🩺 Cholesterol Explained: HDL, LDL, Triglycerides & Total — Complete Guide

Visual comparison of HDL, LDL, and Triglycerides — the three key types of cholesterol that affect heart health.

Quick Facts

Read ~10 min

• Cholesterol is a fat-like substance made by the liver and found in foods.

• Balance matters: HDL (good) ↑, LDL (bad) ↓, Triglycerides ↓.

• Goal: Total <200 mg/dL for most adults.

Targets

Total <200

LDL <100 • HDL ≥60 • TG <150

🧬 What is Cholesterol?

Cholesterol is a fatty, wax-like compound present in all the cells of your body, essential for various bodily functions. Your liver makes most of it, and some comes from food. It is essential for:

• Building cell membranes 🧱
• Making hormones: testosterone, estrogen, cortisol ⚖️
• Producing vitamin D ☀️

The scientific family name is cholestane derivatives.

🟢 HDL — High-Density Lipoprotein (Good Cholesterol)

Function: HDL collects excess cholesterol from blood vessels and carries it back to the liver for disposal — think of it as a “clean-up crew.”

Target: ≥60 mg/dL protective; 40–59 acceptable; <40 men / <50 women = low & risky.

How to raise HDL: aerobic exercise 🏃, stop smoking 🚭, healthy fats (olive oil 🥑, nuts 🥜), moderate alcohol 🍷 (if allowed), maintain healthy weight ⚖️.

🔴 LDL — Low-Density Lipoprotein (Bad Cholesterol)

Function: LDL delivers cholesterol to tissues. Excess deposits in artery walls → plaques (atherosclerosis), raising heart & stroke risk ❤️🧠.

Target: <100 optimal; 100–129 near optimal; 130–159 borderline; 160–189 high; ≥190 very high.

How to lower LDL: reduce saturated/trans fats 🚫, increase soluble fiber (oats, beans 🥣), use plant sterols 🌿, eat nuts 🥜, lose weight ⚖️.

⚡ Triglycerides — TG (Blood Fat for Energy)

Function: Triglycerides store extra calories for energy. High fasting TG increases risk of heart disease and pancreatitis.

Target: <150 normal; 150–199 borderline; 200–499 high; ≥500 very high (pancreatitis risk).

How to lower TG: cut added sugar/refined carbs 🍬🍞, limit alcohol 🍷, lose weight ⚖️, exercise 🏃, eat fatty fish 🐟 / omega-3 (as advised).

🧾 Total Cholesterol

Definition: Total cholesterol = HDL + LDL + ~20% of triglycerides (Friedewald formula).

Target: <200 mg/dL desirable; 200–239 borderline; ≥240 high.

📊 Cholesterol Ranges Table

Measure	Desirable / Normal	Borderline	High / Risk
Total cholesterol	< 200 mg/dL	200–239 mg/dL	≥ 240 mg/dL
LDL ("bad")	<100 mg/dL	100–159 mg/dL	160–189 high, ≥190 very high
HDL ("good")	≥ 60 mg/dL	40–59 mg/dL	<40 men / <50 women low & risky
Triglycerides (TG)	<150 mg/dL	150–199 mg/dL	200–499 high, ≥500 very high

💡 Simple Examples

• LDL 120 + HDL 50 + TG 140 → Total ≈ 50 + 120 + 28 = 198 mg/dL ✅ (desirable)
• LDL 170 + HDL 38 + TG 220 → High risk ❌; LDL high, HDL low, TG high; doctor intervention needed

💚 How to Reduce Cholesterol — The Full Natural Approach ✅

You can significantly lower cholesterol through diet, exercise, and daily habits. Below are proven strategies with practical tips and examples.

🥣 1) Eat More Soluble Fiber

Soluble fiber traps cholesterol in the gut so it leaves your body instead of entering your blood. Aim for 25–35 g of total fiber daily, including 5–10 g of soluble fiber.

• Examples: oats (porridge), barley, psyllium husk, beans, lentils, chickpeas, apples, oranges, carrots, aubergine (eggplant), okra.
• 💡 Breakfast tip: 1 cup cooked oats + 1 tbsp ground flaxseed + 1 apple = a fiber-packed start.

🥑 2) Use Healthy Fats — Replace Saturated & Trans Fats

Reduce saturated fat (butter, ghee, fatty red meat, full-fat dairy) to <7% of daily calories and eliminate trans fats (partially hydrogenated oils). Replace them with:

• Olive oil (extra virgin), canola oil, avocado, nuts (almonds, walnuts), seeds (flax, chia).
• 🐟 Fatty fish (salmon, sardines, mackerel) 2–3 times/week for omega-3s — good for triglycerides.

