain health. Healthier Food Choices For Brain Health Just like there's no magic pill for a sharp mind, no single food will keep your brain perfect as you age. Harvard Health Publishing says the best approach is to eat a generally healthy diet. This means focusing on lots of fruits, vegetables, beans, and whole grains for overall brain health. Green, Leafy Vegetables Leafy greens like kale, spinach, and broccoli are packed with nutrients vital for your brain, such as vitamin K and folate. Studies suggest eating these greens can help slow down memory loss and keep your thinking sharp as you get older. Fatty Fish Fish like salmon and cod are full of omega-3 fats, which are healthy fats linked to lower levels of a protein that harms brains with Alzheimer's. Aim to eat fish at least twice a week, choosing options low in mercury like light tuna. Berries The bright colors in berries come from plant parts called flavonoids, which research shows can also improve memory. Eating berries like strawberries and blueberries regularly may help delay memory problems by a few years. Tea and Coffee The caffeine in your daily tea or coffee might do more than just wake you up. Studies suggest that people who consume more caffeine often score better on memory and thinking tests, and it might even help you remember new things. Walnuts Walnuts are a great source of protein and healthy fats. Studies link eating walnuts to better scores on memory and thinking tests. They contain a special omega-3 fat that helps keep your blood pressure down and arteries clean, benefiting both your heart and brain.
