Vitamin B3 (Niacin) Foods - Best Foods to Include in Your Diet

You do not always need to make major changes to your diet to get appropriate essential nutrients. Many everyday foods can contribute valuable amounts of vitamins, but some are particularly useful sources. This is also true for vitamin B3, which can be found in both animal- and plant-based foods.

So, what niacin rich foods should be on your plate, and how many nutrients do they contribute? Keep reading to learn about the vitamin B3 food niacin to get a nutrient-rich meal.

What is Vitamin B3 and Why is it Important?

Niacin, also called vitamin B3, is a water-soluble vitamin that is needed to turn food into energy. It plays a major role in maintaining normal functioning of the nervous system, digestive system and skin, as well as immune function and general cell health.

So, it is essential to have enough vitamin B3 foods for general well-being. Niacin is not stored in the body in large quantities, so it must be obtained regularly from the diet.

7 Foods With Vitamin B3 Niacin

These top 7 foods with vitamin B3 that you can incorporate into meals for a healthy diet:

1. Chicken Breast

Chicken breast is a lean protein and one of the richest sources of vitamin B3 foods. It also contains vitamin B6, phosphorus and selenium as well as all the essential amino acids necessary for protein synthesis.

Chicken can be grilled, cooked in the oven, roasted, or used in soup, salad or sandwiches. You can combine chicken with vegetables and whole grains for a well-rounded meal, to get protein, fibre and other important nutrients.

2. Anchovies

Anchovies are a small but concentrated source of seafood niacin. Just one can of anchovies adds to the daily intake of niacin in your diet. They are also a source of selenium and can be used in salads, sauces, pasta and sandwiches to enhance flavour and nutrition.

3. Peanuts

Peanuts are a source of plant-based protein, healthy unsaturated fats, fibre and niacin. They are also packed with vitamin E, magnesium and other nutrients.

Peanuts can be eaten as a snack or added to oatmeal, salads and stir-fries. Whole grain toast or fruits combined with natural peanut butter can also be a good option. Since peanuts are relatively an energy-dense food, keeping portion sizes in check is important.

4. Green Peas

Green peas are rich in plant-based protein, fibre, vitamins, minerals and niacin. As they are also a source of fibre, they can support digestive health and promote fullness.

Fresh or frozen peas can be used in rice dishes, soups, curries or pasta and salads. They can also be used in combination with other legumes and vegetables to provide variety in a meal.

5. Brown Rice

Brown rice is a whole grain that has more of the grain's natural components than white rice. It, in addition to niacin, contains fibre, magnesium and other nutrients.

Brown rice can be used in a grain bowl or with vegetables and legumes, fish or lean meat. You can also boost fibre levels by substituting some refined grains with whole grains.

6. Avocado

Avocado is a source of niacin, monounsaturated fats, fibre, folate, vitamin K, vitamin E and potassium. It is creamy in texture and can be easily added to various meals.

Avocado can be incorporated into salads, sandwiches, wraps and whole-grain toast. Mashed avocado may also be eaten as a spread or as an accompaniment to eggs and vegetables.

7. Mushrooms

Mushrooms contain niacin and can contribute to overall vitamin B3 intake as part of a balanced diet. They are also a source of nutrients like riboflavin, selenium and potassium.

Mushrooms are naturally low in calories and can be used to add flavour to soups, stir-fry, omelettes, pasta, salads and grain-based foods.

What Happens When the Body Lacks B3 Vitamin Rich Foods?

Vitamin B3 food deficiency is a widespread disorder that can impact many body systems, like:

• In severe cases, niacin deficiency may result in skin rashes and may progress to pellagra (a condition that primarily affects the skin, digestive system and nervous system)
• Vitamin B3 deficiency may cause diarrhoea.
• Severe deficiency may lead to confusion, memory loss and dementia.
• Inadequate niacin intake may be associated with symptoms such as fatigue, although these symptoms are not specific to niacin deficiency.

How Much Niacin is Required by the Body?

Here's how much niacin is typically required by the body:

Note: The amount of niacin needed each day depends on age and sex. The recommended intake is in terms of niacin equivalents (NE) because niacin can be synthesised from the amino acid tryptophan, which is present in protein-rich foods.

Niacin (vitamin B3) contributes to normal energy metabolism, nervous system function, and the maintenance of healthy skin. However, no single vitamin or vitamin-rich food can prevent, treat, or cure diseases on its own. Niacin-rich foods should be consumed as part of a balanced diet and healthy lifestyle. Individual nutritional requirements may vary, and anyone concerned about nutrient deficiencies should seek advice from a qualified healthcare professional.
