These onions are perfect for frilling, pickling, or garnishing a salad. Lastly, white onions are a crunchy variety with a less pungent aftertaste than some of their counterparts. These onions are commonly
found in Mexican cuisine (i. e. salsa, guacamole, or tacos), but are also commonly used in barbeque. Benefits of OnionsBesides providing a delicious flavor, onions actually pack multiple health benefits. Onions contain micronutrients such as vitamin B, vitamin C, and potassium. They are all packed full of
antioxidants that may help reduce inflammation and lower the risk of cardiovascular disease and cancer. [1]Onions are rich in the antioxidant quercetin, which has been shown to improve blood pressure levels in clinical trials. [2] Additionally, research has shown that the consumption of raw onions may help individuals with PCOS lower cholesterol levels. [3]White and red onionsOnion Nutrition FactsThere are many different varieties of onions but for these purposes, we will be breaking down the nutrition facts of the three most common onion varieties: sweet onions, yellow onions, white onions, and red onions.
It fuels the work that cells need to do. While glucose is a simple sugar, it is still a relatively large molecule, therefore it needs certain transporters in order to allow it to enter a cell. These are known as GLUTs (glucose transporters). [2] Contrary to popular belief, not all cells require insulin in order to transport glucose inside of a cell. Some organs and tissues are insulin-independent, meaning insulin is not required, whereas others are insulin-dependent, meaning they require insulin. [3] GLUT 4 transporters are located on skeletal muscle, adipose tissue, and the heart and do require insulin. In order for glucose to be transported into these cells, insulin must bind to insulin receptors and signal for this process to occur. Insulin is produced by beta cells in the pancreas in response to high blood glucose levels. Once it is released, it binds to insulin receptors and triggers a response to allow glucose to be transported into the cell.

If insulin is not produced sufficiently, glucose is unable to enter insulin-dependent cells and these cells can starve.
