Are sugar alternatives truly better?

Sugar is increasingly seen as a threat to health but giving it up isn’t easy. This has driven the demand for various sugar substitutes widely believed to be healthy.
Deepika Sasmal (28) from Mumbai, a dessert lover, has recently started using monk fruit. She says “I relish my desserts guilt-free now... I feel that it is the closest alternative to sugar. Switching to monk fruit has made me feel lighter... I can also see an improvement in my skin. The best part is it has zero calories.”
Similarly, Akshay Saraswat (34) from Bhopal too, has switched to sugar alternatives. “I first tried stevia but didn’t like its bitter aftertaste. Now I use a monk fruit and erythritol substitute that tastes like sugar with no aftertaste.”
Anushka (25) from Mumbai also uses monk fruit and stevia. “I haven’t noticed major changes, but it helps to know it’s better for my body than refined sugar.”

Many such individuals turn to these alternatives for health reasons, but it’s important to understand if they truly deliver the benefits. We spoke to experts who unpacked the pros and cons.

May aid weight loss
Gauri Anand, a clinical dietitian, states,
“Sugar alternatives can support weight loss when paired with a balanced diet and portion control, though effectiveness varies by type and usage.”
May trigger sugar cravings
Dr Uday Phadke, an endocrinologist and diabetologist, warns,
“Overuse of sweeteners can increase sugar cravings and lead to more sugar intake.”
Can have a laxative effect
Dr Pratayksha Bhardwaj, a weight management expert, notes that while sugar-free products are generally safe, excessive intake may cause digestive issues. “Most come with a laxative warning and can worsen stomach problems if overused,” he says.
There are several misconceptions about sugar alternatives. Dr Rajiv Kovil, a diabetologist, notes, “Many believe these substitutes are completely safe and free from side effects. While generally safe in moderation, they can cause digestive discomfort, though evidence is still inconclusive.”
Additionally, Gauri Anand shares another common misconception about jaggery and honey being a safe alternative in terms of GI index. She says, “Jaggery and honey, though natural, still have high glycaemic indexes and can spike blood sugar.”
She also points out that agave syrup, coconut sugar, and maple syrup – though marketed as low-GI – still raise blood sugar and contain fructose, which may lead to metabolic issues. “Even zero-calorie sweeteners like aspartame and stevia raise concerns about potential long-term effects. While these may be better than refined sugar, moderation is key,” she says.
Brands are innovating to meet the growing demand for sugar alternatives. Nita Purohit, chefpreneur and founder of a gourmet food kitchen, shares, "People are consciously seeking natural sweeteners or low-calorie options. I stick to dates, raisins, bananas and apples for their sweetness and added nutrients. I also use pure monk fruit sweetener but without erythritol.”

However, different dishes react differently to sugar alternatives, making it essential to adjust recipes. Shivani Sharma, chefpreneur and founder of a gluten-free kitchen, explains, “Sweeteners require recipe adjustments to maintain structure. In my gluten-free millet cakes, I use date paste and coconut sugar for moisture and sweetness. For light pastries, liquid sweeteners like maple syrup can alter the texture.”
The feedback on her sugar-free items has been positive. Sharma shares, “Clients have shared that they no longer experience the rapid spike and crash that comes with refined sugar.”
