The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

Are mammograms safe and effective?

This post includes a synopsis of a paper published in the Cochrane Database of Systematic Reviews 2011 Jan 19;(1):CD001877 and a recipe for bacon, spinach and sweet potato salad.

The objective of the review was to assess the effect of screening for breast cancer with mammography on death rates and disease. 600,000 women were included in the analyses.

The review found:
(a) For every 2000 women invited for screening throughout 10 years, only one will have her life prolonged.
(b) For every 2000 women invited for screening throughout 10 years, 10 healthy women, who would not have been diagnosed if there had not been screening, will be treated unnecessarily.
(c) For every 2000 women invited for screening throughout 10 years, more than 200 women will experience important psychological distress for many months because of false positive findings.

To conclude: It is thus not clear whether screening does more good than harm. To help ensure that the women are fully informed of both benefits and harms before they decide whether or not to attend screening, Cochrane have written an evidence-based leaflet for lay people that is available in several languages on

Recipe of the day

Bacon, Spinach and Sweet Potato Salad

3 cups peeled and diced sweet potatoes
Hickory Smoked Breakfast Bacon
Food Mall: Bacon
1 tbsp coconut oil
1 apple diced
8 strips of bacon, diced
2 leeks, thinly sliced
6 oz of fresh baby spinach
Handful of sliced almonds for garnish

¼ cup olive oil
1 tbsp apple cider vinegar
1 tsp spicy brown mustard
Fresh ground black pepper to taste
1 tbsp of dried basil
Pinch of cayenne pepper

Preheat your oven to 400. Toss the diced sweet potatoes with the coconut oil and spread evenly on a baking sheet. Bake in your preheated oven for 20 minutes. While the sweet potatoes are baking, cook the diced bacon in a large skillet. Once the bacon is crispy, add the sliced leeks in with the bacon and saute for another 4-5 minutes. Put your spinach in a large salad bowl and add the bacon and leek mixture. Toss well, letting the warm bacon wilt the spinach. Add the apples and sweet potatoes to the salad and toss together. In a separate bowl whisk together the salad dressing ingredients. Pour over the salad, mix well and garnish with the sliced almonds.
