Chapter 4 – <strong>Milk</strong> <strong>and</strong> dairy products as part of the diet 151<br />

(95 percent CI: 0.78–0.98) for cerebral <strong>in</strong>farction. Consumption of total dairy, fullfat<br />

dairy <strong>and</strong> milk were not associated with stroke risk. In the second study, which<br />

looked at dietary prote<strong>in</strong> sources <strong>and</strong> the risk of stroke, Bernste<strong>in</strong> et al. (2012)<br />

found that compared with one serv<strong>in</strong>g of red meat/day, one serv<strong>in</strong>g of low-fat<br />

dairy/day was associated with an 11 percent lower risk of stroke (95 percent CI:<br />

5 percent–17 percent), <strong>and</strong> one serv<strong>in</strong>g of whole-fat dairy/day with a 10 percent<br />

lower risk (95 percent CI: 4 percent–16 percent).<br />

4.8.4 Other dairy products <strong>and</strong> risk of cardiovascular disease<br />

There is a paucity of studies exam<strong>in</strong><strong>in</strong>g <strong>in</strong>dividual dairy food items <strong>and</strong> CVD risk<br />

(Elwood et al., 2010). Butter has a higher concentration of milk fat than any other<br />

dairy product, <strong>and</strong> is cholesterolemic (Tholstrup, 2006). However, controlled studies<br />

have demonstrated that milk <strong>and</strong> butter have similar cholesterolemic effects;<br />

the effects on other CHD risk markers have not been fully elucidated (Tholstrup,<br />

2006). An <strong>in</strong>consistency between results from cohort studies <strong>and</strong> case-controlled<br />

studies with respect to butter has been highlighted by Elwood et al. (2010): a metaanalysis<br />

of data from three cohorts suggested a possible reduction <strong>in</strong> vascular disease<br />

risk (0.93; 95 percent CI: 0.84–1.02), although this was not statistically significant<br />

(P = 0.33), while two case-control studies suggested an <strong>in</strong>crease of vascular disease,<br />

<strong>and</strong> one case-control study an <strong>in</strong>crease <strong>in</strong> peripheral arterial disease from the consumption<br />

of butter. A more recent study (Goldbohm et al., 2011) reported a slightly<br />

<strong>in</strong>creased risk of all-cause <strong>and</strong> IHD mortality for both butter <strong>and</strong> dairy fat <strong>in</strong>take<br />

(per 10 g/day; rate ratio mortality = 1.04; 95 percent CI: 1.01–1.06) only <strong>in</strong> women. As<br />

Elwood et al. (2010) concluded, the ma<strong>in</strong> message of these data is that the evidence<br />

on butter <strong>and</strong> the other dairy items is <strong>in</strong>adequate.<br />

Ghee, an important source of fat <strong>in</strong> the Indian diet derived from cow <strong>and</strong> buffalo<br />

milk, is rich <strong>in</strong> SFAs <strong>and</strong> cholesterol (Nath <strong>and</strong> Ramamurthy, 1988; Rawashdeh,<br />

2002; Mohammadifard et al., 2010). High consumption of vegetable ghee, 38 clarified<br />

butter (Indian ghee) <strong>and</strong> milk, <strong>in</strong> conjunction with a sedentary lifestyle <strong>and</strong> higher<br />

BMI have been reported to be significant risk factors for CVD <strong>in</strong> Indians (S<strong>in</strong>gh<br />

et al., 1996). However, Indian men consum<strong>in</strong>g 1 kg or more of ghee per month<br />

have been found to have a significantly lower prevalence of CHD than those who<br />

consumed less than 1 kg/month (Gupta <strong>and</strong> Prakash, 1997). Shankar et al. (2002,<br />

2005) found that consumption of ghee at the level of 10 percent of dietary energy<br />

<strong>in</strong> a vegetarian diet had no effect on serum lipid profiles or lipoprote<strong>in</strong> profiles <strong>in</strong><br />

healthy young subjects.<br />

Evidence on cheese <strong>and</strong> vascular disease is also limited (Elwood et al., 2010).<br />

Although six cohort studies evaluat<strong>in</strong>g cheese <strong>and</strong> CVD risk were available, sufficient<br />

data for a meta-analysis were given <strong>in</strong> only two, yield<strong>in</strong>g an overall estimate of<br />

risk from cheese of 0.90 (95 percent CI: 0.79–1.03) (Elwood et al., 2010). Tholstrup<br />
