Nutrition — Eating Right in a World Designed to Make You Sick
The modern food environment is engineered by billion-dollar companies to override your natural hunger signals, make you addicted, and keep you buying. Understanding how food actually works — and what the food industry doesn't want you to know — is the foundation of real health.
The Processed Food Problem — What's Actually In Your Food
Ultra-Processed Food (UPF) — The Biggest Health Crisis Nobody Talks About
Ultra-processed foods (UPFs) are industrial formulations — typically combining refined sugars, refined grains, fats, salt, flavour enhancers, emulsifiers, and a cocktail of additives to create products designed to be hyperpalatable, cheap to produce, and long shelf-life.
NOVA Classification system (used by WHO):
Group 1: Unprocessed/minimally processed ✅
Fresh vegetables, fruits, legumes, meat, fish, eggs, milk, nuts
Group 2: Processed culinary ingredients ✅
Oils, ghee, butter, salt, flour, sugar (used in cooking)
Group 3: Processed foods ⚠️ (occasional)
Canned vegetables, cheese, salted nuts, smoked fish
Made by adding salt, sugar, oil to Group 1 foods
Group 4: Ultra-processed foods ❌ (minimise drastically)
Soft drinks, packaged chips, biscuits, instant noodles,
packaged bread, breakfast cereals, processed meats (sausage,
nuggets), flavoured yogurts, energy drinks, fruit juices,
ready-to-eat meals, fast food, margarine
What Makes UPF So Harmful
Engineered for addiction:
The "bliss point" — the exact combination of sugar, fat, and salt that maximises pleasure and minimises satiety. Processed food companies employ food scientists specifically to find this point. This is why you can eat an entire packet of chips but feel unsatisfied in a way you never would after eating a meal of rice, dal, and vegetables.
Hyperpalatable = overrides satiety signals:
Your brain's satiety mechanism (leptin + GLP-1 hormones) evolved for whole foods. UPF delivers more calories per bite than any naturally occurring food, arriving too fast for satiety signals to register. You're full before the hormones catch up — 20 minutes later.
Common harmful additives in packaged food:
Emulsifiers (destroy gut lining):
Polysorbate-80, carrageenan, lecithin in excess
Research shows these degrade the mucus layer protecting gut lining
Artificial flavours:
MSG variants (disodium inosinate, disodium guanylate)
Natural flavour = can be from anything, animal or chemical
Preservatives:
Sodium benzoate + Vitamin C (ascorbic acid) → forms benzene (carcinogen)
BHA/BHT: Suspected endocrine disruptors
EDTA: Chelates minerals, reduces absorption
Refined vegetable oils (reused/heated):
Soybean, sunflower, canola, corn oil (high in omega-6)
When heated to frying temperatures → form aldehydes and 4-HNE
These are toxic to brain cells and linked to neurodegeneration
Restaurant and street food reuse frying oil repeatedly
Artificial sweeteners:
Aspartame, sucralose, saccharin → don't reduce calories net
Kill gut bacteria, increase glucose intolerance
Trigger insulin response via gut-brain axis
Refined sugar by many names:
High fructose corn syrup, glucose syrup, maltodextrin,
dextrose, cane sugar, agave, barley malt — ALL are sugar
A product can list 5 types of sugar and each appears minor
Understanding Macronutrients — Not the Diet Industry Version
Carbohydrates — The Most Misunderstood Macronutrient
Not all carbohydrates are equal:
Simple/Refined (eat less):
White sugar, white rice (refined), maida, processed cereals
→ Rapid glucose spike → insulin spike → fat storage → crash
→ Glycemic Index: 70+
Complex/Whole (eat more):
Brown rice, whole wheat, oats, millets (ragi, jowar, bajra)
Sweet potato, legumes, vegetables
→ Slow glucose release → sustained energy → feeds good gut bacteria
→ Glycemic Index: 35-65
Resistant starch (eat regularly):
Cooked and cooled rice/potato → starch becomes resistant
Acts like fibre, feeds gut bacteria, doesn't spike glucose
Cooling overnight maximises RS content
Glycemic Load vs Glycemic Index:
GI measures speed of glucose spike
GL = GI × actual carbs in portion
Watermelon: High GI (72) but low GL (6) because mostly water
→ GL is more practically useful than GI
Protein — How Much You Actually Need
Requirements:
Sedentary adult: 0.8g per kg body weight
Active person: 1.2-1.6g per kg
Building muscle: 1.6-2.2g per kg
70kg person, active: 84-112g protein per day
Best sources (Indian context):
Dal + rice combination: Complete protein (complementary amino acids)
Paneer: 18g per 100g, excellent quality
Curd/yogurt: 10g per 100g, probiotic benefit too
Eggs: Most bioavailable protein (97%), 6g per egg
Chicken: 25-30g per 100g, lean
Fish: 20-25g + omega-3 fatty acids
Moong dal: 24g per 100g dry, easily digestible
Soy/tofu: 36g per 100g dry, complete plant protein
Chickpeas: 19g per 100g dry
Protein quality — PDCAAS score:
Eggs (1.0), Casein (1.0), Soy (1.0) → complete
Wheat (0.4), Rice (0.5) → incomplete alone
Dal + Rice → combined PDCAAS ~0.9 → nearly complete
Myth: "Too much protein harms kidneys"
True only for people with pre-existing kidney disease
For healthy adults: up to 2.5g/kg is well-tolerated
Fats — What the Low-Fat Era Got Wrong
The 1980s-1990s "fat is bad" era was one of the biggest nutritional disasters. Food companies removed fat (which tastes good) and replaced it with sugar and refined carbs. Result: obesity and diabetes epidemic.
