Questions to ask when choosing a weight loss program…

1. Has a registered dietitian helped to design the program or is one available to talk with you?

2. Is the recommended weight loss more than 2 pounds per week?

3. Does the program provide at least 1200 Calories (5000 kilojoules) per day for women and 1500 Calories (6500 kilojoules) per day for men?

4. Does the program depend on special products, special foods, supplements or treatments?

Case Study #3– CHF

• Patient with know history of CHF comes to see you with complaints of increased ankle edema. The patient is on

maximum diuretic therapy, what else can you do for this patient to help her out of this potential crisis?

Nutrition Management of CHF

• Low Salt Diet:

2400mg sodium per day

• Fluid restriction:

1.5L fluid per day

Ask your CHF patient…

• Are you adding salt at the table or in cooking?

• Do you consume canned soups, vegetables or stews?

• Do you eat packaged frozen entrees?

• Do you eat processed cheese

and prepared meats?

• Do you eat out frequently?

Sodium and Food Labels

Using % Daily Value

% Daily Value How Much Sodium?

What does it mean?

< 5% <125mg sodium per serving

A low sodium food that can be enjoyed daily

5-10% 125-250mg sodium per serving

A food that can easily fit into a low sodium diet

11-20% 250-500mg sodium per serving

A food that can be carefully fit into a low sodium diet

>20% >500mg sodium per serving

A high sodium food that should not be consumed daily when following a low sodium diet

Fluid restriction

• Encourage the patient to track their fluid intake daily

•Remind patients that fluids include: Water, coffee, tea, milk, juice, pop, soup,

jello, nutrition supplements, alcohol, ice cream, thin fluids at room temperature

Additional Thoughts on CHFManagement…

• Multivitamin supplementation

• Thiamine supplementation

• Interpreting BMI in the CHF patient

Should I be taking a vitamin B supplement?

Although two recent studies did show that the vitamins cut homocysteine levels, that did not translate into a reduction in the risk for heart attacks or strokes.

I have heard a lot recently about Omega-3 fats…

• AHA recommends 2-3 meals of fish per week to meet omega-3 fatty acid requirements, 1000mg per day, for CVD prevention

Is an Omega-3 supplement a good idea?

• Omega-3 supplements are recommended for those who do not eat fish regularly

• Choosing a supplement:

1000mg capsule 400mg EPA

200mg DHA

600mg total

Take 1-2 times per day.

The DASH Diet• Dietary Approaches to Stop Hypertension

Grains and grain products 7-8 daily Fruits 4-5 dailyVegetables 4-5 dailyLow fat or fat free dairy 2-3 dailyMeats 2 or less dailyNuts,seeds and dry beans 4-5 x per weekFats and oils 2-3 dailySweets 5 per week
