Eggs and dairy spent decades on the wrong side of dietary advice, and the
correction has been quiet. The cholesterol you eat is not the main driver of the
cholesterol in your blood for most people — which changed the eggs conversation
considerably.
Eggs
One of the most complete foods available: high-quality protein, choline, vitamin D, B12,
and lutein. Nearly all of it is in the yolk. Eating only whites throws away most of the
nutrition to avoid a fear that has largely not held up.
For most healthy people, an egg a day is fine. If you have diabetes,
familial high cholesterol, or existing heart disease, the picture is less settled and worth
a specific conversation with your doctor rather than a rule from the internet.
- Cook them gently. Soft-scrambled, poached or boiled keeps more of the
useful fats intact than hard frying.
- Yolk colour tells you about the hen's feed, not nutrition. A deep orange
yolk usually means a varied diet, not automatically a better egg.
- Freshness test: in a bowl of water, fresh eggs sink and lie flat. Old
eggs stand up or float.
Milk, yoghurt and cheese
Fermented dairy behaves differently from plain milk. Yoghurt, kefir, dahi
and aged cheese contain live cultures, and fermented dairy consistently performs better in
research on blood pressure and blood sugar than milk does.
- Yoghurt and kefir — live cultures, easier to digest than milk for many
people, and useful after a course of antibiotics.
- Paneer and cottage cheese — high protein, low lactose, very filling.
- Ghee — clarified butter. Almost no lactose or casein, high smoke point,
so it suits high-heat cooking better than butter. Still nearly all fat, so it is a cooking
medium, not a health tonic.
- Hard aged cheese — naturally very low in lactose, because the bacteria
consumed it during ageing. Often tolerated by people who cannot drink milk.
If milk upsets your stomach, do not write off dairy.
Lactose intolerance is a spectrum, and most people who have it handle yoghurt, kefir, paneer
and hard cheese comfortably. Try those before switching everything to alternatives.
Full fat or low fat?
Honestly, less settled than either side claims. Full-fat dairy is more filling and the
observational evidence has not shown the harm that was once assumed. Low-fat saves calories
but often adds sugar in flavoured products.
The clearer advice: plain over flavoured, either way. A flavoured yoghurt
can carry more sugar than a dessert, and that is a bigger issue than the fat percentage.
Who should be careful
- Lactose intolerance: start with fermented and aged dairy rather than
eliminating everything.
- Milk protein allergy is a different condition from lactose intolerance
and does require full avoidance, including ghee in severe cases.
- High cholesterol or heart disease: butter, cream and full-fat cheese are
high in saturated fat. Portion matters more than banning.
- Pregnancy: avoid unpasteurised milk and soft mould-ripened cheeses.
- Acne: the evidence linking skim milk in particular to acne in some
people is reasonable. If your skin reacts, it is worth a trial without it.

pregnant, managing a diagnosed condition, or taking medication, talk to your doctor before
making a large change to your diet.
