# Carbs Blood Sugar Guide

CARBS & BLOOD SUGAR SPIKES Nutrition Reference  Educational Use It is not just which carb you eat, but what you eat it with. Page 1 Carbs and Blood Sugar: Fast vs Slow Which carbs spike glucose, which don't, and how fibre and protein flatten the curve Not all carbs behave the same. Some send blood sugar up quickly, others release it slowly. The speed depends on the type of carb, how it is processed and cooked, the portion, and what you eat it with. This guide sorts common Indian carbs into fast, medium and slow, then shows how fibre and protein reduce spikes, with examples you can use today. Values are approximate glycemic index (GI) figures, where 70 and above is high, 56 to 69 medium and 55 or below low. 1. What Decides How Fast Carbs Hit Beyond the food name Why this matters: How quickly a carb raises blood sugar depends on more than the food name. Knowing these factors helps you make better choices without cutting carbs out. FACTOR WHAT HAPPENS WHAT TO DO Type of carb Simple sugars and refined starches break down fast. Complex carbs in whole foods break down slowly. Choose whole, minimally processed carbs most of the time. Processing Polishing, grinding and puffing remove fibre and make starch easier to digest, so sugar hits the blood faster. Whole grains over flour, flour over puffed or instant products. Cooking and ripeness Overcooked, mashed or very ripe foods digest faster. Al dente and less ripe foods are slower. Don't overcook rice or pasta, and choose just-ripe fruit. Portion size (glycemic load) The glycemic index (GI) ranks how fast a carb raises sugar. The glycemic load (GL) also counts the amount eaten. A small portion of a high-GI food can have a lower impact than a large portion of a medium one. What you eat with it Fibre, protein and fat slow stomach emptying and sugar absorption. Never eat a carb alone, and build the meal around it. 2. Fast Carbs (High GI) Sharper spikes Why this matters: These carbs are digested and absorbed quickly, causing sharper rises followed by sharper falls. GI values are approximate and vary with variety, cooking and ripeness. FOOD APPROX. GI WHY IT SPIKES BETTER CHOICE White rice (polished) about 70 to 90 Starch is quickly broken down, especially when soft and sticky. Parboiled, basmati or brown rice, smaller portion, plus dal and veg White bread, maida, naan, biscuits about 70 to 75 Refined flour with little fibre digests rapidly. Whole wheat or multigrain roti, ragi or jowar roti Potato (mashed, baked, fries) about 80 to 90 Very digestible starch. Boiled and cooled potato is lower. Small portion of boiled potato with skin, or sweet potato Puffed rice (murmura) and cornflakes about 80 to 90 Puffing and processing make starch very quick to absorb. Oats, roasted chana, nuts and seeds Idli and rice-based tiffins about 70 Finely ground rice batter is digested fast. Sambar and chutney slow it. Add lots of sambar, a protein side and fewer idlis, or try ragi or oats idli

CARBS & BLOOD SUGAR SPIKES Nutrition Reference  Educational Use It is not just which carb you eat, but what you eat it with. Page 2 FOOD APPROX. GI WHY IT SPIKES BETTER CHOICE Sugar, sweets, soft drinks about 65 to 100 Pure or concentrated sugar enters blood quickly. Whole fruit, dates in small amounts, and sweets after a meal, not alone Fruit juice about 50 to 70 Removes the fibre, so the sugar is absorbed quickly. Whole fruit with its fibre Watermelon about 70 to 80 High GI but little carb per serving, so the load is low. Fine in moderate portions, ideally with nuts or curd 3. In-Between Carbs (Medium GI) Depends on how you eat them Note: These sit in the middle. How you cook them and what you eat them with matters most. FOOD APPROX. GI NOTES Whole wheat roti or bread about 55 to 70 More fibre than maida, but still starchy. Pair with dal or paneer. Brown rice and basmati rice about 50 to 68 Slower than polished white rice, especially in measured portions. Poha about 60 to 70 Flattened rice digests fairly fast. Add peanuts, vegetables and curd. Ripe banana, mango, pineapple about 50 to 65 Natural sugar with some fibre. Eat with nuts or curd. Rolled oats and muesli about 55 to 60 Soluble fibre (beta-glucan) helps. Choose unsweetened. Boiled sweet potato about 50 to 63 Fibre and slower starch than potato. Eat with skin. 4. Slow Carbs (Low GI) Steadier energy Why this matters: These raise blood sugar slowly and steadily, and make good everyday carbs. FOOD APPROX. GI WHY IT'S SLOW Dal and legumes (moong, chana, rajma, lentils) about 20 to 40 High in fibre and protein, with slowly digested starch. Steel-cut oats, barley, quinoa about 28 to 55 Intact grains with soluble fibre. Ragi, jowar, bajra and other millets medium to low More fibre than polished rice. Responses vary by form and cooking. Most vegetables (non-starchy) low Very little carb and lots of fibre. Apple, orange, guava, pear, berries about 25 to 45 Fibre, and fruit sugar that is absorbed more slowly. Eat whole. Curd, milk about 30 to 40 Protein and fat slow absorption, and lactose is a slower sugar. Nuts and seeds very low Mostly fat, protein and fibre with little carbohydrate. Parboiled rice about 40 to 65 Often lower than raw milled rice. Choose it over polished white.

