Carbohydrates are a primary source of energy for the brain, playing a crucial role in cognitive function, focus, and memory. However, not all carbs are created equal. While complex carbohydrates from whole foods provide sustained energy and support brain health, refined and highly processed carbs can have the opposite effect. These unhealthy carbs cause rapid spikes and crashes in blood sugar levels, leading to brain fog, sluggish thinking, and memory issues.

Over time, excessive consumption of these foods may contribute to inflammation and insulin resistance, both of which are linked to cognitive decline.

According to dietitian Krutika Nanavati, the carbs you should avoid are sugary cereals and pastries. Read on to learn more.

1. Sugary Cereals

Sugary cereals are a popular breakfast choice, but they are often loaded with refined carbohydrates and added sugar. All that sugar can take a toll on your health. Nanavati explains, "This can cause blood sugar spikes and crashes, leading to brain fog and difficulty concentrating." The rapid fluctuations in blood sugar levels can make it hard for your brain to maintain steady energy, resulting in impaired cognitive function. Over time, consuming high-sugar breakfasts can lead to insulin resistance, which further exacerbates brain health issues.

2. Pastries and Donuts

Pastries and donuts are breakfast staples that are high in sugar and unhealthy fats. According to Nanavati, "This can impair cognitive function and contribute to memory problems." The combination of sugar and trans fats in these foods can cause inflammation and oxidative stress, which can negatively impact brain health and lead to issues with memory and focus. Additionally, the high-calorie content with little nutritional value means these foods can contribute to weight gain and associated metabolic disorders, further affecting brain function.
