The consumption of some foods, for weeks or months, causes a lower glycemic response; however, it is not known how the addition of them (in a single dose) to meal changes postprandial glycemia. OBJECTIVES: To analyze the acute glycemic response and palatability in men with type 2 diabetes after consuming a standard meal with the addition of different foods. METHODS: A randomized, crossover clinical trial was conducted with 19 men with type 2 diabetes (DT2) (<60 years). Each volunteer ate a standard meal in the morning on 13 occasions, separated by a period of three to ten days. On 12 occasions, a different food was eaten immediately before the standard meal: cinnamon, wheat bran, chia flour, flaxseed flour, avocado, lettuce, tomato, or olive oil. Blood glucose was monitored for 120 minutes and palatability was estimated at 15 minutes after eating the meal. RESULTS: There was a decrease in the glycemic area under the curve, compared to the standard meal, after breakfast with 3 or 6 g of cinnamon in capsules; 3 or 6 g of cinnamon powder; 15 g of wheat bran; 15 g of chia flour; 15 g of golden flaxseed flour; 100 g of lettuce; 30 ml of extra virgin olive oil; 115 g of salad consisting of 50 g of lettuce, 50 g of tomatoes and 15 ml of extra virgin olive oil, or 100 g of avocado. There was a decline in glycemic peak after breakfast with 3 or 6g of cinnamon powder; 6 g of cinnamon in capsules; 15 g of chia flour; 30 ml of extra virgin olive oil; 115 g of wrong salad, or 100 g of avocado, compared to the standard meal. Regarding palatability, there was no difference between the tested meals. CONCLUSION: The present thesis showed that the addition of cinnamon, wheat bran, chia flour, flaxseed flour, avocado, lettuce, or olive oil to a balanced breakfast decreases the postprandial blood glucose response in men with type 2 diabetes
