Common foods that increase blood sugar levels you should avoid

 

Diabetics should always be careful about their diet. However, many common foods that we think are fine and sugar-free can actually raise blood sugar levels. Let's find out what they are.

The white rice we eat daily can potentially increase blood sugar levels. White rice is very low in fiber. Due to the lack of fiber, blood sugar rises quickly after eating it.

Dishes like naan and poori are common at home. But their glycemic index is very high. Since refined flour is low in fiber and oil is used, the body quickly converts it to sugar.

We often use jaggery as a healthy alternative to sugar. However, jaggery also has a high glycemic index.

Juices that come in bottles and packets can quickly raise blood sugar levels. This is because they contain no fiber at all.

People with diabetes should avoid potato fries, potato masala with parotta, and aloo paratha. These can increase blood sugar levels.

Crispy and salty snacks like samosas and pakodas, which we eat with tea, also have a high glycemic index. This raises blood sugar.

Eating sweet fruits like mangoes, grapes, and sapodilla introduces a lot of natural sugar into the body. Drinking them as juice can cause a rapid spike in blood sugar due to fiber loss.

When it comes to managing blood sugar, the goal isn't just about cutting out table sugar; it’s about identifying foods that rank high on the Glycemic Index (GI). High-GI foods break down rapidly during digestion, releasing a sudden surge of glucose into the bloodstream.

If you are looking to prevent steep blood sugar spikes and crashes, here are the most common foods to limit or avoid, along with smart swaps for each.

---

1. Refined White Grains

During processing, refined grains have their bran and germ stripped away, removing almost all fiber, vitamins, and minerals. Without fiber to slow down digestion, the remaining starch converts to glucose almost instantly.

• Foods to limit: White bread, white rice, regular white pasta, and flour tortillas.

• The Swap: Whole grain or sprouted bread, brown rice, quinoa, and chickpea- or lentil-based pastas.

2. Liquid Sugars (Sodas, Juices, and Sweet Teas)

Liquid carbohydrates are arguably the fastest route to a blood sugar spike. Because there is zero solid food or fiber for your stomach to process, the sugar is absorbed into your bloodstream within minutes.

• Foods to limit: Regular sodas, sweetened iced teas, sports drinks, energy drinks, and even 100% fruit juices (which lack the fiber of whole fruit).

• The Swap: Sparkling water with a squeeze of fresh lime, herbal teas, or infusing water with sliced cucumber and mint.

  
  
  

3. Ultra-Processed Breakfast Foods

Many foods marketed as morning health options are secretly loaded with refined flours and added sugars, causing an early-morning insulin spike that leaves you fatigued a few hours later.

• Foods to limit: Boxed sugary cereals, instant flavored oatmeal packets, pastries, muffins, and pre-made pancakes or waffles.

• The Swap: Steel-cut oats topped with walnuts and cinnamon, or a vegetable omelet with a side of avocado.

4. Specific High-Starch Vegetables

While vegetables are generally excellent for health, certain root vegetables and tubers have a high glycemic load because they contain dense amounts of fast-digesting carbohydrates.

• Foods to limit: White potatoes (especially mashed, baked, or fried), corn, and pumpkin.

• The Swap: Sweet potatoes (which have a lower GI than white potatoes), cauliflower mash, or roasted root vegetables like carrots and turnips in moderation.

5. "Healthy" Natural Sweeteners

A common misconception is that natural or organic sugars don't spike blood sugar. While some contain trace minerals, your liver and bloodstream process them very similarly to white cane sugar.

• Foods to limit: Honey, agave nectar, maple syrup, coconut sugar, and molasses.

• The Swap: Use these very sparingly, or opt for natural, non-glycemic alternatives like pure stevia or monk fruit extract if you need sweetness without the spike.

6. Processed Snack Foods

Crackers, chips, and pretzels are typically made from refined flour, bad fats, and hidden sugars. They lack the protein or fiber needed to satisfy hunger, leading to overeating and volatile blood sugar levels.

• Foods to limit: Potato chips, saltine crackers, pretzels, and packaged rice cakes.

• The Swap: A handful of almonds or walnuts, pumpkin seeds, celery sticks with peanut butter, or roasted chickpeas.

  
  
  

7. Dried Fruits and Sweetened Dairy

While fresh, whole fruit contains fiber that blunts a glucose spike, dried fruit is highly concentrated in sugar and incredibly easy to overeat. Similarly, dairy products are often treated as protein sources but can hide massive amounts of added sugar.

