Glycemic Index, Glycemic Load And Healthy Fats

Maintaining stable blood sugar levels is essential for overall health, preventing diabetes, insulin resistance, and energy crashes. One practical approach is eating low glycemic index (GI) foods. Another is incorporating healthy fats into your diet.

This article will cover:

What is the Glycemic Index (GI)?

The Glycemic Index (GI) is a scale from 0 to 100. It ranks how quickly a food raises blood sugar levels after consumption.

Low GI (≤55) – Slow digestion, gradual rise in blood sugar (better for long-term health).
Medium GI (56–69) – Moderate impact on blood sugar.
High GI (≥70) – Rapid blood sugar spikes, leading to insulin surges and energy crashes.

Eating more low-GI foods helps improve insulin sensitivity, sustain energy, and reduce diabetes risk.

Low-GI Foods and Their Glycemic Index Values

Here’s a list of low-GI foods (GI ≤55) along with their values:

Vegetables (Low GI)

Food	GI Value
Spinach	15
Broccoli	15
Kale	15
Carrots (raw)	16
Cauliflower	15
Tomato	20
Bell Peppers	25
Eggplant	20

Fruits (Low GI)

Food	GI Value
Cherries	22
Grapefruit	25
Apples	36
Pears	38
Strawberries	41
Oranges	42
Peaches	42
Grapes	49

Grains & Legumes (Low GI)

Food	GI Value

Barley	25
Kidney Beans	24

Nuts & Seeds (Low GI)

Food	GI Value
Peanuts	14
Almonds	10
Walnuts	10
Chia Seeds	1
Flaxseeds	1
Sunflower Seeds	15

Protein Sources (Low GI)

(Note: Most protein-rich foods have a GI of nearly 0, as they do not significantly affect blood sugar.)

✔ Fish (salmon, sardines, tuna) – GI = 0
✔ Chicken – GI = 0
✔ Eggs – GI = 0
✔ Tofu – GI = 15
✔ Cheese – GI = 0

How Do These Compare to High-GI Foods?

Food	GI Value	Effect on Blood Sugar
Table Sugar (Sucrose)	65	Causes a fast spike in blood sugar
White Rice	73	Rapidly absorbed, high insulin response
White Bread	75–85	Very fast digestion, leads to sugar crashes
Instant Oatmeal	79	High GI due to processing

✔ Low-GI foods release sugar gradually, providing steady energy and preventing cravings.
✔ High-GI foods cause quick spikes and crashes, increasing diabetes and obesity risk.

Be Mindful of Glycemic Load – Low GI Doesn’t Mean Eat Unlimited Quantities

While low glycemic index (GI) foods help stabilize blood sugar levels, it’s important to remember that portion size matters.

Even with a low GI, eating large amounts of carbohydrate-rich food can still increase blood sugar levels. This is because of its glycemic load (GL).

What is Glycemic Load (GL)?

The glycemic load (GL) takes into account both:

The glycemic index (GI) of a food
The portion size consumed

Formula:GL=(GI×Carbohydrate content preserving in grams)÷ 100GL = (GI × Carbohydrate content per serving in grams) ÷ 100GL=(GI×Carbohydrate content per serving in grams)÷100

Low GL (≤10) – Minimal effect on blood sugar
Medium GL (11–19) – Moderate impact
High GL (≥20) – Significant blood sugar spike

This means even a low-GI food can have a high glycemic load if eaten in excess.

Example: Low GI Foods with High GL if Overeaten

Food	GI Value	Carbs per Serving	Glycemic Load (GL)
Rolled Oats (1 cup)	55	50g	28 (High)
Brown Rice (1.5 cups)	50	67g	34 (High)
Quinoa (1.5 cups)	53	65g	34 (High)
Chickpeas (2 cups)	28	90g	25 (High)

Eating small portions keeps the glycemic load low, preventing excessive blood sugar spikes.

How to Keep Glycemic Load Low While Eating Low-GI Foods?

Watch Your Portions – Stick to recommended serving sizes instead of eating large amounts of low-GI foods.
Combine with Healthy Fats & Proteins – Adding avocados, nuts, olive oil, or protein sources helps slow down glucose absorption.
Prioritize Fiber-Rich Choices – Foods like vegetables, legumes, and seeds have lower glycemic loads, even in larger portions.
Balance Meals – Avoid excessively large servings of grains or starchy foods in one meal to prevent excessive blood sugar elevations.

Balance is Key

Low-GI foods are beneficial, but portion control is crucial.
Overeating, even low-GI foods, can lead to high glycemic loads, raising blood sugar.
Pairing with healthy fats, proteins, and fiber ensures better glucose control.

Being mindful of portion sizes is important. Focus on a balanced diet to maximize the benefits of low-GI foods. This helps in keeping the glycemic load in check.

Healthy Fats: The Best Sources for Optimal Health

Including healthy fats in your diet helps:

Stabilize blood sugar (slows glucose absorption)
Reduce inflammation (important for heart health)
Support brain function (essential for cognitive health)

The recommended daily fat intake for a 70 kg person is around 70–90 grams per day, ideally from healthy sources.

Best Sources of Healthy Fats

Food	Type of Fat	Recommended Daily Intake
Avocado	Monounsaturated	½ avocado (15g fat)
Olive Oil	Monounsaturated	1–2 tbsp (14g fat/tbsp)
Coconut Oil	Saturated	1 tbsp (14g fat)
Salmon	Omega-3	100g serving (13g fat)
Chia Seeds	Omega-3, Fiber	2 tbsp (9g fat)
Flaxseeds	Omega-3, Fiber	2 tbsp (8g fat)
Walnuts	Omega-3	¼ cup (18g fat)
Almonds	Monounsaturated	¼ cup (14g fat)
Dark Chocolate (85%+)	Monounsaturated	30g (12g fat)

How to Combine Low-GI Foods and Healthy Fats for Better Health

To maintain steady blood sugar and optimize health, combine low-GI foods with healthy fats in meals.

Example 1 (Breakfast):

Scrambled eggs (fat & protein) with sautéed spinach (low-GI)
A slice of whole-grain toast (low-GI) with avocado (healthy fat)

Example 2 (Lunch):

Grilled salmon (healthy fat & protein)
Quinoa and lentil salad (low-GI carbs)
Olive oil dressing (healthy fat)

Example 3 (Snack):

Chia seed pudding (low-GI) made with almond milk (healthy fat)

Example 4 (Dinner):

Grilled chicken with roasted carrots and cauliflower (low-GI)
Side of brown rice (low-GI) with olive oil drizzle (healthy fat)

Final Thoughts: Why Low-GI Foods and Healthy Fats Matter

Switching to a low-GI, healthy, fat-rich diet can:

Prevent diabetes and insulin resistance
Keep energy levels stable
Reduce cravings and overeating
Support heart and brain health

Simple Guidelines to Follow

Prioritize whole, unprocessed foods (vegetables, legumes, nuts, whole grains).
Pair low-GI carbs with healthy fats for sustained energy.
Limit refined sugars and high-GI foods (white rice, white bread, processed snacks).
Incorporate omega-3-rich fats like salmon, flaxseeds, and walnuts.

You can stabilize your blood sugar by making small changes to your daily eating habits. You can also improve insulin sensitivity and promote long-term health.
