If you recently had your A1c measured and it was a 5.7 or higher, you may be searching for ways to lower it naturally. Your A1c is a measure of your average blood sugar levels over the past 3 months. This number gives healthcare professionals a good idea about how your blood glucose levels are trending over time. Tips to lower A1c include diet modifications because what you eat and how you eat greatly impact your blood sugars. When considering diet modifications, I strongly recommend a plant-based or plant-forward eating style for lowering A1c quickly.
Why should I eat plants to lower A1C?
Plants are:
High in fiber – slows down how fast sugar enters the blood
Low in unhealthy fats – helps insulin work better
Full of vitamins and antioxidants – lowers swelling in the body
Good for gut health – helps control blood sugar signals
You do not have to be fully vegan. Most people do well with a plant-forward diet, meaning plants make up most of the plate.
Using the Plate Method To Manage Blood Sugars
Try to build meals like this:
- ½ plate non-starchy vegetables
- ¼ plate plant protein
- ¼ plate whole grains or starchy vegetables
- A small amount of healthy fat
This balance helps keep blood sugar steady after meals. After 3 months, many people notice:
- Lower fasting blood sugar
- Fewer sugar spikes after meals
- Lower A1C
- More energy
Small daily changes really add up.

- Bean and veggie chili

Foods to Limit for Better A1C
Try to cut back on:
- Sugary drinks and sweet tea

- White bread and pastries
- Large portions of fried foods
Focus on adding more plants first, not strict dieting.
Lowering A1C does not mean giving up flavor or culture. A plant-based, fiber-rich way of eating can help African Americans manage blood sugar while feeding the whole family.
Every plant-rich meal helps. Progress matters more than perfection.
