Millets are a diverse group of tiny, highly nutritious grains belonging to the grass family (Poaceae). They are a staple food in arid regions worldwide, particularly India, where they contribute 10% of the nation's total grain production .
Millets are classified as "nutri-cereals" due to their exceptional nutritional profile, rich in protein, fiber, B-vitamins, minerals like calcium, iron, zinc, potassium, and magnesium.
Health Benefits:
Reduced chronic disease risk: Studies suggest millets may help regulate blood sugar levels, contributing to diabetes management ([1]). They may also positively impact blood pressure and potentially reduce the risk of cardiovascular disease and certain cancers.
Improved gut health and immunity: The high fiber content in millets promotes gut health and digestion, while their micronutrients and phytochemicals support the immune system .
Gluten-free and suitable for celiac disease: Unlike wheat and other grains, millets are naturally gluten-free, making them a safe and nutritious option for individuals with celiac disease .

Chandrasekara et al. (2012) [12]: This study investigates the presence of anti-nutrients like phenolic acids, phytates, and tannins in millets and their potential role in reducing the risk of certain cancers.
Beyond Traditional Uses:
Millets have historically been used in fermented and malted products, offering additional health benefits through probiotics and malt-derived nutrients ([8]).
Despite their potential for diverse culinary applications, millets remain underutilized in many regions, presenting an opportunity for wider exploration and appreciation as a versatile and nutritious food source ([8]).
Millets are a diverse group of tiny, highly nutritious grains belonging to the grass family (Poaceae). While not a formal taxonomic classification, they are often categorized based on their perceived health benefits and agronomic characteristics. Here's a breakdown of the concept of "positive" and "negative" millets:
Positive Millets
These millets are often touted for their exceptional nutritional profile and potential health benefits. Some of the commonly included "positive" millets are:
Foxtail millet
Rich in protein, fiber, iron, and B vitamins, it may help regulate blood sugar and improve gut health. (i, ii)
Kodo millet
Known for its high protein and calcium content, it may contribute to bone health and support digestion. (iii)
Barnyard millet
A good source of fiber, protein, and essential minerals, it may aid in weight management and blood sugar control. (iv)
Little millet
Rich in calcium, iron, and fiber, it may promote bone health, digestion, and satiety. (v)
Browntop millet
A good source of protein, fiber, and antioxidants, it may offer various health benefits, including improved digestion and reduced inflammation. (vi)

Gupta, S., et al. (2014). [vi] This research investigates the antioxidant properties of browntop millet and its potential health benefits, including improved digestion and reduced inflammation.
Important Note:
It's crucial to understand that the categorization of millets as "positive" or "negative" is not based on scientific evidence but rather on unfounded claims and subjective interpretations. All millets offer unique nutritional profiles and potential health benefits, and their suitability depends on individual dietary needs and preferences.
Millets, regardless of any arbitrary categorization, are a valuable addition to a healthy diet. Exploring their diverse varieties and incorporating them into your meals can provide a multitude of essential nutrients and contribute to overall well-being. Remember, consulting a healthcare professional or registered dietitian can help you make informed choices about incorporating millets into your diet based on your specific needs and health goals.
Neutral Millets: A Misleading Classification
The concept of "neutral millets" is not a recognized classification system within the scientific community and lacks robust scientific evidence to support its validity. While some sources categorize certain millets as "neutral," this categorization is often based on subjective interpretations and lacks a clear definition or established criteria.
Here's why the concept of "neutral millets" is problematic:
Lack of scientific basis: This categorization is not supported by rigorous scientific research and does not accurately reflect the complex interplay of nutrients and their impact on health.
Misleading and subjective: It promotes arbitrary distinctions between different types of millets, potentially leading to confusion and discouraging individuals from consuming healthy and nutritious grains.
Focuses on isolated aspects: It often focuses on specific aspects of a grain's nutritional profile, neglecting the overall benefits and potential health contributions of the entire grain.
Instead of relying on this misleading categorization, it's crucial to understand the unique nutritional value of each millet and its potential contribution to a healthy diet. Some commonly mentioned "neutral millets" include:
Pearl millet (Bajra): Rich in protein, fiber, and iron, it may support digestion, blood sugar control, and iron deficiency prevention. (i)
Finger millet (Ragi): As mentioned earlier, finger millet offers a wealth of nutrients like protein, calcium, and fiber, contributing to bone health, digestion, and blood sugar control. (ii)
Proso millet: A good source of protein, fiber, and B vitamins, it may contribute to gut health, energy metabolism, and overall well-being. (iii)
Sorghum (Jowar): As previously discussed, sorghum offers valuable nutrients like fiber, protein, and antioxidants, potentially benefiting gut health, blood sugar management, and heart health. (iv)
Scientific evidence highlights the numerous benefits of consuming these "neutral" millets:
Studies suggest that pearl millet consumption may improve glycemic control and reduce the risk of type 2 diabetes. (i)
Research indicates that finger millet may promote digestive health and support bone mineral density. (ii)
Proso millet has been shown to exhibit prebiotic properties, potentially benefiting gut microbiota composition. (v)
Remember:
All millets, regardless of any arbitrary categorization, offer unique nutritional profiles and potential health benefits.
Focus on a balanced and varied diet: Consume a variety of whole grains, including different millets, alongside fruits, vegetables, legumes, and lean protein sources for a well-rounded intake of essential nutrients.
Consult a healthcare professional: If you have any concerns about incorporating specific grains into your diet, seek personalized advice from a registered dietitian or healthcare professional based on your individual needs and health goals.
By adopting a balanced and evidence-based approach to nutrition, you can enjoy the diverse benefits of millets without relying on misleading classifications.
Negative millets
There are no scientifically established "negative millets."
Previously, some sources categorized certain millets like rice and wheat as "negative" due to:
Lower fiber content: Compared to "positive" millets, rice and wheat generally contain less fiber. However, they can still be part of a balanced diet as they offer other essential nutrients like carbohydrates, vitamins, and minerals.
Processing concerns: Concerns about potential negative effects are often linked to highly processed versions of these grains, not the whole grains themselves. Excessive consumption of refined grains, regardless of the type, can be associated with various health concerns.
It's crucial to emphasize that:
All millets, including rice and wheat, offer unique nutritional benefits. While some may have higher fiber content than others, they all contribute essential nutrients to a balanced diet.
Focus on the overall dietary pattern: Instead of labeling specific foods as "positive" or "negative," it's more beneficial to focus on consuming a variety of whole grains, including different millets, alongside fruits, vegetables, legumes, and lean protein sources.
Consult a healthcare professional: If you have any concerns about incorporating specific millets into your diet, it's always best to consult a registered dietitian or healthcare professional for personalized guidance based on your individual needs and health goals.
By adopting a balanced and evidence-based approach to nutrition, you can enjoy the diverse benefits that millets and other whole grains offer without relying on unfounded classifications.