• Foods to limit: Raisins, dried dates, sweetened dried cranberries, flavored yogurts, and ice cream.

• The Swap: Fresh, whole berries (strawberries, blueberries, raspberries), and plain Greek yogurt or curd (which you can flavor yourself with a dash of vanilla extract or a few fresh berries).

---

💡 The Golden Rule for Blood Sugar Balance:

If you do eat a high-carbohydrate food, always pair it with a protein, a healthy fat, or fiber. For example, if you eat a piece of fruit, pair it with a handful of almonds. The fat and protein will slow down your gastric emptying, drastically flattening the resulting blood sugar curve.

Side effects of ashwagandha: 7 risks you should know before taking this herb

 

Ashwagandha, often called Indian ginseng, is one of the most popular Ayurvedic herbs known for reducing stress, improving energy, and supporting overall wellness. While it has many proven health benefits, few people realise that ashwagandha also carries certain risks. According to the NIH, like any supplement, it can cause side effects, especially when taken in high doses or without medical guidance. From stomach upset and drowsiness to more serious concerns like low blood pressure, drug interactions, and pregnancy risks, it’s important to know the downsides too. Here are seven hidden side effects of ashwagandha you should understand before adding it to your routine.

7 potential side effects of ashwagandha

Gastrointestinal Issues

One of the most common side effects of ashwagandha is digestive discomfort. Some people may experience nausea, diarrhoea, or an upset stomach, especially when taking higher doses. This happens because ashwagandha contains compounds that can irritate the gastrointestinal lining in sensitive individuals. Mild bloating or gas may also occur in some users, particularly during the first few days of supplementation. To minimise these effects, it is best to start with a small dose and take the supplement with food. Drinking plenty of water and avoiding taking it on an empty stomach can also help reduce the risk of stomach irritation.

Allergic reactions

Although rare, allergic reactions to ashwagandha are possible. Since it belongs to the Solanaceae family—the same group as tomatoes, potatoes, and eggplants—people allergic to these foods may also react to ashwagandha. Symptoms of an allergic reaction may include rashes, itching, swelling, or difficulty breathing. If you notice any of these warning signs after taking ashwagandha, it is important to discontinue use immediately and seek medical advice. Performing an allergy test before long-term use may be beneficial for those with a history of plant allergies.

Interaction with medications

Ashwagandha is a powerful herb, which means it can interact with certain prescription medications. It may interfere with thyroid medicines, diabetes drugs, blood pressure medications, and immune-suppressing treatments. Additionally, ashwagandha has mild sedative properties, which can intensify the effects of sleeping pills or anti-anxiety medications. For this reason, individuals already on medication should consult a healthcare provider before starting ashwagandha supplements to avoid harmful drug interactions.

Sedative effects

While ashwagandha is well-known for reducing stress and promoting relaxation, its calming effects can sometimes go too far. In some individuals, it may cause excessive drowsiness, dizziness, or fatigue, particularly when combined with alcohol or other sedatives. This makes it important to avoid driving or operating heavy machinery after consuming higher doses of ashwagandha. People who already struggle with low energy or chronic fatigue should use it cautiously to prevent worsening their symptoms.

Hypotension (Low Blood Pressure)

Ashwagandha has been shown to lower blood pressure in some individuals, which may be beneficial for those with hypertension. However, this effect can become risky for people who naturally have low blood pressure or are already on blood pressure medications. A sudden drop in blood pressure may lead to dizziness, fainting, or light-headedness. To avoid complications, it is recommended that people with blood pressure concerns monitor their levels closely when using ashwagandha and consult a doctor if any unusual symptoms appear.

Pregnancy and breastfeeding risks

There is still limited research on the safety of ashwagandha during pregnancy and breastfeeding. Some traditional practices suggest that it may support fertility and reproductive health, but modern studies are not sufficient to prove its safety. In fact, high doses of ashwagandha may potentially trigger uterine contractions, which could increase the risk of miscarriage. For breastfeeding mothers, the herb’s impact on infants remains unclear. Because of these uncertainties, pregnant and nursing women are strongly advised to avoid ashwagandha unless prescribed by a qualified healthcare professional.

