What is the menopause? Menopause is the name given to the time when women’s ovaries slowly stop working. This leads to a fall in levels of the oestrogen and is thought to be related to a variety of symptoms such as hot flushes, irritability and joint pains.

Weight issues • A BMI of 25-26 is fine. • Metabolic rate may be lower at middle age so less food is required than when younger. • Some causes of extra weight: – fall in metabolic rate – less active – creeping obesity – HRT does not lead to weight gain per se

Does reaching the menopause have to equal central adiposity? No! • Physical activity alone can offset central weight gain as measured by waist circumference • Maintaining a normal weight will help

Physical activity: the 3 S’s Stamina: an extra 2000 steps a day will burn up 100 calories which is responsible for creeping obesity. Buy a pedometer! Suppleness: if you don’t use it you loose ittry Yoga, Pilates, Stretching Strength: pump it up with those baked bean cans

Fats! Benefits of reducing fat in the diet: – improved lipid profile – reduced incidence of heart disease – weight loss – possible reduced incidence of dementia – reduced breast tenderness

Types of fats • Benefits are seen with following the Mediterranean diet- fruit and vegetables, olive oil, fish and some wine! • Monosaturated fats are termed ‘good fats’and include rapeseed oil (canola), olive oil, avocado oil, linseed oil, hempseed oil (these are also good vegeterian sources of omega 3 oils) • Avoid trans fats

4.Fruit and Vegetables It is recommended to eat at least 5 portions of fruit and vegetables daily. Fruit and vegetable intake is associated with increase BMD, increase antioxidant levels and provides the mood regulating mineral, magnesium, which is often low in menopausal women.

What is osteoporosis?

“It is a progressive systemic skeletal disease characterised by low bone mass and microarchitectural deterioration of skeletal tissue. It results in bone fragility and an increased susceptibility to fracture. It is a silent disease, such that the deterioration of skeletal tissue occurs with no outward sign until fracture occurs”

Diet for osteoporosis • A balance of nutrients is important, including fruit and vegetables. • Have a diet rich in calcium with enough vitamin D to help you absorb the calcium. Calcium is found in dairy foods, tofu, green vegetables, beans and fish that contain edible bones.

Calcium supplements • Most benefit seen for calcium in late menopause and in elderly. • Seems little effect during peak of the menopause. • 500mg supplement is sometimes recommended if there is osteoporosis (UK NOS) • May be best taken with Zn, Cu, Mn, Mg and vitamin D • A soluble form of calcium is best • Do not exceed 2000mg calcium from diet and supplement

Other factors affecting bone health • • • • • •

Vitamin D and oily fish

• UK recommendation is to eat 2 portions of fish a week, one of them should be oily. This will provide some vitamin D and essential fatty acids that help protect the heart. • Vitamin D is found also in eggs, butter and margarine and fortified breakfast cereals. • 10-15 mins sun on face and forearms during summer months is also recommended • In the UK, people over 60 are recommended to take a 10 mcg supplement daily.

Benefits of fish oil • Reduces CVD risk, especially beneficial for reducing subsequent heart attack after first, and in Type 11 diabetes. • Reduces heart fibrillation. • Reduces blood pressure. • Reduces triglyceride level. • Anti-coagulatory (will help prevent clotting). • Anti-inflammatory (especially beneficial to raise ratio of omega 3 to omega 6). • May help to reduce symptoms of rheumatoid arthritis. • May help reduce risk of age-related macular degeneration and dry eye syndrome.

7.Eat more starch! • Dietary advice for maximum health benefits include the recommendation to eat 50% of calories as carbohydrate, with as much as possible coming from unrefined sources. • A starchy and fibre rich carbohydrate should be eaten at each meal. This will help keep bowels healthy, will provide a long lasting supply of energy and may help reduce cholesterol levels.

8. Alcohol! Excess alcohol is associated with:. • hot flushes • osteoporosis • weight gain. • Cancer, especially of the breast Moderate drinking seems to be cardioprotective after the menopause.

Caffeine Excess caffeine during the menopause may be associated with : • sleep problems • anxiety • reduced bone density • blood pressure • Parkinson’s disease (taken with HRT)? • breast tendernes Black coffee seems to be the main concern

9. Salt! • Salt can lead to high blood pressure. • Salt may cause hypercalciurea, thus predisposing to osteoporosis. • A high salt diet may also exacerbate bloating and fluid retention. To cut down: Reduce the amount of processed foods you eat and don’t add salt to your food (use more herbs and spices).

10. Phytoestrogens Shown Benefit: • Some menopausal symptoms e.g. hot flushes ß Prostrate cancer ß Cholesterol lowering Some evidence: ß Bone health ß PMS ß Breast and endometrial cancer, ß Cognitive function ß Blood pressure ß CVD in postmenopausal women

Isoflavone content • • • • • •

Soya milk 10mg/100ml Soya yogurt 10mg/100ml TVP 33mg/100g Soya cheese 7mg/100g Tofu 27mg/100g Red clover supplement 40mg 40-60mg required /day for any effect

Food Sources of phytoestrogen • Soya and soya products such as soya milk, tofu, soya yogurts • Vegetables and fruit

• Seeds especially flax seeds (linseed). • Nuts • Peas, beans and lentils

Other alternatives to HRT • Menopause designer supplements: Expensive and may not be the best. • Herbals e.g. Black Cohosh, Chinese angelica, Agnus Castus, Don quoi, Wild yam, St john’s wort, Hops, Ginseng: May have a role, but watch safety and seek medical advice if on other medication. • Isoflavone supplements e.g. Red clover: Not as effective as dietary sources • Other supplements e.g. vitamin E, EPO, vitamin B6: may be helpful for symptoms such as breast tenderness and bloating. • Healthy lifestyle- raises the threshold above which symptoms appear
