Nutritional Profile of Onion :-

Onion is low in calories but high in vitamins, minerals, and fiber. According to the USDA, one medium onion (110 grams) provides the following nutrients:

- Calories: 44
- Protein: 1.2 grams
- Carbs: 10.3 grams
- Sugar: 4.7 grams
- Fiber: 1.9 grams
- Fat: 0.1 grams
- Potassium: 3.4% of the Daily Value (DV)
- Vitamin C: 9% of the DV
- Vitamin B6: 5% of the DV
- Folate: 5% of the DV

Onion is especially rich in vitamin C, which is a powerful antioxidant that helps boost your immune system, support collagen production, and enhance iron absorption. It also contains B vitamins, such as folate and vitamin B6, which are essential for metabolism, red blood cell production, and nerve function.
Onion is also a good source of potassium, a mineral that plays a key role in regulating fluid balance, nerve transmission, muscle contraction, and kidney function. Many people do not get enough potassium in their diet, so adding onion to your meals can help you meet your daily needs.

Antioxidant and Anti-inflammatory Properties of Onion :-

Onion contains many antioxidants and sulfur-containing compounds that can protect your cells from oxidative stress and inflammation. Oxidative stress and inflammation are linked to various chronic diseases, such as cancer, diabetes, and heart disease.

One of the most abundant antioxidants in onion is quercetin, a flavonoid that has been shown to lower blood pressure, reduce cholesterol levels, and prevent blood clots. Quercetin may also have anticancer effects by inhibiting the growth and spread of tumor cells.

Another important antioxidant in onion is allicin, which is also found in garlic and other Allium vegetables. Allicin is responsible for the pungent smell and taste of onion, but it also has potent antibacterial, antiviral, antifungal, and anti-inflammatory properties (4). Allicin may help fight infections, reduce inflammation, and modulate immune responses.

Health Benefits of Onions :-

Onions are low in calories but high in vitamins, minerals, fiber, and antioxidants. They also contain compounds that may lower cholesterol, blood pressure, blood sugar levels, and inflammation. Some of the health benefits of onions are:

Health Benefits of Onions

Packed with nutrients :-

Onions provide various nutrients that are essential for your body’s functioning and well-being. For example, one medium onion (110 grams) contains 44 calories, 1.1 grams of protein, 9.3 grams of carbs (including 4.2 grams of sugar and 1.7 grams of fiber), 0.1 grams of fat, 9% of the Daily Value (DV) of vitamin C, 3.4% of the DV of potassium, and small amounts of other vitamins and minerals.

Benefits of Onion for Heart Health :-

Onion may benefit your heart health by lowering your risk factors for cardiovascular disease. Several studies have found that consuming onion can lower blood pressure, cholesterol levels, and triglyceride levels.

For example, a small study in 70 people with overweight and hypertension found that taking a daily dose of 162 mg of quercetin-rich onion extract for 6 weeks significantly reduced systolic blood pressure by 3.6 mmHg compared to placebo

Another study in 54 women with polycystic ovary syndrome (PCOS) found that eating 80–120 grams of raw red onion per day for 8 weeks lowered total cholesterol by 15% and LDL (bad) cholesterol by 20% compared to baseline.

Additionally, onion may prevent the formation of blood clots by inhibiting platelet aggregation (8). This may reduce the risk of stroke and heart attack.

Loaded with antioxidants :-

Antioxidants are compounds that inhibit oxidation, a process that may lead to cellular damage and contribute to diseases such as cancer, diabetes, and heart disease6. Onions are an excellent source of antioxidants and contain at least 17 types of flavonoids. Quercetin is the most abundant flavonoid
in onions and has been shown to have anti-cancer, anti-diabetic, anti-allergic, and neuroprotective effects. Other flavonoids in onions include anthocyanins, which give red onions their color and may protect against heart disease, and fisetin, which may improve memory and brain health.

May have anticancer properties :-

Several studies have suggested that eating onions may lower the risk of various types of cancer, such as stomach, colorectal, breast,ovarian, prostate, and lung cancer . This may be due to the high content of antioxidants and sulfur-containing compounds in onions that may modulate cellular pathways
involved in cancer development. For instance, onion extract has been found to inhibit the growth and spread of human liver cancer cells in test-tube studies. Moreover, onion consumption has been associated with increased levels of glutathione S-transferase (GST), an enzyme that helps detoxify carcinogens in the body.

Benefits of Onion for Blood Sugar Regulation :-

Onion may also help regulate your blood sugar levels by improving insulin sensitivity and glucose metabolism. Insulin is a hormone that allows your cells to take up glucose from the blood and use it for energy. Insulin sensitivity refers to how well your cells respond to insulin.

Several animal studies have shown that onion extract can lower blood sugar levels and increase insulin sensitivity in diabetic rats (9). Moreover, some human studies have found that eating onion can reduce fasting blood sugar levels and postprandial glucose levels.

For instance, a study in 42 people with type 2 diabetes found that consuming 100 grams of fresh red onion reduced fasting blood sugar levels by about 40 mg/dL after 4 hours.

Another study in 24 people with type 2 diabetes found that eating 50 grams of raw white onion with a meal reduced postprandial glucose levels by about 20 mg/dL after 2 hours compared to no onion.

Benefits of Onion for Bone Health :-

Onion may also have positive effects on your bone health by increasing bone density and preventing bone loss. Bone density refers to the amount of mineral matter per square centimeter of bone. It is a measure of bone strength and quality.

Several studies have suggested that onion consumption is associated with higher bone density and lower risk of osteoporosis, especially in postmenopausal women.

For example, a study in 507 perimenopausal and postmenopausal women found that those who ate onions at least once a day had 5% higher bone density than those who ate onions less than once a month.

Another study in 24 postmenopausal women found that eating 100 grams of fresh onion per day for 8 weeks increased bone mineral density and decreased markers of bone resorption, which is the process of breaking down bone tissue.

The mechanism behind the beneficial effects of onion on bone health is not fully understood, but it may involve the modulation of estrogen receptors, the inhibition of osteoclasts, and the stimulation of osteoblasts (16). Estrogen receptors are proteins that bind to estrogen, a hormone that regulates bone metabolism. Osteoclasts are cells that break down bone tissue, while osteoblasts are cells that build new bone tissue.

Have antibacterial properties :-

Onions have been used for centuries as a natural remedy for infections and wounds. They contain substances that may inhibit the growth of harmful bacteria, such as Escherichia coli (E. coli), Pseudomonas aeruginosa, Staphylococcus aureus (S. aureus), and Bacillus cereus. One test-tube study found that onion extract was able to kill Streptococcus mutans (S. mutans), a bacterium that causes tooth decay. Another test-tube study showed that onion juice was effective against Salmonella typhimurium (S. typhimurium), a bacterium that causes food poisoning.

Promote digestive health :-

Onions are rich in prebiotic fibers, such as fructans, which feed the beneficial bacteria in your gut. This leads to the formation of short-chain fatty acids (SCFAs), such as butyrate, which may improve colon health, reduce inflammation, and cut your risk of colon cancer . Additionally, onions may help relieve constipation by increasing stool frequency and weight.
