In an Instagram post shared on July 23, Dr Naveen Bhamri, cardiologist, MD, DM, explained how sugar is silently destroying our health, and we don’t even realise it. He wrote, “From spiking your insulin to inflaming your arteries, the sweet stuff is doing more harm than you think. If you’ve been craving sugar daily, it’s time to ask: Is it worth the risk?”
What is the impact of sugar on cardiac health?
Sharing how sugar harms your cardiac health and causes other health ailments, Dr Bhamri wrote, “It’s not just about weight anymore — it’s about survival.”
The cardiologist stressed that if someone were to ask him one thing, which is ‘What is poison for your body?’ He will easily name sugar. According to the cardiologist, sugar is the most dangerous item available on earth. He stated: “It's the most dangerous, because sugar is responsible for increasing your cholesterol levels, it damages your organs by causing a spike in your body, it causes organ injury, leads to insulin resistance, and causes obesity, too.”
“According to me, there should not be sugar in your meals. People often say white sugar is better than brown sugar; I say no sugar,” he added.
Apart from the above-mentioned risks, sugar is also responsible for:
- Fatigue
- Constant cravings
- Increased heart risk
- Brain fog
- Inflammation everywhere
