Eating Leftover Rice Stored Improperly Could Cause Vomiting and Diarrhea; Dietician Avni Kaul Says How It Needs to be Stored

Rice boasts essential nutrients that support your body and furnish the energy needed for your daily activities. Nevertheless, consuming improperly stored or reheated leftover rice can result in digestive discomfort and the risk of foodborne illnesses, explains India’s top Dietician for gastrointestinal health Avni Kaul.

Are you aware of the fried rice syndrome?

After cooking and consuming rice, any excess may be inadvertently left at room temperature for hours, or even overnight. Unfortunately, this creates an environment conducive to bacterial contamination and rapid proliferation. This occurrence is commonly referred to as the “fried rice syndrome.”

What type of bacteria is found in rice?

Bacillus cereus is one of the prevalent bacteria found in rice. This spore-forming microorganism can flourish when the rice becomes contaminated, generating toxins that have the potential to induce food poisoning.

Reheating might not work

The toxins produced by B. cereus in starchy foods exhibit heat resistance. Consequently, reheating leftover rice might not effectively eliminate the bacteria, leaving the potential for food poisoning. It is crucial to recognize that this risk isn’t exclusive to rice alone; any type of grain could harbor bacteria if not stored and reheated properly.

What is the correct way to store the leftover rice for later use?

Bacteria could undergo quick proliferation if rice remains within the temperature range of 40 to 140 degrees Fahrenheit (4 to 60 degrees Celsius) for more than two hours. As a precaution, rice should not be left at room temperature for over two hours, and this duration should be reduced to one hour if the ambient temperature exceeds 90 degrees Fahrenheit or 32 degrees Celsius. To ensure the safety of your leftover rice against harmful bacteria causing food poisoning, it is important to transfer the rice into a covered container and promptly refrigerate it once it cools down. When stored in a refrigerator maintained below 40 degrees Fahrenheit (4 degrees Celsius), leftover rice can be safely consumed for up to four days.

What is the correct method for reheating leftover rice?

For safe consumption of leftover rice, it is recommended to reheat it only once. Opt for reheating only the necessary portion instead of the entire batch. Make sure that both rice and any leftover pasta are heated to an internal temperature of 165 degrees Fahrenheit (74 degrees Celsius). Enjoy your meal!

Avni approaches nutrition and wellbeing in a genuinely scientific and highly customized way. Her knowledge is impressive, but what truly stands out is the personalized element—it's clearly not a rigid, one-size-fits-all plan. I really appreciate that the process is designed to be flexible and adaptable to individual preferences and lifestyles. Beyond the methodology, the attention to detail and the support system she sets up are exceptional. She ensures the journey of nutritional improvement doesn't feel weary or lonely. Loved the gamification elements which made the process fun while encouraging a focus on sustainable, long-term habits. Would definitely recommend!!

When looking for someone to help you through your health journey, I think it is very important that the people who are guiding you do not approach it with any judgement. That is one of the best things I find about Avni & her team. They don't make food your enemy but rather teach you how to do it right, spending a lot of time in understanding your likes and dislikes and really personalising it to your need. You can be sure that you are being looked after individually. Alongside that, they also offer is a wealth of knowledge but also a delicate approach towards your journey. This is the main reason why I would recommend Avni to everyone.

In March 2025, I had a scare with a sudden spike in my sugar levels. That was my wake-up call—I knew it was time to take my health seriously. I wasn’t looking for a quick fix but a long-term, sustainable lifestyle change. That’s when a close friend introduced me to Avni and NutriActivania. I reached out to Avni, and we discussed my goals and what I hoped to achieve. She and her team immediately put together a plan tailored specifically for me. The best part was how flexible it was—no drastic cuts, no extreme measures. Instead, they focused on equipping me with the skills and habits I needed to make lasting lifestyle changes. They listened to what worked for me, especially in terms of food preferences, and built a plan around my life rather than expecting me to adjust to theirs. That level of customization is what made it easy for me to stay committed. Each week, they share a personalised food plan and always check in before finalizing it. Avni has been incredibly supportive—always available to answer questions and consistently encouraging me to stay on track. Over the last seven months, I have lost 9 kgs. My sugar levels are back to normal, my cholesterol has dropped, and most importantly, I feel healthier. I eat better, and I am far more mindful about what I consume. I truly believe they’ve given me the tools to make better choices and have been instrumental in helping me reshape my lifestyle. Thank you, Avni and team. Thank you for being part of my journey and for helping shape it in the best way possible.

During my first pregnancy, I was worried because I didn’t know how to give proper nutrition to my baby. Someone suggested Nutritionist Avni Kaul, so I joined her program and followed her diet plan throughout my pregnancy. She gave me a healthy meal plan that also allowed me to enjoy the foods I liked. My baby girl was born healthy and at a good weight. After pregnancy, I struggled with my weight, so I joined Avni Kaul’s post-pregnancy weight loss program. My weight went from 65 kg to 56 kg. I truly thank Nutri Activania and Nutritionist Avni Kaul for their support and guidance during my pregnancy and weight loss journey.