🌿 3) Add Plant Sterols & Stanols

Plant sterols block cholesterol absorption. Foods or fortified spreads with ~2 g/day can lower LDL by ~5–15%. Look for fortified margarines and functional foods — check labels.

🥜 4) Eat More Nuts & Seeds

A small handful (20–30 g) of nuts daily — almonds, walnuts — can modestly lower LDL.

💡 Snack idea: 10–12 almonds + a small orange in the afternoon.

🍲 5) Eat Legumes Every Day

Beans, lentils, and chickpeas are high in fiber, filling, and inexpensive. Regular intake lowers LDL.

💡 Tip: Add 1 cup cooked lentils into soups or salads.

🍞 6) Cut Down Refined Carbs & Added Sugar

Refined carbs (white bread, sweets, sugary drinks) raise triglycerides and lower HDL. Swap with whole grains and natural fruit.

🍷 7) Moderate Alcohol

Small amounts of alcohol (esp. red wine) can slightly raise HDL, but may raise triglycerides. If drinking: up to 1 drink/day for women, 2/day for men, and check with your doctor.

⚖️ 8) Lose Weight if Overweight

Losing 5–10% of body weight often reduces LDL/triglycerides and improves HDL.

💡 Example: If you weigh 90 kg, a 5–9 kg loss benefits heart health.

🏃 9) Exercise Regularly

Aim for 150 min/week of moderate aerobic activity (30 min × 5 days) or 75 min vigorous activity. Include strength training 2x/week. Physical activity increases HDL and lowers LDL/triglycerides.

⚠️ Why Vegetarians Can Still Have Heart Attacks

• ❌ Diet high in refined grains (white rice, bread, pasta) and sugary foods raises bad cholesterol and triglycerides.
• ❌ Excessive use of saturated fats like ghee, butter, coconut, and palm oil increases LDL cholesterol.
• ❌ Lack of omega-3 fatty acids (EPA/DHA) — protective fats often missing in strict vegetarian diets.
• ❌ Nutrient deficiencies (Vitamin B12, protein) may raise homocysteine or affect heart health.
• ❌ Sedentary lifestyle, stress, smoking, or family history can contribute regardless of diet.
• ❌ Over-reliance on processed vegetarian foods (snacks, bakery items, frozen meals) adds trans fats, sugar, and salt.

✅ Takeaway: A vegetarian diet is heart-healthy only when it focuses on whole foods — vegetables, fruits, legumes, whole grains, nuts, seeds — and combines exercise and healthy lifestyle habits.

🍎🍗 Foods to Eat and Foods to Avoid — Clear Lists with Examples

✅ Top Foods to Include (Helpful):

• Oats, barley, psyllium

• Beans, lentils, chickpeas

• Fatty fish: salmon, sardines, mackerel 🐟

• Olive oil, avocado, nuts (almonds, walnuts) 🥑🥜

• Fruits: apples, citrus, berries 🍎🍊🍓

• Vegetables: leafy greens, aubergine, okra, carrots 🥬🥕

• Seeds: flaxseed, chia 🌱

• Green tea, garlic 🍵🧄 (some benefit)

⚠️ Foods to Limit / Avoid:

• Fried foods, fast food 🍟

• Processed meats: sausages, salami 🥓

• Fatty red meat (regularly)

• Full-fat dairy (butter, cream) 🧈

• Baked goods with trans fats 🥐

• Sugary drinks & sweets 🥤🍬

• Excess alcohol 🍷

• High-salt processed snacks 🧂

🥦🍗 Vegetarian vs Non-Vegetarian — Which is Better?

Both vegetarian and non-vegetarian diets can be heart-healthy — it depends on your food choices.

• Vegetarian diets (plant-based) are high in fiber and low in saturated fat — usually lower LDL. But they can be unhealthy if relying on refined carbs, fried snacks, and sweets.
• Non-vegetarian diets can be healthy if focused on lean proteins (fish, skinless poultry) and limited red/processed meat. Fatty fish rich in omega-3 is great for triglycerides 🐟.

Bottom line: Choose whole, unprocessed foods. Vegetarian diets naturally help cholesterol when balanced; non-veg can be equally good if you pick fish and lean meats and avoid fatty cuts.