Fats to eat more of:
Saturated fats (in moderation — not the villain):
Ghee: One of the best cooking fats — stable at high heat,
rich in butyrate (gut healing), conjugated linoleic acid
Coconut oil: Medium-chain triglycerides, stable at medium heat
Full-fat dairy: If tolerated, more nutritious than low-fat
Monounsaturated fats:
Olive oil: Extra virgin for dressing/low-heat, rich in polyphenols
Nuts: Almonds, cashews, peanuts, walnuts
Avocado: Rich in oleic acid
Omega-3 polyunsaturated:
Fatty fish (salmon, sardines, mackerel, rohu, katla)
Flaxseeds (ground, not whole — can't digest whole)
Chia seeds
Walnuts
→ Target 2g EPA+DHA per day from food or supplement
Fats to minimise/avoid:
Trans fats (partially hydrogenated oils):
Now banned in most countries but still in some Indian products
Vanaspati, dalda, some margarine
Also formed when vegetable oils are heated repeatedly
→ Strongly linked to cardiovascular disease
Omega-6 excess (from vegetable oils):
Sunflower, safflower, soybean, corn oil — all high omega-6
Modern diet: Omega-6:Omega-3 ratio is 15-20:1
Healthy ratio: 4:1 or less
Excess omega-6 drives inflammation
→ Switch primary cooking oil to ghee, coconut oil, or olive oil
Outside Food — The Real Risk Assessment
Restaurant Food Problems
Maida (refined white flour) everywhere:
Indian restaurants use maida in: naan, bhatura, puri, samosa,
spring roll wrapper, most Chinese-Indian dishes, thickening gravies
→ Spikes blood sugar, stripped of fibre, bleached with benzoyl peroxide
Reused frying oil:
Economically rational for restaurants — extremely toxic
Each reheating cycle creates more trans fats and carcinogenic compounds
Avoid: all fried items at roadside and mid-range restaurants
Excess salt:
Restaurant food has 3-5× the sodium of home cooking
Responsible for significant hypertension in urban populations
Artificial colours in street food:
Bright orange/red sweets, mithai, gola ice, pani puri water
Most use non-food-grade colours
Many are coal-tar dyes not approved for food use
MSG and flavour enhancers:
Ubiquitous in Chinese, fast food, packet masalas
No proven harm at food doses for most people
BUT combined with high sodium → excess salt intake
Hidden sugar in savoury food:
Tomato ketchup (25% sugar), barbecue sauce, Chinese sauces,
most restaurant dressings, packaged chutneys
Making Smarter Restaurant Choices
Better choices available:
✓ Dal-rice combinations (complete protein + fibre)
✓ Grilled/tandoor items over fried
✓ Roti over naan (whole wheat over maida)
✓ Raita adds probiotics
✓ Ask for less oil/ghee when ordering sabzi
✓ Choose dry preparations (bhuna, tandoori) over creamy/oily
✓ Idli/dosa over puri/bhature (fermented, steamed/lightly cooked)
Reading your plate:
Orange-red colour + not fresh vegetables → artificial colour
Extremely soft potato in sabzi → aluminium used to soften quickly
Very white khoya/paneer → chalk/starch adulteration common
Unnaturally bright green chutney → synthetic colour
Indian Diet — Ancient Wisdom, Modern Application
Traditional Indian food, when cooked at home with whole ingredients, is remarkably aligned with modern nutritional science. The problems come from the modern processed food invasion and restaurant versions of traditional dishes.