How Fibre Reduces Spikes And examples to use How it works: Fibre is the part of plant foods we don't fully digest. It slows sugar absorption in the gut and feeds helpful gut bacteria. FIBRE SOURCE HOW IT WORKS HOW TO ADD IT Soluble fibre: oats, chia, flax, psyllium, beans, apples Forms a gel in the gut that slows stomach emptying and traps sugars, so glucose enters the blood more gradually. Oats or chia pudding, flax in rotis, a bowl of beans or dal. Insoluble fibre: whole wheat, vegetables, skins of fruit Adds bulk and keeps starch inside intact plant cell walls, so less is digested at once. Whole grain roti, vegetables in every meal, fruit with skin. Vegetables and salad Fill the plate and slow the meal. Eating them first has been linked with lower post-meal sugar. A bowl of salad or sabzi before the main meal. Legumes and sprouts Fibre and protein together, with starch that is slowly digested. Add dal or sprouts to rice, rotis or snacks. Seeds (chia, flax, sabja) Swell and form a gel, giving a strong slowing effect in small amounts. 1 tsp in curd, smoothie or water. Whole fruit instead of juice The fibre in the fruit slows the sugar absorption. Eat the apple, don't drink it. 6. How Protein Reduces Spikes And examples to use How it works: Protein slows digestion and triggers hormones that help the body handle sugar. Even a modest amount per meal can make a difference. PROTEIN SOURCE HOW IT WORKS HOW TO ADD IT Curd, paneer, milk Protein slows stomach emptying and stimulates gut hormones (like GLP-1) and insulin release, which lower the post-meal rise. Curd with rice, paneer with roti, milk with oats. Dal, chana, rajma, sprouts Plant protein plus fibre double the effect. Dal with rice or roti, sprouts chaat before a meal. Eggs, fish, chicken Lean protein sources that blunt the spike when eaten with carbs. Egg with toast, fish curry with rice. Tofu, soya chunks High protein, low-GI foods that can replace part of the carb. Soya pulao, tofu bhurji with roti. Nuts and nut butters Protein and healthy fat slow digestion further. A handful with fruit, or peanut butter on bread. Protein powder (optional) Whey taken before a meal has lowered post-meal glucose in studies. A scoop in water or milk 10 to 20 minutes before the meal.

Smart Combinations Turn fast carbs into balanced meals Why this works: You don't have to give up favourite carbs. Add fibre and protein and the same food behaves differently. CARB PAIR WITH WHY IT HELPS White rice Dal, sabzi, curd and salad Fibre and protein slow the digestion of the rice. Roti Paneer, dal, vegetables, curd Lower overall meal impact than roti with just ghee or pickle. Idli or dosa Sambar, chutney, a protein side Dal in sambar adds protein and fibre. Poha or upma Peanuts, vegetables, curd or sprouts Turns a fast carb into a balanced plate. Fruit Nuts, curd or paneer Slows sugar absorption and keeps you full. Oats Chia, nuts, seeds, milk or curd More fibre, protein and fat. Bread Egg, paneer, peanut butter and vegetables A better balance than bread with jam. Sweets Eat after a meal, in a small portion A meal slows the spike compared with sweets on an empty stomach. 8. Meal Habits That Help Order, movement and portions Why this works: Small habits around meals add to the effect of the foods themselves. HABIT WHY IT HELPS HOW TO DO IT Eat in order: vegetables, then protein, then carbs Fibre and protein first slow the carbs that follow. Studies show lower post-meal glucose with this order. Start with salad or sabzi, then dal or paneer, then rice or roti. Walk after meals Muscles use glucose when you move, flattening the peak. 10 to 15 minute walk within an hour of eating. Watch portions of starch Even slow carbs raise sugar if the portion is large. About a quarter of the plate for rice or roti. Cool cooked rice or potato Cooling creates some resistant starch, which digests more slowly. The effect is small. Cook and cool, then reheat if you like. Don't skip meals then binge Long gaps lead to large, fast carb meals. Eat balanced meals at regular times. Sleep and stress Poor sleep and stress raise blood sugar and insulin resistance. Aim for 7 to 8 hours and regular relaxation. Note: GI values are approximate and vary by variety, cooking, ripeness and the individual. Blood sugar responses differ from person to person.