Thyroid disorders

Ashwagandha appears to influence thyroid hormones, but its effects can be unpredictable. Some studies suggest that it may increase thyroid hormone levels, which could worsen hyperthyroidism, while others indicate it may help balance thyroid function. This dual action makes it risky for people with thyroid conditions who are already on medication, as it may either over-stimulate or suppress hormone production. Anyone with hypothyroidism or hyperthyroidism should only take ashwagandha under strict medical supervision.

Ashwagandha offers a wide range of health benefits, from reducing stress to improving immunity, but it is not without risks. Side effects such as digestive issues, drowsiness, low blood pressure, and drug interactions are possible, and special caution is needed for pregnant women and individuals with thyroid disorders.

Like any supplement, the key to safe use is moderation and professional guidance. If you are considering adding ashwagandha to your daily routine, consult a healthcare provider first, especially if you are on medication or managing a chronic condition. Taken responsibly, ashwagandha can be a powerful ally for health and wellness, but ignoring its side effects may do more harm than good.

Always seek the guidance of a qualified healthcare provider regarding any medical condition or lifestyle change.While Ashwagandha (Withania somnifera) is highly celebrated in Ayurvedic medicine and widely used as an adaptogen to manage stress, anxiety, and fatigue, it is a potent herb that is not suitable for everyone.

If you are considering adding it to your routine, here are 7 crucial side effects and risks you should know:

1. Risk of Liver Injury (Hepatotoxicity)

In recent years, medical regulators in several countries (including Denmark and parts of Europe) have raised concerns or issued warnings regarding ashwagandha and liver health. While relatively rare, there have been documented clinical cases of drug-induced liver injury associated with ashwagandha use. Symptoms like yellowing of the eyes or skin (jaundice), dark urine, and severe fatigue should prompt immediate discontinuation.

2. Gastrointestinal Distress

This is one of the most common acute side effects, especially when ashwagandha is taken on an empty stomach or in large doses. It can irritate the mucosal lining of the stomach, leading to:

• Nausea and upset stomach

• Diarrhea

• Vomiting or abdominal cramps

3. Thyroid Hormonal Shifts

Ashwagandha can stimulate the thyroid gland, increasing the production of thyroid hormones (T3 and T4).

• The Risk: If you have hyperthyroidism (an overactive thyroid), taking ashwagandha can exacerbate the condition or trigger thyrotoxicosis (a dangerous excess of thyroid hormones). Even if you have hypothyroidism and take thyroid medication (like levothyroxine), ashwagandha might cause your hormone levels to spike too high.

4. Severe Risks in Pregnancy and Breastfeeding

Pregnant women should strictly avoid ashwagandha. The herb contains compounds that can act as an abortifacient, potentially inducing uterine contractions, premature labor, or miscarriage. There is also insufficient safety data regarding its active compounds passing into breast milk, so it is recommended to avoid it while breastfeeding.

5. Blood Sugar and Blood Pressure Spikes or Drops

Ashwagandha is known to lower both blood sugar and blood pressure. While this sounds beneficial, it poses a direct risk if you take medications for diabetes or hypertension:

• Hypoglycemia: It can enhance the effect of insulin or oral diabetes drugs, causing blood sugar to drop dangerously low.

• Hypotension: It can synergize with blood pressure medications, causing sudden dizziness, fainting, or fatigue due to excessively low blood pressure.

  
  
  

6. Immune System Stimulation (Autoimmune Risks)

Because ashwagandha modulates and boosts certain aspects of the immune system, it can trigger flare-ups in individuals with autoimmune diseases. If you have conditions such as Rheumatement arthritis, Lupus (SLE), Multiple Sclerosis (MS), or Hashimoto's thyroiditis, the herb may cause your immune system to become more aggressive against your own tissues.

7. Excessive Drowsiness and Sedation

Ashwagandha has a calming effect on the central nervous system and is often used to improve sleep. However, this sedative property can cause daytime drowsiness or sluggishness.

• Medication Interactions: It interacts strongly with central nervous system depressants, sedatives, and sleep medications (such as benzodiazepines, barbiturates, or over-the-counter sleep aids), multiplying their sedative effects to an unsafe degree.

Safe Usage Tips:

• Standardize the Dose: Stick to clinically studied extracts (like KSM-66 or Shoden) where active withanolide percentages are controlled, and follow recommended dosages.

• Cycle It: Many herbalists recommend cycling ashwagandha (e.g., taking it for 2–3 months, then taking a 2–4 week break) rather than continuous long-term use.

• Consult a Professional: If you take any regular prescription medications or have a chronic health condition, always consult a healthcare provider before starting ashwagandha.