Traditional strengths:
Dal + rice: Complete protein, balanced carbs
Fermented foods: Idli, dosa, curd, pickle — excellent probiotics
Spices with health properties:
Turmeric (curcumin): Anti-inflammatory, antioxidant
Ginger: Anti-nausea, anti-inflammatory, digestive aid
Coriander: Antifungal, digestive
Fenugreek (methi): Blood sugar regulation
Ajwain: Digestive, carminative
Asafoetida (hing): Anti-flatulence, digestive
Seasonal and local eating: Naturally more varied microbiome support
Ghee: Butyrate, fat-soluble vitamin absorption, stability
Millets: Higher fibre, protein, and micronutrients than rice or wheat
Micronutrients — The Most Common Deficiencies in India
Vitamin D: Deficient in 60-80% of Indians despite living in a sunny country
→ Reason: We avoid sun during peak hours, covered clothing, indoor work
→ Symptoms: Fatigue, bone pain, frequent infections, depression, muscle weakness
→ Solution: 15-20 minutes sunlight on arms/legs between 10am-2pm daily
OR Vitamin D3 (2000-4000 IU daily) with K2
Iron: Most common deficiency globally, especially women
→ Symptoms: Fatigue, pale skin, cold hands/feet, brittle nails, brain fog
→ Best sources: Red meat, organ meats (liver), spinach with Vitamin C
→ Note: Plant iron (non-heme) needs Vitamin C for absorption
Coffee/tea with meals blocks iron absorption by 60-70%
Vitamin B12: Deficient in 50-80% of vegetarians/vegans
→ Symptoms: Numbness/tingling in hands/feet, fatigue, memory issues, elevated homocysteine
→ Vegetarian sources: Almost none (dairy has minimal amounts)
→ Supplement: 500-1000mcg methylcobalamin sublingual daily
→ This is non-negotiable for vegetarians — cannot get adequate from food
Magnesium: Deficient in ~50% of people (poor soil, processed food)
→ Functions: 300+ enzymatic reactions, sleep, muscle function, stress
→ Symptoms: Muscle cramps, poor sleep, anxiety, constipation
→ Best forms: Magnesium glycinate (sleep/anxiety), citrate (constipation)
Omega-3 (EPA/DHA): Low in most vegetarians, low in non-fish eaters
→ Critical for brain health, inflammation control, cardiovascular health
→ Vegetarian source: Algae-based omega-3 (what fish eat — go to the source)
→ 2g EPA+DHA daily is the therapeutic target
Iodine: Deficiency increasing in some populations despite iodized salt
→ Use iodized salt, eat dairy and fish
→ Don't over-supplement (too much also causes thyroid issues)
Practical Eating Framework
The Plate Method
Ideal plate composition:
50%: Non-starchy vegetables (sabzi, salad, greens)
25%: Protein (dal, eggs, paneer, chicken, fish)
25%: Complex carbohydrates (rice, roti, millets)
Add: 1-2 tbsp healthy fat (ghee, olive oil drizzle)
Small portion fermented food (curd, pickle)
Eating Timing
Eat with the sun (circadian nutrition):
Breakfast: 7-9am (largest meal or substantial)
Lunch: 12-2pm (largest meal of day ideally)
Dinner: Before 7-8pm (lightest meal, mostly vegetables + protein)
Intermittent fasting (16:8 approach):
Eat within an 8-hour window (e.g. 10am-6pm or 11am-7pm)
16 hours fasting promotes: Autophagy, insulin sensitivity,
weight management, gut rest
Start with 12 hours, extend gradually
Not for: children, pregnant women, history of eating disorders
Food Shopping Guidance
The perimeter rule: Healthiest foods in supermarkets are around the perimeter
→ Produce (vegetables, fruits), dairy, meat, fish
Centre aisles: Mostly packaged processed food
Reading ingredient lists:
Ingredients are listed by quantity (most → least)
If sugar/maida/refined oil is in top 3 → ultra-processed
Aim: 5 ingredients or fewer, all recognisable as food
"Contains no added preservatives" ≠ healthy
"Natural flavours" ≠ safe or identifiable
"Made with real fruit" ≠ significant fruit content
"Multigrain" ≠ whole grain (can be multiple refined grains)
"Low fat" ≠ low calorie (usually higher sugar to compensate)
